Abstract Objective: To assess the prevalence, intensity, and extent of the impacts on daily performances related to wearing different types of orthodontic appliances. Materials and Methods: A total of 1657 students, 15 to 16 years old, were randomly selected from those attending all secondary schools in Bauru, São Paulo, Brazil. Only those wearing orthodontic appliances at the time of the survey were included. Face-to-face structured interviews were done to collect information about impacts on quality of life related to wearing orthodontic appliances, using the Oral Impact on Daily Performances (OIDP). Adolescents were also clinically examined to assess the type of orthodontic appliance they were wearing. Comparisons, by type of orthodontic appliance and covariables, were performed using nonparametric statistical tests. Results: Three hundred fifty-seven adolescents (36.1% boys and 63.9% girls) undergoing orthodontic treatment participated in the study. The prevalence of condition-specific impacts related to wearing orthodontic appliances was 22.7%. Among adolescents with impacts related to wearing orthodontic appliances, 35.8% reported impacts of severe or very severe intensity and 90.1% reported impacts on only one daily performance, commonly eating or speaking. The prevalence, but not the intensity or the extent, of condition-specific impacts differed by type of orthodontic appliance (P = .001). Conclusions: One in four Brazilian adolescents undergoing orthodontic treatment reported side effects, specific impacts on daily living, related to wearing orthodontic appliances. Such impacts were higher among adolescents wearing fixed rather than removable or a combination of fixed and removable orthodontic appliances. This information could help to inform patients about the frequency and intensity of sociodental impacts during the course of their treatment.

Lab appliances are an integral part of orthodontics, from active treatment to retention. The quality and fit of an appliance can affect the treatment result and stability. AIMS: This study aims to determine common points of failure in orthodontic appliances, and suggest methods to reduce this rate. METHODS: A survey consisting of 23 questions was distributed to active members of the American Association of Orthodontists (AAO) via Survey Monkey. RESULTS: The most common appliance to need an adjustment was the wrap-around retainer, with the Hawley retainer as a close second. The least common appliance needing adjustment was the Essix/clear retainer. Respondents were asked which component of each appliance was most commonly responsible for an ill-fit. For Hawley and wrap-around retainers, clasps were the most common problem at 50%, whereas spring aligners had two components - clasps and labial bows, both at 38%. Ill-fitting Essix/clear retainers had gingival impingement (52%) closely followed by poor posterior seating (43%). CONCLUSIONS: Communication between the orthodontist and lab technician can be improved by establishing a quality assurance protocol for outgoing and incoming cases. The labial bow of Hawley's, wrap-arounds and spring aligners should be clearly demarcated on the casts. Impressions should be free of distortion and casts should be inspected for accuracy. Clear retainers and positioner should be trimmed to avoid gingival impingement. The type of clasp should be selected based on the anatomy of the teeth, and bands should be checked for accuracy of fit.

Every treatment technique in the orthodontic specialty has its own set of advantages. Combining the techniques in an effective manner could result in a synergistic effect. Two such techniques are lingual orthodontics and functional orthopaedic appliances. This case report shows the effective and efficient use of a customized functional appliance, along with lingual orthodontics, in the management of Class II division 1 malocclusion. It emphasizes the importance of combining the benefits of different strategies of orthodontic treatment. CPD/Clinical Relevance: The use of a customized functional appliance along with lingual orthodontics can produce desirable changes in Class II division 1 cases and clinicians should be aware of these advantages.

Full textAbstract:
Traditionally oral appliances i.e. removable orthodontic appliances, bite splints and snoring / sleep apnea appliances are made with alginate impressions and wax registrations. Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, scheduled for conventional orthodontic treatment, served as a study subject. After a precise clinical and radiographic examination, the approach was to digitize the patient’s dental arches and then to correct them virtually by computer. Additive manufacturing was then used to fabricate a mould for a soft customized appliance. The mould was manufactured using stereolithography from Somos ProtoGen O-XT 18420 material. Casting material for the mould to obtain the final appliance was silicone. As a result we managed to create a customized soft orthodontic appliance. Also, the accuracy of the method was found to be adequate. Two versions of the described device were manufactured: one with small and one with moderate orthodontic force. The study person also gave information on the subjective patient adaptation aspects of the oral appliance.

ABSTRACT Objective: To determine whether orthodontic treatment with removable aligners vs fixed orthodontic appliances is associated with a different frequency of orthodontically induced external apical root resorption (OIEARR) when genetic, radiographic, and clinical factors are accounted for. Materials and Methods: Three hundred seventy-two orthodontic patients treated with removable aligners (Invisalign) or fixed appliances were genetically screened for interleukin 1B gene (IL1B) (rs1143634), interleukin 1 receptor antagonist gene (IL1RN) (rs419598), and osteopontin gene (SPP1) (rs9138/rs11730582). Twelve clinical variables, potentially associated with OIEARR, were also considered. Subjects were divided according to the presence of radiographically determined OIEARR (>2 mm). The association between OIEARR and appliance type, and radiographic, clinical and genetic factors, was assessed using backward stepwise conditional logistic regression. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. Results: Reliability of the methods was adequate. Clinical case complexity (American Board of Orthodontics [ABO] Discrepancy Index) (OR: 1.032; 95% CI: 1.005–1.061; P = .021) and extent of incisor apical displacement in the sagittal plane (OR: 1.478; 95% CI: 1.285–1.699; P = .001) were associated with an increased OIEARR risk. After adjusting for associations between clinical/radiographic/genetic factors, there were no statistically significant differences with respect to OIEARR or type of orthodontic appliance used, whether removable aligners or fixed appliances (OR: 1.662; 95% CI: 0.945–2.924; P = .078). Only subjects homozygous for the T allele of IL1RN (rs419598) were more prone to OIEARR during orthodontic treatment (OR: 3.121; CI: 1.93–5.03; P < .001). Conclusions: A similar OIEARR predisposition was identified using either removable aligners (Invisalign) or fixed appliances.

Objectives: To determine the level of compliance with Oral Hygiene Instruction ( OHI) of 12 to 18 years old adolescent patient receiving orthodontic treatment at Dhaka Dental College and Hospital.Materials and Methods : In this descriptive observational study, a total number of 100 patients (37 boys & 63 girls) were selected (with convenient sampling) from Orthodontics and Dentofacial Orthopedics Department in Dhaka Dental College & Hospital. As the number of female patient is higher than that of male patient at Orthodontics and Dentofacial Orthopedics Department in Dhaka Dental College & Hospital and the samples were selected with convenient sampling, the number of female patient was higher in this study.Results: This was an observational study conducted among 100 patients in the department of Orthodontics and Dentofacial Orthopedics, Dhaka Dental College and Hospital. The result of this study indicates that after five month of insertion of orthodontic appliance, 76% patients were good complier with Oral Hygiene instruction (OHI).Conclusion: The insertion of orthodontic appliances can result in changes in the oral environment, such as causing higher concentration of acid-producing bacteria due to the difficulty of performing oral hygiene after the insertion of appliance. Orthodontic appliances can also be associated with white spots, enamel decalcification, periodontal breakdown, and development of carious lesions. Continual plaque build-up may thus jeopardize the continuity of orthodontic treatment and the achievement of successful treatment outcome. So it is very important to give Oral Hygiene Instruction (OHI) at the commencement of orthodontic treatment and close supervision of the patient during treatment.Ban J Orthod & Dentofac Orthop, April 2013; Vol-3, No.2

Full textAbstract:
Orthodontics is dental specialty focused on preventing and treating morphological and functional irregularities of orofacial system in order to establish adequate function of mastication apparatus, good occlusion and pleasant facial appearance. It has been shown that early treatment of orthodontic anomalies during the period of children?s growth is very important. The purpose of early orthodontic treatment is to eliminate or modify deviant skeletal growth and to stimulate adequate dentoalveolar and skeletal development. As known, the treatment of malocclusions should begin in primary or early mixed dentition, since the status of primary dentition has profound effect on the development of permanent dentition. Functional orthodontic appliances are most commonly used in early orthodontic treatment. The aim of this study was to describe a new prefabricated polyurethane myo-functional appliance clinically proved to be very effective.

ABSTRACT Objective To evaluate the perception of esthetic orthodontic appliances by means of eye-tracking measurements and survey investigation. Materials and Methods En face and close-up images with different orthodontic appliances (aligner appliance [a], aligner appliance and attachments [b], lingual appliance [c], ceramic brackets [d], no appliance [e; control]) were shown to 140 participants. Eye movement and gaze direction was recorded by eye-tracking system. For different anatomical areas and areas of the appliances, time to first fixation and total fixation time were recorded. The questions included in a visual analog scale regarding individual sentiency were answered by the participants. Results For all groups, the anatomical landmarks were inspected in the following order: (1) eyes, (2) mouth, (3) nose, (4) hair, and (5) ears. Only in group d, first fixation was on the mouth region (1.10 ± 1.05 seconds). All appliances except the lingual appliance (1.87 ± 1.31 seconds) resulted in a longer fixation on the mouth area (a, 2.97 ± 1.32 seconds; b, 3.35 ± 1.38 seconds; d, 3.29 ± 1.36 seconds). For close-up pictures, the fastest (0.58 seconds) and longest (3.14 seconds) fixation was found for group d, followed by group b (1.02 seconds/2.3 seconds), group a (2.57 seconds/0.83 seconds), and group c (3.28 seconds/0.05 seconds). Visual analog scale scoring of questions on visibility were consistent with eye-tracking measurements. With increasing visibility, the feeling of esthetic impairment was considered higher. Conclusions Lingual orthodontic appliances do not change how the face is perceived. Other esthetic orthodontic appliances may change the pattern of facial inspection and are different in subjective perception.

Background: The benefits of interceptive orthodontic treatment have always been a subject of much debate, and it is understandable that clinicians are confused about how to advise parents of potential interceptive orthodontic patients. Objective: The aim is to study the treatment outcomes of interceptive orthodontics associated with different appliances. Demographic information on patients presenting for interceptive treatment, prevalence and types of dental conditions treated, types and frequency of appliances used, treatment duration and the number of visits taken were also investigated. Methods: This study involved analyzing records of interceptive orthodontic patients seen at the National Dental Centre Singapore from January 2011 to December 2017. Treatment outcomes were divided into success, improvement and failure according to pre-determined treatment objective parameters. Results: A total of 1324 patient records (654 females, 670 males) were studied, with an average age of 10.6±1.9 years. The most common dental condition seen was the anterior crossbite while the most common interceptive orthodontic appliance used was the bite plate. Average treatment duration was 10.8±6.8 months (9.8±9.2 visits) for fixed appliances, 7.5±6.5 months (6.9±3.4 visits) for removable appliances and 10.8±3.2 months (12.6±3.3 visits) for a combination. Interceptive orthodontic treatment had an overall success rate of 75.5%, improvement rate of 9.5% and failure rate of 15.0%. The most common reason for failure was attributed to non-compliance. Conclusion: The data above shed light on interceptive orthodontic treatment in an Asian population and gives useful information for primary care clinicians to provide for concerned parents.

Abstract Objective: To compare the periodontal status of adults treated with fixed buccal orthodontic appliances vs removable orthodontic aligners over 1 year of active therapy. Materials and Methods: The study population consisted of 42 subjects; 22 treated with fixed buccal orthodontic appliances and 20 treated with removable aligners. Clinical indices recorded included: plaque index (PI), gingival index (GI), bleeding on probing (BOP), and probing pocket depth (PPD). Plaque samples were assessed for hydrolysis of N-benzoyl-DL-arginine-naphthylamide (BANA test). Indices and BANA scores were recorded before treatment and at 6 weeks, 6 months, and 12 months after initiation of orthodontic therapy. Results: After 6 weeks, only mean PPD was greater in the fixed buccal orthodontic appliance group. However, after 6 months, the fixed buccal orthodontic appliance group had significantly greater mean PI, PPD, and GI scores and was 5.739 times more likely to have a higher BANA score. After 12 months, the fixed buccal orthodontic appliance group continued to have greater mean PI, GI, and PPD, while a trend was noted for higher BANA scores and BOP. Conclusions: These results suggest treatment with fixed buccal orthodontic appliances is associated with decreased periodontal status and increased levels of periodontopathic bacteria when compared to treatment with removable aligners over the 12-month study duration.

To evaluate the patient perception of orthodontic appliances and their experience during orthodontic treatment. Patient data archived in the institution’s database were reviewed and data pertaining to patients undergoing orthodontic treatment was retrieved. 60 patients were identified randomly. A questionnaire was framed to record the patient's compliance to functional appliance therapy. The questionnaire survey was framed and sent to the patient by sharing the link of the survey planet that consists of necessary context. Chi-square, fisher exact tests were used for data analysis through SPSS software. It was found that patients needed more time to the orthodontic appliance. 66% of patients had eating difficulties, 63.3%. More than half of the patients encountered oral sores almost 57.7%. 64% of the patients using these appliances encountered breakage and displacement problems. A total of 54% of patients stated that they had difficulty in keeping the appliances clean and maintaining proper oral hygiene Individuals undergoing orthodontic treatment had more difficulty to perform routine activities. Care must be taken to overcome these difficulties.

ABSTRACT Objective: To explore the impact of fixed labial orthodontic appliances on speech sound production. Materials and Methods: Speech evaluations were performed on 23 patients with fixed labial appliances. Evaluations were performed immediately prior to appliance insertion, immediately following insertion, and 1 and 2 months post insertion. Baseline dental/skeletal variables were correlated with the ability to accommodate the presence of the appliances. Results: Appliance effects were variable: 44% of the subjects were unaffected, 39% were temporarily affected but adapted within 2 months, and 17% of patients showed persistent sound errors at 2 months. Resolution of acquired sound errors was noted by 8 months post–appliance removal. Maladaptation to appliances was correlated to severity of malocclusion as determined by the Grainger’s Treatment Priority Index. Sibilant sounds, most notably /s/, were affected most often. Conclusions: (1) Insertion of fixed labial appliances has an effect on speech sound production. (2) Sibilant and stopped sounds are affected, with /s/ being affected most often. (3) Accommodation to fixed appliances depends on the severity of malocclusion.

Orthodontic appliances modify the local environment of the oral cavity, increase the accumulation of dental plaque, and affect the condition of the gingiva. The aim of this study is assessment of Brazilian propolis toothpaste’s effect on plaque index (PLI) and gingival index (GI) in patients with CL/CLP treated using orthodontic appliances in the 35-day study period. The study population included 96 patients of an Orthodontic Outpatient Clinic, ACSiMS in Bytom. All the patients participated in the active phase of orthodontic treatment using buccal multibracket appliances or removable appliances. During the first examination, each patient was randomly qualified to the propolis group or control group. A statistically significant decrease in GI and PLI in the entire propolis group (P<0.01) was shown during repeated examination. Insignificant change in GI was in the entire control group during the repeated examination compared to the baseline. Similar result was obtained in patients treated with multibracket and removable appliances. The orthodontic appliance type did not affect the final dental plaque amount and gingival condition in patients using the propolis toothpaste. These results may be clinically useful to improve prevention and control oral infectious diseases during orthodontic treatment patients with oral cleft.

Concern about allergic reactions in orthodontic patients has been expressed regularly. Patients undergoing orthodontic treatment with fixed appliances are exposed to various biomaterials. Awareness of reactions that can occur with these dental materials is important to the orthodontist. The aim of this paper is to review the current literature on allergy in orthodontics and the implications of the allergic reaction in the management of patients during orthodontic treatment. Diagnosis and treatment should include a multidisciplinary team. In all instances, the patient’s well-being should guide treatment decisions, and general health not just oral health should be the goal.

Objective: To compare young people’s experiences of wearing a range of orthodontic appliances. Design: A cross-sectional, qualitative study with purposive sampling. Setting: UK dental teaching hospital. Participants: Twenty-six orthodontic patients aged 11–17 years. Methods: Patients participated in in-depth semi-structured interviews. All interviews were transcribed verbatim and analysed thematically. Results: Young people reported physical, practical and emotional impacts from their appliances. Despite these reported impacts, participants described ‘getting used’ to and, therefore, not being bothered by their appliance. Framework analysis of the data identified a multi-dimensional social process of managing everyday life with an appliance. This involves addressing the ‘dys-appearance’ of the body through physically adapting to an appliance. This process also includes psychological approaches, drawing on social networks, developing strategies and situating experiences in a longer-term context. Engaging in this process allowed young people to address the physical, practical and emotional impacts of their appliances. Conclusion: This qualitative research has identified how young people manage everyday life with an appliance. Understanding this process will help orthodontists to support their patients.

Full textAbstract:
There has been tremendous progress in orthodontics since Edward Angle first popularised the fixed orthodontic appliance at the turn of the century. Recent years have seen an increased demand for orthodontic treatment from both adolescents and adults and, in addition, patient and clinician expectations of treatment outcomes continue to rise. A desire for more aesthetic materials has resulted in both smaller and ‘tooth-coloured’ appliances. Improvements in technology, often outside orthodontics, have also led to the development of new materials. The best example of this was the development of nickel titanium alloy by the NASA space programme, which was subsequently adapted for use in nickel titanium archwires. Other technological advances adopted for use in orthodontics include magnets, computerised imaging systems and distraction osteogenesis. This review paper looks at some of the innovations in the fields of materials as well as in techniques and appliance systems.

Background. Depending on the indication, and the age of a patient, class II division I malocclusion can be treated by a fixed or mobile orthodontic appliance, with or without teeth extraction. Case report. A treatment of a male patient, 15 years old, with dentoalveolar class II division I was described. On the base of clinical findings, study case analysis, analysis of orthopan and profile cephalogram, there were class II division I with protrusion of frontal teeth and mild crowding in lower jaw assessed. The patient was treated by fixed orthodontics appliances (SWA Roth .022") in both jaws for 18 months, with the retention period of the same length. Conclusion. Fixed ortodontic appliances are necessary when bodily movement of the teeth is indicated - in this case for cuspids distalization and retraction of incisors.

ABSTRACT Objective: The aim of this retrospective study was to evaluate the relationship between orthodontic treatment and gingival health. Materials and Methods: A total of 251 patients among whom 177 were girls and 74 were boys, recruited from the records pool of the Department of Orthodontics, Faculty of Dentistry, University of Gazi, were included in the study. Patients’ treatments have been completed by postgraduate students during the period between 2006 and 2012. Patients’ folders were analyzed according to their age, treatment time, and the type of orthodontic treatment. Intra-oral photographs were analyzed, and the presence or absence of visible plaque, visible inflammation, and gingival recession were recorded, and incisor inclinations analyzed on lateral cephalometric films, before and after orthodontic treatment. Results: No statistically significant difference was found in patients treated with functional appliances before and after treatment. In patients treated with fixed orthodontic appliances, visible plaque, visible inflammation, and gingival recession showed significant increases after treatment, gingival biotype did not show any significant difference. Positive correlation was found between lower incisor position and gingival recession in patients treated with fixed appliance and extraction. And also cuspids were the teeth with the highest prevalence of gingival recession. Conclusion: Considering the relationship between orthodontic treatment and gingival health, cooperation among patients, orthodontists, and periodontists is important.

Aims and Objectives: The high esthetic demands led to the promotion of various esthetic appliances like lingual orthodontics. This study aimed to review clinical outcome and potential complications of lingual orthodontics to achieve an evidence-based decision for orthodontic therapies. Materials and Methods: A comprehensive electronic search was conducted from January 1975 to March 2019 which was limited to English language and administrations of lingual orthodontics treatment which evaluated its efficacy and potential complications. Data extraction was performed according to the PRISMA statement. Results: 49 studies were selected and analyzed in this systematic review. The pain of lingual appliances starts a little earlier and lasts longer, and patients with lingual appliances experience more tongue discomfort and less cheek and lip pain and greater eating difficulties especially after placement and take a longer time to adapt to appliances. Lingual appliances generally cause more plaque accumulation and gingivitis especially in lingual anterior teeth; however, labial appliances are associated with high frequency in posterior maxillary teeth. Conclusion: This systematic review shows that despite the drawbacks of these appliances such as pain and eating difficulties, they can accomplish treatment goals with the same outcomes in comparison with conventional approaches, within the same duration and even lesser anchorage loss.

Abstract Objective: To evaluate the impact of psychological traits on patients' choice of orthodontic appliances and their adjustability to orthodontic treatment. Materials and Methods: The sample consisted of 68 adult patients divided into three groups (28 buccal, 19 lingual, and 21 clear aligners). Prior to treatment participants filled out the Brief Symptom Inventory to assess symptoms of mental distress and the Narcissistic Vulnerability Scale to assess narcissistic personality traits. During the first week after appliance delivery and on day 14, patients completed a Health-Related Quality of Life questionnaire to assess their perception of pain and four areas of dysfunction. The correlation between personality traits and patients' reaction to treatment was evaluated. Results: Somatization was the only trait that affected the choice of lingual and clear aligner appliance. Reduced self-esteem regulation was associated with increased pain in all patients, while exploitation was associated with pain in lingual patients. Narcissistic vulnerability slightly influenced patients' adaptability to orthodontic appliances. Although adjustability to lingual appliances was the most difficult, only two parameters were affected by personality features. In the buccal group, adjustability was affected by numerous parameters. Adaptation to the clear aligner appliance was relatively uneventful and least affected by psychological features. Conclusion: Anxious individuals tend to prefer lingual and clear aligner appliances. The selection of lingual and clear aligner appliances governs the patient's response and recovery process, leaving little room for the effect of psychological features. On the other hand, the buccal appliance allows for greater impact of personality traits on adjustability.

Treatment of complex malocclusion poses a challenge for the orthodontist because of its multifactorial aetiology. Class II malocclusion is the most frequently encountered and treated malocclusion in orthodontic practice and affects approximately 14.6 % of the North Indian population.1 A common reason for Class II malocclusion is mandibular skeletal retrusion which is the most common characteristic, as reported by McNamara.2 This can be caused by genetic or hereditary factors. When evaluating treatment options for Class II patients, the extent of the skeletal discrepancy and the skeletal maturity of the patient needs to be considered. Treatment may range from dental compensation including camouflage with extractions to surgical procedures targeted at moving the jaw at fault. In growing patients, growth modification with functional appliances offers an intermediate treatment option. Functional appliances are basically of two types; Removable and Fixed. Removable functional appliances such as Activator, Bionator, Frankel Function regulator and Twin Block appliance change Class II relationship by the transmission of soft tissue tension to the dentition. Treatment success with these appliances relies heavily on patient compliance. Therefore, in non-compliant patients, fixed Class II correctors in conjunction with fixed orthodontic appliances are the best choice.3 Fixed functional appliances generate continuous stimuli for mandibular growth without break and permit better adaptation to functions like mastication, swallowing, speech and respiration.1 The Herbst fixed functional appliance has been used routinely for Class II patients and has undergone many design variations over time.4 The AdvanSync2 Class II corrector is a recently introduced fixed functional appliance. It has a much smaller size than the conventional Herbst appliances, is easier to place, activate and remove and most importantly, can be used in conjunction with full-arch fixed appliances throughout.3 Here we describe a case report of a patient treated with the AdvanSync2 Class II corrector and the findings observed in the sagittal and vertical dimensions

OBJECTIVE: To evaluate the esthetic perception of different appliances by Brazilian lay adults and its influence in the attributed value of orthodontic treatment, considering evaluators' socioeconomic status, age and gender. METHODS: Eight different combinations of orthodontic appliances and clear tray aligners were placed in a consenting adult with pleasing smile. Standardized frontal photographs were captured and incorporated into a research album. A sample of adults (n = 252, median = 26 years old) were asked to rate each image for (1) its attractiveness on a visual analog scale and (2) the willingness to pay (WTP) for a cosmetic appliance when compared to a standard metalic appliance and a clear tray aligner. Comparisons between the appliances' attractiveness were performed using the Friedman's test and Dann's post-hoc test. Correlation between appliances' attributed value, socioeconomic status, age, gender, and esthetic perception was assessed using Spearman's correlation analysis. RESULTS: Attractiveness ratings of orthodontic appliances varied significantly in the following hierarchy: Clear aligners>sapphire brackets>self-ligating/conventional stainless steel brackets>and golden metal appliances. The correlation between WTP and esthetic perception was week. However, for individuals with better socioeconomic status and aged between 17-26 years old significantly, a significantly higher WTP was found. CONCLUSION: Clear aligners and sapphire brackets with esthetic archwire were considered better esthetic options in this sample. Nevertheless, patients were not willing to pay more money for appliances they deemed more esthetic, however, they were significantly influenced by their socioeconomic level and age.

While uncommon in orthodontics, the extraction of central incisors may be indicated when such teeth are of poor prognosis. This report details orthodontic treatment of a 13-year and 5-month-old Chinese female, who presented with Class II/1 malocclusion on a Class II skeletal jaw base relationship. Her maxillary central incisors were ankylosed and had undergone severe external root resorption following a previous traumatic episode. Orthodontic treatment involved removal of the maxillary central incisors and the mandibular first premolars. Pre-adjusted edgewise appliances with MBT prescription were used. To enhance anterior esthetics, prosthetic buildup of the four maxillary anterior teeth was performed before appliance removal. Tight intercuspation of teeth and optimal facial esthetics were achieved at appliance debond and maintained at 2-year follow-up.

ABSTRACT Introduction Malocclusion plays an important role in the development of periodontitis. Thus, by treating malocclusion, a good gingival health can be achieved. This study was conducted to establish the correlation between orthodontic tooth movement and periodontitis. Materials and methods This is a retrospective study conducted on 220 patients who underwent orthodontic treatment for malocclusion. They were divided into two groups: Group I patients were treated with fixed orthodontics, while group II patients received myofunctional appliances. Results The value for plaque, gingival recession, and tooth mobility significantly increased in group I patients. However, the difference was statistically nonsignificant in group II patients. Conclusion The authors concluded that there is correlation between malocclusion and periodontitis. Malocclusion leads to periodontitis. Clinical significance Malocclusion is the main reason for the development of poor periodontal health. Combined effort has to be played by both periodontist and orthodontist for the treatment of various orthodontic-periodontal problems.

Full textAbstract:
Magnetic resonance imaging (MRI) is a widely used diagnostic technique. Patients wearing orthodontic appliances are often requested to remove their appliances, even when the MRI exam involves anatomical areas far from mouth, in order to avoid heating of the metal and detachment of the appliance. The purpose of the present investigation was to measure and compare temperature changes and orthodontic appliances’ adhesion to enamel after different MRIs. A total of 220 orthodontic brackets were bonded on bovine incisors and wires with different materials (stainless steel and nickel titanium). Moreover, various sizes (0.014″ and 0.019″ × 0.025″) were engaged. Appliances were submitted to MRI at two different powers (1.5 T and 3 T). The temperatures of brackets and wires were measured before and after MRI. Subsequently, the shear bond strength (SBS) and adhesive remnant index (ARI) scores were recorded. Statistical analysis was performed. After MRI, a significant increase in the temperature was found for both the brackets and wires in some groups, even if the mean temperature increase was clinically insignificant, as the temperature ranged between 0.05 °C and 2.4 °C for brackets and between 0.42 °C and 1.74 °C for wires. The MRI did not condition bracket adhesion in any group. No differences were reported when comparing the 1.5 T with 3 T groups. The ARI Scores were also significantly lower after MRI. The results of the present report show that, under MRI, orthodontic appliances present a low temperature rise and no debonding risk. Therefore, the removal of orthodontic appliance is not recommended routinely, but is suggested only in the case of a void risk or potential interference in image quality.

In modern orthodontics, aesthetics appear to have a decisive influence on orthodontic appliance preferences and acceptability. This paper reports the early application of a newly emerged functional device with enhanced aesthetics in a Class II treatment. Patient perspectives and technical considerations are discussed along with recommendations for further design development. It can be assumed that the use of thermoplastic material-based appliances may meet both the therapeutic and aesthetic demands of young age groups.

Full textAbstract:
Mandibular incisor extraction for orthodontic treatment is considered an unusual treatment option because of the limited number of patients that meet the criteria for such treatment. Accurate diagnosis and treatment planning is essential to achieve the desired results. Adult orthodontic patients are increasingly motivated by esthetic considerations and reject the idea of conventional fixed appliances. In recent years, Invisalign appliances have gained tremendous attention for orthodontic treatment of adult patients to meet their esthetic demands. In this case report, a case of Class I malocclusion was treated with mandibular incisor extraction using the Invisalign appliance system. Successful tooth alignment of both arches was achieved. The use of Invisalign appliance is an effective treatment option in adult patients with Class I malocclusion that requires incisor extraction due to moderate to severe mandibular anterior crowding.

Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of problems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite correction in young children is treatment compliance. In most cases, poor compliance is due to the unacceptability of the removable appliance used. This article describes three cases of successful correction of anterior crossbite of patients in mixed dentition using short-span wire-fixed orthodontic appliances. This sectional appliance provides an alternative method of correcting anterior crossbite of dental origin and offers many advantages compared to the use of removable appliances.

The purpose of the study was to increase the effectiveness of orthopedic and orthodontic treatment of children with dentition defects during the period of mixed occlusion to prevent secondary dento-maxillaire deformities. Material and methods. 47 patients aged from 6 to 11 years with dentition defects in the frontal and lateral areas were examined and treated to conduct comparative evaluation of the effectiveness of using removable and non-removable prostheses appliances in patients with dentition defects during the period of mixed occlusion. All the patients were divided into two clinical groups by the design type of a prosthesis appliance, the choice of which depended on the results of a complete clinical research taking into account the location and the length of dentition defects. For group I patients (n=29), we used removable orthodontic prostheses appliances (standard mechanically-operated appliances with artificial teeth), in areas with missing teeth, to regulate the size of upper and lower dentition and replace dentition defects. For group II patients (n=18), we used non-removable orthodontic prostheses appliances (bands with a spacer and a non-removable prosthesis appliance of our own design). At the beginning of treatment and after 3 and 6 months, the assessment of oral hygiene was conducted using Yu. A. Fedorov and V. V. Volodkina indices. Follow-up examinations of patients in both groups were conducted once a month. However, every 3 and 6 months, patients of group I (with removable prosthesis appliances) received repetitive jaw impressions and made control diagnostic models, which measured the size of a dentition defect area to monitor the treatment. The data on control measurements was compared with data obtained at the beginning of the treatment. The criteria for completion of orthodontic treatment were considered to be the regulation of the size of upper and lower dentition and the position of individual teeth, as well as the preservation of the place in the dental arch until the physiological change of prematurely lost teeth. Results and discussion. The main causes of dentition defects occurrence in patients of both groups were the following: premature removal of temporary and permanent teeth due to complications of caries – 39 patients (83.0%), the loss of teeth due to a trauma – 5 patients (10.5%). Dentition defect was caused by adentia – in 2 people (4.3%), by retention – in 1 person (2.1%). We determined that 30 people (63.8%) had defects of the upper jaw, which was the most prevailing dentition defects. Dentition defects in the lateral areas were recorded in 32 people (68.1%). The largest number of dentition defects was of short size – 29 (61.7%). To restore the integrity of the dentition, we made 29 removable prostheses appliances with artificial teeth for group I patients, 9 (31.0%) of them served to replace dentition defects of the frontal area and 20 (69.0%) replaces dentition defects of the lateral area. In order to replace the dentition defect and preserve the place in the dental arch, we made 18 non-removable prostheses appliances for group II patients, 6 (33.3%) of them were of our own design to replace the dentition defect in the frontal area, and 12 (66.7%) replaced teeth gap bands with a spacer for the lateral one. Based on the analysis of these indicators in people with dentition defects who used removable and non-removable appliances, we can conclude, that there is a clear connection between the impact of orthodontic appliances on oral hygiene, depending on its type. The negative dynamics of changes in the hygiene index according to Fedorov-Volodkina in patients with non-removable prostheses appliances can be explained by the deterioration of oral hygiene conditions due to the design features of the appliances and the inability to remove the appliance yourself. Therefore, the use of non-removable appliances requires additional hygienic measures. Removable appliances had almost no effect on the state of oral hygiene, but worked less predictably by reducing the time of their active action in the oral cavity. If children refused to wear removable prostheses and prosthesis appliances, there quickly developed secondary dento-maxillaire deformities, which over time became more stable, and pathological changes were more significant. In group I patients, 6 months after the start of treatment with removable prostheses appliances, the shortening of dentition defects was detected in the frontal area by 1.3±1.1 mm and in the lateral area by 1.2±0.9 mm. Negative changes in the length of the dentition defect in patients of group I before treatment and after 6 months are specifically connected with irresponsible attitude to treatment. Not all patients in this group fully wore removable prostheses appliances, and some of them did not wear at all. Conclusion. Our research showed that removable orthodontic appliances for replacement of dentition defects and prevention of secondary dento-maxillaire deformities could be used in patients of different ages, their special effectiveness was observed in pediatric-age patients, however, only in those who responsibly followed the recommendations of an orthodontist. The use of non-removable orthodontic appliances for replacement of dentition defects and prevention of secondary dento-maxillaire deformities is a more rational choice of dental prosthesis. The prosthesis appliance for the upper jaw developed by us doesn’t inhibit the growth of the jaw, meets all the esthetic and functional requirements applied to these appliances. During treatment with non-removable appliances patients cannot control the time when the appliance “works”, which leads to a more predictable result of treatment

Background (1): Removable orthodontic appliances may favor plaque accumulation and oral microbe colonization. This might be associated with intraoral adverse effects on enamel or periodontal tissues. The proposed systematic review was carried out to evaluate qualitatively and quantitatively the microbiological changes occurring during orthodontic therapy with removable orthodontic appliances. Methods (2): PubMed, Cochrane Library, Embase, Web of Science, Scopus, Ovid Medline, and Dentistry and Oral Sciences Source were searched. The research included every article published up to January 2020. The Preferred Reporting Items for Reporting Systematic reviews and Meta Analyses (PRISMA) protocol and the “Swedish Council on Technology Assessment in Health Care Criteria for Grading Assessed Studies” (SBU) method were adopted to conduct this systematic review. Results (3): The current study has a moderate evidence, demonstrating that removable appliances do influence the oral microbiota. Significant alterations occur just 15 days after the beginning of therapy, independently from the type of appliance. Furthermore, the levels of oral pathogens decrease significantly or even returned to pre-treatment levels several months later the therapy end. Conclusions (4): This review suggests that orthodontic treatment with removable appliances induces changes to oral microflora, but these alterations might not be permanent.

Kombinasi alat semi-cekat pada rahang bawah dan alat ortodontik lepasan pada rahang atas efektif untuk koreksi maloklusi Angle Klas II divisi 1 dengan kehilangan gigi 46 pada pasien ini. ABSTRACT: Orthodontic Treatment Using Semi-Fixed Appliances with Partial Edentulous 46. Cost is one of the considerations in determining the use of orthodontic appliances. Removable orthodontic appliance is chosen because it is less costly than fixed orthodontic appliances. It is difficult to use removable orthodontic appliances to treat a missing one or more posterior teeth case. A 23 year old female patient had a chief complaint of crowding in lower anterior teeth and forwardly placed upper anterior teeth. Her objective examination shows protrution of upper teeth, crowding in the lower arch, palatal bite, and partial edentulous of 46 tooth. It was Angle Class II division 1 dentoskeletal malocclusion, skeletal class II, bimaxillary protrusion, bidental protrusion, overjet 7,2 mm, crowding, palatal bite, and mouth-breathing habit. The treatment used a combination of semi-fixed orthodontic appliances in the lower arch and removable appliances in the upper arch. The semi-fixed orthodontic appliances were used on space closing of partial edentulous 46. The partial edentulous 46 was closed after 6 months of treatment. The overjet was reduced to 4 mm and overbite 2,7 mm after one year of treatment. The combination of semi-fixed orthodontic appliances in the lower arch and removable appliances in the upper arch generate a good result to correct Angle Class II division 1 malocclusion with partial edentulous 46.

Poor oral hygiene has been considered one of the main problems routinely faced in the orthodontic treatment. Orthodontic appliance creates an environment that provides mineral loss from the dental enamel. Such condition is clinically seen as white spot lesions and cavitations in the most severe cases. The aim of this study was to evaluate the effects of a fluoride varnish application as a caries prevention method for clinical orthodontics. The experiment analyzed dental enamel adjacent to orthodontics accessories after treatment. In addition, it was observed the calcium, phosphorus and fluoride contents on enamel treated with a fluoride varnish. The results showed that fluoride varnish application is a simple and fast technique that could be useful in preventing enamel demineralization associated to orthodontic treatment. Scanning electron microscopy revealed significant amount of calcium fluoride-like material deposited on enamel and energy dispersive x-ray analysis demonstrated a large incorporation of calcium and fluoride to the enamel of the treated specimens. It was concluded that fluoride varnish could indeed be considered an efficient preventive method to enhance enamel resistance against the cariogenic challenges during orthodontic therapy.

Relevance. The present article provides data regarding changes in the oral cavity during orthodontic tratment with custom-made removable appliances. Purpose. To study the condition of the oral cavity in children aged 7-12 with dentoalveolar abnormalities during treatment with removable orthodontic appliances.Materials and methods. 110 patients aged 7-12 were examined in Nakhodka, Russia. Group I – control (34 subjects) with no dentoalveolar pathology. Group II – children with dentoalveolar pathology (74 subjects), undergoing orthodontic treatment. Besides clinical examination the following laboratory tests were taken, namely: saliva viscosity, saliva PH, saliva buffer capacity, microcrystallography of saliva. Type III prevailed in 60% of cases. Results. Caries intensity during orthodontic treatment was detected to increase up to 8.32 ± 0.28 in comparison with control group 6.57 ± 0.22 (p < 0.05). Hygiene rate decreased in experimental group to 2.8 ± 0.08, in comparison with controls – 1.40 ± 0.02 (p < 0.05). Salivary PH decreased during orthodontic treatment. Microcrystallization type III of saliva prevailed in 60% of cases.Conclusions. The study revealed strong relationship between orthodonotic treatment with removable appliances and physicochemical properties of mixed saliva r = 0.95 (p < 0.05). Appropriate approach and timely preventive measures can help correct oral condition in orthodontic treatment. Despite changes in oral fluid composition, esthetic and functional result of treatment with orthodontic customized removable appliances was high.

ABSTRACT Objective: The objective of this present study was to understand how children and adolescents perceive esthetic attractiveness of a variety of orthodontic appliances. It also analyzed preferences according to patients' age, sex and socioeconomic status. Methods: A photograph album consisting of eight photographs of different orthodontic appliances and clear tray aligners placed in a consenting adult with pleasing smile was used. A sample of children or adolescents aged between 8 and 17 years old (n = 276) was asked to rate each image for its attractiveness on a visual analog scale. Comparisons between the appliances attractiveness were performed by means of nonparametric statistics with Friedman's test followed by Dunn's multiple comparison post-hoc test. Correlation between appliances and individuals' socioeconomic status, age, sex, and esthetic perception was assessed by means of Spearman's correlation analysis. Results: Attractiveness ratings of orthodontic appliances varied nonsignificantly for children in the following hierarchy: traditional metallic brackets with green elastomeric ligatures > traditional metallic brackets with gray elastomeric ligatures > sapphire esthetic brackets; and for adolescents, as follows: sapphire esthetic brackets > clear aligner without attachments > traditional metallic brackets with green elastomeric ligatures. The correlation between individuals' socioeconomic status and esthetic perception of a given appliance was negative and statistically significant for appliances such as the golden orthodontic brackets and traditional metallic brackets with green elastomeric ligatures. Conclusion: Metal appliances were considered very attractive, whereas aligners were classified as less attractive by children and adolescents. The correlation between esthetic perception and socioeconomic status revealed that individuals with a higher socioeconomic level judged esthetics as the most attractive attribute. For those with higher economic status, golden orthodontic brackets and traditional metallic brackets with green elastomeric ligatures were assessed as the worst esthetic option.

ABSTRACT Objective: The aim of this prospective study was to compare the periodontal health and the microbiological changes via real-time polymerase chain reaction (PCR) in patients treated with fixed orthodontic appliances and Invisalign® system (Align Technology, Santa Clara, California). Materials and Methods: Seventy-seven patients were enrolled in this study and divided into three groups (Invisalign® group, fixed orthodontic appliances group and control group). Plaque index, probing depth, bleeding on probing were assessed. Total biofilm mass and periodontal pathogens were analyzed and detected via real-time PCR. All these data were analyzed at the T0 (beginning of the treatment) T1 (1-month) and T2 (3 months); and statistically compared using the Mann–Whitney test for independent groups. Results: After 1-month and after 3 months of treatment there was only one sample with periodontopathic anaerobes found in patient treated using fixed orthodontic appliances. The Invisalign® group showed better results in terms of periodontal health and total biofilm mass compared to the fixed orthodontic appliance group. A statistical significant difference (P < 0.05) at the T2 in the total biofilm mass was found between the two groups. Conclusion: Patients undergoing orthodontic treatment with the Invisalign® System show a superior periodontal health in the short-term when compared to patients in treatment with fixed orthodontic appliances.

Full textAbstract:
This paper discusses the issues of strength and creep of polymeric materials used in orthodontic appliances. Orthodontic biomechanics is focused on the movement of individual teeth or dental groups as a result of the force applied by orthodontic appliances. Stresses in the construction of functional and biomechanical appliances is generated when using the apparatus in the oral cavity. The orthodontic appliance must maintain its shape and not be damaged during treatment so strength and creep resistance are fundamental properties. It was assumed that the clinical success of orthodontic appliances can be determined by these performance properties. The aim of the work was the experimental assessment of comparative bending strength and creep resistance of selected popular polymer materials used in the production of biomechanical orthodontic appliances. Four commercial materials manufactured by the world class producers were tested: NextDent Ortho Rigid (Vertex-Dental B.V., Soesterberg, The Netherlands) marked as “1A”; Erkocryl (ERKODENT Erich Kopp GmbH, Pfalzgrafenweiler, Germany)-“2A”; Vertex Orthoplast (Vertex Dental B.V.), blue, marked as “3A” and material with the same name as “3A” but orange, marked in the article as “4A”. All the tests were carried out after aging in artificial saliva for 48 h at a temperature of 37 °C. Flexular strength and flexular modulus were made using the three point bending method according to the ISO 178 technical standard. Creep tests were carried out according to the method contained in ISO 899-2. The creep test was carried out in an artificial saliva bath at 37 °C. The creep tests showed significant differences in the strength, modulus and deformability of the tested materials. The strength reliability of the tested materials also varied. The research shows that the 2A material can be used for orthodontic applications in which long-term stresses should be lower than 20 MPa.

Full textAbstract:
The success of removable orthodontic appliance mainly depends upon good retention of the appliance. Adequate retention of a removable orthodontic appliance is achieved by incorporating certain wire components, called clasp, which engages the undercuts on the teeth. Clasps are the retentive components of removable orthodontic appliances. There are various designs of clasps advocated for various clinical situations. This article presents an overview of various clasp designs with advantages and disadvantages of each type and their uses in particular clinical situations.

Full textAbstract:
Nanotechnology has gained importance in recent years due to its ability to enhance material properties, including antimicrobial characteristics. Nanotechnology is applicable in various aspects of orthodontics. This scientific work focuses on the concept of nanotechnology and its applications in the field of orthodontics, including, among others, enhancement of antimicrobial characteristics of orthodontic resins, leading to reduction of enamel demineralization or control of friction force during orthodontic movement. The latter one enables effective orthodontic treatment while using less force. Emphasis is put on antimicrobial and mechanical characteristics of nanomaterials during orthodontic treatment. The manuscript sums up the current knowledge about nanomaterials’ influence on orthodontic appliances.

Full textAbstract:
ABSTRACT Objective: To investigate the impact of wearing a fixed orthodontic appliance on oral health-related quality of life (OHRQoL) among adolescents. Materials and Methods: A case-control study (1∶2) was carried out with a population-based randomized sample of 327 adolescents aged 11 to 14 years enrolled at public and private schools in the City of Brumadinho, southeast of Brazil. The case group (n = 109) was made up of adolescents with a high negative impact on OHRQoL, and the control group (n = 218) was made up of adolescents with a low negative impact. The outcome variable was the impact on OHRQoL measured by the Brazilian version of the Child Perceptions Questionnaire (CPQ11–14) – Impact Short Form (ISF:16). The main independent variable was wearing fixed orthodontic appliances. Malocclusion and the type of school were identified as possible confounding variables. Bivariate and multiple conditional logistic regressions were employed in the statistical analysis. Results: A multiple conditional logistic regression model demonstrated that adolescents wearing fixed orthodontic appliances had a 4.88-fold greater chance of presenting high negative impact on OHRQoL (95% CI: 2.93–8.13; P < .001) than those who did not wear fixed orthodontic appliances. A bivariate conditional logistic regression demonstrated that malocclusion was significantly associated with OHRQoL (P = .017), whereas no statistically significant association was found between the type of school and OHRQoL (P = .108). Conclusions: Adolescents who wore fixed orthodontic appliances had a greater chance of reporting a negative impact on OHRQoL than those who did not wear such appliances.

Full textAbstract:
Abstract Objective: To compare the postretention dental changes between patients treated with Invisalign and those treated with conventional fixed appliances. Materials and Methods: This is a comparative cohort study using patient records of one orthodontist in New York City. Two groups of patients were identified that differed only in the method of treatment (Invisalign and Braces group). Dental casts and panoramic radiographs were collected and analyzed using the objective grading system (OGS) of the American Board of Orthodontics (ABO). The cases were evaluated immediately after appliance removal (T1) and at a postretention time (T2), three years after appliance removal. All patients had completed active orthodontic treatment and had undergone at least one year of retention. A Wilcoxon rank sum test was used to evaluate differences in treatment outcomes between the groups for each of the eight categories in the OGS, including four additional subcategories in the alignment category. A Wilcoxon signed rank test was used to determine the significance of changes within each group from T1 to T2. Results: The change in the total alignment score in the Invisalign group was significantly larger than that for the Braces group. There were significant changes in total alignment and mandibular anterior alignment in both groups. There were significant changes in maxillary anterior alignment in the Invisalign group only. Conclusions: In this sample for this period of observation, patients treated with Invisalign relapsed more than those treated with conventional fixed appliances.

Full textAbstract:
The study maps out orthodontic care in Finnish municipal health centres in 2001, describes changes during the previous ten years reported by chief dental officers, and assesses the views of orthodontists on current public orthodontic services. The data were collected by questionnaires sent to all health centres and all orthodontists in Finland. Of all 0–18-year-olds, 11% were receiving orthodontic treatment with an appliance (range 2–43% among the health centres). The most frequently used appliances were headgear, quadhelix, and fixed appliances. Limited economic resources and the lack of orthodontic expertise were mentioned by the chief dental officers as factors decreasing the volume of services. The orthodontists mentioned the large regional variation and the lack of national guidelines as the most important aspects that should be improved on a national basis. To bring about improvement, they suggested increasing the number of specialist orthodontists and the delegation of orthodontic tasks to auxiliaries.

Objective The patient with bilateral cleft lip and palate and an edentulous premaxilla poses several additional challenges to the surgeon and the orthodontist. The cleft segments are usually expanded and stabilized with tooth-supported orthodontic appliances prior to an alveolar bone graft. This report describes a technique for stabilizing an edentulous premaxilla using an orthodontic-surgical screw that is ligated to an orthodontic archwire.

Full textAbstract:
Current status of clinical orthodontics in European and American countries was examined by means of a questionnaire survey through internet. In the European and American countries, most popular technique in daily orthodontic practice is preadjusted straight wire edgewise technique. In major developed countries in Europe and America, the treatment fee is considerably high, whereas the fee is relatively low in the countries under development and/or after economic crisis. Rate of non-extraction treatment among all the cases treated with multi-bracket appliances is significantly higher in Europe and America than in Asia except in a few countries. In the European and American countries, treatment system for jaw deformity patients is well developed with higher availability of the social health insurance than in Asia. The maximum CLP prevalence of 0.200 is found in Germany and Austria and the mean is around 0.140 or one to 700 births. In general, CLP treatment is covered by social health insurance in European and American countries. In Europe and America, lingual orthodontic technique has not become popular because patients never want to hide orthodontic appliance. Higher cost of lingual appliance and lack in information and technical skills may be the reasons of less frequent use of lingual appliance. Many interviewees replied that usage of TADs has not become so popular in USA and Canada as compared to that in Asia. In another word, the initial fascination with TADs wore off and are now used in selected patients as needed. This may be due to more harmonious maxillofacial structure with longer and wider dentitions in Caucasians which also results in higher rate of non-extraction treatment with multibracket appliances in European and American countries.
