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.

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: 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.

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.

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

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.

Abstract The aim of the study was to demonstrate the orthodontic treatment of malocclusions in dogs, a condition which can lead to cranio-mandibular and functional disorders of the stomatognathic system. The treatment involved the use of maxillofacialorthopaedic appliances, which type depended on the type of disorder and the degree of malocclusion. The applied treatment induced changes in the alveolar bone. Throughout the process of the treatment a great attention was paid to regular brushing off the orthodontic appliance using antiseptics for prophylactic prevention of inflammation of gingival tissue and the palate caused by food getting stuck in the spaces between the teeth.

Full textAbstract:
Skeletal Class III malocclusion, with its unpredictable and unfavorable nature, has been characterized by a growth pattern with doubtful prognosis regarding orthodontic mechanics, even when performed early. For a long time, Class III malocclusion was regarded as a synonym of mandibular prognathism, regardless of the affected skeletal structures. Mandibular growth, essentially determined by genetic factors, could barely be controlled by early orthodontic interventions. Therefore, the treatment choice was to wait for the patient to grow, and then make an orthodontic intervention associated with an orthognathic surgery. Maxillary involvement in the etiology of Class III malocclusion was conclusive to change orthodontic therapeutics. Maxillary intramembranous growth has a better response to orthopedic treatment, based on growth control and redirection, thus contributing for early intervention success. In several cases, excellent results have been achieved with rapid maxillary expansion and protraction. The aim of this study was to describe and discuss the treatment of a patient with Class III malocclusion, whose treatment planning comprised two phases: interceptive (mechanical orthopedic appliances) and comprehensive (fixed orthodontic appliance). The results of this case showed that Class III malocclusion should be intercepted as early as possible to permit growth redirection, mainly when the maxilla is the primary etiologic factor or dental and/or functional factors are involved. Diagnosis, treatment planning and prognosis depend on patient age, growth potential and severity of malocclusion. Early intervention, adequate indication of appliances, and patient compliance are key factors for good outcomes.

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 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.

Early Class III malocclusion treatment may not have long-term stability due to mandibular growth. Although some features of this malocclusion point to a better prognosis, it is practically impossible for the orthodontist to foresee cases that require new intervention. Many patients need retreatment, whether compensatory or orthodontic-surgical. The present study reports the case of a Class III patient treated at the end of the mixed dentition with the use of a face mask followed by conventional fixed appliances. The case remains stable 10 years after treatment completion. It was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as a requirement for the title of certified by the BBO.

ABSTRACT Objective: To investigate the masticatory and swallowing performances in patients with malocclusions before and after orthodontic treatment, comparing them to an age- and gender-matched control group with normal occlusion. Methods: Twenty-three patients with malocclusions requiring orthodontic treatment were included in this prospective study. One month after appliance removal, seventeen patients completed a follow-up examination and the data were compared with those of a control group with thirty subjects with normal occlusion. Masticatory performance was determined by the median particle size for the Optocal Plus® test food after 15 chewing strokes, and three variables related to swallowing were assessed: a) time and b) number of strokes needed to prepare the test-food for swallowing, and c) median particle size of the crushed particles at the moment of swallowing. Results: At the baseline examination, the malocclusion group had a significantly lower masticatory performance and did not reach the particle size reduction at the moment of swallowing, when compared with the control group. After treatment, the masticatory performance significantly improved in the malocclusion group and the particle size reduction at swallowing reached the same level as in the control group. Conclusions: The present results showed that the correction of malocclusions with fixed appliances can objectively provide positive effects in both mastication and deglutition processes, reinforcing that besides aesthetic reasons, there are also functional indications for orthodontic treatment.

Since Class III malocclusion is progressive in nature, the facial growth of Class III malocclusion worsens with age. Class III malocclusion is associated with a deviation in the sagittal relationship of the maxilla and the mandible, characterized by a deficient maxilla, retrognathic mandible, or a combination of both. The early orthopedic treatment of Class III malocclusions, at the end of primary dentition or the beginning of mixed dentition, prior to growth spurt, allows the accomplishment of successful results, providing facial balance, modifying the maxillofacial growth and development, and in many instances, preventing a future surgical treatment by increasing the stability. Many treatment approaches can be found in the literature regarding orthopedic and orthodontic treatment of Class III malocclusion, including intra- and extra-oral appliances. The major problem with extraoral anchorage has been of patient compliance due to its physical appearance. The case report presents an intraoral modified tandem appliance for maxillary protraction that has been used clinically to achieve successful results without relying much on patient co-operation.

The developing class III malocclusion is one of the most challenging problems for the practicing orthodontist to manage clinically. True class III malocclusion is rare in our region as compared to Class II and Class I malocclusion. With adults, orthognathic surgery and dental camouflage is the viable treatment option. A variety of treatment alternatives exists for patients in the developing stages of a Class III malocclusion. In the past much of the therapy has focused on restriction of mandibular growth with chin cups and functional appliances. This is based on the traditional thought that developing Class III malocclusions were the result of prognathic mandible. Recently, however, there has been a growing awareness that the majority of patients with a developing Class III skeletal pattern exhibit a maxillary deficiency with a normal or only slightly prognathic mandible. Therefore, considerable attention has been given to early treatment using maxillary protraction therapy. Using facemask therapy in conjunction with maxillary expansion has been shown in clinical reports to be a successful and predictable treatment option. Treatment should be carried out as early as possible with the aim to prevent it from becoming severe. A case treated with biphasic therapy – orthopaedic appliance followed by fixed orthodontic treatment is presented here.

Salah satu pertimbangan dalam menentukan alat ortodontik yang akan digunakan adalah biaya. Alat ortodontik lepasan dipilih karena memerlukan biaya yang lebih rendah dibanding dengan alat ortodontik cekat. Perawatan ortodontik dengan alat lepasan sulit dilakukan jika disertai dengan pencabutan satu atau beberapa gigi posterior. Pasien perempuan usia 23 tahun, mengeluhkan gigi rahang atas maju dan gigi rahang bawah berjejal. Pemeriksaan objektif menunjukkan protrusif rahang atas, crowding rahang bawah, palatal bite, disertai kehilangan gigi 46. Maloklusi Angle Kelas II divisi 1 tipe dentoskeletal, hubungan skeletal klas II, protrusif bimaksilar, bidental protrusif, overjet 7,2 mm, crowding, palatal bite, dan kebiasaan bernafas melalui mulut. Perawatan menggunakan kombinasi alat semi-cekat pada rahang bawah dan alat lepasan pada rahang atas. Alat semi-cekat digunakan untuk space clossing bekas pencabutan gigi 46. Terjadi space closing bekas pencabutan gigi 46 setelah 6 bulan perawatan. Overjet berkurang menjadi 4 mm dan overbite 2,7 mm setelah 1 tahun perawatan. 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.

ABSTRACT Treatment of class II malocclusion has always been an enigma to the orthodontic fraternity. Noncompliant correction of class II malocclusion using fixed functional appliances at the deceleration stage of growth has gained tremendous popularity in the recent times. Aim of the illustrated article is to demonstrate the efficacy of a fixed functional appliance in correction of class II malocclusion. We are reporting a 12-year-old female patient with a skeletal class II malocclusion treated using the Forsus appliance. Forsus FRD was the best option considering age, patient comfort, ease of installation, predictable results and patient compliance. The appliance was worn for 5 months after the initial alignment with fixed mechanotherapy (MBT 0.022"). The mandible was brought forward to a class I skeletal and dental relationship by the end of this phase of treatment.

Lingually displaced canine teeth is a common malocclusion condition in dogs, the treatment of which has been described 1,2,3,4,5. Several of the previously reported treatment regimens involve the use of potentially harmful (toxic and/or dangerously exothermic) substances (methylmethacrylate) or require separate anesthetic episodes to make impressions and place the appliance. In this case, a dog was treated with directly placed appliances made of non-heat generating light-cured resin. Treatment required only one anesthetic episode to place the appliances and one more to remove them.

Introduction. The effects of orthodontic treatment are considered to be successful if the facial harmony is achieved, while the structures of soft tissue profile are in harmony with skeletal structures of neurocranium and viscerocranium. In patients with skeletal distal bite caused by mandibular retrognathism, facial esthetics is disturbed often, in terms of pronounced convexity of the profile and change in the position and relationship of the lips. Objective. The aim of this study was to determine the extent of soft tissue profile changes in patients with skeletal Class II malocclusion treated with three different orthodontic appliances: Fr?nkel functional regulator type I (FR-I), Balters? Bionator type I and Hotz appliance. Methods. The study included 60 patients diagnosed with skeletal Class II malocclusion caused by mandibular retrognathism, in the period of early mixed dentition. Each subgroup of 20 patients was treated with a variety of orthodontic appliances. On the lateral cephalogram, before and after treatment, the following parameters were analyzed: T angle, H angle, the height of the upper lip, the position of the upper and lower lip in relation to the esthetic line. Within the statistical analysis the mean, maximum, minimum, standard deviation, coefficient of variation, two-factor analysis of variance with repeated measures and the factor analysis of variance were calculated using ANOVA, Bonferroni test and Student?s t-test. Results. A significant decrease of angles T and H was noticed in the application of FR-I, from 21.60? to 17.15?, and from 16.45? to 13.40? (p<0.001). FR-I decreased the height of the upper lip from 26.15 mm to 25.85 mm, while Hotz appliance and Balters? Bionator type I increased the height of the upper lip, thereby deteriorating esthetics of the patient. Conclusion. All used orthodontic appliances lead to changes in soft tissue profile in terms of improving facial esthetics, with the most distinctive changes in the application of Fr?nkel?s functional regulator type I, which is the most successful appliance for achieving the overall facial harmony of the patient.

Full textAbstract:
Background:Class II malocclusion is the most common sagittal skeletal discrepancy, with a prevalent skeletal pattern of mandibular retrusion. The correction of mandibular retrusion with functional removable appliance needs a good patient’s compliance; for this reason, some clinicians prefer to use no compliance apparatus.Objective:Objective of the present therapy note is to demonstrate that the use of no compliance apparatus can provide a good correction of skeletal class II malocclusion.Methods:In the present study, authors report a therapy note referred to a 10 years old patient, woman, affected by Class II, with mandibular retrusion and deep bite, treated in 2013 at the Dep. of Orthodontics of Messina University. An orthodontic treatment has been planned with the aim of stimulating mandibular growth; an Herbst appliance with a cantilever design, bonded on first maxillary and mandibular molars, has been used. After eleven months of functional therapy a bilateral molar class I have been obtained.Results:In the therapy note proposed, authors obtained a resolution of mandibular retrusion, a correction of overjet, overbite and dental crowding in both arches, and a bilateral molar and canine class I has been achieved.Conclusion:Herbst appliance seems to be efficient in the correction of II Class Malocclusion, independently from patient’s cooperation; moreover , early correction of Class II malocclusion with functional appliances produces several clinical advantages.

Full textAbstract:
The present study, which focused on Lithuanian 11–15-year-old schoolchildren, was aimed to describe the frequency of orthodontic anomalies in terms of self-reported complaints about malposed teeth and malocclusion and self-reported use of orthodontic appliances (removable or braces) across different sociodemographic strata. Material and methods. The study population comprised 5632 schoolchildren surveyed in the 2005-2006 school year according to the WHO collaborative cross-national HBSC study in Lithuania. Results. Almost half (47.5%) of schoolchildren reported orthodontic complaints. Therefore, only 15.8% of total population or 27.0% of schoolchildren who had orthodontic complaints reported wearing orthodontic appliances. Several municipalities of Lithuania with a high prevalence of orthodontic problems among schoolchildren were identified. Orthodontic problems were more prevalent among girls than boys. The prevalence of orthodontic complaints was not associated with social factors, while the use of orthodontic appliances was significantly related to social determinants. Children from rural areas were 2.44 times less likely of wearing orthodontic appliances than those living in cities, and children from families with low affluence were 2.33 times less likely of wearing orthodontic appliances than children from high-affluence families. Conclusion. There is a considerable variation and high social inequalities in need of orthodontic treatment among schoolchildren across different municipalities in Lithuania.

Aim: To evaluate the oral health and well-being of adolescents with malocclusion who were submitted to orthodontic treatment, assessing the perspective of parents/caregivers and adolescents and to investigate the effects of orthodontic treatment among adolescents on the perception of oral health and well-being, in relation to the opinion of parents/caregivers and adolescents. Methods: Adolescents between 11 and 12 years submitted to orthodontic treatment with fixed appliances at the Federal University of Minas Gerais and their parents/caregivers participated. Adolescents and their parents/caregivers answered questions about the health of adolescents’ teeth, lips, jaws and mouth and about how the condition of adolescents’ teeth, lips, jaws or mouth affects adolescents overall life or well-being before orthodontic treatment onset and 12 months after fixed appliances’ placement. Results: Parents had a significantly more negative perception of the impact of malocclusion on adolescents’ lives or well-being (p<0.001). Adolescents reported that their oral health improved after 12 months of orthodontic treatment (p<0.001). Adolescents also reported that their lives or well-being was significantly less affected after 12 months of orthodontic treatment (p=0.026). Parents/caregivers reported that their adolescents’ oral health improved after 12 months of orthodontic treatment (p<0.001). Parents/caregivers also reported that their adolescents’ lives or well-being was significantly less affected after 12 months of orthodontic treatment (p<0.001). Conclusion: Parents/caregivers have a more negative perception regarding the impact of malocclusion on the life and well-being of an adolescent. After 12 months of orthodontic treatment onset, parents/caregivers and adolescents considered that adolescents’ overall health and well-being had improved.

Relevance. Skeletal malocclusion stands at the head of all oral diseases and is encountered in 32-35% of children and adolescents in Russia [7;12;15]. The number of malocclusions has increase due to various reasons, one of which is early extraction of deciduous carious teeth resulting in impaired vertical dimension and occlusion of teeth [1;14]. Diagnosis with due regard to caries resistance degree and planning of respective operative and orthodontic treatment are indispensable in children with skeletal malocclusion. Purpose – to increase effectiveness of functional treatment of malocclusion in children with various degree of caries resistance.Materials and methods. There were examined 108 patients aged between 6 and 16 with Class I malocclusion according to Angle, abnormal arch-to-arch relationship and tooth position and various degree of caries resistance. 4 groups were formed: high, sufficient mean, decreased mean and low caries resistance of dental enamel. Intensity of carious process was detected in all patients before and after orthodontic treatment. The effectiveness of reminerlization administered by removable orthodontic appliances was evaluated by electrometrical testing of hard dental tissue. Surface EMG was used to assess normalization of tone of maxillofacial muscles in children by average amplitude of biopotentials of superficial masseter and temporalis muscles.Results. Сhanges in caries intensity in children after treatment with removable orthodontic aligners indicate the necessity for remineralization of hard dental tissues during orthodontic treatment and it is confirmed by decrease of electroconductivity of enamel in children with sufficient mean, decreased mean and low degree of dental enamel caries resistance. Increase of biopotential mean amplitude during «total mastication» for masseter and temporal muscles confirms effectiveness of preformed elastic positioner along with myodynamic exercises.Conclusions. The conducted study proves the necessity of comprehensive approach with procedures increasing the degree of caries resistance of hard dental tissues during orthodontic treatment of skeletal malocclusion in children.

Now an orthodontist is a very demandable dental specialist due to increasing number of patients seeking for orthodontic care. Analysis of patients by their age, diagnosis and sex can allow orthodontists to understand more clearly which pathology and which patients are the most prevalent and to find the best approaches to satisfy the clients’ demands. This analysis provides the potential to create more targeted approach in diagnosis, treatment and prevention of malocclusions. At the Department of Postgraduate Education of Orthodontists, Ukrainian Medical Stomatological Academy, we performed an analysis of 2,359 outpatient medical cards (1296 patients, who took treatment in 2019, and 1063 patients, who took treatment in 1999). It is noteworthy that for the 20-year period the number of people seeking for orthodontic care has risen in 9.9 times, despite the rapid development of private dentistry services. The data of the analysis have demonstrated that today adults make up the larges share of the orthodontic patients. Therefore, orthodontic correction by using fixed appliances has become a priority. Moreover, female individuals ask for help more often that is determined by the increase in women's social attitude to their appearance. All this confirms social and psychological significance of orthodontics. As for the male individuals seeking for orthodontic care, their number has been found out to increase in the age 14 – 18 that may be related to the findings revealed at pre-military medical checkups. As for the commonest types of malocclusions for these two periods, I class malocclusion by Angle has been found out as the most prevalent, II class by Angle is ranking the second position and III class by Angle and a deep bite are sharing the third position.

Objective: To assess the orthodontic burden of care of patients from a Brazilian rehabilitation center (Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo [HRAC-USP]). Design: Retrospective. Setting: Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo. Interventions: One hundred files of unilateral complete cleft lip and palate patients who had consecutively finished orthodontic rehabilitation at HRAC-USP were evaluated from January 2011 to January 2013. The duration of orthodontic treatment, number of visits, kilometers traveled, number of appliances and surgical procedures performed were recorded. The sample was divided into 2 subgroups according to severity the interarch relation (Goslon Yardstick score) at the beginning of orthodontic treatment. Mann-Whitney test was applied for intergroup comparison ( P < .05). Results: For the total sample (n = 100), the mean time of orthodontic treatment was 140.2 months, the mean number of orthodontic appointments was 61.8, the mean number of appliances was 10, the mean number of surgical procedures was 6.2, and the mean distance traveled to attend the center for orthodontic appointments was 38,978.5 km. The subgroup with the most severe malocclusion (Goslon yardsticks scores 4 and 5) showed a longer orthodontic treatment length, greater number of surgical procedures, and longer distance traveled than those presenting Goslon yardstick scores 1, 2, and 3. Conclusion: Patients with greater severity of the initial malocclusion experienced a higher burden of care than patients with less severity of the initial malocclusion. To reduce the burden of care, research and efforts should focus on minimizing maxillary growth deficiency related to primary surgery.

Full textAbstract:
The prevalence of malocclusion and a need for orthodontic treatment is high. Orthodontic appliances increase biofilm accumulation by expanding plaque retention sites. The aim of this study was to investigate the self-reported changes in oral hygiene habits among adolescents receiving orthodontic treatment. A cross-sectional study of 291 patients aged 10–17 years (mean (M) = 12.98; standard deviation (SD) = 2.36) was conducted in the Department of Orthodontics, Lithuanian University of Medical Sciences (LSMU) Hospital (Kaunas, Lithuania) during the fall semester (October–January) of the 2017/2018 study year. An anonymous self-administered questionnaire covered background information, experience of orthodontic treatment, oral hygiene habits and the seeking of professional dental care. Statistical data analysis was performed using SPSS version 22. To establish relationships between categorical variables, Chi-squared tests (χ2) were used. A p-value ≤ 0.05 was set to indicate statistically significant difference. The univariate logistic regression analysis evaluated the probability of an event given a certain risk indicator, including odds ratio (OR) and its confidence interval (95% CI). Associations were found between the usage of auxiliary measures (OR = 1.797 (1.118–2.887), p = 0.015), tongue cleaning (OR = 1.712 (1.059–2.767), p = 0.028), mouth rinsing after meals (OR = 1.707 (1.048–2.781), p = 0.032) and experience of orthodontic treatment, respectively. More orthodontic patients underwent professional oral hygiene regularly than non-orthodontic patients (p = 0.024). More patients with fixed orthodontic appliances reported significantly changed oral hygiene habits, while more orthodontic patients with removable appliances did not change their oral hygiene habits.

The success of orthodontic treatment, particularly with removable orthodontic appliances not only relies on theexpertise of the clinician, but also highly depends on the patient's own. It is necessary to know the extent of thesuccess rate of an orthodontic treatment. Assessment of malocclusion severity and treatment outcome has become avery popular object of research conducted by the PAR index. This study aims to determine the success rate oforthodontic treatment with removable appliances based on PAR Index. The research was carried out on March-May2011 with samples of patients dental models who had completed orthodontic treatment in the year 2008-2011 at theDepartment of Ortodonsia RSGMP UNHAS. Sixty six pairs of dental models fulfilled the inclusion criteria and therules of PAR Index. Percentage change in PAR score obtained by 35% in the assessment with no weighted and 36%was assessment by weighted. This results showed the level of orthodontic treatment success include into thecategory of "no change", but with a trend into the category of "a change "with a significant value ρ = 0.000 (ρ <0.05). It was concluded that there was occlusion improvements in orthodontic treatment with removable appliance,although very low and therefore need evaluation and improvement of governance maintenance carried out.

Orthodontic treatments are usually performed using fixed brackets or removable oral appliances, which are traditionally made from alginate impressions and wax registrations. Among removable devices, eruption guidance appliances are used for early orthodontic treatments in order to intercept and prevent malocclusion problems. Commercially available eruption guidance appliances, however, are symmetric devices produced using a few standard sizes. For this reason, they are not able to meet all the specific patient’s needs since the actual dental anatomies present various geometries and asymmetric conditions. In this article, a computer-aided design-based methodology for the design and manufacturing of a patient-specific eruption guidance appliances is presented. The proposed approach is based on the digitalization of several steps of the overall process: from the digital reconstruction of patients’ anatomies to the manufacturing of customized appliances. A finite element model has been developed to evaluate the temporomandibular joint disks stress level caused by using symmetric eruption guidance appliances with different teeth misalignment conditions. The developed model can then be used to guide the design of a patient-specific appliance with the aim at reducing the patient discomfort. At this purpose, two different customization levels are proposed in order to face both arches and single tooth misalignment issues. A low-cost manufacturing process, based on an additive manufacturing technique, is finally presented and discussed.

Objective : Overjet is a horizontal relationship between maxillary and mandibular incisors. Normal range from overjet is 2-4 mm. Increased overjet is marked by maxillary incisor’s protrusion. A 6 mm overjet will have impact on psychological and social relationship of children due to the aesthetics of the face profile. Increased overjet has relationship with Class II Angle malocclusion, Class II skeletal sagittal relationship, and mandibular retrognathia. Clinical problem caused by increased overjet in children are maxillary permanent incisors trauma in growing age, damaged periodontal tissue, lip incompetency, social impact such as lack of confidence in children, and also increased overjet has a close relationship with Temporomandibular Disorder (TMD) sign and symptoms.Methods : Increased overjet case can be managed by maxillary retraction of labial segment and increasing mandibular labial segment. Case management are based on skeletal and soft tissue pattern and patient’s age. Reducing overjet can be based on using several appliances, such as functional removable appliance to modify dental and skeletal relationship, fixed orthodontic appliances with tipping and bodily movement or using jaw reposition by orthognathic surgery.Results : One of the effective appliance to reduce overjet, especially Class II malocclusion treatment is Twin Block Functional Appliances developed by Clark. Twin Block appliances is used for developing age children in certain time period to support mandibular growth. This appliance is easy to use, so the patient cooperativity can be maintained. Maximum treatment depends on children’s cooperativity. By using Twin Block functional appliance, we can observe that early treatment can be effective to reduce overjet, to change skeletal pattern, and to increase children psychology such as self-confidence by making aesthetic changes to their faces significantly.[B1] Conclusion : This appliances is made with 70o angle to occlusal plane. Maxillary arch lateral expansion can be achieved with expansion screw. Patient will be instructed to use the appliance for 24 hours a day.[B2]

Objectives: The aims of this study were to assess the prevalence and associated contributory factors for discontinuation of orthodontic treatment. Materials and Methods: A hospital-based retrospective study was conducted with the treatment records, whose orthodontic treatment was commenced in the year 2015 at the Division of Orthodontics, University Dental Hospital, Peradeniya. Information regarding age, gender, type of malocclusion, Index of Orthodontic Treatment Need, appliance type, duration of treatment, extraction versus non-extraction, stage of treatment, and the cost of treatment was obtained from the patient’s records. Statistical analysis was performed using the statistical software R 3.5.0. Results: The sample consisted of 310 treatment cases, of which 40 (12.9%) patients were discontinued. Among the discontinued patients, 50.6% were male and 49.3% were female. The discontinuation rate in the group of 12–17 years was higher than the other age groups, which was statistically significant (P = 0.005). Among the group of discontinued treatment, 49.3% were of Class II division 1 malocclusion and 37.1% and 37.4% of patients were in Grade 3 and 4 of IOTN, respectively. About 37% of patients have been discontinued before completion of 1 year which was statistically significant (P = 0.0005). About 59.5% of non-extraction patients were in the treatment discontinuation group which was also statistically significant (P = 0.023). About 32.5% of the patients who discontinued have obtained the treatment with the lowest cost with statistical significance (P = 0.026). Conclusion: Children with borderline and moderate occlusal irregularities treated with simple removable appliances which are affordable with low cost were more prone to discontinue in the early phase of active treatment.

ABSTRACT Objectives To determine factors that could predict Class II/1 malocclusion patient compliance during functional treatment. Materials and Methods The sample consisted of 77 subjects (aged 11–13 years; 47% girls) presenting with Class II/1 malocclusion. Inclusion criteria were distal molar relationship, overjet greater than 5 mm, and confirmed pubertal growth spurt. Removable functional appliances (62% Twin Block [TB], 38% Sander Bite Jumping [BJ]) with built-in maxillary expansion screws were used. Follow-up period was 1 year. Patients and parents independently filled out the Child Perception Questionnaire, Parental/Caregiver Perception Questionnaire, and Family Impact Scale to assess emotional and social well-being, oral symptoms, functional limitations, parental emotions, family activities, conflicts, and financial burden as possible predictors of compliance during treatment. Sex, overjet, and appliance type were also analyzed. Results There were more noncompliant than compliant patients (55% vs 45%). Parental perception of altered emotional well-being of their children was the strongest predictor, increasing compliance odds 3.4 times (95% confidence interval [CI], 1.2–9.4; P = .017). Patients were 3.2 times (95% CI, 1.1–9.3; P = .033) more likely to cooperate with TB compared with BJ appliance. OJ ≥ 8 mm increased compliance odds 3.1 times (95% CI, 1.0–9.4; P = .044). Conclusions Parental perception of child's emotional well-being alteration, severity of malocclusion, and type of appliance are major predictors of compliance. Psychosocial issues and oral function limitations reported by children and family impact are of negligible influence.

A 46-year-old male Caucasian with traumatically induced maxillary retrusion was referred for orthodontic treatment, eight weeks after the original fracture had occurred. Initial surgical reduction and fixation had been successful, when a second traumatic episode was encountered. This resulted in a further degree of posterior maxillary displacement, which was resistant to further surgical reduction. The resulting Class III malocclusion was treated using maxillary protraction headgear, in conjunction with removable orthodontic appliances and intermaxillary traction. Appliances were worn full time and inter-arch correction was achieved in six months. The resulting occlusion proved to be stable following the cessation of active treatment.

Purpose: An update is provided on the different types of early treatment for class III malocclusions of maxillary origin. There is an increasing tendency to prescribe maxillary orthopedic treatment with skeletal an-chorage, with the purpose of enhancing the skeletal and reducing the dentoalveolar effects - offering a management option for children with important deformations that otherwise would have to wait until adult age to receive surgical treatment. Method: A literature review has been made of maxillary bone orthopedic traction appliances in growing children with class III malocclusions. A Medline (PubMed) search was made using the following MeSH terms: Cephalometric, Child, Malocclusion class III / therapy, Extraoral traction appliances, Palatal expansion, Bone plates, Skeletal anchorage, Orthodontic anchorage. Results: Many articles show that the greatest maxillary advances are obtained at very early ages, though with a greater tendency towards relapse. However, skeletal anchorage has been seen to afford a lesser relapse rate and greater dentofacial orthopedic efficiency due to its low dentoalveolar impact. In any case, further randomized clinical studies are needed to firmly establish the quantifiable differences in terms of maxillary advance, optimum traction age, optimum traction appliance and potential side effects. At present, the incorporation of surgically inserted bone anchorage appliances (miniplates and miniscrews) offers a purely orthopedic approach to treatment, with minimization of the undesirable side effects of traditional dentofacial orthopedic compensation based on dentoalveolar anchorage. Nevertheless, further studies are needed to consolidate the supporting scientific evidence in this field.

Full textAbstract:
ABSTRACT Objectives: To compare (1) speech performance based on an auditive analysis and sonagraphy and (2) levels of oral impairment between fixed lingual and labial orthodontic appliances. Materials and Methods: Thirty-four patients with Class I division 1 malocclusion and moderate crowding of upper teeth were distributed randomly into two groups. Seventeen patients in group A (mean age: 20.6 years; standard deviation [SD]: 2.9 years) were treated with fixed lingual appliances (Stealth®, AO, Sheboygan, Wisc), whereas 17 patients in group B (mean age: 21.8 years; SD: 3.3 years) were treated with conventional fixed labial appliances. Speech performance was tested using spectrographic analysis of fricative /s/ sound before, immediately after (T1), 1 month after, and 3 months after bracket placement. The levels of oral impairment were assessed using standardized questionnaires. Results: A significant deterioration in articulation was recorded at all assessment times in group A but only at T1 in group B. Significant intergroup differences were recorded at all assessment times (P < .001). Speech difficulties were significantly higher in the lingual brackets group after 1 month of bracket placement (P < .001). Soft tissue irritation and chewing difficulty were significantly higher in the lingual appliance group after 24 hours of bracket placement (P < .001). Conclusions: The lingual appliance is more problematic than the labial one in terms of speech articulation. Although patients with both appliances suffered from different degrees of oral impairment, patients with lingual appliances had more untoward effects, particularly during the first month of treatment.

Full textAbstract:
This cephalometric study investigates the changes in the facial skeleton and dento-alveolar structures which occur during orthodontic treatment of the Class II Division 1 malocclusion by extraction of four first premolars followed by fixed appliances. The Begg and edgewise appliances are compared, and both are contrasted with a group of untreated Class II Division 1 subjects. The main effects of treatment were in the dento-alveolar structures, the changes in the overall facial pattern being small and largely due to extrusion of the molars during overbite reduction. Molar extrusion tended to interrupt forward growth rotation of the mandible, temporarily making it more backwards in direction, and increasing the lower anterior face height. An increase in the posterior lower face height was also noted in the edgewise group. Whilst SNA, and therefore ANB, reduced significantly during treatment, this was probably the result of palatal root torque to the upper incisors. The Begg appliance was more successful than edgewise in this respect.

Its popularity is attributed to its high patient adaptability and ability to produce rapid treatment changes. The twin block and lip bumper can be combined depending on the patient’s cases. The purpose of therapy with twin block is effective in mandibular growth deficiencies to induce supplementary lengthening of mandibular by stimulating increased growth at the condylar cartilage. The patient was a ten-year-old male patient with skeletal Class II malocclusion. He had a convex facial profile, SNA (sella, nasion, A point) angle of 77.5°, SNB (sella, nasion, B point) angle of 73.0°, ANB (A point, nasion, B point) angle of 4.5°, overjet of 6.5 mm, overbite of 11/41 = 5.0 mm, 21/31 = 4.5 mm, abnormal upper labial frenulum, crossbite in the second left premolar of maxilla, crowded anterior teeth of mandibular, deficiency of mandibular growth, lower lip sucking habit, anterior teeth of maxilla with diastema and proclination. Orthodontic treatment for patient is a combination of twin block and lip bumper appliances. After seven months, frenectomy is used to eliminate and correct the spacing in the frenulum. After 10 months, the patient’s skeletal and profile had improved to skeletal Class I malocclusion, SNA angle of 78.0°, SNB angle of 75.0°, ANB angle of 3.0°, overbite and overjet of 4.0 mm, and the lower lip sucking habit had stopped. Twin block and lip bumper appliances are particularly good alternative treatment in managing selected cases of skeletal Class II malocclusion.

Functional appliance is an effective way of treating skeletal Class II malocclusion in children and adolescents. A 12 months stepwise mandibular advancement protocol with Herbst appliance has been proved to enhance condylar growth and improve mandibular prognathism. The present case report documents a 12-year-old boy presenting with Angle’s Class II, division 1 malocclusion associated with excessive overjet (11 mm), 100% deep bite, and retrognathic mandible. He was treated by a phase I growth modification therapy using twin block appliance with lip pads in a stepwise mandibular advancement protocol followed by a phase II preadjusted Edgewise appliance therapy.

The approach to skeletal dysmorphisms in the maxillofacial area usually requires an orthodontic treatment by means of fixed appliances, both before and after the surgical phase. Since its introduction, Invisalign system has become a popular treatment choice for the clinicians because of the aesthetics and comfort of the removable clear aligners compared with the traditional appliances. Therefore, the aim of the present report was to illustrate the management of a malocclusion by means of Invisalign system associated with the traditional surgical technique. The present paper shows a case of a 23-year-old male patient characterized by a Class III malocclusion with lateral deviation of the mandible to the left side and cross-bite on teeth 2.2, 2.3, and 2.4. Invisalign system was used during the pre- and postsurgical phases rather than fixed appliances. The posttreatment cephalometric analysis emphasized the stability of the dental and skeletal symmetry corrections, occlusion and functional balance, over a 6-year follow-up. The results achieved at the end of the treatment showed how Invisalign can be effective in the management of the orthodontic phases in orthognathic surgery. The follow-up after 6 years emphasizes the stability of the treatment over time.

OBJECTIVE: The aim of this study was to cephalometrically assess the skeletal and dentoalveolar effects of Class II malocclusion treatment performed with the Jones Jig appliance followed by fixed appliances. METHODS: The sample comprised 25 patients with Class II malocclusion treated with the Jones Jig appliance followed by fixed appliances, at a mean initial age of 12.90 years old. The mean time of the entire orthodontic treatment was 3.89 years. The distalization phase lasted for 0.85 years, after which the fixed appliance was used for 3.04 years. Cephalograms were used at initial (T1), post-distalization (T2) and final phases of treatment (T3). For intragroup comparison of the three phases evaluated, dependent ANOVA and Tukey tests were used. RESULTS: Jones Jig appliance did not interfere in the maxillary and mandibular component and did not change maxillomandibular relationship. Jones Jig appliance promoted distalization of first molars with anchorage loss, mesialization and significant extrusion of first and second premolars, as well as a significant increase in anterior face height at the end of treatment. The majority of adverse effects that occur during intraoral distalization are subsequently corrected during corrective mechanics. Buccal inclination and protrusion of mandibular incisors were identified. By the end of treatment, correction of overjet and overbite was observed. CONCLUSIONS: Jones Jig appliance promoted distalization of first molars with anchorage loss represented by significant mesial movement and extrusion of first and second premolars, in addition to a significant increase in anterior face height.

Full textAbstract:
Dentoskeletal class II malocclusion due to a protruded upper dental arch is a major reason for an orthodontic treatment. In these cases, the correction of class II can be hindered by molar distalization, obtained with ‘no-compliance therapy’ that involves the use of appliances which minimize the need for such co-operation and attempt to maximize the predictability of results. The aim of this review was to outline the effectiveness of no-compliance fixed orthodontic devices in the molar distalization. After selection according to the inclusion/exclusion criteria, 16 articles from 2000 to 2019 were qualified for the final analysis. The literature shows various no-compliance fixed devices whose effect is to distalize the maxillary molars. The present revision allows to conclude that there is a need to increase the number of studies, especially with regard to the most recently introduced devices in the literature. The analysed studies allow to hypothesize that these appliances act with a minimal variability of molar distalization and disto-inclination among them, although different effects among the appliances can be observed as regards to the anchorage.

The treatment of class III malocclusion differs depending on the age of the patient. In adult patients, alternatives include either orthodontic dentoalveolar compensation treatment or a combined ortho-surgical approach. The aim of this paper is to present the orthodontic and surgical treatment of a 24 year old adult patient with increased anterior face height, a class III skeletal pattern and mandibular asymetry. Previous orthodontic treatment with removable appliances obtained a 1 mm overbite and overjet. Intraorally, class III molar relationship was observed, proclined upper incisors, retroclined lower incisors and a deviated lower midline. The main complaint was facial esthetics which required surgical intevention. After pre-surgical orthodontic preparation the maxilla was repositioned by a Le Fort I osteotomy and the mandible was set back using the Obwegeser-Dal Pont method. Final assesment revealed both functional and esthetic dentofacial results. A combination of orthodontic treatment and orthognathic surgery is often required in adult patients with dental malocclusion and skeletal discrepancies.

Introduction. Skeletal malocclusions, especially those with a prominent vertical component, always present a challenge for the interdisciplinary approach to their treatment planning. The aim of this report is to present a patient with a complex skeletal deformity in all three directions (vertical, sagittal and transverse). Case report. A twenty-four year old female patient with a skeletal Class III malocclusion, open bite and laterognathia, was firstly treated by orthodontic fixed appliances, whereas the dental decompensation of dentoalveolar structures was carried out and adjusted to their bone structures, thus enabling an adequate and sufficient reposition of the jaw. A surgical correction included bi-maxillary osteotomy due to pronounced vertical cephalometric parameters, necessitating a posterior maxillary intrusion and mandibular repositioning. In that manner, the relapse was prevented and a long-term stable result obtained. In the retention period, the patient wore removable bi-maxillary retention devices. Conclusion. The combined orthodontic-surgical treatment provided the Class I occlusion with aesthetic and functionally satisfactory results which were envisioned by the treatment plan.

Full textAbstract:
Rapid technological advancements in the orthodontic field in recent years have enabled clinicians to treat an increasing number of patients using non extraction approaches. Self ligating brackets are becoming increasingly popular as they enable rapid movement of teeth with lateral arch development negating the need to extract teeth.
Two Class I malocclusion patients presenting with moderate to severe anterior crowding were treated non-extraction with self ligating fixed appliances. The cases presented illustrate the versatility of self ligating brackets in management of malocclusions with extensive transverse and sagittal components. A review of literature discussing the changing paradigms from extraction to non extraction and use of self ligation is highlighted.

Background: Tongue thrusting is a behavior pattern in which the tongue protrudes through the anterior incisors and pushes the anterior teeth at rest position, during speech or swallowing. This bad habit causes malocclusion, but removable or fixed tongue crib appliance can be used to eliminate it. Purpose: To know various kinds of fixed tongue crib that can be used to overcome tongue thrust habit. Review: Habit is a repeated behavior pattern in the normal development stage. Tongue thrust makes oral muscle imbalance which eventually resulted in malocclusions such as incisor protruded and open bite. Several efforts can be done to overcome this habit including speech therapy, myofunctional therapy, tongue exercise and tongue crib orthodontic appliance usage. Tongue crib is used to returns the tongue to the normal position. Various forms of tongue crib are almost the same in the way they are made by soldering the crib to the maxillary first molar band. Conclusion: Tongue thrust habit can be corrected with fixed or removable tongue crib appliances such as hybrid habit correcting appliance, tongue crib with cold cured acrylic tongue shield, fixed palatal crib with transpalatal arch, fixed tongue loops, tongue fence, and upper hay rake.
