Abstract:

Background: Malocclusion is a disease with a high incidence rate that is harmful to humans’ health. Fixed orthodontics is an effective method for the treatment of malocclusion. However, the orthodontic process takes a long time, requires frequent visits, causes pain, and increases the risk of complications. Since orthodontic treatment is lengthy, painful and unbearable, and even leads patients to abandon orthodontic treatment, therefore, how to shorten orthodontic treatment duration, and reduce pain is a research hotspot in the orthodontic field. Objective: The study aimed to provide an overview of the existing orthodontic accelerating device and introduce their classification, characteristics and development. Methods: This paper reviewed various productions and patents related to the orthodontic accelerating device. The structural characteristics, differentiations, and applications of the existing orthodontic accelerating device are also introduced. Results: The existing orthodontic accelerating devices were analyzed and compared, and the typical characteristics were concluded. The main problems in its development were analyzed, the development trend was foreseen, and the current and future research on the productions and patents related to the orthodontic accelerating device is discussed. Conclusion: The orthodontic accelerating device is composed of a vibration device having electrical stimulation, magnetic field, a low-level laser, and an ultrasonic device according to the application of different physical loads. Orthodontic accelerating device can effectively reduce orthodontic treatment time by 30%-50%, and can reduce the risk of complications and pain. The dose of the physical load determines the effect of the device. So, an optimal loading dose should be selected . Compared with vibrating devices, other types of devices are less used in clinical practice, therefore, such products and patents should be invented in the future.

Abstract:

Background In this study, we aimed to evaluate the inclination of orthodontic research published in original articles in three of the most popular and recognized orthodontic journals with high impact factor; American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), the Angle Orthodontist (AO), and European Journal of Orthodontics (EJO) published in a 5-year duration time frame (2010–2014). Materials and Methods Online search with supplementary hand searching was undertaken for original research articles in these three orthodontic journals from 2010 to 2014. Classification of data was completed autonomously by manual and direct appraisal of the manuscript of each journal. Results and Conclusion Three thousand one hundred and forty articles published in AJODO, AO, and EJO in the particular time period were selected, out of which 1783 original research study articles (56.78%) were appraised for classification in their various respective knowledge domains. AO (82.73%) and EJO (76.99%) were relatively more committed toward publication of research work in comparison to AJODO (34.55%). Research articles based on perception and questionnaires (12%), temporary anchorage devices (11%), cone-beam computed tomography (8%), invisible orthodontics (lingual orthodontics, clear aligners, esthetic brackets, and wires) (5%), and airway examination (5%) were the five most recurrently selected subjects of interest (41%) in these three journals during the observation period. The total number of research articles published in the three journals reduced statistically significantly in 2014 when compared to 2010.

Abstract:

ABSTRACT Efficient anchorage control is one of the important requisites for successful orthodontic treatment. The conventional means of anchorage control have been the use of transpalatal /lingual arch and palatal button but disadvantage is they do not provide absolute anchorage. Though the use of headgear provide efficient anchorage control, the patients are not compliant in using a headgear. Orthodontic implants have provided us with noncompliant and efficient means of anchorage control. This article traces the journey of development of implants as temporary anchorage devices.

Abstract:

Paradigms have started to shift in the orthodontic world since the introduction of mini-implants in the anchorage armamentarium. Various forms of skeletal anchorage, including miniscrews and miniplates, have been reported in the literature. Recently, great emphasis has been placed on the miniscrew type of temporary anchorage device (TAD). These devices are small, are implanted with a relatively simple surgical procedure, and increase the potential for better orthodontic results. Therefore, miniscrews not only free orthodontists from anchorage-demanding cases, but they also enable clinicians to have good control over tooth movement in 3 dimensions. The miniplate type also produces significant improvements in treatment outcomes and has widened the spectrum of orthodontics. The purpose of this paper is to update clinicians on the current concepts and versatile uses and clinical applications of skeletal anchorage in orthodontics.

Abstract:

The period of the first phase of replacement bite in children in the Russian Federation corresponds to the period of primary school age, which is considered one of the critical periods in the child's development, due to increased emotional loads, and children aged 67 years are at risk for developing combined orthodontic and speech therapy pathologies.The complexity of the correction of orthodontic treatment at this age patients associated with lack of coordination between the orthodontist and speech therapist: a speech therapist does not accept the correction of the patient, until he had reached the incisors contact, and the orthodontist begins orthodontic treatment, since it prevents the wrong position and function of tounge.Most modern removable orthodontic appliance restrict the mobility of the tongue to some extent, thus forcing the child to move it down and back, suppressing its tone. In addition, the use of these devices prevents speech therapy correction, since it violates the automation of sound reproduction. The use of removable orthodontic appliance has positive orthodontic effects, but at the same time, contributes to the development of the second and third level of incorrect sound reproduction.In our experience, the device of choice in such situations is the Haas appliance. The use of the Haas appliance gives the fastest orthodontic effects, and myofuction therapy, speech therapy, as well as ottorhinolaryngological treatment can be carried out at the same time, which helps to consolidate the result and reduces the likelihood of relapses to a minimum.

Abstract:

Subperiosteal bone-bonding devices have been proposed for less invasive treatments in orthodontics. The device is osseointegrated onto a bone surface without fixation screws and is expected to rapidly attain a bone-bonding strength that successfully meets clinical performance. Hence, the device’s optimum shape for rapid and strong bone bonding was examined in this study by finite element analyses. First, a stress analysis was performed for a circular rod device with an orthodontic force parallel to the bone surface, and the estimate of the bone-bonding strength based on the bone fracture criterion was verified with the results of an animal experiment. In total, four cross-sectional rod geometries were investigated: circular (Cr), elliptical (El), semicircular (Sc), and rectangular (Rc). By changing the height of the newly formed bone to mimic the progression of new bone formation, the estimation of the bone-bonding strength was repeated for each geometry. The rod with the Rc cross section exhibited the best performance, followed by those with the Sc, El, and Cr cross sections, from the aspects of the rapid acquisition of strength and the strength itself. Thus, the rectangular cross section is the best for rod-like subperiosteal devices for rapid bone bonding.

Abstract:

The orthodontic minitubes system (FLOWJAC ® System, Bogotá, Colombia) is an innovating system that blend the selfligating philosophy techniques and a lowprofile appliance. The FLOWJAC® System works with low orthodontic forces, same as selfligation devices. The system uses heat-treated wires with better physical properties such as hysteresis when is compare with traditional wires. However, the FLOWJAC® technique doesn´t use a wire sequence to get a “working wire”, just a 0,014 Copper NiTi. The clinician in each appointment must modify the minitube location to the clinical desire teeth position. The present report blend FLOWJAC® devices in the upper arch and clear selfligation in the lower arch. The patient treated has mandibular bone resorption due a alloplastic chin augmentation. The root apex from first right premolar to the first left premolar seen to be near to the resorption area using Cone Beam Computer Tomography. That´s the reason why we use a pre-adjust devices in the lower arch, to avoid pulpar and periodontal counter effects. This case was finished with proper functional and aesthetics objectives; such as molar and canine class I, anterior open bite closure with 20% of overbite, coincidence of dental smile arch with lower lip, and without root and pulpar counter effects. The porpoise of this report is to present an orthodontic case with bone resorption on right premolar and incisors area of the mandible. The case was treated with selfligation orthodontics system; FLOWJAC® System in the upper arch and Empower Clear® (American Orthodontics Shebboyiang, USA) in the lower arch and could be done with a precise diagnosis and adequate treatment planning.

Abstract:

Many scientists were engaged in the study of dentition anthropometry in patients before and after orthodontic treatment. The most common orthodontic device for the treatment of malocclusion class III is a regulator of Frenkel type III. We have proposed a new orthodontic device for the treatment of patients with malocclusion class III and premature removal of temporary molars. Aim - to compare changes of dentitions in children aged 6-12 before and after orthodontic treatment of malocclusion class III using the device of own design and regulator of Frenkel type III. Materials and methods. 110 patients at the age of 6-12 years with malocclusion class III were treated with the use of removable orthodontic curative devices. Anthropometry of dentitions was conducted before and after the treatment. Results. After applying the new diagnostic and treatment algorithm, the duration of orthodontic treatment of patients with malocclusion class III reduced by 1.3 times. The children's quality of life have improved after orthodontic treatment. Conclusion. In case of children aged 6-12 years with malocclusion class III associated with premature removal of temporary molars, it is necessary to use the device of our design. This will give the opportunity not only to fix the dento-facial abnormality, but also to restore the functions of chewing, swallowing and speech.

Abstract:

INTRODUCTION: Since the beginning of miniscrews as orthodontic anchorage, many applications have been described in the literature. Among these, one is the uprighting of mesially inclined molars. In regard to the mechanical aspects, however, there is little information about the application of orthodontic forces using such devices. OBJECTIVE: The objective of this study was to describe a miniscrew supported spring for uprighting of mesially inclined molars. With this device, one can achieve the correct use of orthodontic biomechanics, thus favoring more predictable tooth movements and preventing unwanted movements from occurring.

Abstract:

Orthodontic anchorage is a necessity for every treatment and must be carefully evaluated by the orthodontist. It is defined as the resistance to unwanted dental movement of a tooth or a number of teeth by using different techniques. The purpose of the present paper is to highlight the subperiosteal anchorage applied to orthodontics; this technique has been debated in the literature and the purpose here is to summarize the fields of application. During the first check of previous literature 548 results were found, which have been reduced to 19 selected papers after application of the inclusion criteria and the elimination of duplicates. Multiple electronic databases were searched from 1 January 1995 to 31 December 2020 in order to identify papers eligible for current review. The data obtained by this review underlined the versatility of onplants used as absolute anchorage during orthodontic treatments, the advantages and disadvantages, the biomechanical properties and survival rates, and the clinical procedure. Further clinical studies and research are required to explore other kinds of application and to state specific guidelines; however, this study represents an update and a starting point for clinicians who want to use these devices and for further improvement of the technique.

Abstract:

Rapid maxillary expansion is employed for the treatment of cross-bite and deficiency of transversal dimension of the maxilla in patients with and without cleft of palate and lip. For this procedure, generally, different orthodontic appliances and devices generating significant transversal forces are used. The aim of this study is the finite-element analysis of stresses and displacements of the skull without palate cleft and the skull with unilateral and bilateral cleft after activation of the Hyrax orthodontic device. Two different constructions of the orthodontic device Hyrax with different positions of the screw relative palate are considered. In the first case, the screw is in the occlusal horizontal plane, and in the other, the screw is located near the palate. Activation of the orthodontic device corresponds to the rotation of the screw on one-quarter turn. It is established that the screw position significantly affects the distributions of stresses in skull and displacements of the cranium without palate cleft and with unilateral or bilateral palate cleft. Stresses in the bone structures of the craniums without cleft and with cleft are transferred from the maxilla to the pterygoid plate and pharyngeal tubercle if the screw displaces from the occlusal plane to the palate. Depending on the construction of the orthodontic appliance, the maxilla halves in the transversal plane are unfolded or the whole skull is entirely rotated in the sagittal plane. The stresses patterns and displacements of the skull with bilateral palate cleft are almost unchanged after activation of the orthodontic devices with different positions of the screw, only magnitudes of stresses and displacements are changed. The obtained results can be used for design of orthodontic appliances with the Hyrax screw, as well as for planning of osteotomies during the surgical assistance of the rapid maxillary expansion.

Abstract:

Orthodontic implants have become a reliable method in orthodontic practice for providing temporary additional anchorage. These devices are useful to control skeletal anchorage in less compliant patients or in cases where absolute anchorage is necessary. There are a great number of advantages in this new approach which include easy insertion, decreased patient discomfort, low price, immediate loading, reduced diameter, versatility in the forces to be used, ease of cleaning, and ease of removal. However, a proper management of the screws by the practitioner is necessary in order to increase the success rate of the technique. The purpose of this paper is to update practitioners on the current concepts of orthodontic implants and orthodontic mechanics.

Abstract:

Background/Aim. Orthodontic treatment enables the establishment of functional occlusion and improvement of oral health, however, it increases the risk of periodontal disease development. The aim of this paper was to examine the efficiency of the applied programme for the prevention of gingivitis in children undergoing the fixed orthodontic appliance therapy and to determine the most efficient devices and techniques for maintaining oral hygiene during orthodontic treatment. Methods. The study included 80 patients of both genders - 60 patients comprised the experimental group and 20 patients comprised the control group. All of them were patients of the Clinic for Orthodontics at the School of Dentistry in Belgrade, aged between 13 and 18. The Silness-L?e Plaque Index (PI) was utilised for the assessment of oral hygiene quality and Silness-L?e Gingival Index (GI) and M?hlemann Papilla Bleeding Index (PBI) were utilised for the assessment of gingival state. Checkups were conducted as a single-blind study at the beginning and after the first, the third and the sixth month of the preventive and prophylactic programme. Results. During the observed period, a statistically significant change in PI, GI and PBI values was noticed (p < 0.005), as well as the difference in the dynamics of value changes during the periods between the observed groups. Conclusion. The preventive programme, applied to children undergoing the fixed orthodontic appliance therapy, had a positive effect both on oral hygiene quality and gingival state. The values of the examined parameters of the patients from the experimental group were significantly lower in comparison with those of the patients from the control group. The most efficient combination of devices for oral hygiene during orthodontic treatment was: a Curaprox CP5460 toothbrush, CD Ortho 60 orthodontic toothbrush and Curaprox CPS 14 interdental brush.

Abstract:

Microimplant anchors, also known as temporary anchorage devices, mini- and micro-screws, have been used to enhance orthodontic anchorage for difficult tooth movements. Here, the authors describe how microimplants can be used to help treat craniofacial patients by supporting distraction osteogenesis procedures, maxillary protraction procedures, cleft segment expansion and stabilization, and tooth movement into narrow alveolar cleft sites. While most craniofacial patients are treated without microimplants, it would be worthwhile to identify which cases could benefit from microimplant anchorage. As an adjunct to orthodontic treatment, the microimplant offers a potential method for solving troublesome orthodontic and surgical problems such as guiding distraction procedures with orthodontics when primary teeth are exfoliating, addressing residual maxillary cants after vertical distraction osteogenesis of a ramus, stabilizing an edentulous premaxilla, and moving teeth into atrophic alveolar ridges. These cases are presented to open a dialogue on their possible uses in craniofacial patients.

Abstract:

INTRODUCTION: The finite element method (FEM) is an engineering resource applied to calculate the stress and deformation of complex structures, and has been widely used in orthodontic research. With the advantage of being a non-invasive and accurate method that provides quantitative and detailed data on the physiological reactions possible to occur in tissues, applying the FEM can anticipate the visualization of these tissue responses through the observation of areas of stress created from applied orthodontic mechanics. OBJECTIVE: This article aims at reviewing and discussing the stages of the finite element method application and its applicability in Orthodontics. RESULTS: FEM is able to evaluate the stress distribution at the interface between periodontal ligament and alveolar bone, and the shifting trend in various types of tooth movement when using different types of orthodontic devices. Therefore, it is necessary to know specific software for this purpose. CONCLUSIONS: FEM is an important experimental method to answer questions about tooth movement, overcoming the disadvantages of other experimental methods.

Abstract:

ABSTRACT In recent times, the use of miniscrew implants to obtain absolute anchorage has gained momentum in clinical orthodontics as rigid anchorage modality. Miniscrew implants offers many advantages when used as temporary anchorage devices like, easy placement and removal, immediate loading, can be used in a variety of locations, provide absolute anchorage, economic and requires less patient cooperation. This makes them as a necessary treatment option in cases with critical anchorage that would have otherwise resulted in anchorage loss if treated with conventional means of anchorage. The aim of this comprehensive review is to highlight the gradual evolution, clinical use, advantages and disadvantages of the miniscrew implants when used to obtain a temporary but absolute skeletal anchorage for orthodontic applications.

Abstract:

Introduction: Orthodontic treatment often causes inflammatory diseases in the oral cavity. The aim: То іncrease the effectiveness of prevention of inflammatory complications in the provision of orthodontic care to children with dentomaxillary anomalies using nonremovable orthodontic devices on the basis of study of clinical and biochemical parameters. Materials and methods: The study was conducted among 100 patients divided into two groups: control and experimental group 2 (50 patients in each). The control group included healthy children without dento-maxillary anomalies. The second group were children aged 9-15 years with dento-maxillary anomalies which used non-removable (bracket systems) orthodontic devices. The oral fluid was collected at the beginning of the medical application of orthodontic devices (at the first day of treatment in the clinic) and after 3 and 6 months of treatment. The study included the definition of the oral hygiene degree by using the Green-Vermillion index (OHI-S), the modified Fedorov-Volodkin’s and Siness-Loe index, the determination of hydrogen sulfide and total protein levels, the content of nitrogen metabolites in the oral liquid. Results: The use of non-removable orthodontic devices led to signs of inflammation in the oral cavity. This was accompanied by a deterioration of the oral hygiene, increase the total protein, hydrogen sulfide and nitrogen metabolites levels in the oral fluid. Conclusions: Complex accounting is required of keeping oral hygiene in good condition, level determination of total protein, hydrogen sulfide and nitrogen metabolites for the prevention of the development of inflammatory diseases in the provision of orthodontic care.

Abstract:

BACKGROUND Clear aligners are orthodontic devices that are transparent, a plastic used to correct malaligned teeth. Here patient wears a series of customized clear, removable aligners that gradually move the teeth to the desired position. The clear aligner system is a modern adaptation of the systems described since the middle of the 20th century, therefore there were different devices and philosophies that have led to its creation and the system has evolved a lot over the decades. Clear aligner therapy has been a part of the orthodontic practice for years, but, popularity was increased since the introduction of Invisalign appliances (Align Technology) in 1998. There are almost 27 different clear aligner products currently on offer for orthodontic treatment. Nowadays, more people prefer clear aligner treatment because it is aesthetically superior to brackets and lingual orthodontics. The superiority of clear aligners lies in their aesthetics. The optical properties of the clear aligner material play a major role in aesthetics. The rising demand among adult patients for “invisible” orthodontic treatment has led to an exponential growth in the clear aligner market. Indeed, these aligners have a low aesthetic impact, as well as being able to effectively and progressively guide the teeth into their programmed positions. They are also removable and therefore do not hamper oral hygiene maintenance, in turn reducing the risk of white spots, caries, gingivitis and periodontal disease. All the materials do not possess the same chemical composition. The properties change before and after wear. In this article, we bring out the different materials used for the manufacture of clear aligners and their various properties.

Abstract:

Introduction. With an increasing demand for orthodontic treatment for adult patients, orthodontic professionals are constantly seeking novel strategies and technologies that can accelerate tooth movement in order to shorten the treatment period. For instance, in recent years, the influences of different surgical techniques on orthodontic tooth movement in the ipsilateral side of surgery were intensively investigated. Here, we attempt to examine if corticotomy could also affect the rate of tooth movement in the contralateral side of the surgery by using a rodent model. Materials and Methods. 72 eight-week-old Sprague-Dawley rats were randomly divided into three groups as follows: the Control group (orthodontic treatment devices delivered only, no tooth movement), the orthodontic tooth movement (OTM) group (orthodontic treatment devices delivered and orthodontic treatment performed), and the Corticotomy + OTM group (remote corticotomy performed, orthodontic treatment devices delivered, followed by orthodontic treatment). The surgical procedure was conducted on the right side of the maxilla at the time of appliance placement and a force of 60 g was applied between the maxillary left first molar and maxillary incisors using nickel-titanium springs to stimulate OTM. The OTM distance and speed were tracked at 3, 7, 14, and 28 days post-surgery, followed by histological and immunohistochemical assessments. Results. In comparison with orthodontic treatment only, the contralateral corticotomy significantly accelerated OTM. Furthermore, animals undergoing corticotomy + OTM presented with a greater number of osteoclasts on the compression side, stronger staining of the osteogenic marker on the tension side, and higher expression of an inflammatory marker than the OTM group animals. Conclusion. Our current study demonstrates that remote corticotomy effectively accelerates alveolar bone remodeling and OTM. The study enriches our understanding of the regional acceleratory phenomenon (RAP) and offers an alternative strategy for accelerating OTM to shorten the orthodontic treatment period.

Abstract:

Childhood and adolescence include periods of growth in which the pediatrician meets multiple challenges in terms of cooperation, compliance with treatment, and the patient�s family, thus constituting the pedodontic triangle. The importance of long-term patient monitoring should not be neglected, especially for those in the stage of growth and development of temporary or permanent dentition, when a real cascade of bad events can be triggered. Mobile dental appliances with the indication to be worn both day and night, less during meals and when tooth cleaning is taking place. They are used for a relatively short period as part of a wider treatment plan. The efficiency of an orthodontic appliance is appreciated by the possibilities it offers to reach the desired result in a minimum treatment time, without affecting the biological integrity of the substrate on which it operates. Ortodontic mobilisable devices used to correct dento-maxillary abnormalities, requires plates with orthodontic force, retention and anchoring. If these are used as contention devices, is needed only retention. Study group regards the selection, examination and orthodontic treatment of 46 cases at the Orthodontic Clinic of the University of Medicine and Pharmacy T�rgu Mure� between 2014-2016.The study deals with the theoretical aspects regarding biomechanics and the principles of orthodontic treatment and at the same time represents a synthetic exposure characteristics of the orthodontic devices, considering the development of new techniques. Orthodontic treatment begins in childhood, around the age of 6 years old or when the child has 4-6 milk teeth, when we already can see problems in growing of jaw and permanent teeth.

Abstract:

A variety of dental devices such as orthodontics, artificial teeth are implanted in oral cavity for long term. The implant coated with protective films, which can reduce corrosion and wear, may prevent the problems described above and extend the lifetime of implants to the benefit of the patients. Diamond-like carbon films have extreme hardness, low friction coefficients, chemical inertness, and high-corrosion resistance. Moreover, these properties make the good candidates as biocompatible coatings for dental devices. In this study, DLC films using the plasma CVD method deposited on acrylic resin and orthodontic archwires have investigated to detect the Ni release from the wires and to estimate cell growth in E-MEM immersed acrylic plates. After 6 months, the concentration of the nickel release from DLC-coated wire and Non-coated wire was 150 [ppb] and 933 [ppb], respectively. Results indicated DLC films inhibit the release of these materials, and prevent degradation of these materials in the solution.

Abstract:

Mini-screws have brought new perspectives on the prognosis of the orthodontic treatment due to their ability to provide maximum anchorage and minimum compliance from the patient. Biomaterials used for mini-implant manufacturing are stainless steel, chrome-cobalt alloy, commercially pure titanium and grade 5 titanium alloy. These materials influence the type of cellular response in the host tissue, the stability of the device and, finally, the clinical success. Recent research has met the need for clinicians to enhance the stability of these devices through a series of changes to the surface which is in direct contact with bone. This paper aims to analyze the methods used as a surface treatment for orthodontic mini-implants and to evaluate their influence on the stability of these devices. This paper is a synthesis of existing data in the literature, based on inclusion in the analysis of full-text scientific articles relevant for the chosen topic.

Abstract:

Purpose. Schizodontism is complete separation of a dental germ. It results in a twin tooth and supernumerary teeth. The treatment of transverse constriction in combination with supernumerary dental germs and impacted central incisors can pose a challenge, especially in young patients, when the number of permanent teeth is not adequate to ensure secure anchorage. The use of navigation templates based on three-dimensional X-ray images allows for precise insertion of temporary mini-implants for the acquisition of palatal distractors. In addition, templates allow for minimally invasive biopsies and osteotomies. Methods. The treatment of schizodontism, dentitio tarda, and transverse constriction is to be assessed as an interdisciplinary method by using mini-screw-assisted devices. Minimized osteotomy of impacted supernumerary teeth or dental implantation can be carried out in a one-step-procedure based on digital preplanning and prefabrication of orthodontic devices. Results. Multifunctional templates allow for early planning, preoperative fabrication, and intraoral fixation of orthodontic appliances. In the case of an adolescent patient, a sustainable, interdisciplinary treatment concept could be demonstrated that shows age-appropriate gnathological development and stable growth conditions over a follow-up period of 10 years. Conclusion. One can likely assume that multifunctional templates allow for minimally invasive one-step surgeries as an interdisciplinary tool between orofacial surgery and modern orthodontics.

ABSTRACT Aim The purpose of this case report is to present the orthodontic, surgical and restorative treatments in the case of an operated cleft lip and palate and severe maxillary deficiency in a 14-year-old female patient. Background Only orthodontic treatment could be inefficient for cleft lip and palate patients characterized with maxillary hypoplasia. Orthodontic and surgical treatment shows sufficient results, especially with severe skeletal deficiency. Case report A cleft lip and palate patient required complex multidisciplinary treatment to preserve health and restore esthetics. Dental leveling and alignment of the maxillary and mandibular teeth were provided before the surgery. Maxillary advancement and clockwise rotation of the maxillary-mandibular complex was applied by a Le Fort 1 osteotomy with two internal distraction devices. After the active treatment including orthodontic treatment and orthognathic surgery, upper full mouth ceramic restoration was applied. Conclusion This report shows the efficiency of internal distraction devices in cleft lip palate patients and exemplifies the multidisciplinary care required for such difficult cases. Clinical significance Stable improved occlusion and skeletal relations were observed after a follow-up examination period of 12 months. How to cite this article Öz AA, Özer M, Eroglu L, Özdemir OS.

Abstract:

Orthodontic appliances induce bone remodeling by acting as systems of forces and moments onto the crown of a tooth. These forces and moments should be within low physiological range to avoid resorptions. This is often realized by the use of superelastic wires or springs. For improving the design of these devices, we use the Finite Element Method (FEM) to simulate the behavior of teeth and devices. Great advantages were made in simulating the bone remodeling during the movement of a single tooth. Due to the lack of element types implementing hysteresis in the stress/strain graph, it is difficult to simulate the non-linear material properties of the superelastic wires made of NiTi-alloys. For this reason, we integrated the measurement of the devices into the calculation of the tooth movement. In this study we simulate the orthodontic long-term tooth movement of the canine retraction, using the new hybrid retraction spring.5 This spring allows a well-defined adjustment of the acting force system. The result of this study provides an example of how this approach can be used for future comparison of different orthodontic devices.

Objective: To survey the opinion of recently qualified and established orthodontists on the perceived value of their training and to identify specific areas which which were considered to be deficient, adequately covered or focussed on excessively. Design: Descriptive cross-sectional survey Setting: Online electronic questionnaire. Participants: Members of the British Orthodontic Society (BOS). Methods: An electronic questionnaire was circulated to members of the BOS focusing on dental education history, and opinions concerning orthodontic teaching generally and specific clinical and non-clinical subjects. Information was also obtained in terms of possible need for improvement, modification or removal of teaching on focused academic and clinical aspects. Results: A total of 217 responses were received from 1080 emailed invitations resulting in a response rate of 20.1%. Respondents were generally satisfied with their training both in relation to theoretical, academic and practical aspects. However, training was regarded as deficient by some respondents in respect of temporary anchorage devices (38%), bonded retainers (6%), experience with lingual appliances (47%), removable aligners (44%), inter-proximal reduction (24%) and adult orthodontics (16%), working with therapists (32%), and NHS contracts (47%) and commissioning (47%). Conclusion: The overall satisfaction of BOS members with postgraduate orthodontic training is generally high, although both recently qualified and established practitioners emphasised the need for better exposure to training in specific practical aspects and practice management within the NHS.

Abstract In order to fulfill their function, orthodontic devices must be cemented on teeth using orthodontic rings. The retention of the orthodontic ring is influenced mainly by the type of dental-ring adhesion. This study was initiated to determine possible microleakage events while using zinc phosphate cement Adhesor (Spofa Dental), conventional glass ionomer Ketac Cem (3M ESPE) and Fuji Ortho (GC) and a compomer Transbond Plus (3M Unitek). The results of the study are consistent with those reported in the literature reference, the compomer is the preferred adhesive material for cementing the orthodontic rings, compared to conventional glass ionomer cements and zinc-phosphate cement.

Abstract:

Modalities that increase the rate of tooth movement have received considerable attention, but direct comparisons between devices are rare. Here, we contrasted 2 mechanical vibratory devices designed to directly transfer vibrations into alveolar bone as a means to influence bone remodeling. To this end, 3 cells types intimately involved in modulating tooth movements—osteoblasts, periodontal ligament fibroblasts, and osteoclasts—were subjected to in vitro vibrations at bout durations prescribed by the manufacturers. As quantified by an accelerometer, vibration frequency and peak accelerations were 400% and 70% greater in the VPro5 (Propel Orthodontics) than in the AcceleDent (OrthoAccel Technologies) device. Both devices caused increased cell proliferation and gene expression in osteoblasts and fibroblasts, but the response to VPro5 treatment was greater than for the AcceleDent. In contrast, the ability to increase osteoclast activity was device independent. These data present an important first step in determining how specific cell types important for facilitating tooth movement respond to different vibration profiles. The device that engendered a higher vibration frequency and larger acceleration (VPro5) was superior in stimulating osteoblast and fibroblast cell proliferation/gene expression, although the duration of each treatment bout was 75% shorter than for the AcceleDent.

Abstract:

ABSTRACT Objective: To evaluate the effect of diameter and orthodontic loading of a screw-type implantable device on bone remodeling. Materials and Methods: Screw-shaped devices of four distinct diameters, 1.6, 2, 3, and 3.75 mm, were placed into edentulous sites in five skeletally mature beagle dogs (n = 14/dog) following premolar extraction. Using a split-mouth design, devices on one side were loaded using calibrated 2N coil springs. Epifluorescent bone labels were administered intravenous prior to sacrifice. Bone-implant sections (∼ 70 μm) were evaluated to quantify bone formation rate (BFR), and other histomorphometric variables were assessed in the implant supporting bone. Results: The mean BFR ranged from 10.93 percent per year to 38.91 percent per year. BFR in the bone adjacent to the device was lower for the loaded 1.6-mm screws when compared with the nonloaded 1.6-mm screws (P < .01) and the loaded 2.0-, 3.0-, and 3.75-mm diameter screws (P < .01). No significant differences in BFR were noted, regardless of loading condition, between the 2.0-, 3.0-, and 3.75-mm diameter screws. Conclusions: We detected a dramatic reduction in bone remodeling. Although orthodontic loading of 2N did not alter bone remodeling associated with screws with a 2.0-mm diameter or larger, it did decrease bone remodeling adjacent to a loaded 1.6-mm screw. The long-term effect of this diminished remodeling should be further investigated.

Class II represents a considerable part of orthodontic problems to be treated in dental clinics. To correct this malocclusion, there are currently several forms of treatment. Among the functional orthopedic devices, the Herbst device has stood out due to its efficiency and practicality for being fixed and not requiring the collaboration of the patient. The purpose of this article is to present, through a clinical case report, the treatment of class II malocclusion with a modified Herbst appliance with a lower acrylic splint. The female patient initially had 11 years and 11 months, permanent dentition, mandibular retrusion and atresia of the arches. Initially, a maxillary circuit breaker and lower expander were used, followed by the Herbst appliance and finished with fixed orthodontics. At the end of the treatment, the modified Herbst appliance proved to be effective, providing a class I molar relationship, improving the patient’s profile and decreasing the space between the resting lips.

Abstract:

The usage of the portable electronic devices such as the smartphones and handheld tablets has increased over the years, and this is true in the health-care industry also. This is because of the development of various patient management softwares. The use of apps to manage, educate, and inform patient is not uncommon among orthodontists nowadays. The aim of this article was to review the various apps available on the Google Play Store and iOS Apple Store for orthodontists and patients. Four smartphones using orthodontically relevant keywords such as orthodontics, orthodontists, and braces were searched and reviewed in detail. Out of the 354 orthodontically relevant apps available in both Android and Apple operating systems, the apps could be categorized as orthodontist-related apps or patient-related apps. Under these categories they could be further classified as practice managements apps, patient education apps, model analysis apps, tooth material calculators, patient reminder apps, etc.

Abstract:

A brief description of the uses and clinical applications of synthetic cyanoacrylate polymer adhesive/glues that have been cleared and/or approved as medical devices by FDA since the Medical Device Amendments of 1976 were enacted. This includes cyanoacrylate Class I devices (Exempt and not Exempt devices), Class II cyanoacrylate devices such as Dental Cements and Orthodontic Bracket Adhesives, and Class III (PMA) devices such as Dermabond™, Indermil™ Tissue Adhesive, and Trufill® n-Butyl Cyanoacrylate Embolic Agent. By citing an example of recently FDA approved Class III (PMA) devices in the Cyanoacrylate technology, the author provides a brief discussion of the FDA approval process of medical devices. It includes the FDA issues regarding the published guidance document for "Cyanoacrylate Topical Tissue Adhesives" that will provide guidance to regulatory personnel and manufacturers in the preparation of IDE applications and in the development of valid scientific evidence to support PMA applications for cyanocrylate tissue adhesives intended for topical approximation of skin and others. Also, the author provides a short regulatory description of US FDA; under what laws its operates, how FDA evaluates new devices for marketing, and how the device regulatory system works, for example, Class I, Class II, and Class III cyanoacrylate medical devices.
