Angle Class III malocclusion has been a challenge for researchers concerning diagnosis, prognosis and treatment. It has a prevalence of 5% in the Brazilian population, and may have a genetic or environmental etiology. This malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis. Considering these topics, the aim of this study was to describe and discuss a clinical case with functional Class III malocclusion treated by a two-stage approach (interceptive and corrective), with a long-term follow-up. In this case, the patient was treated with a chincup and an Eschler arch, used simultaneously during 14 months, followed by corrective orthodontics. It should be noticed that, in this case, initial diagnosis at the centric relation allowed visualizing the anterior teeth in an edge-to-edge relationship, thereby favoring the prognosis. After completion of the treatment, the patient was followed for a 10-year period, and stability was observed. The clinical treatment results showed that it is possible to achieve favorable outcomes with early management in functional Class III malocclusion patients.

Algumas más oclusões exigem do ortodontista capacidade de diagnóstico para decidir pela melhor maneira de tratar o paciente. O objetivo dos autores deste artigo foi apresentar casos clínicos e discutir alguns elementos de diagnóstico utilizados na elaboração do plano de tratamento, auxiliando na decisão de extrair dentes. Foi dada ênfase em cada elemento de diagnóstico: aspectos relacionados à cooperação, discrepância de modelo, discrepância cefalométrica e perfil facial, idade esquelética (crescimento) e relações anteroposteriores, assimetrias dentárias, padrão facial e patologias. Sugere-se que a associação dos aspectos citados é importante para a decisão correta. Todavia, algumas vezes, uma característica, por si só, pode definir o plano de tratamento.; Certain malocclusions require orthodontists to be capable of establishing a diagnosis in order to determine the best approach to treatment. The purpose of this article was to present clinical cases and discuss some diagnostic elements used in drawing up a treatment plan to support tooth extraction. All diagnostic elements have been highlighted: Issues concerning compliance, model discrepancy, cephalometric discrepancy and facial profile, skeletal age (growth) and anteroposterior relationships...

A mordida aberta é uma anomalia com características distintas que, além da complexidade dos múltiplos fatores etiológicos, traz consequências estéticas e funcionais. Muitas alternativas têm sido utilizadas em seu tratamento, entre elas a grade palatina, forças ortopédicas, ajuste oclusal, camuflagem com ou sem exodontias, mini-implantes ou miniplacas e cirurgia ortognática. O diagnóstico preciso e a determinação da etiologia permitem estabelecer os objetivos e o plano de tratamento ideal para essa má oclusão. O presente relato descreve o tratamento de uma má oclusão Classe I de Angle, com padrão esquelético de Classe II e mordida aberta anterior, realizado em duas fases e que foi apresentado à diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO), representando a categoria 2, como parte dos requisitos para a obtenção do título de Diplomado pelo BBO.; Open bite is an anomaly with distinct characteristics which, in addition to involving complex, multiple etiologic factors, entails aesthetic and functional consequences.

A estabilidade pós-tratamento sempre foi um assunto delicado da ortodontia. A maioria dos pacientes e até mesmo os ortodontistas, julgam o sucesso do tratamento ortodôntico pela estabilidade dos resultados em longo prazo. Por este motivo a literatura é repleta de estudos acerca deste assunto, principalmente da recidiva do apinhamento ântero -inferior. Já o interesse pelo apinhamento ânterosuperior e sua recidiva é crescente por conta de uma maior preocupação com a estética do sorriso. Desta forma, o propósito deste estudo é comparar a recidiva do apinhamento ântero-superior em pacientes com má oclusão de Classe I e Classe II de Angle. A amostra consiste em 70 pacientes divididos em 3 grupos. O Grupo 1 apresenta 30 pacientes (12 do gênero masculino e 18 do gênero feminino) com má oclusão de Classe I, idade média inicial de 13,16 anos e tratados com extrações dos 4 primeiros pré -molares. O Grupo 2 apresenta 20 pacientes (11 do gênero masculino e 9 do gênero feminino) com má oclusão de Classe II divisão 1, idade média inicial de 12,95 anos e também tratados com extrações dos 4 primeiros pré-molares. O Grupo 3 apresenta 20 pacientes (11 do gênero masculino e 9 do gênero feminino) com má oclusão de Classe II divisão 1...

Diagnosis and planning stages are critical to the success of orthodontic treatment, in which the orthodontist should have many elements that contribute to the most appropriate decision-making. The orthodontic set-up is an important resource in the planning of corrective orthodontics therapy. It consists of the repositioning of the teeth previously removed from the study dental casts and reassembled on its remaining basis. When properly made, the set-up allows a three-dimensional preview of problems and limitations of the case, assisting in decision-making regarding tooth extractions in cases with problems of space, amount of anchorage loss extent and type of tooth movement, discrepancy of dental arch perimeter, discrepancy of inter-arch tooth volume, among others, indicating the best option for treatment. This paper outlines the most important steps for its confection, an evaluation system and its application in the preparation of orthodontic treatment planning.; O diagnóstico e o planejamento constituem etapas fundamentais para o sucesso do tratamento ortodôntico, nas quais o ortodontista deve ter inúmeros elementos que contribuem na tomada das decisões mais acertadas.

Contemporary orthodontics has sought, beyond the esthetic, occlusal and functional goals, treatments even faster and with less visits to the orthodontist — especially in patients that require dental extractions in which the generated space becomes a nuisance. The segmented arch technic (SAT), by the use of a "T" loop spring, has provided such results within these requirements. Therefore, this study aimed to appraise and demonstrate the confection, activation and biomechanical control of "T" loop spring, in the group with high anchorage necessity (group A), for retraction of anterior teeth; as well as to present a case report, with high anterior retraction necessity, treated with "T" loop spring.; A Ortodontia contemporânea tem buscado, além dos objetivos estéticos, oclusais e funcionais, tratamentos cada vez mais rápidos e com menor número de consultas ao ortodontista — principalmente em pacientes com necessidade de exodontias, cujo espaço deixado certamente torna-se um incômodo. A técnica do arco segmentado (TAS), por meio do uso da mola "T", tem proporcionado tais resultados dentro dessas exigências. Sendo assim, o objetivo do presente trabalho foi conceituar e demonstrar a ativação e forma de controle biomecânico da mola "T"...

OBJECTIVE: The aims of this study were to compare the prevalence of temporomandibular disorders (TMD) in individuals submitted to either orthodontic or ortho-surgical Class III malocclusion treatment and to assess the influence of occlusal aspects on TMD severity. MATERIAL AND METHODS: The sample consisted of 50 individuals divided into two groups, according to the type of treatment (orthodontic or orthodontic with orthognathic surgery). The presence of signs and symptoms of TMD was evaluated by an anamnestic questionnaire and a clinical examination, including TMJ and muscle palpation, active mandibular range of motion, joint noises and occlusal examination. RESULTS: Based on the anamnestic questionnaire, 48% had no TMD, 42% had mild TMD and 10% had moderate TMD. The presence and severity of TMD did not show any relationship with the type of orthodontic treatment (p>0.05). The chi-square test showed a positive association (p<0.05) between TMD and non-working side occlusal interferences. CONCLUSION: Based on the methodology used and the results obtained, it may be concluded that Class III orthodontic treatment was not associated with the presence of TMD signs and symptoms and the non-working side contacts can be occlusal factors of risk. There was no significant difference in TMD prevalence between the studied groups (orthodontically treated patients and patients treated with orthodontics followed by orthognathic surgery).

The facial growth of Class III malocclusion worsens with age, in this case, the early orthopedic treatment, providing facial balance, modifying the maxillofacial growth and development. A 7.6-year old boy presented with Class III malocclusion associated with anterior crossbite; the mandible was shifted to the right and the maxilla had a transversal deficiency. Rapid maxillary expansion followed by facemask therapy was performed, to correct the anteroposterior relationship and improve the facial profile. The patient was followed for a 15-year period, after completion of the treatment, and stability was observed. Growing patients should be monitored following their treatment, so as to prevent malocclusion relapse.

This article reports the orthodontic treatment of a 14 years and 2 months old female patient, presenting both anterior and posterior unilateral left crossbite, related to a transverse atrophy of the maxilla and a severe negative tooth-arch discrepancy in the upper arch. A maxillary expansion with a modified Haas appliance was the first therapeutic attempt. Then, fixed appliances were used in both arches, and the second left premolar was extracted. The space for the upper left lateral incisor was achieved with compressed springs and tooth movement was accomplished with double archwires. The final result showed a good intercuspation, considering that the left molar relation remained as a Class II, which demanded special occlusal adjustments. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics, representing category 5, as a partial requirement for the BBO certificate.

OBJECTIVE: General dentist orthodontic practice is a controversial issue and this paper aims to analyze it comparing foreign laws to Brazilian Legal System. METHODS: Regulations and scientific texts concerning orthodontic practice by general dentists, in Portuguese or English language, were sought. RESULTS AND CONCLUSION: Portugal clearly forbids general dentist orthodontic practice; United States of America do not clearly forbid general dentist orthodontic practice, but do regulate and promote campaigns to encourage public to seek specialist service; in Australia and England, corrective orthodontics are offered both by orthodontists and general dentists; it was not possible to evaluate how orthodontic services are provided in Eastern Europe; and the fact that general dentists are forbidden to practice corrective orthodontics in Brazilian Legal System is compatible to other countries policy.

This study aims at reporting the clinical case of a patient with Class III skeletal malocclusion with severe maxillary deficiency, producing a reduced midface associated with severe mandibular prognathism. The pre-surgical orthodontic preparation was composed mainly by dentoalveolar expansion and repositioning of the incisors in the lower arch. Then, a combined maxillary and mandibular orthognathic surgery was performed. The treatment objectives were achieved, with significant improvement in facial esthetics and occlusion, followed by post-treatment stability. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements for obtaining the title of Diplomate by BBO.

OBJECTIVE: The purpose of this study was to evaluate the force delivered by different superlastic nickel-titanium wires during vertical displacement, in order to determine whether their stress release meets the criteria for constant and light forces that are usually accredited to these archwires. METHOD: Ten samples of 6 brands of 0.016-in archwires (Ormco, GAC, Morelli, TP, American Orthodontics e Rocky Mountain) were tested in a complete metal model using Dynalock brackets (3M Unitek™). In the canine position, there was a sliding bracket connected to a pole. This set was related to a load cell of 0.5 kg attached to a universal testing machine (Autograph AG-199kNG, Shimadzu). The crosshead speed was 0.5 mm/min and the maximum displacement was 1.0 mm. The model was submerged in temperature-controlled water. The results were analyzed by ANOVA (p < 0.05), using the software SAS System 8.02, Cry, NC, USA. RESULTS: The TP archwire had the lowest force throughout the test, although the final force was high (277.91 g). The Rocky Mountain archwire had the highest force release (455.41 g). CONCLUSION: The different brands of wires tested in this study failed in delivering low and constant forces as expected from superlastic nickel-titanium wires. The forces were extremely heavy for a vertical tooth movement.

OBJECTIVE: The purpose of this study was to cephalometrically compare the skeletal and dentoalveolar effects in the treatment of Class II malocclusion with Pendulum and Jones jig appliances, followed by fixed corrective orthodontics, and to compare such effects to a control group. METHODS: The sample was divided into three groups. Group 1: 18 patients treated with Pendulum, Group 2: 25 patients treated with Jones jig, and Group 3: 19 young subjects with untreated Class II malocclusions and initial mean age of 12.88 years. The chi-square test was applied to assess severity and gender distribution. Groups 1 and 2 were compared to the control group by means of the one-way ANOVA and Tukey tests in order to differentiate treatment changes from those occurred by craniofacial growth. RESULTS: There were no significant changes among the three groups with regard to the components of the maxilla and the mandible, maxillomandibular relationship, cephalometric and tegumental pattern. Buccal tipping of mandibular incisors was significantly greater in the experimental groups and increased mesial angulation of the maxillary second molars was found in the Jones jig group. In the experimental groups, dental relationship, overbite and overjet were corrected. CONCLUSION: It can be stated that the distalization achieved its purpose of correcting the Class II.

INTRODUCTION: Angle's Class III malocclusion is a dental discrepancy in a sagittal view that may appear or not with an important skeletal discrepancy. Facial esthetics may be affected by this skeletal discrepancy and it is one of the most common complaints of patients who seek orthodontic treatment. Class III treatment, in adults, may be done by compensatory tooth movement, in simple cases, or through an association between orthodontics and orthognathic surgery, in more severe cases. OBJECTIVE: This article describes a non-extraction compensatory Class III treatment case, applying the Tweed-Merrifield mechanical principles with headgear (J-Hook) in the mandibular arch. This case was presented at the V Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR) Meeting, it was evaluated by members of Brazilian Board of Orthodontics and obtained third place in the general classification.
