Abordagem cirúrgico-ortodôntica de dentes não irrompidos

The understanding of the etiology and the determination of the position of the unerupted teeth turn safer the surgical planning of the cases. By the number of techniques proposed to the orthodontic traction of unerupted teeth, the particularities of each one must be understood to select the most appropriate technique and control the unwanted effects. Based on literature and comparing results obtained with the most used surgical techniques, this article describes different ways of accesses for the orthodontic traction of unerupted teeth, detailing interest aspects to the orthodontist. The authors concluded that the surgical techniques present particularities worthy of the orthodontists´ knowledge - once they will be executed in agreement with the preference or experience of the involved professionals.

Parâmetros de força ideal aplicada aos principais movimenetos ortodônticos

The orthodontic movement is a result of the system of forces application and it depends on the response of periodontal tissues to this system. The forces must have a magnitude considered ideal, to has maximum response of tissue without pain or root resorption, and keep the health of the periodontal ligament, during all the tooth movement. Therefore, it seems adequate by means of an available literature to estimate parameters of ideal force, for different types of movements; with intention of assisting the orthodontists in optimum control of the tooth movement and thus to diminish the possibility to generate deleterious effects.

Confecção e montagem do set-up ortodôntico

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.

Considerações acerca do preparo ortodôntico direcionado à cirurgia ortognática

This work aims at contributing to increase and improve the communication between orthodontists and maxillofacial surgeons, reviewing and discussing the principles of diagnosis and orthodontic movement specific to patients with surgical indication. It describes the elective points in the conduct of the orthodontist so that their decisions could lead to an individualized and appropriate planning, striving for excellence in terms of outcomes for the surgical-orthodontic treatment of dentofacial discrepancies.

Spectrophotometric evaluation of dental bleaching under orthodontic bracket in enamel and dentin

Aware of the diffusion capacity of bleaching in the dental tissues, many orthodontists are subjecting their patients to dental bleaching during orthodontic treatment for esthetic purposes or to anticipate the exchange of esthetic restorations after the orthodontic treatment. For this purpose specific products have been developed in pre-loaded whitening trays designed to fit over and around brackets and wires, with clinical efficacy proven. Objective: The objective of this study was to evaluate, through spectrophotometric reflectance, the effectiveness of dental bleaching under orthodontic bracket. Material and Methods: Thirty-two bovine incisors crown blocks of 8 mm x 8 mm height lengths were used. Staining of tooth blocks with black tea was performed for six days. They were distributed randomly into 4 groups (1-home bleaching with bracket, 2- home bleaching without bracket, 3- office bleaching with bracket, 4 office bleaching without bracket). The color evaluation was performed (CIE L * a * b *) using color reflectance spectrophotometer. Metal brackets were bonded in groups 1 and 3. The groups 1 and 2 samples were subjected to the carbamide peroxide at 15%, 4 hours daily for 21 days. Groups 3 and 4 were subjected to 3 in-office bleaching treatment sessions, hydrogen peroxide 38%. After removal of the brackets, the second color evaluation was performed in tooth block, difference between the area under the bracket and around it, and after 7 days to verified color stability. Data analysis was performed using the paired t-test and two-way variance analysis and Tukey’s. Results: The home bleaching technique proved to be more effective compared to the office bleaching. There was a significant difference between the margin and center color values of the specimens that were subjected to bracket bonding. Conclusions: The bracket bond presence affected the effectiveness of both the home and office bleaching treatments.

Avaliação da agradabilidade facial de pacientes portadores de padrão facial II e III por ortodontistas e leigos

Aim: compare the evaluation of orthodontics and lay people on facial attractiveness of pattern II and III subjects. Methodology: thirty orthodontists and 30 laymen judged a profile facial photos of 64 subjects standard II and III (34 standard II e 30 standard III), making as visual analogical scale (VAS) with 10 cm. Results: after evaluation, the results were submitted to a statistics analysis (Mann- Whitney test) showed that the groups of evaluators orthodontists and lay people differed in their assessments, and these differences are statistically significant. Conclusions: the laymen was more rigorous than orthodontics, and both considered the female pattern III more agradable.

O momento oportuno para a abordagem ortodontica no tratamento da classe II

Because it still brings polemic among the professionals, it was mention once more, in this literature review, the theme that aims to define the appropriate timing to approach the bad occlusions of Class II, and also when it would the right opportunity to treat them, in way that would convey to the patient consistent, stable results in a long term. These are important aspects to be taken into consideration by orthodontists, either by those who defend the early treatment or by those who defend the late treatment. Therefore, the present study aims to aid the clarification of daily doubts regarding this aspect.
