Utilizou-se 60 telerradiogafias em norma lateral, tomadas no início e no final do tratamento ortodôntico corretivo de 30 pacientes (22 femininos e 8 masculinos) entre 10 e 17 anos, com má oclusão de Classe II, divisão 1 e de Classe I, com extração dos primeiros pré-molares superiores. Além das grandezas 1.NA, 1-NA, 1.PP e 1-A, distâncias lineares horizontais e verticais foram mensuradas utilizando como referência uma linha horizontal 7o abaixo do plano SN e a sua perpendicular. Sendo normalmente distribuídos, todos os dados foram mensurados duas vezes, cujos valores médios foram submetidos ao teste t emparelhado, testes de correlação e de regressão linear. Em média, o ponto A retraiu 0,71 mm e deslocou para baixo 2,38 mm, acompanhando uma retração do ápice radicular de 1,03 mm e da borda incisal de 4,13 mm e uma extrusão dentária de 2,35 mm. Houve correlação positiva entre a retração do ponto A e do ápice radicular (r=0,75; a<0,0001) e da borda incisal (r=0,70; a<0,0001), demonstrando um padrão previsível no comportamento ântero-posterior. Concluiu-se que o ponto A retraiu e deslocou para baixo acompanhando o dente, demonstrando padrão previsível no sentido ântero-posterior. / It was aimed to evaluate the effect of retraction of anterior teeth on the point A antero-posteriorly and vertically, as well as the correlation and the predictability of the behavior of these structures. Sixty telerradiographs in lateral norm were taken, at the beginning and the end of corrective orthodontic treatment, from thirty patient (22 female and 8 male) aging from 10 to 17 years, with Class II, division 1 and Class I malocclusion and underwent maxillary first premolars extractions. Besides the variables 1.NA, 1-NA, U1/PP and U1?Avert, horizontal and vertical linear measurements were made in relation to a horizontal reference line constructed from the S-N plane minus 7o and its perpendicular. As distributed normally, all the data were measured twice, and the mean values were submitted to paired t test, linear correlation and regression tests. In average, point A retracted 0,71 mm and moved 2,38 mm downwardly, following 1,03 mm of root apex and 4,13 mm of incisal edge retraction, and 2,35 mm of tooth extrusion. The retraction of point A was positively correlated with root apex (r=0,75; p<0,0001) and with incisal edge retraction (r=0,70; p<0,0001), showing a predictable antero-posterior behavior. It was concluded that point A retracted and moved downwardly following the tooth, and the retraction of point A in relation to the anterior tooth showed predictable pattern.

Prevalence of Temporomandibular Dysfunction in the Class II Division I Untreated Patient and the Class II Division I Orthodontically Treated Patient with Premolar ExtractionsBolon, Rebecca Anne January 1990 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Orthodontics has been suggested as a form of treatment for temporomandibular (TM) disorders, while at the same time orthodontic treatment accompanied by premolar extraction has been blamed for producing iatrogenic internal derangement of the TM joint. Signs and symptoms of TM disorders were evaluated by a clinical history questionnaire and a thorough clinical examination. The clinical examination entailed TMJ manipulation, palpation of muscles and TM joints, and recording the active range of motion. The 45 patients in each pre-treatment and post-treatment group were obtained from the Orthodontic Clinic at the Indiana University School of Dentistry. With the exception of age, there was no statistically significant difference between the two groups.

Avaliação da correlação da recidiva da sobressaliência e da sobremordida com a recidiva do apinhamento anterior em casos tratados com extrações / Evaluation of the correlation of the overjet and overbite relapse with the relapse of anterior crowding in extraction casesOliveira, Ricardo Cesar Gobbi de 02 March 2011 (has links)
Tendo em vista a imprevisibilidade da estabilidade oclusal pós correção ortodôntica, este estudo objetivou correlacionar a recidiva da sobremordida e da sobressaliência com a recidiva do apinhamento ântero-superior e ântero-inferior, em casos com má oclusão de Classe I e Classe II de Angle, tratados ortodonticamente com extração de 4 pré-molares, tratados pela técnica Edgewise. Para isso, foram selecionados 40 pacientes (20 do gênero feminino e 20 do gênero masculino), 25 pacientes portadores de má oclusão de Classe I e 15 de Classe II de Angle, com idade média inicial de 13,01 anos, que foram tratados por um tempo médio de 2,15 anos, e avaliados na fase pós-contenção após um período médio de 5,43 anos. Todos os pacientes apresentavam pelo menos 3 mm de sobremordida e 4mm de sobressaliência ao início do tratamento ortodôntico. Foram utilizados os modelos de gesso das fases do início do tratamento (T1), final de tratamento (T2) e da fase pós-contenção, em média 5 anos após o término do tratamento (T3) de todos os casos selecionados para que fossem quantificadas as recidivas dessas duas variáveis, assim como a recidiva do apinhamento anterior. Utilizou-se a análise de variância a um critério de seleção, e em caso de resultado significante, o teste de Tukey, para comparação intragrupos dos 3 tempos avaliados. Para verificação da presença de correlação entre a recidiva da sobressaliência e da sobremordida, com o apinhamento anterior, utilizou-se o teste de correlação de Pearson. A comparação intergrupos foi realizada por meio do teste t independente. Os resultados mostraram que houve uma correção significante do trespasse horizontal, vertical e apinhamento com o tratamento. Não houve uma recidiva significante do trespasse horizontal, vertical e do apinhamento ântero-superior no período pós-contenção, ao contrário do apinhamento ântero-inferior, que apresentou uma recidiva significante. Houve correlação significante da recidiva do trespasse horizontal com a recidiva do trespasse vertical. Não houve correlação significante entre a recidiva do trespasse horizontal e a recidiva do apinhamento anterior. Não houve correlação entre a recidiva do trespasse vertical e a recidiva do apinhamento anterior, assim como também não houve correlação entre a recidiva do apinhamento ântero-inferior e ântero-superior. Houve diferença intergrupos apenas para o apinhamento ântero-inferior ao início do tratamento, que foi maior no grupo Classe I, que apresentou também uma maior correção com o tratamento e um maior apinhamento na fase pós-contenção. / Due to the unpredictability of the occlusal stability after orthodontic correction, this study aimed to correlate the relapse of overbite and overjet with the relapse of maxillary and mandibular anterior crowding, in cases of Class I and Class II malocclusions, treated orthodontically with four premolars extraction and Edgewise technique. For this, 40 patients were selected (20 females and 20 males), 25 patients with Class I malocclusion and 15 with Class II, with initial age of 13.01 years, which were treated for a mean period of 2.15 years, and evaluated postretention after a mean period of 5.43 years. All patients had at least 3mm of overbite and 4mm of overjet at the beginning of orthodontic treatment. The dental casts from pretreatment (T1), posttreatment (T2) and postretention, on average 5 years after completion of treatment (T3), were used. It was used the one-way ANOVA, and in case of a significant result, Tukey\'s tests were used for intragroup comparison of the three times evaluated. To verify the presence of correlation between the relapse of overjet and overbite, with the relapse of anterior crowding, the Pearsons correlation test was used. Intergroup comparison was performed with independent t tests. The results showed a significant correction of the overjet, overbite and crowding during treatment. There was not a significant postretention relapse of overjet, overbite and crowding of the maxillary anterior segment, unlike the mandibular anterior crowding, which presented a significant relapse. There was a significant correlation of relapse of the overjet with the relapse of the overbite. No significant correlation between relapse of overjet and relapse of anterior crowding. There was no correlation between relapse of the overbite and relapse of anterior crowding, and there was also no correlation between mandibular anterior crowding relapse and maxillary anterior crowding relapse. There were differences between groups only for the mandibular crowding at pretreatment, which was higher in Class I, which also showed a larger correction with treatment and greater relapse of this crowding in the postretention.
