Abstract
- OBJECTIVE: The present study assessed the maxillary dental arch changes produced by surgically assisted rapid maxillary expansion (SARME). METHODS: Dental casts from 18 patients (mean age of 23.3 years) were obtained at treatment onset (T1), three months after SARME (T2) and 6 months after expansion (T3). The casts were scanned in a 3D scanner (D-250, 3Shape, Copenhagen, Denmark). Maxillary dental arch width, dental crown tipping and height were measured and assessed by ANOVA and Tukey's test. RESULTS: Increased transversal widths from T1 and T2 and the maintenance of these values from T2 and T3 were observed. Buccal teeth tipping also showed statistically significant differences, with an increase in all teeth from T1 to T2 and a decrease from T2 to T3. No statistically significant difference was found for dental crown height, except for left first and second molars, although clinically irrelevant. CONCLUSION: SARME proved to be an effective and stable procedure, with minimum periodontal hazards. OBJETIVOS: o presente estudo teve o objetivo de avaliar as alterações dentárias e periodontais decorrentes da Expansão Rápida da Maxila Assistida Cirurgicamente (ERMAC). MÉTODOS: foram obtidos os modelos de gesso de 18 pacientes (média de idade de 23,3 anos), ao início (T1), 3 meses após a ERMAC (T2) e 6 meses após a expansão (T3). Os modelos foram digitalizados (Scanner 3D 3Shape D-250) e mensuraram-se as distâncias transversais, bem como a inclinação e a altura da coroa clínica dos dentes posteriores. Para análise dos resultados, aplicou-se a análise de Variância e o teste de Tukey. RESULTADOS: nas distâncias transversais, observou-se um aumento de T1 para T2 e uma manutenção de T2 para T3. As inclinações dentárias demonstraram diferenças estatisticamente significativas em alguns dentes; porém, numericamente tenderam a um aumento de T1 para T2 e a uma diminuição de T2 para T3. Não se observou diferença estatisticamente significativa na altura da coroa clínica, exceto nos primeiros e segundos molares do lado esquerdo, porém, clinicamente irrelevante. CONCLUSÕES: a ERMAC demonstrou ser um procedimento efetivo e estável, com mínima repercussão periodontal.
