ABSTRACT

Abstract Introduction There is no consensus about the immediate and latte follow-up effects of maxillary protraction in cleft lip and palate patients. Objective To evaluate the stability of Class III early treatment in cleft lip and palate patients through maxillary expansion and protraction. Material and method The sample consists in three lateral cephalometric radiographs of 28 patients (mean pre-treatment age of 6.7±1.8 years) who presented cleft lip and palate and were treated with maxillary expansion and Petit facial mask. The angular (SNA, SNB, ANB, SN.GoGn, FMA, Z Angle) and linear (overjet, Co-A, Co-Gn, Nperp-A, Nperp-Pg, AO-BO) cephalometric measures were evaluated through the Dolphin® software, in three moments: T0 (initial), T1 (after treatment), and T2 (follow-up). Data were submitted to the analysis of variance (ANOVA) and Tukey-Kramer test. The correlation between cephalometric measures and patient's age was determined by Pearson's chi-squared test. Result The SNA, ANB, and AO-BO measures increased considerably (p<0.05), and they did not present any differences compared to the initial ones after the follow-up time. The overjet measure increased (p<0.05) after treatment and, even with its decrease at the follow-up time, it was still higher than at the beginning (p<0.05). The Z angle showed improvement with treatment and remained stable at the follow-up time. Conclusion After treatment (maxillary expansion associated with protraction), there was a skeletal pattern improvement. During the follow-up period, those alterations decreased to a measure close to the beginning. There was an improvement in the dental pattern and facial profile that continued in the follow-up period.


Resumo Introdução Não há consenso sobre os efeitos imediatos e tardios da protração maxilar em pacientes com fissura lábio palatal. Objetivo avaliar a estabilidade do tratamento precoce da Classe III em pacientes com fissura labiopalatina por meio da expansão e protração maxilar. Material e método A amostra consistiu de 28 pacientes com fissura lábio palatal com (média de idade pré tratamento de 6.7±1.8) com fissura lábio palatal transforame unilateral, tratados com disjuntor maxilar e com máscara facial de Petit. Por meio de análise em telerradiografias laterais as grandezas angulares (SNA, SNB, ANB, SN.GoGn, FMA, Ângulo Z) e lineares (overjet, Co-A, Co-Gn, Nperp-A, Nperp-Pg, AO-BO) foram avaliadas, com o software Dolphin®, nos tempos: inicial (T0), após o tratamento (T1) e acompanhamento de 2 a 6 anos (T2). Os dados foram submetidos à ANOVA e teste Tukey-Kramer. A correlação entre as grandezas cefalométricas e a idade do paciente foi determinada pelo teste de Pearson. Todas as análises foram realizadas com nível de significância de 5%. Resultado SNA, ANB e AO-BO aumentaram significativamente (p<0,05) e após o período de acompanhamento voltaram a ser semelhantes às iniciais (p>0,05). O overjet aumentou significativamente após o tratamento e mesmo tendo diminuído com o tempo, ainda se apresentava maior quando comparado ao momento inicial (p<0,05). O ângulo Z apresentou melhora com o tratamento e se manteve estável no período de acompanhamento (p<0,05). Conclusão após o tratamento (disjunção associada à protração maxilar) houve melhora do padrão esquelético. No período de acompanhamento, verificou-se que essas melhoras voltaram a medidas próximas das iniciais. Houve melhora no padrão dentário e no perfil facial que se manteve no período de controle.
