Com o aperfeiçoamento das técnicas cirúrgicas, os resultados dos tratamentos mostram-se cada vez mais previsíveis e estáveis, contudo a literatura mostra muitas variáveis que podem influenciar na estabilidade do tratamento ortodôntico-cirúrgico. Além disso, à medida que os pacientes estão obtendo um acesso cada vez maior a esta opção terapêutica para as maloclusões do tipo Classe III, julgamos importante avaliar sua estabilidade em 20 pacientes, sendo 11 do sexo masculino e 9 do feminino, com média de idade de 26 anos e 1 mês, submetidos inicialmente ao tratamento ortodôntico para descompensação dentária, com o subseqüente tratamento cirúrgico combinado de maxila e mandíbula, utilizando fixação interna rígida, e finalização ortodôntica. As telerradiografias, obtidas em norma lateral, pertencentes ao arquivo do CEDEFACE, realizaram-se antes da cirurgia, no pós-operatório imediato e no mínimo 6 meses após a cirurgia, com uma média de período pós-cirúrgico tardio de 27 meses. Avaliaram-se dezenove grandezas cefalométricas, e os resultados foram analisados estatisticamente. A cirurgia de avanço maxilar mostrou-se um procedimento muito estável. A estabilidade do recuo mandibular ficou comprometida no sentido horizontal, com recidiva de 37,75% no ponto B, e de 45,85% no ponto Pg, devido ao giro anti-horário da mandíbula entre os períodos pós-operatórios, ocorrido pela melhor intercuspidação pós-cirúrgica e adaptação muscular do paciente à nova posição esquelética, provocando um reposicionamento mais anterior da mandíbula. Os resultados apresentaram as mesmas tendências para ambos os sexos. Concluímos que no tratamento cirúrgico combinado da maloclusão do tipo Classe III, o procedimento realizado na maxila mostrou-se muito estável, e na mandíbula a estabilidade ficou comprometida no sentido horizontal, devido ao seu giro anti-horário; não foram evidenciadas diferenças estatísticas na estabilidade cirúrgica entre os sexos / Abstract: Amongst the skeletal deformities requiring orthosurgical treatment are the Class III malocclusions, which usually occur due to either maxillary retrusion, mandibular protrusion or a combination of both. As a result, both facial harmonyand stomatognathic function are impaired by such characteristics. As the surgicaltechniques improve, the treatment outcomes are found to be increasinglypredictable and stable. Many variables regarding such a malocclusion are reported by the literature as factors influencing the stability of the orthosurgical treatment. Also, as the patients have been obtaining more access to orthodontic treatment, particularly involving Class III malocclusions, we believe it is important to assess the surgical stabilisation. Twenty skeletal Class III patients (11 males and 9females) with a mean age of 22.1 years had been initially submitted to orthodontic treatment for dental decompansation so that maxillo-mandibular surgical treatment, using rigid internal fixation, could be performed later on, followed by a postsurgical orthodontic finishing. Pre and postsurgical lateral teleradiographs were obtained from the CEDEFACE¿s archives. Also, postsurgical radiographs taken at least 6 months after the surgery were used, with a mean late postsurgical period of 27 months. Nineteen cephalometric measurements were evaluated, and the results were statistically analysed. Maxillary advancement was thought to be a stable procedure. However, the stability of the mandibular setback was impaired in relation to the horizontal plane as evidenced by 37.75% and 45.85% of relapse for points B and Pg, respectively. The increased anterior repositioning of the mandible was due to its counterclockwise rotation, which had occurred during the postsurgical period as a result of the increased intercuspation following surgery. Additionally, the patient¿s muscular adjustment to the new skeletal positioning played an important role. The cephalometric measurements found for males showed similar trends in comparison with those found for females. Regarding the combined surgical treatment for Class III malocclusions, we can conclude that the procedure carried out on the maxilla was stable, although the mandibular stability was impaired in relation to the horizontal plane due to the counterclockwise rotation; no statistical differences in the surgical stability were observed between males and females / Doutorado / Ortodontia / Doutor em Radiologia Odontológica
