Previous issue date: 2014-01-20 / The objectives of this study is to conduct a systematic review to evaluate the accuracy of computer-aided design and computer-aided manufacturing planning in orthognathic surgery, to determine the quality of the current literature and the need for new methods on this subject . A systematic literature search was performed in PubMed, EMBASE, Cochrane Library, LILACS and SciELO. The gray literature was investigated in Google Scholar and in the annals of the most important conferences of Oral and Maxillofacial Surgery. The papers found passed for a selection criteria and eligibility by two authors independently and blindly. After the selection of eligible studies, it was made a manual search in the references of the included papers and then data extraction and analysis of quality were performed. By searching in the databases 350 studies were found. So, 33 were selected for full reading and six were included in the study. Through the gray literature search, four papers were selected for full reading and only one was included. From the manual search one study was included. Thus, eight studies were included in this systematic review. The level of agreement among the authors for studies selection was substancial (kappa= 0.767) and studies eligibility was considered excellent (kappa= 0.863). The accuracy in computer-aided design and computer-aided manufacturing planning in orthognathic surgery in the translation were less than 1.2 mm in the maxilla (vertical) and less than 1.1 mm in the mandible (sagittal), and in the rotations were less than 1.5? in the maxilla (pitch) and less than 1.8? in the mandible (pitch). Two studies showed a medium potential for risk of bias and six studies showed a high potential for risk of bias. The computer-aided design and computer-aided manufacturing planning in orthognathic surgery is considered accurate to the studies included in this systematic review. However, the low quality of the studies makes that the development of randomized clinical trials are needed to assess whether it really brings major benefits to the patient and to the surgical procedure compared to conventional planning / Os objetivo do presente estudo s?o realizar uma revis?o sistem?tica para avaliar a acur?cia do planejamento assistido por computador em cirurgia ortogn?tica, averiguar a qualidade da literatura atual e a necessidade de novas metodologias sobre o assunto. A busca sistem?tica na literatura foi efetuada nas bases de dados PubMed, EMBASE, Biblioteca Cochrane, LILACS e SciELO. A literatura cinza foi investigada no Google Acad?mico e nos anais dos congressos mais importantes de Cirurgia e Traumatologia Buco-Maxilo-Facial. Os artigos encontrados passaram por um crit?rio de sele??o e elegibilidade por dois autores de maneira cega e independente. Ap?s a sele??o dos estudos eleg?veis, realizou-se uma busca manual nas refer?ncias desses, fez-se extra??o dos dados e a an?lise de qualidade dos mesmos. Atrav?s da busca nas bases de dados foram encontrados 350 artigos. Desses 33 foram selecionados para leitura na ?ntegra e seis foram inclu?dos no estudo. Atrav?s da busca na literatura cinza, quatro artigos foram selecionados para leitura na ?ntegra e apenas um foi inclu?do no estudo e a partir da busca manual um artigo foi inclu?do. Dessa maneira, oito estudos foram inclu?dos nesta revis?o sistem?tica. O n?vel de concord?ncia entre os autores para sele??o dos estudos foi considerado substancial (kappa= 0,767) e para elegibilidade dos estudos foi considerado excelente (kappa= 0,863). A acur?cia no planejamento assistido por computador em cirurgia ortogn?tica nos sentidos de transla??o foi menor do que 1,2 mil?metros na maxila (vertical) e menor do que 1,1 mil?metros na mand?bula (sagital), e nos sentidos de rota??o foi menor do que 1,5? na maxila (pitch) e menor do que 1,8? na mand?bula (pitch). Dois estudos apresentaram potencial m?dio para risco de vi?s e seis estudos apresentaram potencial alto para risco de vi?s. O planejamento assistido por computador em cirurgia ortogn?tica ? considerado acurado pelos estudos inclu?dos nesta revis?o sistem?tica. A baixa qualidade dos artigos, entretanto, faz com que seja necess?ria a elabora??o de ensaios cl?nicos randomizados para avaliar se ele realmente traz maiores benef?cios ao paciente e ? pr?tica cir?rgica quando comparado ao planejamento convencional
