RESUMO ABSTRACTProcedimentos cirúrgicos ortognáti cos; Validação de programas de computador; Má oclusão de Angle classe III.Orthognathic surgical procedures; Soft ware validati on; Malocclusion, Angle class III. Finally, measured the rate of skeletal movements at in three dimensional of spaces. Fift een angular and linear variables were measured, and the results, analyzed using the stati sti cal soft ware stati sti cs. For each pati ent, the manual and computer soft ware predicti on before and aft er surgery were compared with each other. The paired t-test was used to evaluate possible diff erences between manual and computer soft ware predicti on (p<0.05). DESCRITORES KEYWORDS Results:The diff erence of the variables of the soft ware predicti on in the pre and postsurgical stages in comparison with standard manual predicti on method was insignifi cant. Conclusion: Dolphin Imaging soft ware (version 10.0) has a good accuracy for predicti on of pre and postsurgical outcome of orthognathic samples.

“…The majority of these ratios are derived from Wolford et al [33,38]. Recently, the release of the latest version (Quick Ceph2000) incorporated many advantages, including capture and storage of high resolution images, treatment simulations, growth forecasts, compatibility with any operating system and digital image enhancement of tracing accuracy [44].…”

“…Despite advances in surgical techniques concerning function, stability and aesthetics, and the promising capabilities of 3D technology, oral maxillofacial surgeons and orthodontists have not been able to yet develop an objective method to predict the soft tissue outcome after orthognathic surgery [44,57,93].…”

“…Systematic reviews investigating the accuracy of computer programs in predicting skeletal and soft tissue changes after orthognathic surgery showed that computer programs cannot consistently predict the skeletal changes occurring after orthognathic surgery but their results may be considered inside a clinically acceptable range [44] and that the most significant area of error in prediction of soft tissue profile is the lower lip area, error that could have clinical implications. No software program was shown to be superior in prediction accuracy compared with its competitor [70].…”

Over the past decade the growing number of adult patients seeking for orthodontic treatment made orthognathic surgery popular. Surgical and orthodontic techniques have developed to the point where combined orthodontic and surgical treatment is now feasible to manage dentofacial deformity problems very satisfactorily. The prediction of orthognathic treatment outcome is an important part of orthognathic planning and the process of patient' inform consent. The predicted results must be presented to the patients prior to treatment in order to assess the treatment's feasibility, optimize case management and increase patient understanding and acceptance of the recommended treatment. Cephalometrics is a routine part of the diagnosis and treatment planning process and also allows the clinician to evaluate changes following orthognathic surgery. Traditionally cephalometry has been employed manually; nowadays computerized cephalometric systems are very popular. Cephalometric prediction in orthognathic surgery can be done manually or by computers, using several currently available software programs, alone or in combination with video images. Both manual and computerized cephalometric prediction methods are two-dimensional and cannot fully describe three-dimensional phenomena. Today, three-dimensional prediction methods are available, such as three-dimensional computerized tomography (3DCT), 3D magnetic resonance imaging (3DMRI) and surface scan/cone-beam CT. The aim of this article is to present and discuss the different methods of cephalometric prediction of the orthognathic surgery outcome.

Aos meus familiares pela ajuda, paciência e compreensão, em especial aos meus pais, Clóvis e Rosa, e a minha avó Guilhermina. A família é e sempre será o alicerce principal da vida. Obrigado pelos ensinamentos e pelo amor incondicional; sou o que sou graças a vocês.Ao meu querido e amado irmão, Diego, um exemplo, verdadeira inspiração pessoal e profissional.A minha amada esposa, Tatiana, sinônimo de amor, alegria, companheirismo.Obrigado por me apoiar sempre e me amar desta forma única. Encontrar o amor verdadeiro é para poucos e certamente faz a vida muito melhor, diminuindo as dificuldades e engrandecendo as conquistas. O sucesso da cirurgia ortognática está relacionado com diversos fatores como análise facial precisa e acurada, e exames de imagem com alta qualidade.Atualmente, diversos programas de imagens tridimensionais, comerciais e abertos, estão disponíveis no auxílio diagnóstico, elaboração do plano de tratamento e simulação do procedimento cirúrgico para correção das deformidades dentofaciais.Entretanto, estudos avaliando os diferentes métodos de mensuração linear empregados pelos programas de imagem por meio da reconstrução 3D no planejamento da osteotomia tipo Le Fort I são escassos e, maiores esclarecimentos sobre sua precisão e a acurácia são necessários. O objetivo deste estudo foi estabelecer: a) precisão e acurácia de medidas lineares tridimensionais para osteotomia tipo Le Fort I obtidas por meio da tomografia computadorizada multislice and 0.88 0.98 for observers 1 and 2 respectively using the Vitrea; 0.58 to 0.90 and 0.48 to 0.85 for OsiriX, and 0.80 to 0.96 and 0.57 to 0.92 using Dolphin. Vítrea software showed no statistically significant differences for intra-and inter-observer analysis and physical measurements using MSCT and CBCT. Regarding the analysis of software's, statistical differences were found with the program OsiriX and Dolphin in comparison to gold standard.
