RESUMO
Este estudo analisou traçados digitais obtidos por dois programas de computador (Dolphin Imaging® e Nemotec®) em comparação aos obtidos pelo método manual nas análises cefalométricas SNA, SNB, Co-A, Co-Gn, altura facial anterior, A-Nperp, Pg-Nperp e plano mandibular. 30 pacientes leucodermas, portadores de retrognatismo mandibular, foram avaliados e submetidos à cirurgia ortognática para correção da deformidade por meio da osteotomia sagital do ramo mandibular. Os traçados cefalométricos foram realizados em telerradiografias laterais obtidas uma semana antes da cirurgia. O método Manual e o Nemotec® apresentaram excelente confiabilidade em todas as medidas. Por outro lado, o método Dolphin Imaging® apontou baixa confiabilidade nas medidas altura facial anterior, Co-A e Co-Gn. Nas medidas A-Nperp, Pg-Nperp, Plano md, SNA e SNB, não houve diferença entre três métodos estudados. Na medida altura facial anterior, houve diferença entre os métodos Dolphin Imaging® e Nemotec®, mas não foram observadas diferenças em relação ao método manual. Nas medidas Co-A e Co-Gn, foi observado que o método Dolphin Imaging® apresentou média significativamente inferior aos demais métodos estudados. No método manual, somente as medidas Co-Gn, Pg-Nperp e SNB confirmaram o diagnóstico de retrognatismo mandibular, tendo o programa Nemotec® apresentado resultados melhores que o programa Dolphin Imaging®...

ABSTRACT
This study analyzed digital tracings obtained by two different computer software programs (Dolphin Imaging® and Nemotec®) and compare them to the manual method using cephalometric measurements SNA, SNB, Co-A, Co-Gn, anterior facial height, A-Nperp, Pg-Nperp and mandibular plane. Thirty Caucasian patients exhibiting mandibular retrognathia were analyzed and were submitted to orthognathic surgery to correct the deformity by bilateral sagittal split osteotomy. The cephalometric tracings were performed with lateral radiographs that were obtained a week prior to the surgery. The manual method and the Nemotec® software exhibited an excellent reliability in all measurements. However, the Dolphin Imaging® method exhibited low reliability in the anterior facial height, Co-A and Co-Gn measurements. For the measurements of A-Nperp, Pg-Nperp, Mandibular plan, SNA and SNB, there were no significant differences between the three methods studied. For the anterior facial height measurement, a statistically significant difference was found between the Dolphin Imaging® and Nemotec® methods, although not in relation to the manual method. For the Co-A and Co-Gn measurements, the Dolphin Imaging® method exhibited a significantly lower mean than the other methods studied. In manual method, only the Co-Gn, Pg-Nperp and SNB measurements confirmed the diagnosis of mandibular retrognathia and Nemotec® software provided better results than Dolphin Imaging®... (AU)
