Comparação Entre os Prognósticos do Planejamento Cirúrgico Manual ou por Software em Cirurgia Ortognática

Abstract

Objective: To evaluate the proximity of computer imaging software surgical planning prediction methods, with standard manual methods. Method: Lateral cephalometry radiographs and study cast records of pre and post surgery of twenty longface Cl III patients (12 Females and 8 Males, mean age: 22.5 ± 2.3), that had been undergone surgery in Department of Orthodontics. For manual prediction, with combination of pre and post surgical occlusograms with lateral cephalometric radiograph tracings of each samples, three dimensional analysis was done. Predictions of skeletal movement with tacing overlay method, has prepared. Finally, measured the rate of skeletal movements at in three dimensional of spaces. Fifteen angular and linear variables were measured, and the results, analyzed using the statistical software statistics. For each patient, the manual and computer software prediction before and after surgery were compared with each other. The paired t-test was used to evaluate possible differences between manual and computer software prediction (p<0.05). Results: The difference of the variables of the software prediction in the pre and postsurgical stages in comparison with standard manual prediction method was insignificant. Conclusion: Dolphin Imaging software (version 10.0) has a good accuracy for prediction of pre and postsurgical outcome of orthognathic samples.
