Prediction Accuracy of Dolphin 3D in Bimax Surgery for Class III

Patients with class III dentofacial deformity who are in need of surgical correction are now able to see the potential changes to their faces before the actual operation. Dolphin 3d is one of the few software packages that is used for orthognathic planning and prediction of soft tissue changes. The direct effect of the prediction procedure over patient's and surgeon decisions makes it important to guarantee a high level of accuracy of operational results prediction. This study is designed to investigate the accuracy of Dolphin 3d software for the prediction of postoperative soft tissue changes following specific surgical procedure which is the combined maxillary advancement and mandibular setback, commonly used for correction of class III facial deformity cases. The study data will be collecting retrospectively. The difference between the pre-operative soft tissue prediction and the 6-month postoperative results will be analysed. The results of this study will help to determine whether this software package is accurate enough to be considered as a surgical assistance tool helping both surgeons and patients in treatment planning and decision-making procedure respectively.
