Abstract: Introduction: The purpose of this study was to study the treatment outcomes and the accuracy of digital prediction and the actual postoperative outcome with Dolphin program on subjects presenting Class II malocclusions. Methods Forty patients underwent surgical mandibular advancement (Group 1) and 40 underwent combined surgery of mandibular advancement and maxillary impaction (Group 2). The available pre surgical (t1) and a minimum of 12 months post surgical (t2) cephalometric radiographs were digitized. Predictive cephalograms (t3) for both groups were traced. Results At all times evaluated, Group 1 displayed a shorter mandibular length and Group 2 had a longer lower face. In both groups the surgical interventions (t2) were greater than initially predicted. There was no significant difference between groups with regards to overjet, overbite and soft tissue measurements. Conclusions In both groups surgeries were more extensive than planned. Facial convexity and the distance of the lips to cranial base presented similar values between t2 (post surgical) and t3 (predicted).
