Purpose:
The purpose of this study was to study the treatment outcomes and accuracy of the digital prediction using Dolphin Imaging Software and the actual postoperative outcome in subjects presenting Class III malocclusions.
Materials And Methods:
Maxillary advancement surgery was performed in group 1, and maxillary advancement was combined with mandibular setback surgery in group 2. Predictive cephalometric tracings were made using Dolphin Imaging Software.
Results:
Before surgery, the maxillary deficiency was significantly greater in group 1 than in group 2, and the mandibular length was significantly greater in group 2. Surgical reductions in mandibular length and angle were significantly greater 12 months after surgery than indicated by the predictive cephalometric tracings.
Conclusion:
In groups 1 and 2, maxillary advancement surgery was performed in accordance with the Dolphin Imaging Software. The mandibular setback surgery performed was beyond the established plan, but without clinical implications. Mandibular dentoskeletal measurements showed a greater correlation with the profile than the maxillary measurements.
