Predicted vs. Attained Surgical Correction in an Orthognathic Surgery Patient Population Using CBCT

Abstract

Purpose: To validate the effectiveness of Mimics software, using Cone Beam Computed Tomography (CBCT), in predicting the soft tissue changes from orthognathic surgery. Methods: CBCTs for 10 patients were superimposed, pre- and post- Bilateral Sagittal Split Osteotomy (BSSO) advancement, to measure the exact surgical skeletal moves, which were modified within Mimics to create 3-D pre-surgical soft tissue predictions. Corresponding soft tissue landmarks were identified on the pre-surgical and the final soft tissue matrices, and discrepancies between corresponding points were measured using Geomagic.
