Development of Pre-operative Planning Assistance Framework for Oral and Maxillofacial Surgery

—Development of Integrated Pre-Processing Module for 3D Contact Analysis of Temporomandibular Joint and Retrospective Evaluation—

Abstract

Sagittal split ramus osteotomy (SSRO) is the most common surgical treatment for jaw deformity patients. In the pre-operative planning of SSRO, it is desirable to perform 3D contact analysis of the temporomandibular joint. The purpose of this study is to develop the pre-operative planning assistance framework in order to perform the 3D contact analysis more easily. This framework includes an automated segmentation sub-module, a 2D-3D conversion sub-module for occlusal power zone, and the 3D contact analysis sub-module. In the experiments, we performed a retrospective evaluation with 8 patients and confirmed the usefulness of the proposed framework.
