The evaluation of this algorithm is presented on analytical surface triangulations by comparing it with other recognized fitting methods according to three criteria: convergence, precision and robustness. By experimenting on various data, we show that the Sinefitting algorithm is less affected by errors in vertex normal estimation.} }

A recurrent problem is to maintain the position of the mandibular condyle as SSRO separates the anterior mandible and the condylar process. Alteration of condylar position can lead to malocclusion with a risk of relapse and temporo-mandibular disorders. The quality of the procedure depends on the operators experience. The purpose of this cadaveric and clinical study is to present splint and Condylar Positioning Devices (CPDs) produced using 3D Computed Aided Design/Computed Aided Manufacturing (CAD/CAM) technology. The aim is to keep condyles the closest to their preoperative position with postoperative planned occlusal position using 3D printed splint and CPDs during SSRO. Materials and methods: External surface of 3D CT scan of cranio- facial skeleton was extracted as a 3D mesh. SSRO was planned virtually. On one cadaver, occlusal splint and right and left anatomic maxillo- mandibular plates for condylar positioning were designed and manufactured. For one patient, latero-mandibular plates were fixed on the occlusal splint. A postoperative CT scan was performed after bilateral SSRO. We compared the virtual final position and the real postoperative position of occlusion and condyles. Results: In cadaver and patient, the final occlusion was good and condylar movement was minimal. In anteroposterior plane comparison between planed condyle position and post-operative position show an infra- millimeter precision. Conclusion: This new splint allows to obtain a good precision of the occlusal and condylar movements during SSRO. It is also simple and easy for surgeons who use CPDs. Here are presented first surgical results using the complete processing chain. Future works will focus on the automation of each process.} }
