Radiographic Assessment of Three Dimensional Mandibular Position Using Splint-less Patient Specific Implant Following Bilateral Sagittal Split Osteotomy
The purpose of this study was to assess the accuracy of a splint-less approach for mandibular jaw orthognathic surgery. This approach utilized a personalized orthognathic surgical guide (POSG) system, which comprised a set of cutting guides and 3D printed custom titanium fixation plates for bilateral sagittal split osteotomies (BSSOs). The cutting guides were first used to predrill screw holes and guide osteotomies. The custom plates were then used to reposition and stabilize the bony segments as planned, without the use of surgical splints or any additional tool such as surgical navigation
• Patients suffering from skeletal deformity requiring mandibular orthognathic surgery (Bilateral sagittal splitting osteotomy).
• Patients should be free from any systemic disease that may affect normal bone healing and predictable outcome.
