Accuracy of custom-fitted temporomandibular joint alloplastic reconstruction and virtual surgical planning

The purpose of this study was to evaluate the accuracy of temporomandibular joint (TMJ) custom-made replacements by means of virtual surgical planning.The authors review 11 TMJ custom-made prostheses made of both mandibular and fossa components. Surgeries were virtually planned and patient-specific devices were designed together with surgical cutting and positional guides. Three-dimensional models for both preoperative planning and postoperative computed tomography scans were generated and overlapped in order to evaluate differences in measurements.
