Abstract

BACKGROUND: Accurate placement of TMJ implant components may be facilitated by virtual surgical planning (VSP) technologies. The aim of this study was to assess the accuracy of a typical VSP protocol and describe the pattern of surgical error associated with total alloplastic TMJ replacement. METHODS: A retrospective analysis was undertaken on 40 adult patients who were implanted with a fully customised, 3D printed TMJ prosthesis due to end-stage TMJ disease. Planned TMJ implant position based on preoperative CBCT images was compared with final position on postoperative OPGs using a previously validated linear rescaling method. Translational discrepancy was described in the anterior-posterio..
