Patient-Fitted Total Temporomandibular Joint Prosthesis: A Case Series

Abstract

The treatment protocol of patients having end-stage temporomandibular joint (TMJ) disorder using patient-fitted TMJ prosthesis is presented in this case series. The prosthetic fossa and ramus components and the surgical guides were designed on the basis of the final position of the maxilla-mandibular skeleton using Geomagic software (Morrisville, North Carolina, USA). The prosthetic ramus component and the supporting frame of the fossa were produced using a titanium alloy. The fossa component was constructed solely from ultra-high molecular weight polyethylene. Patient-fitted TMJ prosthesis was placed through high submandibular and pre-auricular approach in 3 patients. No complication related to the operations was seen. Temporomandibular joint reconstruction using patient-fitted TMJ prosthesis resulted in satisfying jaw function and skeletal relationships in patients having end-stage TMJ disorder.
