Abstract

Posterior tooth loss disrupts occlusal support, mandibular kinematics and elevates TMJ loading and TMD risk. Therefore, it is of interest to used 3D FEA and dynamic condylar analysis in 42 unilateral posterior edentulous patients across implant (n=15), RPD (n=14) and untreated (n=13) groups. Implant restoration reduced peak condylar cartilage stress 41.2% (18.7±4.1 to 11.0±2.6 MPa, p<0.001) and disc stress 38.7% (p<0.001), unlike RPD/untreated controls. Clinical TMD prevalence dropped from 66.7% to 13.3% in the implant group versus minimal change elsewhere. Implants uniquely normalize TMJ biomechanics and halt TMD progression, advancing evidence-based posterior restoration protocols
