In Silico Modeling of Safe Force Limits for Trismus Therapy Following Jaw Reconstruction.

ABSTRACT:

Background and objective

Restricted mouth opening (trismus) is a common complication following segmental mandibulectomy and autologous bone reconstruction. However, the biomechanical limits of reconstructed mandibles, particularly in cases without bone union, remain poorly understood. Restorabite is a novel jaw-stretching device designed to increase the safety of trismus therapy by controlling the applied force. This study estimates the patient-specific loading limits in compromised mandibular reconstruction using finite element analysis to guide safe trismus therapy.

Methods

Based on patient imaging, the finite element method was used to model stress distributions in the bone, titanium plate, and screws of a reconstructed mandible lacking bone union. Various scenarios were
