Use of Patient-Specific Finite Element Models in Dental Rehabilitation to Investigate Stresses of a Fibula Free Flap for Mandibular Reconstruction.

Purpose: This study investigated the effect of implant length, diameter, and surface contact on the stresses developed in a fibular free flap.

Materials And Methods: Finite element (FE) models for dental implants placed in a patient-specific fibula were created using a patient-specific fibula CT scan and geometry files of commercially available dental implants. The FE models involved nine dental implants of different lengths and diameters: 3.
