Evaluation of Stress and Fatigue on Different Implant Lengths in the Rehabilitation of Atrophic Mandibles with Full-Arch Fixed Prosthesis Using Finite Element Method.

Purpose: This research aimed to evaluate the stress and fatigue generated in short implants compared to regular implants in rehabilitation with fixed full-arch implant-supported prostheses in atrophic mandibles using the finite element method (FEM).

Materials And Methods: Four models were constructed with different implants lengths: 4, 6, 8, and 10 mm. A 100-N oblique load was applied to evaluate the stress on the bone, implant, and prosthetic components.

Comparative finite element analysis of the biomechanical stability of 2.0 fixation plates in atrophic mandibular fractures.

Purpose: The objective of the present study was to conduct a computational, laboratory-based comparison of the biomechanical stability of 2.0 fixation locking plates with different profiles in Class III atrophic mandibular fractures using 3-dimensional finite element analysis.

Materials And Methods: Three-dimensional finite element models simulating Class III atrophic mandibular fractures were constructed.
