Finite Element Analysis of Low-Profile Reconstruction Plates for Atrophic Mandibles—Part II: A Comparison of Customized Plates with 3D Grid-Type and Conventional Designs

Key Points

The customized plate demonstrated the best biomechanical performance with the lowest peak plate stress, indicating its effectiveness for atrophic mandibles.
In the comparison, the 3D grid-type plate notably reduced peak plate stress while producing the highest peak screw stress among the designs assessed.
Using finite element analysis, the study evaluated stiffness and stress distribution rather than focusing on failure load or fatigue resistance.
Practical aspects like manufacturing time and resource needs may prioritize off-the-shelf plates, though a formal cost analysis was not conducted.

Abstract

Within the limitations of a linear static FEA (stiffness/stress distribution rather than failure load or fatigue resistance), the customized plate (G3) demonstrated the most favorable biomechanical performance (lowest peak plate stress). The 3D grid-type plate (G2) reduced peak plate stress compared with the conventional design (G1) but produced the highest peak screw stress. Practical considerations such as manufacturing lead time and resource requirements may favor off-the-shelf plates; however, a formal cost or operative-time analysis was not performed.
