Three-Dimensional Finite Element Analysis of Occlusal Load Distribution in Endodontically Treated Premolars Restored with Fiber-Reinforced and Metal Post Systems
Abstract
This study investigates occlusal load distribution in endodontically treated maxillary premolars restored using fiber-reinforced composite (FRC) and metal post systems through three-dimensional finite element analysis (3D FEA). The analysis simulates functional occlusal loading and examines stress concentration patterns in different restorative setups. The findings highlight the biomechanical advantages of fiber posts in reducing stress at the root dentin-post interface and preserving tooth structure integrity.
