Finite element stress analysis in dentistry reveals stress concentrations in all-ceramic crowns, post crowns, and implant abutments. Understanding these stress distributions aids in designing dental restorations to prevent abutment tooth fracture.
Area of Science:
- Biomaterials Science
- Mechanical Engineering
- Dental Science
Context:
- Finite element stress analysis is a valuable tool in modern stomatology.
- Previous studies have explored stress distribution in various dental restorations.
Purpose:
- To summarize stress distributions in all-ceramic crowns, post crowns, fixed partial dentures, and implant-supported fixed dentures.
- To investigate stress levels in the periodontal ligament of abutment teeth using the finite element method.
Summary:
- Tensile and compressive stresses concentrate at the cervical margins of all-ceramic and post crowns.
- The highest stress is observed on the surface of the crown.
- Stress concentrates at the connector of fixed partial dentures, with molars being ideal abutments.
- Maximum stress occurs around the neck of implant abutments.
Impact:
- Provides a theoretical foundation for clinical dentistry in restoration design and manufacturing.
- Highlights the importance of avoiding horizontal loading on prostheses to enhance abutment tooth fracture resistance.

The shearing force, possessing potential directionality within the plane of the section, is simplified into two component forces running parallel to the x and y axes.
General State of Stress
Specifically, consider a tetrahedral element where one face, labeled XYZ, is perpendicular to the line OA, and the remaining faces align with the coordinate axes with point O as the origin. At any point, such as point O, the stress tensor can be used to determine the stress...
