|June 26, 2023
Summary
Polyetheretherketone (PEEK) shows adequate mechanical properties for dental prostheses, but cobalt-chromium (Co-Cr) alloys offer superior performance for removable partial denture frameworks and clasps.
Area of Science:
- Biomaterials Science
- Dental Materials Science
- Polymer Engineering
Background:
- High-performance thermoplastic polymers like Polyetheretherketone (PEEK) are explored as alternatives to traditional metallic components in dental prostheses.
- Removable partial dentures (RPDs) often utilize cobalt-chromium (Co-Cr) alloys for frameworks and clasps due to their mechanical strength.
Conclusions:
- While PEEK is a viable material for certain dental applications, Co-Cr alloys remain the preferred choice for RPD frameworks and clasps due to enhanced mechanical performance.
- Further research may explore modifications to PEEK or specific clinical scenarios where its properties are advantageous.
- The review highlights the importance of material selection based on mechanical properties for long-term success of dental prostheses.
