In vitro study reveals new PEEK materials enhance stiffness and polishability for prosthetic frameworks, suggesting viable alternatives.
The investigated PEEK materials demonstrated superior stiffness without compromising flexural strength, outperforming unfilled PEEK and conventional fiber-reinforced PEEK in terms of polishability and esthetics with comparable biocompatibility to unfilled PEEK. The findings suggest that the compounds could represent viable alternative prosthetic framework materials for fixed implant-supported restorations.
