Area of Science:

• Biomaterials Science
• Dental Materials
• Polymer Science

Background:

• Polyetheretherketone (PEEK) is a high-performance semicrystalline biomaterial.
• PEEK possesses superior physical properties including high resilience, strength, and aesthetic tooth color.
• Its biocompatibility and mechanical advantages drive increasing use in dental applications.

Purpose of the Study:

• To review the qualities and properties of PEEK as a biomaterial for dental implant prostheses.
• To focus on the application of PEEK in dentistry, particularly for dental implants.
• To discuss the challenges, benefits, and advantages of using PEEK in dental applications.

Main Methods:

• Review of existing literature on Polyetheretherketone (PEEK) in dentistry.
• Analysis of PEEK's physical and mechanical properties relevant to dental applications.
• Examination of PEEK's use in various dental prostheses, including implants, frameworks, and restorations.

Main Results:

• PEEK exhibits high strength, resilience, fracture resistance, and stress distribution capabilities.
• Its tooth-colored appearance enhances aesthetic outcomes in dental restorations.
• PEEK demonstrates excellent compatibility with bioactive materials and osseointegration potential.
• Traditional manufacturing methods like injection molding are suitable for PEEK.

Conclusions:

• PEEK is a highly capable biomaterial offering an 'all-in-one' solution for various dental applications.
• Its unique properties provide significant advantages over traditional materials in implantology and prosthodontics.
• Despite its cost, PEEK's durability, strength, and biocompatibility justify its use in demanding dental procedures.
