The good chemical stability, biological properties and mechanical properties of polyether ether ketone (PEEK) composites close to those of natural teeth and dense bone have made them widely used in clinical areas such as dental prosthetics, implants, orthodontics and maxillofacial surgery. In this paper HONCHON SMILE provides a review of the application of PEEK materials in the dental field.

Basic properties of PEEK

PEEK has high mechanical strength, can withstand high temperatures and corrosion, has a low wear rate, and also has good processing properties, and can be well compounded with inorganic fillers such as glass fiber and carbon fiber to meet different clinical needs. With the development of digital technology, 3D printing to make PEEK personalized restorations has a broad application prospect in the clinical field.

Fixed Denture Restorations

Although PEEK has a lower modulus of elasticity and hardness than traditional metal alloys, it has similar wear resistance to metal alloys and similar mechanical properties to natural dental tissues. PEKK has sufficient mechanical and physical properties to be used as a permanent full-crown restoration compared with other materials of the same parameters.

Removable denture restorations

Conventional removable partial denture brackets are usually made of cobalt-chromium alloy (Co-Cr), which has many disadvantages, such as allergic reactions and aesthetic problems with metal exposure. For patients who are metal sensitive and cannot accept the presence of metal in the mouth, PEEK can be used as an alternative material to metal brackets in clinical applications.

Periodontal field

PEKK materials are lighter in mass compared to traditional metal restorations due to their lower density values, which can improve patient comfort and better retention and stability of the restoration. In addition, PEKK materials have lower surface energy, which is not conducive to plaque adhesion and aggregation, and is conducive to the maintenance of oral hygiene after wear by patients.

Implants

PEEK is widely used in the field of implantology. As the elastic modulus of PEEK is low compared to cortical bone, titanium and ceramic materials, a variety of clinically enhanced PEEK composites have been developed, such as carbon fiber reinforced polyether ether ketone (CFR-PEEK) and glass fiber reinforced polyether ether ketone (GFR-PEEK), both of which are relatively close to the elastic modulus of normal human bone cortex.

Oral and maxillofacial surgery

PEEK does not cause any toxicity, mutagenic effects, or significant inflammatory reactions. In addition, due to the material's better aesthetic properties and excellent biomechanical properties, PEEK materials have attracted widespread attention from clinicians in recent years. Studies have demonstrated the feasibility of 3D printed PEEK for skull repair, the safety and reliability of the material, and its efficacy.
