Summary
Polyetheretherketone (PEEK) can be enhanced for dental implants by modifying its surface at the nanoscale. These surface treatments improve PEEK
Area of Science:
- Biomaterials Science
- Dental Implantology
- Nanotechnology
Background:
- Polyetheretherketone (PEEK) is a promising material for dental implants due to its mechanical properties.
- However, PEEK exhibits limited bioactivity, hindering optimal osseointegration.
- Enhancing PEEK's bioactivity is crucial for its successful clinical application as a dental implant material.
Purpose of the Study:
- To review and assess literature on modifying polyetheretherketone (PEEK) to improve its bioactivity.
- To evaluate methods for making PEEK more suitable for dental implant applications.
- To identify effective surface modification strategies for PEEK.
Main Methods:
- Conducted an electronic literature search using PubMed and Google Scholar.
- Keywords included: "PEEK dental implants," "nano," "osseointegration," "surface treatment," and "modification."
- Included 16 in vivo and in vitro studies in the review.
Main Results:
- Multiple viable methods exist to enhance PEEK's bioactivity.
- Key strategies involve increasing surface roughness and hydrophilicity.
- Coating PEEK with osseoconductive materials shows significant potential.
Conclusions:
- Nanoscale modifications can overcome PEEK's inherent bioactivity limitations.
- Melt-blending with nanoparticles creates bioactive nanocomposites.
- Surface modifications like spin-coating and plasma treatments enhance bioactivity.
- Further animal studies are required to validate these modified PEEK implants for dental use.
