Background:

Titanium implants can elicit unfavorable host responses, leading to fibrous encapsulation and aseptic loosening at the bone-implant interface.
Improving osseointegration is critical for enhancing the clinical longevity and success of orthopedic implants.
Current research explores novel coating strategies to overcome the limitations of traditional titanium implants.

Purpose of the Study:

To review and discuss various coating materials and techniques for orthopedic implants.
To evaluate the advantages and disadvantages of different coating materials.
To assess the biological performance and osseointegration potential of coated implants.

Main Methods:

Literature review of recent studies on implant coatings.
