Abstract

Zirconia has emerged as a promising alternative to titanium in dental implantology due to its exceptional mechanical, mechanical and biological properties. This review discusses zirconia dental implants, focusing on their influence on osseointegration, one-piece designs, immediate placement after tooth extraction, and root-analogue implant designs. Studies proved that zirconia implants achieves osseointegration that is comparable to titanium implants however, they have the advantage of reduced biofilm formation and favorable early healing. One-piece zirconia implants eliminate the fixture-abutment interface, reducing peri-implant complications. Immediate placement of zirconia implants has shown success rates similar to delayed protocols. Root-analogue zirconia implants enhance stress distribution and esthetics but require further investigations. Although zirconia implants show acceptable outcomes, concerns regarding long-term predictability, crestal bone loss, and the need for additional clinical trials remain. This review underscores the advancements and limitations of zirconia implants, highlighting the necessity for continued research to optimize their clinical performance and long-term success.
