Titanium vs zirconia dental implants

Bosshardt, Chappuis and Buser reviewed how bone heals onto titanium, titanium-zirconium and zirconia dental implants; micro-rough surfaces speed bone bonding (osseointegration) on titanium, and surface changes also affect how fast zirconia implants integrate.

As reported in: Bosshardt, Chappuis, Buser (2016). Osseointegration of titanium, titanium alloy and zirconia dental implants: current knowledge and open questions. Periodontology 2000. doi:10.1111/prd.12179
