Surface morphology is more important for osseointegration than surface composition. In terms of inhibiting bacterial adhesion, zirconia is superior to titanium and, therefore, more suitable for abutments. Both materials show a similar ability to adhere to soft tissues.
Titaniumis stronger and more durable than zirconium, but zirconium implants are more biocompatible with the human body.
When it comes to success rate, titanium implants have a rate of up to 95%, while zirconia is lower. Zirconia has no metal in its composition, making it an excellent choice for patients who are allergic to metals. When choosing between titanium and zirconia implants, it all comes down to personal preference. Titanium implants are cheaper and more durable, and may be sufficient to replace the back teeth.
On the other hand, zirconium oxide, also known as zirconia, is comparable to titanium in terms of strength, however, it contains little or no metal. Zirconia is also durable, corrosion-resistant and capable of fusing with surrounding bone just like titanium. However, unlike titanium, zirconia is lighter in terms of weight and color. It was these characteristics that ultimately led to the development of a metal-free zirconium implant.
Two-piece zirconium dental implants are now available, making it easier for these dental implants to remain intact while osseointegration is complete. Today, a much larger number of doctors are opting for titanium instead of zirconium dental implants because they know that these implant systems have been studied exhaustively for decades, providing greater peace of mind. Ultimately, when it comes to choosing between titanium and zirconia implants, it all comes down to personal preference.
