Are zirconia dental implants the answer? The vast majority of dental implants are titanium alloys that have been in use since the mid 1960s.
The focus is whether the actual implant screw is made of zirconia or titanium. Zirconia dental implants are attractive for those that may be concerned about a metal allergy. In this blog post I describe the pros and cons of zirconia dental implants. As of the year 2015, I would not recommend them… The scientific evidence and clinical practice does not support their claims.
The one piece design in itself is a very limiting factor. The implant cannot be redirected by an abutment…. Right or wrong, position cannot be changed.
In my dental office in Burbank, California, I commonly use zirconia as the crown or bridge portion. It is also very useful as an abutment which is the intermediary piece on a two-piece dental implant. Both the crown/bridge and abutment portion are not embedded into the bone. Zirconia bridges such as the Prettau dental implant bridge is extremely strong as long as it is made very thick.
In this post I also discussed what happens when orthopedic surgeons use zirconia as a hip replacement material.... You will be shocked to hear the results!!
