I recently went to a course on Zirconia dental implants. Apparently they are more popular in Europe. A number of distinctions between titanium and zirconia implants were made.
Once zirconia is milled it becomes an oxide changing it from a metal to ceramic
•
The titanium implant surface is an oxide which creates a foreign body reaction
•
Since zirconia is white and less porous than the modified titanium implant surfaces, exposure of the implant at the tissue level is less problematic
•
With intentionally exposed zirconium implants, the soft tissue creeps crownally over time
•
The soft tissue responds much more favorably to zirconia than titanium
•
Researchers are now studying the metal dissolution that the titanium alloys have, which creates a more acidic environment and may play a significant role in peri-implantitis
•
Zirconia implants take longer to integrate as the implant surface doesn’t have as much topographic variation
•
Blood flow around a zirconia implant is 13% better than titanium and there is less inflammation around zirconia implants
•
Success rates of 96 (over 10 years) to 98.4% are being achieved with current zirconia implant designs
•
2 piece zirconia implants have stock abutments, which can be modified by cementing a screw retained implant crown on them.
•
Xeramax, the zirconia implant I use has a one use carbon fiber screw that fills the screw chamber and nearly eliminates the odor between the implant and abutment
•
A temporary screw comes with each implant for laboratory use
•
Xeramax also has double the strength of the Bruxer crown by Glidwell
•
Zirconia implants are projected to grow 50% a year in the dental implant market
