It is one of the most scrutinized dental implant surface on the market, and long-term success with TiUnite surface implants is made evident yet again. In a newly published study comparing five implant surfaces, TiUnite has come out on top1.

For improved osseointegration, implant design and implant surfaces have been continuously changing for many years: From turned and titanium plasma-sprayed surfaces in the 1980s, to blasted, etched and anodized (namely, TiUnite), and more, in the 1990s and 2000s.

Dr. WennebergA world-leading authority in dental implant surfaces, Professor Ann Wennerberg has led a systematic review of 62 clinical studies, analyzing a total of over 17,000 implants* with at least 10 years’ follow-up. The study compares the long-term clinical outcome of treatment with different surfaces.

TiUnite showed a significantly higher survival rate than surfaces used by other brands, at 98.5% (p<0.05).

Comparing sandblasted and acid-etched implants versus turned implants, there was no significant difference in survival; 96.7% and 96.4% respectively.

These results from long-term studies are consistent with previous findings showing anodized surfaces are associated with a high probability of implant survival and predictable long-term outcomes.2
