Result

The findings in this study are extremely relevant for dentists and patients who base their choice of implant on independent clinical evidence. These results add weight to previous reported findings showing high success rates with Straumann implants.5

The probability of being diagnosed with peri-implantitis4 9 years after implant therapy was lowest with the Straumann TL SLA implants.

If implant loss had occurred prior to connection of the supraconstruction, it was scored as an early implant loss. If the loss had occurred afterward, it was considered a late implant loss.

ConclusionThese findings are extremely relevant for dentists and patients who want to choose an implant system on the basis of independent published clinical evidence. They add to the unparalleled body of long-term clinical data supporting Straumann’s dental implant system. Impressive long-term outcomes have been reported with Straumann implants in other peer-reviewed publications, including 10-year survival rates of 97 – 99 % in more than 600 patients1.

Brand matters!Because one implant failure is one too much.
