Implant survival and success rates in patients with risk factors: results from a long-term retrospective study with a 10 to 18 years follow-up.

Abstract

The presence of a single risk factor does not imply a marked increase of failure risk. Among the analyzed factors, the one that proved to be the most dangerous was bruxism, even when presented as the only risk factor. Bruxism with load risk proved to be the most dangerous association (success rate 69.23%) and could be included among the absolute contraindications for implant treatment.
