What is the Role of Endodontic Predisposing Factors in Early Implant Failure? Selen Nihal Sisli, Zafer Ozgur Pektas
Posted on 2/4/2021 by Greg Kammeyer
This paper was designed to explore a possible relationship between early implant failure and an adjacent root canal tooth and /or a tooth with a periapical lesion.
Eight hundred and ten implants scored according to the implant failure before abutment connection, adjacent root canal-treated teeth, adjacent teeth without root canal, no adjacent teeth, adjacent teeth with periapical lesion, extraction of teeth with periapical lesion, and or root canal teeth before implantation.
The time from the root canal of adjacent teeth to implant placement was categorized into 5 groups: less than four weeks after implantation, 4-12 weeks before implantation, at least 12 weeks before implantation, within 4 weeks after implantation, and at least 4 weeks after implantation. Among the endodontic predictors, a prior periapical lesion on the tooth extracted was associated with an increased risk of Early Implant Failure.
My note: They didn't note a statistically significant difference.
Furthermore, Early Implant Failure was more likely to occur when the root canal tooth of an adjacent tooth was performed within 4 weeks of implantation.
