Predicting peri‐implantitis incidence and implant failure via risk‐assessment and prognostication tools: A validation study

In this study, we followed 87 patients with 146 implants over time to test how well different tools can predict implant health and survival. We tested three tools, IDRA for predicting peri-implantitis, the KC system, and a new tool based on progressive bone loss for predicting implant survival. After 2 years with the implant crowns in place, we checked for cases of peri-implantitis. At the final follow-up (up to 8 years), the implant survival was assessed. We found that IDRA was not effective in predicting which implants developed peri-implantitis, even in high- and moderate-risk implants. In contrast, the KC tool was much more accurate, predicting implant survival in about 80% of cases. The PBL tool was also good in predicting implant survival, but slightly less accurate than the KC tool.
