Prognostic tool: Prediction of 1 year outcome after peri-implant disease
This tool is intended to provide prognosis of implants diagnosed with peri-implant disease.
The purpose of the tool is to:
A) Provide clinicians a one year ahead probability of favorable or unfavorable prognosis for implants diagnosed with peri-implant disease based on the implant characteristics. The determination of the prognostic factors can be performed easily and reliably during follow-up appointments.
- Favourable prognosis includes remission of the disease with no signs of active peri-implant disease.
- Unfavourable prognosis is considered when the implant remains with signs of active peri-implant disease, or implant removal.
B) Provide patients with a graphical information on outcome expectations and education for better self-care decisions.
The limitations of the tool rely on the short follow-up time providing an insight of the prognosis and only being applicable to Nobel Biocare implants. The tool should not be used to evaluate implants whose marginal bone level extends to the apical third, as in these cases it already represents a failed implant.
The tool should not be used for deciding to keep or extract the implant. Further skills that are needed by the clinician include solid knowledge of peri-implant pathology’s epidemiology, treatment (including non-surgical and surgical) and maintenance. The tool was developed by a research group led by Professor Miguel de Araújo Nobre and validated in 2019 [1].
