Prognostic indicators for surgical peri-implantitis treatment

Area of Science:

• Dental Implantology
• Periodontology
• Surgical Outcomes Research

Background:

• Peri-implantitis, a complication of dental implants, requires effective treatment strategies.
• Resective surgical treatment is a common approach for managing peri-implantitis.
• Identifying prognostic indicators is crucial for predicting treatment success and guiding clinical decisions.

Purpose of the Study:

• To identify prognostic indicators for the outcome of resective peri-implantitis treatment.
• To analyze pooled data from two randomized controlled trials on peri-implantitis treatment.
• To evaluate the influence of various factors on the success of surgical peri-implantitis management.

Main Methods:

• Pooled data analysis of 74 patients (187 implants) undergoing resective surgical treatment for peri-implantitis.
• Primary outcome: treatment failure after 12 months.
• Multilevel univariable and multiple logistic regression analyses were performed to identify prognostic indicators.

Main Results:

• Treatment failure occurred in 57% of implants and 67% of patients after 12 months.
• Significant prognostic indicators for failure included "order of inclusion" and mean bone loss at baseline.
• Post hoc analysis identified smoking and mean bone loss at baseline as significant predictors, with plaque and pocket depth also showing associations.

Conclusions:

• Surgical team experience, indicated by "order of inclusion," influences peri-implantitis treatment outcomes.
• Mean bone loss at baseline and smoking are key prognostic indicators for treatment success.
• Early diagnosis and management of behavioral factors like smoking are critical for successful peri-implantitis treatment.
