Risk indicators for Peri-implantitis. A cross-sectional study with 916 implants.

Area of Science:

• Dental Implantology
• Periodontology
• Prosthodontics

Background:

• Peri-implantitis is a prevalent complication following dental implant placement.
• Identifying risk factors is crucial for preventing implant failure and managing patient outcomes.

Purpose of the Study:

• To identify systemic and local risk indicators associated with the development of peri-implantitis.
• To investigate the relationship between implant characteristics and peri-implantitis incidence.

Main Methods:

• A retrospective study involving 183 patients with 916 osseointegrated titanium implants in function for at least one year.
• Data collection included patient systemic conditions, implant characteristics, and clinical parameters.
• Statistical analysis, including logistic regression, was performed to determine risk factors.

Main Results:

• A history of periodontal disease increased peri-implantitis risk by 2.2 times.
• Cemented restorations showed a 3.6 times higher risk compared to screw-retained prostheses.
• Wear facets (2.4x) and full mouth rehabilitations (16.1x) were significant risk indicators.

Conclusions:

• Past periodontal disease, cemented prostheses, prosthetic wear facets, and full mouth rehabilitations are key risk indicators for peri-implantitis.
• Implant characteristics, such as diameter, length, and connection type, were not found to be associated with peri-implantitis.
