Peri-implantitis and Severity Level

Area of Science:

• Dental Implantology
• Periodontology
• Oral Health Research

Background:

• Peri-implant diseases pose a significant challenge in implant dentistry.
• Current diagnostic criteria for peri-implant diseases lack standardization, leading to variability in reported prevalence.
• Understanding the prevalence and subclassification of peri-implantitis is crucial for effective management.

Purpose of the Study:

• To determine the prevalence of peri-implant diseases in a cohort of dental implant patients.
• To subclassify peri-implantitis based on varying radiographic and clinical parameters.
• To highlight the impact of different diagnostic thresholds on peri-implantitis prevalence rates.

Main Methods:

• A cross-sectional study involving 200 patients with 655 dental implants.
• Clinical measurements and radiographic evaluation of marginal bone levels were performed.
• Peri-implantitis was subclassified using marginal bone loss and probing depth severity levels.

Main Results:

• High prevalence of peri-implant diseases: 69.5% on subject basis and 60.4% on implant basis diagnosed with peri-implantitis.
• Prevalence of peri-implantitis varied from 10.0% to 31.0% depending on the applied diagnostic criteria.
• Subgingival restoration margins were common in implants with peri-implant mucositis (70.6%) and peri-implantitis (44%).

Conclusions:

• The prevalence of peri-implantitis is highly dependent on the diagnostic criteria used, ranging from 10% to 31%.
• The absence of universally accepted diagnostic criteria hinders accurate reporting of true disease prevalence.
• Further research is needed to establish standardized diagnostic guidelines for peri-implant diseases.
