A Classification System for Peri-implant Diseases and Conditions

Area of Science:

• Dental Implantology
• Periodontology
• Biomaterials Science

Background:

• Peri-implant bone levels are affected by various pathological and non-pathological factors.
• Current peri-implantitis classifications describe disease progression or tissue involvement (mucositis/peri-implantitis) but lack etiological basis.

Purpose of the Study:

• To identify the diverse etiologies of peri-implantitis.
• To establish a novel classification system for peri-implantitis grounded in its pathogenesis.

Main Methods:

• Literature review and analysis of existing data on peri-implantitis causes.
• Development of a new classification framework based on identified etiological factors.

Main Results:

• Biofilm emerged as the predominant cause of peri-implant bone loss.
• Other significant etiologies identified include iatrogenic factors, exogenous irritants, lack of keratinized tissue, and extrinsic pathology.
• The study highlights that different etiologies may necessitate distinct therapeutic approaches.

Conclusions:

• A new etiological classification system for peri-implantitis is proposed.
• This classification facilitates accurate diagnosis by pinpointing the root cause of peri-implant disease.
• Understanding the etiology is crucial for tailoring effective treatment strategies for peri-implantitis.
