Abstract

Peri-implantitis is a complex and increasingly prevalent biological complication following dental implant therapy. Characterized by inflammation and progressive loss of supporting bone around osseointegrated implants, peri-implantitis poses significant challenges to long-term implant success. While its clinical management draws on foundational principles from periodontal therapy, key anatomical and pathological distinctions between natural teeth and implant-supported structures necessitate tailored surgical strategies.

This lecture will explore the biological similarities and differences between peri-implant and periodontal tissues and how they impact the surgical management of peri-implantitis. This includes the regenerative and resective surgical techniques with an emphasis on the role of implant surface decontamination, defect morphology, and the selection of biomaterials in regenerative approaches.

Learning Objectives

• Understand the differences between the periodontal and peri-implant tissues
• Appreciate the differences in periodontal and peri-implantitis defects
• Understand how the differences affect flap design and surgical execution 
• Understand the challenges in implant surface decontamination 
• Discuss the biomaterial selection for managing peri-implantitis
