Implant Surfaces and Peri-implantitis, from Surface to Suppuration

Peri-implant disease is a growing problem in implant dentistry today. Despite our best efforts to refine implant design and surface features the problem persists, and in some cases appears to be growing. As more and more implants are placed by clinicians of varying skill levels and clinical backgrounds the numbers of patients presenting with the disease is increasing.

Dental implant surfaces have evolved from the machined surfaces of the early Branemark implants, through to nano-featured surfaces with reported ‘bio-active’ features. This has led to more rapid and stronger osseo-integration and shorter treatment times. However, is there potential for the surface topography and chemistry to influence the initiation and treatment of peri-implant disease?

This informative lecture outlines the basic features of dental implant surfaces and the possible impact on the initiation and treatment of peri-implant disease, as well as our clinical decision making when treating an implant with peri-implantitis.

The lecture will also cover best practice for hygienists and routine maintenance.

Learning Objectives:

  • To understand what Sa values are and their significance in understanding roughness
  • To understand the histological differences between a tooth and an implant and its impact on disease progression and treatment
  • To know when to remove and when to decontaminate a surface
  • To learn about long term implant maintenance
