The presentation will address the increasing problem of peri-implantitis. One of the most common cause is loose screws that facilitate a micro-gap between the abutment implant interface creating a bacterial biofilm. The consequences of this micro-gap can lead to a lowering of Ph, inflammation, suppuration, and circumferential bone loss (saucerisation).  It is now apparent that retained cement (peri-cementitis) is also a potent initiator in peri-implantitis.  The presentation will illustrate the use of neither screws or cement in the use of Bicon’s  Integrated Abutment Crowns™.

Learning Objectives:  At the completion of this presentation, participants should be able to:

  1. Objectively assess the advantages and disadvantages of conventional implant systems
