title: Guided bone regeneration around exposed implants: a new bioresorbable device and bioresorbable membrane pins.
abstract: This article presents the principles and the clinical procedure of utilizing a new bioresorbable collagen barrier device, bioresorbable membrane pins, and a new bone substitute for bone regeneration around exposed implants. Three cases are used to illustrate the clinical procedure. In all three cases, the regeneration of bone around the implants was successful, and upon clinical examination the newly regenerated material resembled natural bone. Histologic data regarding the new bioresorbable collagen barrier itself and the time range in which the collagen device functioned as a barrier are still lacking, and the studies are currently being conducted. The learning objective of this article is to introduce a combination of options available for successful regeneration of bone around the implants and avoiding the second-stage surgery.
