Guided tissue regeneration using a bioresorbable matrix barrier.

Bioresorbable barrier material, used in guided tissue regeneration, changes the conventional two-stage surgery to a single-step procedure. This article presents a general surgical protocol for application of a bioresorbable matrix barrier (Guidor AB, Huddinge, Sweden). Three case reports are used to illustrate the surgical treatment of a Class II furcation defect, an intrabony defect, and a recession type defect. The learning objective of this article is to enhance the knowledge of surgical procedures and bioresorbable barrier membranes available.
