Healing patterns associated with an Atrisorb barrier in guided tissue regeneration.

The current guided tissue regeneration clinical technique uses synthetic membranes at the time of the surgical procedure to separate the gingival and periodontal tissue components. These membranes are tied to the tooth surface and have to be ++removed during a second surgical procedure. The material Atrisorb is currently under development as a guided tissue regeneration barrier in Class II furcation defects. This material is applied directly over the furcation defect and is not tied to the tooth surface. Because of its biodegradability, Atrisorb does not have to be removed. A case study is presented.
