Guided tissue regeneration around dental implants: three case reports

This article demonstrates the use of guided tissue regeneration (GTR) principles for regeneration of bone tissue in jaw bone defects associated with dental implant placement. The learning objective of this article is the technique of bone tissue regeneration using the barrier membranes. Three cases are presented to illustrate the procedure. In all of them, the barrier membrane was used to cover the surgical site after the placement of dental implants and bone grafts.
