Abstract
A method for treatment of periodontal disease is disclosed. The gingival tissue is separated from the tooth surface in an area where periodontal disease is present. A biocompatible, porous material such as expanded polytetrafluoroethylene capable of supporting ingrowth of gingival connective tissue and preventing apical migration of gingival epithelium is placed in a laminar relationship to a portion of the perimeter of the tooth surface. The gingival tissue is repositioned around the tooth and in contact with the porous material, with the porous material positioned between the gingival tissue and the tooth. Articles for the treatment of periodontal disease are also disclosed. One article comprises a first portion which is capable of supporting ingrowth of gingival connective tissue and preventing apical migration of gingival epithelium and a second portion which is impermeable to oral tissues and bacteria.
