发明名称 METHOD AND ARTICLE FOR TREATING PERIODONTAL DISEASE
摘要 An article for treatment of periodontal disease is disclosed. In use, the gingival tissue is separated from a tooth surface in an area where periodontal disease is present. A biocompatible, porous material (22) 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. One preferred article comprises a first portion (22) which is capable of supporting ingrowth of gingival connective tissue and preventing apical migration of gingival epithelium and a second portion (24) which is impermeable to oral tissues.
