Abstract
A method and surgical implant article for enhancing the regeneration of periodontal connective tissue at tooth root surfaces exposed by periodontal surgery wherein the exposed root surfaces are covered with a surgical implant article which is a membrane which excludes contact between the root surfaces and gingival epithelium and gingival connective tissue but permits migration to the root surfaces of PDL cells, the membrane being constructed of a non-toxic, nonimmunogenic, bio-absorbable material.
