Abstract
A bioresorbable device for use in regeneration of at bone and/or tissue in either a bone void or a tissue deficiency is provided. A primary embodiment is a bioresorbable periodontal barrier for use in regeneration of a periodontal bone and/or tissue in either a gingival pocket adjacent to a patient's tooth or an edentulous area. The bioresorbable periodontal barrier includes a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding periodontal tissue growth, and a bioresorbable hardening agent pre-impregnated in the membrane. The membrane is formed to a desired shape and the hardening agent is activated to harden so that the membrane retains the desired shape. A method of assisting bone and/or tissue regeneration in either a bone void or tissue deficiency is also provided. A primary embodiment is a method of assisting and guiding periodontal bone and/or tissue regeneration in a gingival pocket adjacent to a patient's tooth or in an edentulous area. The method includes implanting a barrier over the gingival pocket, forming the membrane into a desired shape which covers the gingival pocket, and allowing the periodontal bone and/or the periodontal tissue to regenerate into the enclosed gingival pocket.
