发明名称 BIOABSORPTIVE PROSTHETIC MATERIAL FOR REGENERATING PERIODONTIUM
摘要 <p>PURPOSE: To provide a fixing tool which can support or fix a bioabsorptive protective film for regenerating periodontium by implanting together with the bioabsorptive protective film in a bone failure site or a site where bone neogenesis is needed of periodontium. CONSTITUTION: A prosthetic material 5 for regenerating periodontium formed by integrating a fixing tool wherein a bioabsorptive material consists of a polymer of lactic acid or glycolic acid and the degree of polymn. is in a range of 2,000-5,000 with a protective film is used for a method for introductive regeneration of the periodontium (GTR) in periodontics region. In this instance, as a bioabsorptive protective film 2 protects a diseased part from being invaded with gingival binding tissue cells and epithelial cells and a space for regeneration of a bone can be ensured by a bio-absorptive fixing tool 3, in a wide range bone failure site 1, regeneration/neogenesis of the bone can be accelerated by assisting introduction of osteoblast. Therefore, as the prosthetic material has proper decomposition period, hardness and strength and it is unnecessary to remove the fixing tool and the protective film after surgery, the surgery can be surely and easily performed.</p>
