BIODEGRADABLE SYSTEM FOR REGENERATING THE PERIODONTIUM |
| 摘要 |
Methods are described for assisting the restoration of periodontal tissue in a periodontal pocket and for retarding migration of epithelial cells along the root surface of a tooth. The methods involve placement of an in-situ forming biodegradable barrier adjacent the surface of a tooth. The barrier is microporous and includes pores of defined size. The barrier can include a biologically active agent.
