Filed:

Jun 29, 1993

Appl. No.:

8/084777

Inventors:

Richard L. Dunn - Fort Collins CO
Arthur J. Tipton - Fort Collins CO
George L. Southard - Fort Collins CO
Jack A. Rogers - Fort Collins CO

Assignee:

Atrix Laboratories, Inc. - Fort Collins CO

International Classification:

A61F 200

US Classification:

424426

Abstract:

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.

Abstract:

A polymeric controlled delivery system is provided for use in treating periodontal disease. The delivery system in a variety of forms is placed directly in the infected gingival tissue where the chemotherapeutic agent is slowly released into the tissue and into the infected periodontal pocket by means of the gingival crevicular fluid originating in the gingival tissue.

Assignee:

Atrix Laboratories, Inc. - Fort Collins CO

International Classification:

A61F 200

US Classification:

424426

Abstract:

The invention is directed to a composition composed of a thermoplastic or thermosetting polymer which is capable of forming a biodegradable and/or bioerodible microporous, solid or gelatinous polymer matrix. The matrix is useful as an implant in animals for enhancing regeneration of cells and tissue, such as bone and nerve cells, or for delivery of biologically-active substances to tissue or organs. The composition is administered to an implant site as a liquid. The invention also includes a method of preventing and treating disorders and diseases, such as bone or nerve growth disorders, or of altering body functions such as birth control, using the compositions and implants of the invention.
