Composite for treating periodontal disease |
摘要 |
Absorbable composite materials are described that comprise a collagen matrix reinforced with a layer of a bioabsorbable polymer. A chemotherapeutic agent is dispersed in the composite material. The layer of bioabsorbable polymer is preferably a woven, nonwoven or knitted mesh layer of a synthetic bioabsorbable polymer such as polylactic/polyglycolic acid copolymer, or oxidised regenerated cellulose. The chemotherapeutic agent may be an antibiotic, an anaesthetic, an antiseptic or an anti-inflammatory. Strips of the composite material are inserted into the periodontal pocket, where they are retained in place and provide effective sustained release of the chemotherapeutic agent over an extended period. |
