Periodontium-regenerative materials

摘要

A periodontium-regenerating material for the regenerative treatment of the periodontium consists of bio-degradable/absorable copolymers of lactide/ epsilon -caprolactone or lactide/glycolide having a weight-average molecular weight of 40,000 to 500,000 as well as a dynamic modulus of 5x107 to 5x109 dynes/cm2 and a elongation rate of 100 to 2,000 %, both measured at room temperature (25 DEG C.). Those copolymers may be used in the form of a sheet or film which may or may not be porous.
