PURPOSE: To provide a fixing plate for a jaw surface bone, the contour of which is complicated, a strong an d absorptive surgical clip and by forming the subject appliance from many absorptive polymers composed of a first and second couplings or absorptive mixture of first and second polymers, and containing the many first couplings or the polymers at a specified ratio. CONSTITUTION: An absorptive material formed of many first and second couplings, and a copolymer and a first polymer in a mixture is selected from glycollic acid ester coupling, lactic ester coupling and a mixture thereof. A second coupling of the copolymer and a second polymer in the mixture are selected from a group consisting of 1,3-dioxan-2-on coupling, 1,4-dioxan-2-on coupling and ε-caprolactam coupling. Many first couplings or the polymers exist at the ratio of 50mol% to 90mol% of the copolymer or the mixture. The polymer is a block or a graft copolymer, or a mixture and/or a copolymer of a homogeneous polymer. |
