Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a biodegradable implant, which uses a high shear mixer to mix and shape a biodegradable polymer melt and biodegradable ceramic particles at a temperature higher than the melting point of the biodegradable polymer; and an implant for bone regeneration comprising the biodegradable implant, formed by uniformly inserting biodegradable ceramic particles having a diameter of several hundred micrometers into the melt of a biodegradable polymer resin produced accordingly. 본 발명은 고전단혼합기를 이용하여 생분해성 고분자 용융물과 생분해성 세라믹 입자를 생분해성 고분자의 융점보다 높은 온도에서 교반하여 혼합하고, 성형하는 생분해성 이식체의 제조방법 및 이에 따라 제조된 생분해성 고분자 수지의 용융물에 수백 마이크로미터 직경의 생분해성 세라믹 입자들이 균일하게 삽입되어 성형된, 생분해성 이식체를 포함하는 골재생용 임플란트에 관한 것이다.
