개선된 치과기구 및 폴리머 시트가 개시된다. 상기 치과 기구 및 폴리머 시트는, 약 1,000 MPa 내지 2,500 MPa의 모듈러스를 갖는("경질") 재료로 구성된 외부층들; 및 엘라스토머 재료 또는 약 50 MPa 내지 500 MPa의 모듈러스를 갖는("연질") 재료로 구성된 내부 코어;를 갖는 치과 기구를 제조하는데 유용하며, 이러한 치과 기구는 현재 사용가능한 재료 및 치과 기구에 비해 개선된 유연성 및 강도 및 더 우수한 착색 저항성(stain resistance)을 나타낸다. Improved dental appliances and polymeric sheets are disclosed. The dental appliances and polymeric sheets are useful for making dental appliances having outer layers comprised of a material having a modulus of from about 1,000 MPA to 2,500 MPA ("hard") and an inner core comprised of elastomeric material or materials having a modulus of from about 50 MPa to 500 MPa ("soft"), which exhibit improved flexibility and strength and better stain resistance than currently available materials and dental appliances.
