本标准规定了聚合物基冠桥材料的分类和要求,同时也规定了与这些标准要求相应的试验方法。
本标准适用于在技工室制作与金属表面接触或不接触的永久贴面或前牙冠的聚合物基冠桥材料。
本标准也适用于生产厂声称不需要借助金属基底材料上的突起或网格固位即可与金属基底材料粘接的聚合物基冠桥材料。
本标准不适用于直接牙体修复中所用的冠、贴面或修补的聚合物基材料,也不适用于那些用于后牙承力区的材料。

Scope

This standard specifies the classification and requirements for polymer-based crown and bridge materials, and also specifies test methods corresponding to the requirements of these standards. This standard applies to polymer-based crown and bridge materials for permanent veneers or anterior crowns made in the laboratory with or without contact with metal surfaces. This standard also applies to polymer-based crown and bridge materials that the manufacturer claims can be bonded to the metal base material without the need for protrusions or mesh retention on the metal base material. This standard does not apply to polymer-based materials for crowns, veneers or restorations used in direct dental restorations, nor to those used in the load-bearing areas of posterior teeth.
