标准范围

本文件规定了聚合物基复合材料可加工毛坯在铣削工艺方面的特性，并提供了解决这些材料特有的临床问题的测试方法。此外，本文件规定了包装和材料上描述的项目，以及使用说明中包含的描述。本文所涵盖的基于聚合物的复合可加工坯料是用于通过铣削工艺制造永久性牙科修复器具(例如单个牙冠或嵌体)的坯料。它们不包括允许从一个坯料或临时使用的材料制造两个或更多个牙冠或牙桥单元的大尺寸坯料（例如盘）。

This document specifies the characteristics of polymer-based composite machinable blanks with respect to the milling process and provides the test methods that address the clinical issues specific to those materials. In addition, this document specifies the items to be described on the packaging and materials, as well as descriptions to be included in the instructions for use.

The polymer-based composite machinable blanks covered in this document are blanks that are used for fabricating permanent dental restorative appliances (e.g. single crowns or inlays) by milling processes. They do not include large-sized blanks (e.g. discs) that allow for the fabrication of two or more units of crowns or bridges from one blank or materials for temporary use.
