Definition
Temporary restoration
A prosthesis or restoration placed for a limited
period, from several days to several months,
which is designed to seal the tooth and
maintain its position until a permanent
restoration will replace it.
（From Jablonski, Dictionary of Dentistry, 1992）
暂时性修复：
从牙体预备取模后到最终修复体完成期间的临时修复体。

PARTIAL-COVERAGE RESTORATIONS
定 义
(Definition)
覆盖于部分牙体表面的固定修复体
（PARTIAL-COVERAGE RESTORATIONS）
只能用金属制作
保留完整的唇颊面
An extracoronal metal restoration that covers only
part of the clinical crown is considered to be a partial veneer crown. It can also be referred to as a
partial-coverage restoration.
