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。
Definition Transitional restoration（过渡性修复） Help make a diagnosis Diagnostic restoration Aesthetic changes Occlusal changes Periodontal changes Temporary restoration Treatment restoration Help make the best treatment plan
What’s the differents? ？ RCT+crown：pulp devitalization subfissure teeth, no spontaneous pain ？ Crown：endodontitis /apical paradentitis spontaneous pain: RCT OB half a year/ one year Temporary crown no spontaneous pain: permanent crown Provisional restoration 暂时性修复（时间角度） Treatment restoration 过渡性修复（作用角度）
