Proper restoration of endodontically treated teeth is a frequent challenge to many clinicians. The majority of restorations are using various types of vertical support that can be placed in teeth, these include different prefabricated post systems as well as cast posts and cores. Less emphasis, unfortunately, has been placed on the materials utilized for final build up. Unless the tooth being treated undergoes minimal loss of tooth structure some from of augmentation will be necessary to increase the tooth strength and provide adequate support and retention for the final cast restoration. It is generally accepted that the ideal methods of corono-radicular buildup for nonvital teeth is a properly fabricated cast post and core.
对许多临床医生来说，正确修复经过根管治疗的牙齿是一项常见的挑战。大多数修复采用各种可放置在牙齿中的垂直支撑物，这些包括不同的预成桩系统以及铸造桩核。遗憾的是，人们较少关注用于最终堆塑的材料。除非所治疗的牙齿牙体组织损失最小，否则某种形式的增强是必要的，以增加牙齿强度，并为最终的铸造修复体提供足够的支撑和固位。一般认为，对于无活力牙齿，理想的冠根堆塑方法是制作精良的铸造桩核。
