The restoration of endodontically treated teeth has been the focus of considerable controversy and empiricism. Time-tested methods have been highly successful in some respects, but failures are still apparent. The inherent causes of failure are rarely evaluated and the limitations of specific restorative systems are seldom identified. Regardless of the system, there should be a thorough understanding of the anatomy and biology of the dentin and root supporting the restoration on the part of the practitioner, because both endodontic and restorative procedures alter the hard tissues.
根管治疗后牙齿的修复一直是大量争议和经验主义的焦点。经过时间考验的方法在某些方面非常成功，但失败情况仍然明显。失败的内在原因很少得到评估，特定修复系统的局限性也很少被确定。无论采用何种系统，从业者都应该对支持修复体的牙本质和牙根的解剖结构及生物学特性有透彻的了解，因为根管治疗和修复操作都会改变硬组织。
