Endodontically treated teeth present a myriad of problems because of coronal destruction from caries, previous restorations, and coronal access. Previously, a post was considered necessary to strengthen a tooth and to resist intraoral forces. However, recent research has indicated that not all endodontically treated teeth require a post, core, and crown. Each clinical situation must be evaluated and the need for a post and/or the appropriate post determined. The recent introduction of a carbon-fiber post may reduce some of the problems inherent with metal posts. Proper placement, advantages, and disadvantages are discussed.
由于龋病、先前的修复体以及髓腔入口导致的牙冠破坏，经过根管治疗的牙齿存在诸多问题。以前，人们认为需要桩来增强牙齿并抵抗口腔内的力量。然而，最近的研究表明，并非所有经过根管治疗的牙齿都需要桩、核和冠。必须对每种临床情况进行评估，并确定是否需要桩和/或合适的桩。最近引入的碳纤维桩可能会减少金属桩固有的一些问题。本文将讨论其正确放置方法、优点和缺点。
