关于根管治疗牙齿修复的临床概念目前尚不清楚,并且由于缺乏可靠的经验数据,通常基于猜想。发表的意见的多样性令人困惑,可能导致治疗选择不够理想。是否需要职位也正在出现辩论。本文的目的是以循证原则组织这一主题,并为牙科医生提供有关前磨牙和磨牙修复治疗的明确指南。提交了两份临床报告,举例说明不同的临床情况。第一个病例强调了牙髓治疗磨牙的保守修复,保持足够数量的健康残留组织,并且仅用修复材料覆盖尖端,健康的牙本质无法维持。在第二种情况下,事实上,前磨牙被龋齿病理严重损坏,这意味着有必要使用销来固定复合材料,尖端被完全覆盖。根据这两个临床报告和文献综述,阐述了纤维桩应用的概念。通过手和MEDLINE进行搜索,以确定经同行评审的有关重建经牙髓治疗的后牙的文章。共审查了1967年至2008年之间发表的70篇文章。
The clinical concepts regarding the restoration of root canal treated teeth are not clear today and often based on conjecture due to a lack of sound empirical data. The diversity of published opinions is confusing and may lead to less-than-optimal treatment selections. There is also emerging debate whether or not a post is necessary. The purpose of the present article is to organize this topic in evidence-based principles and provide dental practitioners with clear
guidelines about restorative therapy for premolar and molar teeth. Two clinical reports are presented, to exemplify the different clinical situations. The first case highlights a conservative restoration of an endodontically treated molar, maintaining an adequate quantity of healthy residual tissue and only covering the cusp with restoration material, which was not sustained by healthy dentin. In the second case, the fact that the premolar was so badly damaged by carious pathology meant that it was necessary to use a pin to anchor the composite material, and the cusp was covered completely. Based on the two presented clinical reports and a literature review, the concept of fiber post application is explained. Searches by hand and MEDLINE were employed to identify peer-reviewed articles on reconstruction of endodontically treated posterior teeth. A total of 70 articles published between 1967 and 2008 were reviewed.
