An extensive review of the published literature has revealed a wide divergence of opinion regarding the suitability of different post systems for endodontically treated teeth. As a result, the dentist has no clear guidelines concerning the selection of suitable post systems that will provide adequate retention while minimizing subsequent root fracture.
This study formulated, through the literature search, a set of guidelines to assist the dentist in selecting an endodontic post system that would optimize retention while limiting root fracture.
For most clinical situations, the literature indicates that a passive parallel-sided post will, in the hands of the average practitioner, allow the dentist to successfully restore most endodontically treated teeth.
对已发表文献的广泛回顾显示，对于不同桩系统用于根管治疗牙齿的适用性，存在广泛的意见分歧。因此，牙医在选择合适的桩系统时没有明确的指导原则，这些桩系统既要提供足够的固位力，又要使后续牙根折裂的风险降至最低。
本研究通过文献检索制定了一套指导原则，以帮助牙医选择一种根管桩系统，该系统既能优化固位力，又能限制牙根折裂。
对于大多数临床情况，文献表明，在普通从业者手中，被动平行边桩能使牙医成功修复大多数根管治疗后的牙齿。
