This clinical case report addresses the step-by-step of the application of a core-and-post system that uses a single resin composite material to fiber post cementation and core build-up in a maxillary left central incisor.
The literature reports several materials and methods for the restoration of endodontically treated teeth with coronal destruction that require an intra-radicular fiber post for the core build-up. The present case report describes a core-and-post or "monoblock" technique. A dual resin composite (Core-X Flow; Dentsply DeTrey) highly filled material and cement was used for luting the fiber post (Blue X-Post) and build-up the core structure in an easy application.
The "core-and-post" technique that uses a single material system protocol minimizes the material interfaces, steps of procedures, and chair-time in comparison to conventional techniques.
The use of different materials for post cementation and core build-up requires more steps, which increases the chair-time and number of interfaces among the materials. Since the "monoblock" technique uses only one material, it can streamline the clinical procedures, thus, saving time and materials. Moreover, techniques based on core-and-post systems are easily applied, versatile, and esthetics, and can be applicable to posterior and anterior teeth.
本临床病例报告介绍了在上颌左中切牙中应用核-桩系统的逐步过程,该系统使用单一树脂复合材料进行纤维桩粘结和核体构建。
文献报道了几种用于修复有冠部破坏的根管治疗牙的材料和方法,这些牙需要进行根管内纤维桩核体构建。本病例报告描述了一种核-桩或“整体式”技术。使用双树脂复合材料(Core-X Flow;Dentsply DeTrey)高填充材料和粘结剂来粘结纤维桩(Blue X-Post)并以易于应用的方式构建核体结构。
与传统技术相比,使用单一材料系统方案的“核-桩”技术可最大程度地减少材料界面、操作步骤和椅旁时间。
用于桩粘结和核体构建的不同材料需要更多的步骤,这增加了椅旁时间和材料之间的界面数量。由于“整体式”技术仅使用一种材料,因此可以简化临床操作程序,从而节省时间和材料。此外,基于核-桩系统的技术易于应用、用途广泛且美观,可适用于后牙和前牙。
