One challenged associated with the placement of maxillary resin-bonded fixed partial dentures (RBFPDs) that include anterior abutments is creating an effective preparation design to ensure mechanical retention of the dentures and anterior-guided occlusion. This article presents a methodical preparation design for anterior abutments of RBFPDs. One innovative feature involves extending the reduction to part of the occlusal wear facets. This design makes it possible to preserve the patient's innate occlusal function and to hold the retainer firmly by means of applied occlusal force.
与包含前牙基牙的上颌树脂粘结固定局部义齿（RBFPDs）的放置相关的一个挑战是创建一种有效的预备设计，以确保义齿的机械固位和前导性咬合。本文介绍了一种用于RBFPDs前牙基牙的系统预备设计。一个创新特点是将牙体预备扩展至部分咬合磨耗面。这种设计能够保留患者固有的咬合功能，并通过施加的咬合力将固位体牢固固定。
