When using an introcoronal precision attachment in a combined Fixed and Removable Prosthodontic case, the retention and appearance can be greatly improved. When taking into consideration these advantages one must not forget the disadvantages and possible violation of the biological principles of tooth preparation. Because in order to obtain a restoration with adequate contours it is necessary to reduce a significant amount of tooth structure. In this case the attachment is used in a catelever pontic avoiding any excessive tooth reduction. In metal-ceramic restorations it is important that a glazed surface be achieved upon completion because it enhances material strength and reduces plaque retention. This clinical report presents a step-by-step procedure using an intra-pontic attachment as a retainer for a removable partial denture. The procedural sequence assures optimal marginal integrity and glazed porcelain surfaces upon completion. A post-solder technique is recommended to assemble multi-abutment metal ceramic fixed partial dentures.
在固定-可摘联合修复病例中使用冠内精密附着体时，固位力和美观性可得到显著改善。在考虑这些优点时，不能忽视其缺点以及可能违反牙体预备生物学原则的情况。因为为了获得具有适当外形的修复体，有必要大量磨除牙体组织。在此病例中，附着体用于悬臂桥体，避免了过多的牙体磨除。在金属烤瓷修复体中，完成后获得光滑表面很重要，因为这可增强材料强度并减少菌斑附着。本临床报告介绍了使用桥体内附着体作为可摘局部义齿固位体的分步操作程序。该操作步骤可确保完成后获得最佳的边缘完整性和光滑的瓷表面。建议采用焊后技术来组装多基牙金属烤瓷固定局部义齿。
