In situations of moderate residual ridge resorption where multiple tooth replacement is needed, and where the patient desires a fixed implant-supported restoration, it is challenging to design a pontic-tissue interface. The semiconvex multiple pontic design described in this article, with its mucosal contact exerted with moderate pressure, is proposed to circumvent the problems encountered with the plaque accumulation, maintenance conditions, phonetics, and compromised esthetics frequently encountered in these patients. The use of a screw-retained, implant-supported restoration is also emphasized to allow for sufficient tissue contact during placement of the prosthesis and for prosthesis retrievability for maintenance or technical reasons.
在中度剩余牙槽嵴吸收的情况下，需要进行多颗牙齿替换，且患者希望获得固定种植体支持的修复体，此时设计桥体-组织界面具有挑战性。本文介绍了一种半凸形状的多桥体设计，黏膜接触施加中等压力，旨在避免这些患者常出现的菌斑积聚、维护条件、语音和美观受损等问题。还强调使用螺丝固位的种植体支持修复体，以便在放置义齿时能够充分接触组织，并在出于维护或技术原因需要取出义齿时能够取出。
