The primary objectives of successful prosthetic rehabilitation are to provide function, esthetics and comfort to the patient. Combination prosthesis is one which is supported by both natural teeth and implant. The periodontal ligament and osseointegrated interface distribute force differently to the supporting bone. Therefore problems can develop when tooth and implants are combined in the same prosthesis. However, clinicians can apply biomechanical principles, to negate the deleterious leverages exerted by the fixed prosthesis by using non rigid components and to equalize the stress applied by the prosthesis on implant and teeth. A case of partially edentulous situation was rehabilitated successfully with a combination of prostheses. Maxillary arch was restored to function with crowns, fixed dental prosthesis and with an extra coronal castable attachment prosthesis and the mandibular arch with a combination of tooth and implant supported attachment prosthesis. The clinical and laboratory steps for the fabrication of these prostheses are explained in this report.
成功的修复体康复的主要目标是为患者提供功能、美观和舒适感。联合修复体是一种由天然牙和种植体共同支持的修复体。牙周韧带和骨结合界面将力以不同方式传递至支持骨。因此，当牙齿和种植体联合在同一修复体中时可能会出现问题。然而，临床医生可以应用生物力学原理，通过使用非刚性部件来消除固定修复体施加的有害杠杆作用，并使修复体施加在种植体和牙齿上的应力均衡。一例部分牙列缺损情况通过联合修复体成功修复。上颌牙弓通过冠修复、固定义齿以及一个冠外可铸造附着体修复体恢复功能，而下颌牙弓采用牙和种植体支持的附着体修复体联合修复。本报告解释了这些修复体制作的临床和实验室步骤。
