In the posterior partially edentulous jaw, implants may be used to supplement existing natural dentition. Frequently, the maxillary sinuses and the mandibular nerve preclude the fabrication of freestanding implant-retained prostheses. However, if an implant and a natural abutment are combined, a fixed prosthesis can be fabricated, restoring the arch into the premolar area. The histories of three patients with attachments connecting implant-retained ceramotitanium crowns with crowns on natural abutments are described. A design for a rigid custom-made attachment for the Brånemark system, using standard components with a machine-duplication, spark-erosion technique, is suggested.
在后部部分牙列缺失的颌骨中，种植体可用于补充现有的天然牙列。上颌窦和下颌神经常常会妨碍制作独立的种植体固位修复体。然而，如果将种植体与天然基牙相结合，就可以制作固定修复体，将牙弓恢复到前磨牙区。本文描述了3例患者的病例，这些患者的种植体固位的烤瓷钛合金冠与天然基牙上的冠之间采用了附着体连接。文中还提出了一种针对Brånemark系统的刚性定制附着体的设计方案，该方案使用标准部件，采用机械复制、电火花加工技术。
