In some patients, lack of bone at a desired fixture site has resulted, by necessity, in the placement of endosseous implants in less than favorable locations. The principles of guided bone regeneration can be used to restore lost alveolar bone and permit the placement of implants at more ideal locations, or to provide a more favorable ridge form to support a removable prosthesis. The advantages of a two-stage technique involving bone grafting followed by a healing period prior to implant placement are discussed. Different methods of membrane tenting to provide space for bone growth are illustrated by three case reports. Evidence of bone augmentation is provided by computed tomography.
在一些患者中，由于所需种植体植入部位缺乏骨组织，不得已将骨内种植体植入了不太理想的位置。引导骨再生的原则可用于恢复缺失的牙槽骨，使种植体能够植入更理想的位置，或提供更有利的牙槽嵴形态以支持可摘义齿。本文讨论了两阶段技术的优点，该技术包括骨移植，然后在植入种植体之前有一个愈合期。三个病例报告说明了为骨生长提供空间的不同膜撑开方法。计算机断层扫描提供了骨增量的证据。
