Topographical aberrations in a residual edentulous ridge often prevent establishment of a satisfactory pontic/ridge relationship. An improved technique is described for predictable augmentation of localized alveolar-ridge deficiencies. Results are reported from 21 cases involving 26 sites. All 14 sites using fibrous connective tissue grafts demonstrated shrinkage, although an improvement in residual ridge contour was obtained. Hydroxylapatite implant material was placed in 12 sites with shrinkage seen in only two sites. Advantages, requirements for success and technical considerations of the improved technique are discussed.
剩余无牙颌牙槽嵴的形态异常常常妨碍建立令人满意的桥体/牙槽嵴关系。本文描述了一种用于可预测性增加局限性牙槽嵴缺损的改良技术。报告了21例涉及26个部位的结果。使用纤维结缔组织移植的所有14个部位均出现了收缩，尽管剩余牙槽嵴轮廓得到了改善。在12个部位植入了羟基磷灰石种植材料，仅在2个部位出现了收缩。讨论了改良技术的优点、成功的要求和技术要点。
