骨重建技术的进步增加了在以前认为不适合的部位放置种植体的适应症。本临床研究评价了一种新的手术技术，用于治疗4例使用钛增强膜的患者的各种局部骨缺损。开发膜材料以在膜和骨表面之间保持大的保护空间，而不需要支撑装置。所有部位均顺利愈合，6至12个月后取出膜。没有发现残留缺损，导致颊部开裂部位的种植体暴露平均变化为8.2 +/- 2.3 mm，局部骨缺损部位的牙槽嵴增大5 - 6 mm。钛增强膜下的再生组织的质量表现为具有表面纤维层的骨结构。该纤维层在单独使用膜治疗的部位更明显，但软组织下的新骨量超过了补偿。结果表明，使用加强膜似乎是一种可行的替代方案，用于临床治疗非空间维持型种植体/骨缺损。建议进行进一步的临床和实验研究。
Advances in bone reconstructive techniques have increased the indications for implant placement in sites previously thought to be unsuitable. This clinical study evaluated a new surgical technique for the treatment of a variety of localized bone defects in four patients utilizing a titanium-reinforced membrane. The membrane material was developed to maintain a large protected space between the membrane and the bone surface without the need for a supportive device. Healing was uneventful in all sites, and the membranes were retrieved after 6 to 12 months. No residual defects were noted, resulting in an average change of implant exposure of 8.2 +/- 2.3 mm for sites with buccal dehiscences and from 5 to 6 mm ridge enlargement in localized bone defects. The quality of the regenerated tissue under the titanium-reinforced membrane appeared as bone structure with a superficial fibrous layer. This fibrous layer was more pronounced in sites treated with a membrane alone but was more than compensated by the quantity of new bone under the soft tissue. The results demonstrated that the use of a reinforced membrane appears to be a viable alternative for the clinical treatment of non-space-maintaining implant/bone defects. Further clinical and experimental investigations are recommended.
