纯钛膜在种植外科中应用效果的初步研究

目的 评价无孔纯钛膜治疗种植体周围骨缺损的临床效果，并探讨其应用技巧。方法 81例患者的92颗种植体周围骨缺损均采取自体碎骨及Bio-Oss人工骨移植充填后，国产无孔纯钛膜覆盖治疗，术后6～10个月行种植Ⅱ期手术，同时取出钛膜。结果 5例(6颗种植体)发生种植术后软组织瓣早期裂开或穿孔，钛膜外露且早期取出；其余76例软组织瓣愈合良好，原骨缺损完全骨性修复。结论 钛膜有良好的生物相容性，有效地防止移植的骨代用品移位、纤维结缔组织长入，其塑形性好，能维持较大的骨再生修复空间，骨生成量大。

Clinical study of pure titanium membranes in oral implant surgery

Objective To evaluate predictability and treatment outcome of the pure titanium membranes in bone defects around endosseous implants Methods 81 patients and 92 dental implants were included in this study The defects around implants were filled with bone grafts and Bio Oss, and then covered by titanium membranes 6 10 months later,all of the membranes were removed Results 5 patients showed complications in soft tissue healing with exposure of the membranes Bone defects around 89 implants were successfully covered with new regenerated bone Conclusions Pure titanium membranes show excellent biocompatibility, exhibit good mechanical properties, avoid grafts displacement, ingrowth of connective tissue and contour collapse
