| 摘 要： | 目的应用脱钙冻干异体骨（DFDBA）修复骨缺损，解决种植区的骨量不足问题。方法在种植外科中，将脱钙冻干异体骨用于19例种植区骨缺损患者，观察种植体动度、牙齿指数（GI）及x线改变等临床指标，评价其临床应用效果。结果19例植骨手术均获成功，无一例种植体周围炎发生，种植体初期稳定性良好。结论脱钙冻干异体骨既有一定的力学支持能力，又有骨诱导作用，且可塑性强。

| Abstract: | Objective To repair bone defect with demineralized freeze-dried bone (DFDBA) allo-grafts. Methods Nineteen cases of peri-implant bone defects were treated with DFDBA. Implant movement, GI and X-rays changes were recorded postoperatively to evaluate the clinical efficacy. Results During a period of 6-36 months follow-up,bone transplatation was successful in all 19 cases. No peri-implatitis occurred. All implants had good primary stabilities. Conclusion DFDBA has both mechanical resistance and osteoinductive capacity. It is a rather ideal bone replacement graft for peri-implant bone defect. |
