摘　　要：目的:种植体植入血管化髂骨修复下颌骨缺损已成为一种常规治疗方法。本研究对一组ITI种植体即刻植入血管化髂骨后的效果进行评价。方法:对2000～2004年间12例患者共36枚ITI种植体植入血管化髂骨的情况进行研究。髂骨瓣移植完成即刻种植体植入,3～5个月愈合期后进行修复负载。结果:种植体植入髂骨后初期稳定性良好,经1年观察,垂直骨吸收<1m m,进入稳定状态。在观察期间无种植体失败。结论:血管化髂骨是下颌骨缺损修复安全的种植床。种植体支持的固定义齿和覆盖义齿修复,是下颌骨缺损可靠的修复方法。PURPOSE: Vascularized iliac bone graft combined implantation has become a routine procedure in the functional reconstruction of mandibular defects. The aim of this study was to assess the clinical outcomes of the implants immediately placed into the vascularized iliac bone grafts. METHODS: In this study, 12 consecutive patients with 36 ITI dental implants who had reconstruction of mandibular defect between 2000 and 2004 were presented. All implants were inserted immediately after bone grafting and loaded after 3 to 5 months of submerged healing. RESULTS: In general, a primary stability for implants placed in vascularized iliac bone grafts were achieved. After 1 year of observation the mean vertical bone loss was less than 1mm. There was no implant failure in the observation period. CONCLUSION: The vascularized iliac bone grafts are safe implant-bearing areas and allows a reliable and predictable restoration with dental implants. Implant-supported bridges and overdentures can be used in this procedure.
