目的：对比骨引导天然煅烧骨与Bio-Oss应用于拔牙后牙槽嵴保存的效果。方法：280例患者单颗牙拔除后，随机分为2组，将骨引导天然煅烧骨和Bio-Oss各植入140例拔牙窝中，塑形后均用Bio-Gide生物膜覆盖，颊侧黏骨膜翻瓣、滑行缝合、封闭拔牙创，并在术后第1周、12周、24周复查，拍摄全口曲面断层片及CT，评价2种植骨材料牙槽嵴保存的效果。结果：2组的大体观察均显示出了较好的结果，无感染及排斥反应。12周及24周影像学结果显示2组牙槽嵴的宽度和高度均得到了较好的保存，组间比较无统计学差异（P＞0．05）。结论：2种植骨材料均能有效地保存拔牙后牙槽骨的骨量。

Objective:To compare the outcomes of guide bone regeneration by calcined bovine bone and Bio-Oss graft material in alveolar ridge preservation after tooth extraction.Methods:280 patients were divided into two groups randomly.Each patient had single tooth extracted.The sockets were filled with calcined bovine bone in 140 patients and Bio-Oss graft in another 140 patients. After shaping,all the sockets were covered with Bio-Gide membrane.Buccal mucoperiosteal flap was released and sutured to close the alveolar sockets.The patients were regularly examined at the 1st,12th and 24th week after surgery.Physical examination and X-ray evaluation were applied to compare the outcomes of the two materials in alveolar ridge preservation.Results:No infection and re-jection occurred.The radiographic results showed the width and height of the alveolar bone were preserved well at the 12th and 24th weeks.No statistically difference was found in the two groups at the 1st and 24th weeks(P>0.05).Conclusion:The two graft ma-terials can effectively preserve alveolar bone after tooth extraction.
