目的 以不同方式在拔牙后牙槽窝中植骨,对槽窝位点保护效果,探寻合理的牙槽窝保护方式.方法 选择2条杂交犬,拔除下颌P2、P3、P4前磨牙近中根.在拔牙窝中分别植入回收碎骨屑、羟基磷灰石以及两者不同比例的混合物.术后8周、12周时行影像、组织学检测.结果 植入人工骨比例越高,人工骨残余率越高.12周植入75％骨屑和25％人工骨组新骨形成率为(55.3±5.6)％,8周时为(45.5±7.2)％,均高于其他组(P＜0.05).结论 拔牙后牙槽窝即刻植入回收骨屑和不同比例羟基磷灰石混合骨可有效保护牙槽窝位点,75％碎骨屑和25％羟基磷灰石组植骨方式,牙槽窝骨量保护效果最好.
目的 以不同方式在拔牙後牙槽窩中植骨,對槽窩位點保護效果,探尋閤理的牙槽窩保護方式.方法 選擇2條雜交犬,拔除下頜P2、P3、P4前磨牙近中根.在拔牙窩中分彆植入迴收碎骨屑、羥基燐灰石以及兩者不同比例的混閤物.術後8週、12週時行影像、組織學檢測.結果 植入人工骨比例越高,人工骨殘餘率越高.12週植入75％骨屑和25％人工骨組新骨形成率為(55.3±5.6)％,8週時為(45.5±7.2)％,均高于其他組(P＜0.05).結論 拔牙後牙槽窩即刻植入迴收骨屑和不同比例羥基燐灰石混閤骨可有效保護牙槽窩位點,75％碎骨屑和25％羥基燐灰石組植骨方式,牙槽窩骨量保護效果最好.

Objective To evaluate the osteogenesis effect in the extraction socket preservation with different bone materials.Methods The mesio-roots of premolars were extracted from the mandibules in 2 dogs.In the extraction sockets,Different bone materials were implanted.The radiographic and histological observations were performed at 8th and 12th weeks after surgery.Results The bone density of extraction socket specimens implanted with the same material at 12th week was stronger than at 8th week.The percent of newly formed bone in the extraction sockets implanted with 75％ auto-callback bone crumbs and 25 ％ hydroxyapatite at 12th week was (55.3 ± 5.6)％,with was higher than other teams.Conclusion The auto-callback bone crumbs and hydroxyapatite biomaterial which were implanted into extraction sockets immediately preserved the socket contour.It enabled newly formed bone in the extraction sockets for future implant site preparation.
