摘　　要：目的:观察脱钙人牙基质材料在埋伏牙拔除后促进骨组织愈合的临床效果。方法:共40例埋伏牙拔除患者,随机平均分为A、B组:A组拔牙创直接缝合,为空白对照;B组拔牙窝内即刻植入脱钙人牙基质材料。所有患者均在术前摄全口曲面断层片,术后1周、1个月行局部数字牙片检查;结合临床检查进行比较,观察骨腔愈合及骨重建情况。结果:2组患者创口均Ⅰ期愈合。术后1月X线片检查,A组拔牙窝骨密度仍低于周围正常骨,B组拔牙创骨密度已与正常骨接近。结论:采用脱钙人牙基质材料填入拔牙窝内的方法,骨诱导作用明显,能加速骨组织的修复重建,缩短了拔牙创愈合时间。Objective： To observe the clinical effects of material from decalcified human dentinal metric（DHDM） in promoting bone tissue healing after the extraction of impacted teeth.Methods： 40 patients with impacted teeth were randomly divided into two groups： control group A（20 cases） and experimental group B（20 cases）.After extractions,the wound sockets in group B was filled with DHDM immediately.Those extraction wounds in group A were treated conventionally.Pretreatment panoramic radiographs and periapical radiographs were examined at one-week and one month after surgery.Assessment was made according to the radiographs and clinical examinations.Result： All patients healed by first intention.A month after extraction,the bone density of extraction wound in group A was still a little lower than the normal surrounding bone,but it was similar to normal bone in group B.Conclusion： Filled with material of decalcified human dentinal metric,the reconstruction of bone is accelerated,which shorten the time of wound healing.
