口腔内自体骨移植诱导牙槽骨再生的临床研究

A Clinical Study on Alveolar Osteanagenesis Induced by Intraoral Autografting

对 30例牙周病患者采取了口腔内自体骨移植诱导牙槽骨再生。临床观察 10 8处手术区、 488颗牙手术前后的症状、牙周袋深度、附着水平以及 X线摄片结果 ,将测量数据进行统计学分析。认为该方法可较好地解决牙周病骨缺损口腔内自体骨移植的骨源不足问题 ,自体骨既有成骨和诱导成骨的作用 ,又能作为支架以使新骨爬行生长 ,且无免疫排斥之虑。

cases of periodontal patients with alveolar bone defects were treated by intraoral bone autografting to induce alveolar bone regeneration.The symptoms,the depths of periodontal pockets,attachment levels and radiographs of alveolar bone of 108 operation regions involving 488 teeth were studied before and after operation,and the parameters were analyzed statistically.The results indicate that the method can satisfactorily solve the problem of insufficient donation of bone source in restoration of alveolar defects through intraoral bone autografting. Furthermore,because it is autografted,the bone restoring the alveolar defect is not only capable of inducing and enhancing bone regeneration and serving as framework for the growth of new bone,but also free from the problem of immuno incompatibility.
