【摘要】 目的评估异种脱细胞真皮基质在引导骨组织再生修复牙槽骨缺损中的作用。方法选择因牙周病、牙槽外伤等导致牙槽骨缺损严重、拔牙术后不能满意修复的患者16例,拔牙同期在拔牙窝植入Bio-oss骨粉并覆盖异种脱细胞真皮基质,术后2周拆线,3个月、9个月复诊。结果术后临床检查、X线检查,16例患者植骨区新骨形成良好,明显改善牙槽骨高度与丰满度。结论临床上异种脱细胞真皮基质的应用能有效地改善修复前的骨条件。更多还原

【Abstract】 Objective To investigate the effect of xenogenic acellular dermal matrix(ADM) on guided bone regeneration in alveolar defect. Methods 16 patients who had severe alveolar bone defect,could not be satisfied with the repair after tooth extraction operation resulted from periodontal disease,alveolar trauma were selected. Bone defect after teeth extraction was very serious and the residual height and width of the alveolar bone were very limited in all these cases. Bio-oss bone powder was delivered into the sockets immediately after tooth extraction and covered with xenogenic acellular dermal matrix. Suture was removed after 2 weeks,and the alveolar bone was regularly examined in the 3rd and the 9th month. Results New bone was found to form well in both physical examination and X-ray examination in all the 16 cases in the 9th month. The height and width of the alveolar bone significantly increased,providing a good bone condition for later FPD prosthetic treatment. Prosthetic treatments were performed in the 9th month and good outcomes were achieved. Conclusion The clinical application of xenogenic acellular dermal matrix can improve the bone condition before restoration.更多还原
