摘要
目的:探讨下颌阻生智牙拔除后,用骨组织工程支架材料充填拔牙窝,修复第二磨牙远中牙槽骨高度的临床效果。方法:13例患者在阻生智牙拔除后,即刻植入组织工程骨微粒(小牛无机松质骨Bio-oss、倍骼生PerioGlasfi)于牙槽窝内,术后定期随访,并从临床和X线影像检查比较术后1、12周时,第二磨牙远中牙龈附着水平和牙槽嵴高度的变化。采用SPSS10.0软件包对数据进行配对样本t检验。结果:所有患者术后未出现并发症,术后12周时,第二磨牙远中牙槽嵴高度显著降低(P<0.05)。结论:下颌阻生智牙拔除术后即刻植入组织工程骨支架材料,有利于保持第二磨牙远中牙槽嵴的高度。
PURPOSE： To investigate the effects of tissue engineered bone scaffold material in the restoration of alveolar socket after extraction of lower impacted third molar.METHODS： Thirteen patients were immediately implanted with Bio-oss or PerioGlas in the alveolar cavity after impacted mandibular third molar extraction.Clinical observation and X-ray were taken 1 to 12 weeks after operation.Paired t test was used for statistical analysis by SPSS10.0 software package.RESULTS： Thirteen patients did not experience postoperative complications.The distal alveolar height of the second molar and the gingival attachment did decrease significantly 1 to 12 weeks after operation（P﹤0.05）.CONCLUSION： Tissue engineered bone scaffold material is helpful in the restoration of alveolar socket after impacted third molar extraction.
