文档介绍：拔牙后牙槽嵴保存的初步临床研究
摘要:目的观察拔牙后牙槽窝即刻植入Bio-Oss Collagen 对于早期牙槽嵴形态的影响。方法选取8例需要对称减数下颌第一恒前磨牙(共16个牙位)的正畸病例,微创拔除后,两侧采取不同处理方式将其分为两组。实验组8个牙位,拔牙窝即刻植入Bio-Oss Collagen,“8”字缝合拔牙窝两侧软组织;对照组8个牙位,拔牙窝自然愈合。拔牙后10 d观察拔牙窝愈合情况,12 周复诊取模型,采用牙槽嵴地图法测量拔牙位点牙槽嵴水平宽度,与拔牙前比较。结果所有病例拔牙窝均正常愈合,拔牙后12周,在测量位点,两组病例牙槽嵴水平宽度均较前减少,实验组差值小于对照组,两者之间的差异有统计学意义(P中国论文网/1/view-

Abstract:Objective To observe the effect of Bio-Oss Collagen immediately after tooth extraction on the morphology of early alveolar 8 orthodontic cases with symmetrical normotensive mandibular first permanent premolars(total 16 teeth)were minimally invasive surgery,they were divided into two groups according to different the experimental group of 8 teeth,the tooth socket was immediately implanted with Bio-Oss Collagen,and the “8” suture was used to suture the soft tissues on both sides of the tooth the control group,8 teeth were 10 d after tooth extraction, the healing condition of the extraction socket was the 12-week follow-up,the model was taken and the alveolar crest width of the extraction site was measured by alveolar ridge mapping Tooth extraction in all cases were normal healing,12 weeks after tooth extraction,in the
