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<)。结论 Bio-Oss Collagen的植入减轻了拔牙后牙槽嵴的萎缩,较好地保存了拔牙位点的水平骨量。

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 se
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 week
