摘要
背景:理想的骨引导材料可最大程度地恢复拔牙窝处软硬组织形态,利于牙体种植的成功。目的:比较不同骨代材料恢复和重建拔牙窝处软硬组织的能力。方法:纳入2010-01/2011-01于新疆医科大学第五附属医院口腔颌面外科拔除前牙或前磨牙的60例患者,随机分为3组,Bio-Oss组和羟基磷灰石组于拔牙后分别应用Bio-Oss、羟基磷灰石对拔牙窝进行填充,空白对照组拔牙后不进行任何干预。结果与结论:分别于拔牙前及拔牙后6个月测量各组邻面牙槽嵴高度、牙间乳头高度及唇舌向宽度,经比较发现,Bio-Oss组各项指标变化最小,羟基磷灰石组次之,空白对照组变化最大。说明Bio-Oss作为拔牙后牙槽窝的骨代材料能够更好地维持甚至增加牙槽嵴的骨量,促进软组织外形的恢复。
BACKGROUND： The ideal bone materials for guiding bone tissue regeneration can maximally recover hard and soft tissue morphology of tooth extraction fossa, which are conducive to the success of dental grown. OBJECTIVE： To compare the effects of different guided bone tissue materials on extraction socket in early reconstruction. METHODS： A total of 60 patients required the extraction of the teeth, and they were randomly divided into three groups with 20 teeth in each. The teeth were extracted and the different guided bone tissue materials were implanted. Bio-Oss and hydroxyapatite were implanted into the Bio-Oss and hydroxyapatite groups after tooth extraction, and no treatment was done in the control group. RESULTS AND CONCLUSION： The heights of the proximal alveolar bone and the interdental papilla as well as the width of lip to lingua were changed little in the Bio-Oss group, more in the hydroxyapatite group, and most in the control group. It can prove that Bio-oss is the best guided bone tissue material in conserving the alveolar ridge after tooth extraction.
