目的：本研究的目的是评估的牙槽嵴保存技术提取后使用胶原蛋白海绵和异种移植的疗效。研究设计：二十例患者分为实验组和对照组各10例，其中包含约。对照组计划的3个单位的桥梁不进行植入无特殊治疗拔牙，修复治疗3个月后进行。在实验组，采用胶原海绵和异种骨移植，牙槽嵴保存是同时进行拔牙；植入物被放置在3个月后。临床和组织学评估，并进行统计学分析。结果：对牙槽骨3毫米低于对照组的牙槽嵴宽度的吸收率为20.74%，与实验组平均为14.26%，观察到约相差6%，差异有显著性。在骨移植材料的新骨形成了附近，与炎症的研究并没有观察到。结论：结果表明，应用胶原蛋白海绵和异种移植齿槽嵴保存，防止牙槽脊水平吸收，与胶原海绵块上的软组织浸润到较低的地区，因此它具有骨填充增强优势。
