自瑞典Brnemark教授提出了骨结合的理论以来,“骨结合式钛种植体”已日渐成为一种常用的修复牙齿和牙列缺失的治疗方法,经十年以上的多中心跟踪研究显示,其成功率大于90%。经典的牙种植修复程序,要求患者在拔牙后3个月以上接受牙种植体植入术,植入后还要再等3～6个月行二期手术,整个治疗过程周期较长,部分患者不能接受。另外,患者拔牙后牙槽嵴存在一个进行性骨吸收过程, Since the introduction of the theory of osseointegration by Professor Brönemark in Sweden, “bone-bonded titanium implants” have increasingly become a commonly used method for the treatment of tooth and dentition defects. After more than a decade of multicenter follow-up studies Show that its success rate is greater than 90%. Classic dental implants repair procedures require patients to receive dental implants more than 3 months after tooth extraction, after implantation, but also wait for 3 to 6 months for second-stage surgery, the entire treatment cycle longer, some patients unacceptable. In addition, there is a progressive process of bone resorption in the alveolar ridge after tooth extraction,
