为建立与临床即刻种植相符的动物模型，采用去骨法扩大犬下颌前磨牙新鲜拔牙创和种植直径２ｍｍ自攻螺纹式纯钛种植体，对以往即刻种植动物实验模型加以改进，使种植体植入后其近中留有３ｍｍ×３ｍｍ×５ｍｍ的骨缺损区，设计为异体脱钙冻干骨粒（ＤＦＤＢＡ）植入组和对照组，于术后２周、４周、８周、１２周取材观察骨缺损愈合情况。结果，ＤＦＤＢＡ植入组１２周骨缺损为新骨替代，对照组骨缺损仅修复３／５。该模型制作简便、制模时间短、接近临床，是一种较好的用于即刻种植研究的动物模型
In order to establish an animal model that is in line with the immediate clinical planting, a new 2-mm diameter self-tapping titanium implant was expanded by deboning to extend the premolar teeth of canine mandible, and the experimental model of the immediate implanting animals was improved to implant the implant A 3 mm × 3 mm × 5 mm bone defect area was left in the proximal part of the bone defect. The DFDBA implanted group and the control group were designed and were harvested at 2 weeks, 4 weeks, 8 weeks and 12 weeks after operation Observation of bone defect healing. As a result, 12-week bone defect in the DFDBA-treated group was replaced by new bone, while in the control group, the defect was only 3/5. The model is easy to make, the modeling time is short, close to the clinic, which is a good animal model for immediate planting research
