近年来即刻种植已经逐步成为临床种植医生的有效选择之一,但是自然牙拔除后的喇叭状拔牙创,使种植体上部与拔牙窝间存在间隙,成为影响即刻种植术成功的重要因素。即刻种植的骨缺损动物模型,是在动物体内建立种植体周围骨缺损,模拟即刻种植体与拔牙创间隙,这一方法可用于研究种植体周围缺损、种植体表面处理技术、引导性骨再生技术及植骨材料等对即刻种植体骨结合性能的影响。本文就即刻种植体周围骨缺损相关的动物实验模型作一综述。 In recent years, immediate planting has gradually become one of the effective choices for clinical implant doctors. However, the horn-shaped tooth extraction after natural tooth extraction makes the gap between the upper part of the implant and the extraction socket become an important factor that affects the success of immediate planting. Immediate implanting animal model of bone defect is to establish bone defect around implant in animal and simulate the gap between immediate implant and tooth extraction. This method can be used to study the peri-implant defect, implant surface treatment, guided bone regeneration And bone graft material on the immediate implant bone binding properties. This article reviews the experimental animal models associated with immediate bone defects in implants.
