种植牙的研究应包括材料特性及其在机体中支持组织的反应。本研究方法是用一种铝瓷制成,带有小孔和大孔的牙根状园柱形种植体植入动物体内。孔的大小则依据既往资料证明设计,大孔(150μ)可容许骨质长入,而小孔(20—40μ)只是容许纤维长入。将21个大孔和22个小孔的氧化铝种植体植在22只杂种大狗口内,种植体的冠部暴露。虽然将种植体固定8周,应用抗菌素和保持卫生,每月作一次临床和X线检查,仍发现种植体不稳定(易变化),表现有进行性骨吸收、炎症和松动,最终在六个月时全部
Dental implant research should include material properties and their response to supporting tissues in the body. This research method is made of an aluminum porcelain rooted cylindrical implant with holes and large holes implanted in animals. The size of the holes is based on proven data. Large holes (150μ) allow for bone ingrowth, while small holes (20-40μ) allow for fiber infiltration. 21 large holes and 22 holes of alumina implant planted in 22 hybrid big dog mouth, the crown of the implant exposed. Although the implant was fixed for 8 weeks, applied antibiotics and maintained hygienic, once a month for clinical and X-ray examination, the implant was found to be unstable (changeable) with progressive bone resorption, inflammation and loosening, eventually resulting in six All month
