采用放射学方法研究了三种不同设计的骨内牙种植体植入犬下颌骨后的骨重建，并在动物处死后进行了组织学检查。 研究的三种设计为（a）螺纹（c. p.钛）、（B）完全多孔涂层（钛合金）和（c）部分多孔涂层（钛合金）。 种植体保持功能32周（完全多孔涂层）或73 - 77周（部分多孔涂层和螺纹）。 研究表明，螺纹和部分多孔涂层种植体都发生了一些牙槽嵴骨丢失，而在没有菌斑相关感染的情况下，完全多孔涂层种植体没有观察到显著的骨丢失。 这表明，这些观察到的差异是由于不同的应力状态，在骨周围的三种设计的植入物设计对骨重建的重要性。
Bone remodeling around three different endossesous dental implant designs placed in dog mandibles was studied using radiography during lengthy periods of function and by histology after animal sacrifice. The three designs investigated were (a) threaded (c.p. titanium), (b) fully porous-coated (titanium alloy), and (c) partially porous-coated (titanium alloy). The implants were kept in function for either 32 weeks (fully porous-coated) or 73 to 77 weeks (partially porous-coated and threaded). The studies indicated that some crestal bone loss occurred for both the threaded and partially porous-coated implants while no significant bone loss was seen with fully porous-coated implants in the absence of plaque-associated infection. It is suggested that these observed differences are a result of the different stress states that develop in bone surrounding the three designs underlying the importance of implant design on bone remodeling.
