A comparative study of the bone forming ability of surface-treated porous titanium materials

本研究旨在探讨表面处理对多孔钛种植体长期成骨能力的影响。应用三种类型的表面处理：（a）羟基磷灰石涂层（HA），（B）碱、热水和热处理（AW），和（c）碱、稀HCl、热水和热处理（HCl）。然后，我们在6、12、26、52和104周检查了日本白色家兔股骨髁内植入材料内的骨形成量。结果表明，AW和HCl中的骨长入分别在52周和12周后显著高于HA。

We investigated the effect of the surface treatment on the bone forming abilities of porous titanium implant in the long term. Three types of surface treatments were applied :(a) hydroxyapatite coating(HA),(b) alkali, hot water, and heat treatment(AW), and(c) alkali, dilute HCl, hot water, and heat treatment(HCl). We then examined the amount of bone formation within the materials implanted in the femoral condyles of Japanese white rabbits at 6, 12, 26, 52, and 104 weeks. The results showed that the bone ingrowth in AW and HCl was significantly higher than in HA after 52 and after 12 weeks, respectively.
