| Research Abstract |
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.
