The present study aimed to determine morphological characteristics and bone inductivity of the blasted-substrate interface, for dental titanium implant blasted with hydroxyapatite (HA) /β-tricalciumphosphate (β-TCP) eutectic composites. For this purpose, the bone contact ratio at the bone -implant interface and the mechanical strength by implant removal torque were determined to compare the effects of different surface treatments on the promotion of bone formation around dental implants. The study examined the machined surface, the acid -etched surface, the blasted - substrate surface at five minutes cleaning, and the blasted-substrate surface without cleaning. The main results were as follows. 1. The observation of the blasted-substrate surface showed that the HA/β-TCP eutectic composites did not remain on the titanium surface after the cleaning procedure of the implant material. 2. The results clearly showed that the blasted-substrate surface with five minutes cleaning was the shortest period needed for osseointegration among the four different surface treatments.
