The purpose of this study was to examine whether the precipitation of calcium
phosphate on titanium implant are affected by surface modification. To improve the bone
conductivity of the Cheil implant(Cheil Pharma & Instrument Inc), samples were divided
into 3 groups. Group 1 was untreated, group 2 was immersed in 5M-NaOH solution at
60% for 24 hours, and group 3 was immersed in 5M-NaOH solution at 60¡É for 24
hours and heat-treated at 600¡É for 1 hour. And then, all specimens were immersed in
the MEM Eagle's medium whose composition was similar to that of extracellular fluid
for 30 days. After immersion, the surfaces were observed with scanning electron
microscope.
The results obtained were summarized as follows;
1. The surface of Branemark implant showed more regular and smooth machined
surface than that of Cheil implant.
2. The precipitation of the calcium phosphate on implant surface was increased by the
immersion in the NaOH solution, and more highly accelerated by heat treatment.
3. The precipitation of the calcium phosphate on titanium implant was lower than that
on the polished titanium surface.
