In order to investigate the castability of titanium, Kennedy Class ¥°, division 2
removable partial denture frameworks were designed. According to the manufacturer's
instruction, 10 casting bodies each were obtained with pure titanium and cobalt-chrome
alloy. The results were as follows ;
1. Castability of titanium was comparable with that of cobalt-chrome alloy in terms of
fitness and surface detail reproducibility.
2. There was no radiographically detectable porosity in each casting body of titanium
and cobalt-chrome alloy.
3. The number of infernal porosities and narrow, long defects were almost same
between titanium and cobalt-chrome alloy.
4. Vickers hardness number of cobalt chrome alloy was 439.4¡¾16.1 and that of
titanium was 200.1¡¾23.3.
5. Biocompatibility and low density of cartable titanium would provide denture wearers
with multiple benefits.
