Abstract
|
|
|
The object of this study was to find out the effect of various reinforcing materials including Quarts SplintTM Mesh on
the transverse strength of the denture resin. QC-20 and Lucitone199ⓡ were used as the denture resin, and polyethylene
fiber Ribbondⓡ, light curing quarts fiber Quarts SplintTM Mesh, metal mesh were used as the reinforcing materials. Ten
specimens were fabricated for each group and the size of specimens was 2.0×10.0×65.0 mm. To compare the effect of
resin thickness, additional specimens of 2.5×10.0×65.0 mm, 3.0×10.0×65.0 mm were fabricated. In the control group,
the transverse strength of Lucitone199ⓡ was significantly higher than that of QC-20(p<0.05). Among the specimens of 2.0
mm thickness fabricated with Lucitone199ⓡ and QC-20, they showed high transverse strength in the order of metal mesh,
Quarts SplintTM Mesh, Ribbondⓡ, and control group. In the specimens of 2.0 mm, 2.5 mm thickness, the transverse strength of Quarts SplintTM Mesh were significantly higher than that of QC-20(p<0.05). But in the specimens of 3.0 mm thickness, there was no significant difference.
