Abstract
The object of this study was to find out the effect of reinforcing wires (Co-Cr wrought clasp wire) in denture repair with the newly developed self-cured type 4-META adhesive resin (META-FAST). Evaluation was performed by the bending test on rectangle shape (70×10×2mm) resin specimens with repair portion in the middle.
Following Results were obtained:
1) Maximum bending strength of the fractured resin specimens repaired with resin alone showed 70% of those original values, but the amount of deflection under 2 kg load did not change.
2) In specimens repaired with META-FAST and Co-Cr wire, the increase of maximum bending strength, the load at the propotional limit and the decrease of deflection under 2kg load were observed.
3) The longer reinforcing wire became, the greater reinforcing effect were obtained.
4) Necessary length of reinforcing wire should be determined by the relation between load and stress distribution pattern in the denture-base for each individual case.
