| Abstract | ||
| Denture fracture is one of the most common problems encountered by the patients and prosthodontics. An attempt have been made to improve the mechanical properties of the repaired heat cure acrylic resin by chemical surface treatment. The aim of this study was to evaluate and compare the transverse strength of repaired conventional and hi-impact heat cure denture base resins with and without surface chemical treatment. .Four organic solvent which are available in the Iraqi market acetone, isopropanol, toluidine and ethyl acetate were used. A total of 100 specimens of 64±0.3×10±0.03×2.5±0.03mm dimensions were prepared, fifty specimens of each heat cure acrylic resin type (conventional and high impact), each fifty specimens were farther divided into five subgroups of 10 specimens as follow, control group (without surface treatment), surface treatment with organic solvent. The result of the study revealed that surface chemical treatment with acetone, ethyl acetate, isopropanol and toluidine improved the transverse strength of repaired heat cure denture base when compared with control group. Tow-way ANOVA indicated that surface treatment had a significant influence on the transverse strength. It can be concluded surface chemical treatment with acetone, ethyl acetate, isopropanol and toluidine improved the transverse strength of repaired heat cure acrylic. | ||
