Bottom Line: Specimens were repaired with auto polymerizing acrylic resin using sprinkle on technique.A two-way analysis of variance revealed that there was statistically significant difference in mean strengths of the three groups.Surface chemical treatment with ethyl acetate improved the transverse strength of the repaired heat cure denture base when compared with mechanical roughening with bur and group without surface treatment.

ABSTRACT

Background: Denture repair involves joining two parts of a fractured denture with a denture repair material. Hence, a substantial repairing system for denture base fracture should be there to elude frequent fracture.

Materials and methods: Surface treatment of conventional heat cure denture base resin with different surface treatments (chemical ethyl acetate, and mechanical roughening with bur), with control group formed without surface treatment. Specimens were repaired with auto polymerizing acrylic resin using sprinkle on technique. The testing of the transverse strength of the repaired specimens was evaluated with three-point bending test on universal testing machine.

Results: The study revealed that surface chemical treatment with ethyl acetate improved the transverse strength of repaired heat cure denture base when compared with mechanical and control group. A two-way analysis of variance revealed that there was statistically significant difference in mean strengths of the three groups.

Conclusion: Surface chemical treatment with ethyl acetate improved the transverse strength of the repaired heat cure denture base when compared with mechanical roughening with bur and group without surface treatment.

Figure 1: Specimens were divided with the help of marker pen vertically into two equal parts of 32 mm each.

Mentions: Acrylic resin specimen measuring 66 mm × 12 mm × 2.5 mm were fabricated from wax specimen of the same measurement by the process of acrylization. The prepared intact specimens were divided with the help of marker pen vertically into two equal parts, i.e. 32 mm each. 1 mm was marked on the right and left from the center line on the top, and 3 mm was marked on the right and left from the center line at the bottom respectively (Figure 1). The prepared intact specimens were then vertically cut in accordance with the marking on the specimen.
