Abstract

EFFECT OF JOINT SURFACE CONTOURS AND CHEMICAL SURFACE TREATMENT ON THE TRANSVERSE BOND STRENGTH OF REPAIRED DENTURE BASE RESIN: AN IN VITRO STUDY

Ulfat Majeed*, Beenish Khan, Darakshan Nazir and Abdul Qayoom Beigh

ABSTRACT

Denture fracture is the most common problem and despite various improvements, the repaired denture often experiences refracture at the repaired site due to poor transverse strength. Purpose: The study aims to compare the transverse strength of self cure repair resin using different joint surface contours and chemical surface treatments. Material and Method: 60 heat cure resin samples of dimension 65 x 10 x 2.5 mm were cut into 2 equal parts with 45 degree bevel and butt joint and then placed in mould with 3 mm gap in middle for adhering with repair material after surface treatment with isopropanol and ethyl acetate following which they were tested for transverse strength on Universal testing machine. Result: The highest bond strength was obtained with autopolymersing resin using bevel joint contour with ethylacetate surface treatment. Conclusion: The autopolymerizing resin exhibited significantly higher repair strength with bevel joint contour. The transverse strength of the repaired specimens was increased significantly after chemical treatments.

Keywords: Dental prosthesis repair, isopropanol, ethyl acetate, transverse strength, joint contours.
