Comparison the tensile strength of heat cure and visible light cure acrylic resin denture base

Abstract EN

Background : visible light cured acrylic resin denture materials are one of the developed polymeric acrylic denture base and are manufactured in the form of sheets and rapes, and also in powder and liquid system, they can be adapted for various dental uses and provides rapid service at low cost.

This study aimed to compare the tensile strength of heat cured acrylic resin and visible light cured acrylic resin.

Materials and Methods : Twenty samples of acrylic denture base materials were prepared, ten samples of heat cured acrylic denture base materials and ten samples of visible light cured acrylic denture base material.

After curing of both groups, the materials were subjected to tensile strength test with the use of Instron universal testing machine.

Results : the results of the present study showed a high significant difference comparing between the two groups ; heat cured acrylic denture base material showed a high significant tensile strength than the visible light cured acrylic denture base material.

Conclusion : heat cured acrylic denture base resin showed superiority in the tensile strength values than the visible light cured acrylic denture base material.
