Effect of Different Surface Treatments on The Tensile Bond Strength Between Acrylic Resin Teeth and Denture Base Material

Ihab Nafea Yaseen


Aims of study: A study was carried out to assess the tensile bond strength between acrylic denture base and denture teeth af- ter manipulation with different surface treatments.

Methods: Thirty central incisors from acrylic denture teeth were cut at the neck (ridge lap surface). Such teeth were then allocated into three groups of different surface treatments: teeth in the first group received no further treatment; teeth in the second group were surface treated with a groove placed and reinforced with a metal wire; teeth in the third group were reinforced with a glass fiber. Each group was processed by water – bath. Results: The results showed that all treated groups improved the tensile bond strength was in a significant, level at (P<0.01), while the third group glass fiber was the highest mean values.

Conclusions: The metal wire enhanced significantly the tensile bond strength. The addition of glass fiber can significantly enhance the tensile bond strength between acrylic denture base and denture teeth.
