Abstract:
Temporomandibular disorders are a group of symptoms related to the impaired function of the temporomandibular joints and associated muscles. Occlusal splint therapy is a common treatment in the aforementioned syndrome. One of the methods of manufacturing occlusal splints is to place a polymer on thermoplastic foil. The aim of this study was to evaluate the shear bond strength of light‐ and self‐cured resins bonded to thermoplastic foil dependent on artificial aging. Materials and Methods Thirty cylinders composed of light‐cured resin and 30 cylinders made of self‐cured resin were attached to 60 rectangular thermoplastic plates. All specimens were divided into six groups. A control study was conducted for groups 1 and 2. The other preparation groups were subjected to thermocycling by setting appropriately 1000 cycles for groups 3 and 4 and 3000 cycles for groups 5 and 6 in distilled water. Bond strength was measured in a universal testing machine. The results were subjected to statistical analysis using the Mann‐Whitney U test ( p ≤ 0.05). Results The statistics revealed that the values of the shear bond strength for specimens composed of self‐cured resin after 1000 and 3000 thermocycles were significantly higher than on those made of light‐cured resin ( p = 0.003 and p = 0.002). Conclusion The shear bond strength between the self‐cured resin and the thermoplastic foil was higher and more resistant to aging than the shear bond strength between the light‐cured resin and the thermoplastic foil.
