Purpose:
The aim of this study was to compare the shear bond strengths of four distinct CAD/CAM restorative materials using conventional resin-based adhesive cement and self-adhesive resin cement.
Materials And Methods:
Specimens (14 mm × 18 mm × 2 mm) were obtained for each restorative material: IPS e.max CAD (Ivoclar Vivadent (LEICHTENSTEIN), GC Cerasmart (GC-Corp. JAPAN), Vita-Enamic (Vita-ZahnFabrik, GERMANY), and Cerec Blocks (Dentsply Sirona, USA) (n = 12). Ceramic surfaces were applided with both conventional resin-based adhesive cement (LF) (GC-LinkFORCE, GC Corp., JAPAN) and self-adhesive resin cements (CO) (G-Cem One, GC Corp., JAPAN). The shear bond strength test of 96 specimens were calculated and other 96 specimens were measured this test following thermal cycles (10000 thermal cycles at 5-55 oC (SD Mechatronik THERMOCYCLR, Gmbh). Shear bond strength results were statistically analyzed by independent samples t test, one-way ANOVA, two-way ANOVA, four-way ANOVA and for one and all test Post Hoc Tukey HSD test.
Results:
After thermal cycles, a significant difference was observed between the shear bond strength of LF and CO cements to all ceramics except IPS e.max CAD ceramic (p < 0.05). After thermal cycling, LF cement had the strongest shear bond strength values with GC Cerasmart and the weakest bond values with Vita Enamic. CO cement had the strongest shear bond values with Cerec Blocks ceramics and the weakest bond values with GC Cerasmart. Cohesive type fractures were the most prevalent and adhesive type fractures were the least frequent both before and after thermal cycle. The type of material had a significant effect on the type of fracture after thermal cycle application (p < 0.05).
Conclusions:
Thermal cycle application caused a decrease in the shear bond strength values of two kind of resin cements to all ceramics. It can be concluded that self-adhesive composite resin cement (G-CemONE) are suitable for leucite-reinforced glass-ceramic and lithium disilicate ceramics, and conventional resin-based adhesive cement (GC-LinkFORCE) is suitable for resin nanoceramic material and polymer-infiltrated glass-ceramic material types.

Strength of Cement
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

Types of Cement I
Type I (Ordinary Portland Cement) is widely used for general construction where special properties are not required. It has moderate sulfate resistance and heat of hydration.
Type II (Modified Cement) offers moderate resistance to sulfate attack and a lower rate of heat development compared to Type I. It is suitable for structures in...
