Abstract
AIM or PURPOSE
This study aimed to evaluate the bonding performances of different veneering materials to fiber-reinforced high-performance polymers (FRC), as there is no investigation on the possibility of using nanohybrid ceramics to replace composite resins in terms of bond strength.
MATERIALS and METHOD:15 Trinia specimens with dimensions of 10mm diameter and 1mm thickness were divided into three groups based on veneering materials (n=5 each)
CAD/CAM millable nanohybrid ceramic resin-CeraSmart (CS), light-curing microhybrid composite Ceramage (CE), and 3D printable nanohybrid composite resin-VarseoSmile (VS). The specimens were luted to frameworks and underwent mechanical fatigue testing along with thermal cycling (240.000 chewing cycles with a vertical stress of 100 N, frequency of 1.2 Hz, sliding movement of 0.7 mm; thermocycled in distilled water between 5°C and 55°C, 30 s each. Shear bond strength (SBS) at the FRC–veneer resin interface was measured post-fatigue test, and statistical analysis was conducted using IBM SPSS version 26 and the Kolmogorov-Smirnov test for normal distribution confirmation. Two-way ANOVA with post-hoc multiple comparisons using Tukey HSD test was used, with significance set at p≤0.05.
RESULTS
The SBS values of Ceramage composite resin, Cerasmart milled hybrid ceramic, and Varseosmile 3D-printed hybrid resin were found as 10.96 ± 2.98 Mpa, 4.45 ± 5.01 Mpa, and 4.92 ± 2.69 Mpa, respectively. While Ceramage resin had a significantly higher SBS than the others, no significant difference was observed between the CeraSmart and VarseoSmile materials.
CONCLUSION(S)
Constructing a dental prosthesis framework using a fiber-reinforced polymer can benefit from the use of composite resin as a veneering material.
