Abstract
Abstract: Ensuring optimum bond strength during cementation is vital for restoration success, with
the practicality of the process being crucial in clinical practice. This study analyzed the effect of
a single-step self-etching ceramic primer (MEP) and various surface treatments on the microshear
bond strength (µSBS) between resin cement and glass-ceramic or polymer-based ceramic CAD/CAM
materials. Specimens were fabricated from leucite-based glass-ceramic (LEU), lithium disilicate glassceramic (LDC), resin nanoceramic (RNC), and polymer infiltrated ceramic network (PICN) (n = 160).
They were then classified based on the surface treatments (n = 10): control (no treatment); sandblasting
with Al2O3
(AL); etching with hydrofluoric acid (HF); and MEP application. Scanning electron
microscopy was used to evaluate the surface topography. µSBS was measured after cementation
and thermocycling procedures. Failure modes were examined with a stereomicroscope. Statistical
analysis involved two-way analysis of variance and Tukey HSD tests with a significance level of 0.05.
µSBS was significantly influenced by both surface treatment and CAD/CAM material type. The most
enhanced µSBS values for each material, regarding the surface treatment, were: LEU and LDC, HF;
RNC, AL; PICN, AL or HF. MEP significantly increased the µSBS values of CAD/CAM materials
except RNC, yet it did not yield the highest µSBS values for any of them.
