Abstract

Objective: The purpose of this study was to investigate the effects of the different surface treatments on fracture strength of the zirconia-based ceramic restorations. Methods: Each of 120 dental implant abutments and analogs were used in the present study. Zirconia core materials were manufactured on dental implants by using CAD/CAM device and they were randomly divided into 6 groups (n=20) according to surface pretreatments; control group (Group C), airborne-particle abrasion (Group AA), silica-coating (Group SC), Nd:YAG laser (Group N), bur-cut from cervical region (Group BC), and bur-cut on the functional tubercule (Group BT). Cementation was succeeded with two different types of cements including a dual-cure resin-cement and a glass ionomer cement. The obtained data were evaluated statistically using one-way ANOVA and Tukey tests (p=0.05). Results: No statistically significant difference was found between the groups (p>0.05). Similarly, no statistically significant difference was found between the resin cement and glass ionomer groups with respect to fracture strength values (p>0.05). Conclusion: Within the limitations of the present study, surface treatments and cement have no effect on the flexural strength of zirconia ceramic crowns.
