Abstract EN
The purpose of this study was to evaluate the fracture load of two CAD/CAM ceramic veneer materials (IPS Empress CAD and IPS e-max CAD), with three different preparation designs (window, butt-joint, and incisal overlap).
Thirty maxillary anterior teeth were restored with ceramic laminate veneers and divided into 6 groups as follows: group I-A (laminates made of IPS Empress CAD with window preparation design), group I-B (laminates made of IPS Empress CAD with butt-joint preparation design), group I-C (laminates made of IPS Empress CAD with incisal overlap preparation design), group II-A (laminates made of IPS e-max CAD with window preparation design), group II-B (laminates made of IPS e-max CAD with butt-joint preparation design), group II-C (laminates made of IPS e-max CAD with incisal overlap preparation design).
Fracture load test was performed using the Universal Testing Machine (UTM).
Data were statistically analyzed using One-way analysis of variance ANOVA followed by Tukey’s multiple comparison test.
The results of the fracture load test were recorded in Newton: (I-A: 233.7 N); (I-B: 252.1 N); (I-C: 200.3 N); (II-A: 227.6 N); (II-B: 283.5 N); (II-C: 256.7 N).
Statistical analysis showed that the result of the butt-joint design (II-B) was significantly higher than other subgroups, and regarding the materials used, the IPS e-max CAD was significantly higher than the IPS Empress CAD material in fracture load test.
