Abstract

Objectives: The use of zirconia as a framework for prosthetic restorations is increasing due to its favorable mechanical properties. Zirconia also has remarkable aesthetic properties when used as a framework and covered with a layer of cosmetic ceramic. The aim of this study was to compare the fracture toughness of three types of aesthetic Ceramics, namely VITA VM® 9, ceraMotion® Zr, and IPS e. max® Ceram. Materials and Methods: Three groups of aesthetic Ceramics (n=10) were subjected to three-point bending tests. The force leading to fracture was recorded for each sample to measure the impact of the ceramic type on the solidity of the framework. The type of fracture has not been studied in this work. One-way analysis of variance (ANOVA) was used to statistically analyze the results. Results: The statistical analysis showed significantly different fracture toughness values among the three groups. IPS e. max® showed the lowest fracture toughness (25. 42 MPa) compared to VITA VM® 9 and ceraMotion® Zr (respectively 40. 39 MPa; P<0. 001, and 48. 78 MPa; P<0. 005). Conclusions: Within the limitations of the present study, it can be concluded that aesthetic Ceramics play an important role in the fracture toughness of all-ceramic restorations.
