“…In our study, the highest fracture strength of endocrowns were observed in TZI group (533.61 N for S, 610.54 N for L) which has the highest elasticity moduli and flexural strength, and the lowest values were found in VM2 (47.29 N for S, 71.38 N for L) groups, in accordance with the literatures by Leung et al 40) and Albero et al 41) . The reason for lower fracture strength values obtained in our study for all groups could be attributed to the differences in crown shape (incisor instead of molar) and the force axis (45 degrees angle instead of 90 degrees angle) used in this study.…”

“…The study which compared the mechanical properties of feldspathic ceramic (Vita Mark II), lithium disilicate reinforced glass ceramic (IPS e.max CAD) and polymer infiltrated ceramic (Vita Enamic) by three-point bending test, reported that lower flexural strength values were found for feldspathic ceramic (106.67±18.50 MPa) with respect to lithium disilicate reinforced glass ceramic (341.88±40.25 MPa) and polymer infiltrated ceramic (145.95±12.65 MPa) 40) . Similarly, Albero et al 41) reported that feldspathic ceramic (Vita Mark II) provided lower fracture strength values with respect to lithium disilicate reinforced glass ceramic (IPS e.max CAD), polymer infiltrated ceramic (Vita Enamic) and resin-ceramic (LAVA Ultimate). There are some studies which examine the performance of ceramic materials for endocrown restorations in terms of fracture strength.…”

The objectives of this study were to compare the fracture strength of endocrown restorations fabricated with different preparation depth and various CAD/CAM ceramics, and to assess the fracture types. Endodontically treated 100 extracted human permanent maxillary centrals were divided into two preparation depth groups as short (S: 3-mm-deep) and long (L: 6-mm-deep), then five ceramic subgroups, namely: feldspathic-ceramic (Vita Mark II-VM2), lithium-disilicate glass-ceramic (IPS e.max CAD-E.max), resin-ceramic (LAVA Ultimate-LU), polymer infiltrated ceramic (Vita Enamic-VE) and monoblock zirconia (inCoris TZI-TZI) (n=10/subgroup). The endocrowns were fabricated by CAD/CAM and were cemented with resin cement (RelyX U200). The teeth were thermally cycled (5,000cycles) and fracture tests were performed at 45º angle to the teeth. The data were statistically analyzed (Kruskal-Wallis, Mann Whitney U), failure modes were evaluated with stereomicroscopy. Zirconia group provided the statistically highest fracture strength, but also exhibited non-repairable failures. Preparation depth has an effect on the fracture strength only for feldspathic ceramic.

“…58,63 Typical ceramic materials have a higher elastic modulus values than PICN 64 . The Vickers hardness of human enamel (3.43 ± 0.16 GPa) and PICN (3.31 ± 0.11 GPa) are similar, 54,65,66,67 and both are higher than the hardness reported for resin composites (0.73 GPa to 1.60 GPa), 68,69 and lower than the hardness of zirconia (13.94 GPa) 70 and lithium disilicate glass ceramics (10.0 GPa to 11.31 GPa). 71 The flexural strength of Enamic (130 MPa) 56 is lower than that of a reference lithium disilicate glassceramic material, IPS e.max (342 MPa).…”

Dental ceramics: a review of new materials and processing methods

et al. 2017

View full text Add to dashboard Cite

The evolution of computerized systems for the production of dental restorations associated to the development of novel microstructures for ceramic materials has caused an important change in the clinical workflow for dentists and technicians, as well as in the treatment options offered to patients. New microstructures have also been developed by the industry in order to offer ceramic and composite materials with optimized properties, i.e., good mechanical properties, appropriate wear behavior and acceptable aesthetic characteristics. The objective of this literature review is to discuss the main advantages and disadvantages of the new ceramic systems and processing methods. The manuscript is divided in five parts: I) monolithic zirconia restorations; II) multilayered dental prostheses; III) new glass-ceramics; IV) polymer infiltrated ceramics; and V) novel processing technologies. Dental ceramics and processing technologies have evolved significantly in the past ten years, with most of the evolution being related to new microstructures and CAD-CAM methods. In addition, a trend towards the use of monolithic restorations has changed the way clinicians produce all-ceramic dental prostheses, since the more aesthetic multilayered restorations unfortunately are more prone to chipping or delamination. Composite materials processed via CAD-CAM have become an interesting option, as they have intermediate properties between ceramics and polymers and are more easily milled and polished.

“…3,5,6 Within these materials, Lava Ultimate (3M ESPE, St. Paul, MN, USA) is a nanoceramic resin that is composed of nanoceramic particles embedded in a highly cross-linked resin matrix, 3,4 and Vita Enamic (VITA Zahnfabrik, Bäd Sackingen, Germany) is a polymer-infiltrated ceramic network that consists of a feldspar ceramic network infiltrated with a dimetacrylate polymer network. 7,8 An additional material that became available for CAD/CAM technology is Vita Suprinity (VITA Zahnfabrik, Bäd Sackingen, Germany). This material consists of a zirconiareinforced lithium silicate ceramic that supports a wide range of applications, and after crystallization, exhibits higher mechanical properties.…”

Microtensile bond strength of CAD/CAM materials to dentin under different adhesive strategies

The present study aimed to evaluate the microtensile bond strength (µTBS) of novel computer-aided design/computer-aided manufacturing (CAD/CAM) restorative materials to dentin using different adhesive strategies. Thirty-two crowns were milled using CAD/CAM materials (Vita Mark II as control, Vita Suprinity, Vita Enamic and Lava Ultimate) and luted to dentin using different resin cements (RelyX ARC, RelyX Unicem 2 and RelyX Ultimate). The specimens were stored in 100% relative humidity at 37°C for 24 h and sectioned. The samples (n = 16) with cross-sectional areas of approximately 0.90 mm², were submitted to a µTBS test in a universal testing machine with a crosshead speed of 0.5 mm/min. The samples were analyzed with SEM to determinate the failure mode. According to 2-way ANOVA and Tukey's test (α=0.05), the interaction effect (material x luting strategy) was significant (p=0.001). Regardless of the luting strategy, a higher µTBS was obtained with Lava Ultimate and Vita Enamic, which were significantly different from Vita Mark II and Vita Suprinity (p<0.05). For Vita Mark II, Vita Suprinity, Vita Enamic, and Lava Ultimate, the µTBS obtained with RelyX Unicem 2 was not significantly different from that obtained with RelyX ARC or RelyX Ultimate. All groups obtained at least three types of failure. The adhesive strategy with self-adhesive resin cement was comparable to conventional resin cement with total-etch or self-etch adhesive techniques in the bond of novel CAD/CAM materials to dentin.
