“…60,61,63 The elastic modulus of these materials is in the range of 30 GPa, which is half of that reported for conventional veneering ceramics but closer to what is usually reported for dentin (15)(16)(17)(18)(19)(20). 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).…”

“…The selection of resin, the application of high pressure during the curing phase, and the silanization process enhanced bonding and helped overcoming the aesthetic problems by increasing the translucency of the material. 64 However, Enamic has been shown to be less translucent than IPS e.max or Lava Ultimate (3M ESPE, St Paul, USA). 74 Previous works have also shown that the surface of PICN is not as glossy as those obtained for IPS e.max or Lava Ultimate.…”

“…A chewing simulation of five years demonstrated that none of the Enamic crowns failed, while six IPS e.max CAD had minor cracking and twelve Vita Mark II restorations revealed significant crack failures. 64 In a cyclic fatigue experiment of 500,000 cycles, Enamic performed as well as a lithium disilicate glass-ceramic. 58,76 Based on the reduced elastic modulus of Enamic, this material is especially indicated for prosthetic treatments on stiff implants.…”

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.

“…14 In previous studies, the moduli of elasticity of Vita Enamic and Lava Ultimate were 30.1 GPa 15 and 12.8 GPa, 4 respectively, which are similar to that of dentin (16 -20.3 GPa) 6 and lower than those of Vita Mark II (57.2 GPa) 16 and Vita Suprinity (70.44 GPa). 9 Moreover, Vita Enamic and Lava Ultimate have similar moduli of elasticity to resin cements.…”

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

et al. 2017

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.

“…Compared to ceramic restorative materials, Enamic has reliable millability and edge stability in terms of its ability to be fast milled into thin (< 0.5 mm) restorations with excellent precision. 101 A full contour posterior crown takes just a little over 5 minutes to mill, while eliminating the need for post milling firing. The material is also easy to adjust and polish.…”

SYNOPSIS A survey of the development of dental ceramics has been presented. Such an attempt provides a better understanding of the rationale behind the development and clinical indications of each class of ceramic material. Knowledge of the composition, microstructure, and properties of a material is critical for selecting the right material for specific applications. The key to successful ceramic restorations rests on material selection, manufacturing technique, and restoration design. This also includes the balancing of several factors such as residual stresses, tooth contact conditions, tooth size and shape, elastic modulus of the adhesives and tooth structure, surface state, etc.
