Mechanical and optical properties of monolithic CAD-CAM restorative materials

Clinical evaluation of chairside‐fabricated partial crowns composed of zirconia‐reinforced lithium silicate ceramics: 3‐year results of a prospective practice‐based study

“…Several in vitro studies have evaluated the mechanical, physical, and optical properties of this type of dental ceramic since their introduction in 2013 …”

“…Furthermore, a similar fracture toughness of ZLS ceramics was observed compared with lithium disilicate ceramics . An improved translucency and improved polishing characteristics compared with lithium disilicate ceramics could be demonstrated in vitro …”

In Vitro Analysis of the Fracture Resistance of Cad-Cam Cerasmart Molar Crowns with Different Occlusal Thickness

“…The use of monolithic metal-free crowns presented both mechanical and biological advantages: the absence of veneering porcelain eliminates the risk of ceramic chipping and the prosthetic room reduction due to the absence of metal framework and opaque layer allows for tooth tissues preservation. Moreover, metal-free restorations offer a more natural tooth-like appearance, resulting in astounding esthetics and optimal translucency [6,7]. On the basis of minimal intervention dentistry, the preservation of tooth structures is crucial and produced a significant change in preparation designs that have become more and more conservative particularly in posterior regions, taking advantage of adhesive cementation techniques [2,8,9].…”

Interestingly, Dozic et al (2003) was able to demonstrate that a 0.70mm ceramic core has the capability to mask a discoloring background under their layered specimens, which would otherwise display an increased ΔE.…”

“…Previous studies have been conducted on how translucency can affect the optical properties of all-ceramic systems (Akar et al, 2014;Al Ben Ali, Kang, Finkelman, Zandparsa, & Hirayama, 2014;Awad et al, 2015;Barizon et al, 2014;Harada et al, 2016;Heffernan et al, 2002;Johnston, 2014;Sen & Us, 2017;Skyllouriotis, Yamamoto, & Nathanson, 2017;Turgut et al, 2014;Vichi, Carrabba, Paravina, & Ferrari, 2014;Vichi et al, 2011;Wang et al, 2013).…”
