Effect of Cigarette Smoking on the Surface Roughness, Color, and Translucency of Zirconia Produced by Additive and Subtractive Manufacturing

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To compare the surface roughness, color stability, and translucency of zirconia produced by additive manufacturing (AM) and subtractive manufacturing (SM) after exposure to cigarette smoking. Materials and Methods A total of 60 disc‐shaped specimens were fabricated from 2 methods: AM (INNI Cera BCM W500/1000) and SM (VITA YZ T).

Translucency Changes of Ceramic Veneers After Aging When Cemented on Substrates With Different Saturation: Effect of Ceramic Translucency and Resin Cement Shade

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of ceramic translucency and resin cement shade on the translucency alteration after aging over different substrates. Methods Sixty specimens were divided into 12 groups (n = 5) composed of lithium disilicate (IPS e.max CAD, Ivoclar Vivadent) in three translucencies (HT, MT, LT).

Hydraulic fast‐setting calcium silicate cement for crown cementation

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated film thickness, diametral tensile strength (DTS), and crown retentive strength of hydraulic fast‐set calcium silicate cement (fast‐set CSC) compared to conventional luting cements. Materials and Methods Fast‐set CSC was compared to zinc phosphate cement and glass ionomer cement.

Does treatment‐induced surface roughness of 3 mol% yttria‐stabilized tetragonal zirconia polycrystals influence the wear of opposing restorative materials? An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to investigate whether different surface treatments applied to 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP), with comparable mean roughness (Ra) values, result in comparable values of additional surface roughness parameters, and to evaluate the influence of zirconia surface topography on vertical ...

Accuracy and clinical passive fit of reverse and standard scan body protocols for complete‐arch implant‐supported digital impressions: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to compare the reverse scan body (RSB) and standard scan body (SCB) protocols for complete‐arch implant‐supported digital impressions with respect to root mean square (RMS), linear deviation, and angular deviation values, as well as clinical passive fit.
