Influence of Different Esthetic Post and Core Materials on Color of Ips Empress 2 Ceramic Crowns
Background and aim: Studies as to the evaluation of clinically relevant color assessment of full ceramic restorations supported by esthetic post and core materials has not been found in the related literature. Thus, this study is conducted to evaluate the color difference of Empress 2 ceramic crowns restored with 4 different esthetic post systems and two different core materials by using colori...
متن کاملClinical performance of IPS-Empress 2 ceramic crowns inserted by general dental practitioners.
AIM The aim of this study was to evaluate the clinical performance of IPS-Empress 2(R) all-ceramic crowns placed by general dental practitioners. METHODS AND MATERIALS Eighty-two IPS-Empress 2 crowns placed in 64 patients (27 females and 37 males) were evaluated. These crowns had been in place for 15.2 to 57.2 months (mean 25.3 months, SD=9.3). Survival analysis was conducted using the Kaplan...
متن کاملMicrostructure of etched "IPS Empress" heat-pressed ceramics observed by SEM.
A valuable characteristic of the "IPS Empress" used for producing all ceramic dental restorations is that it is a prefired ceramic ingot. The ingot is heated, softened and press-injected into the cavity, and ceramic restorations are fabricated by the lost wax casting method. The leucite crystal present in the ingot are scattered and distributed into the glassy phase in a more homogeneous manner...
متن کاملFracture strength of three all-ceramic systems: Top-Ceram compared with IPS-Empress and In-Ceram.
PURPOSE The purpose of this study was to investigate the fracture loads and mode of failure of all-ceramic crowns fabricated using Top-Ceram and compare it with all-ceramic crowns fabricated from well-established systems: IPS-Empress II, In-Ceram. MATERIALS AND METHODS Thirty all-ceramic crowns were fabricated; 10 IPS-Empress II, 10 In-Ceram alumina and 10 Top-Ceram. Instron testing machine w...
متن کاملEffect of Different Cement Colors on the Final Color of Ips Empress Ceramic Restorations
In this study, the effects of the color of different post-core materials and different colored cements on the color and esthetic of all-ceramic restorations were investigated. Three groups of post-cores (ceramic, Cr-Ni and Cr-Ni + opaque), one sample per each group, were prepared as discs 14 ± 0.05 mm in diameter and 1.5 ± 0.05 mm in thickness. A total of 40 cement samples, 10 per each group (o...
