Fracture 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...

Objective: In this study, the effects of ceramic, chromium-nickel (Cr-Ni) and ceramic opaque sinterized on chromium-nickel (Cr-Ni+opaque) post-core materials and different colored (opaque white, white, yellow and brown) cements on final color of all-ceramics materials (In-Ceram, IPS Empress and IPS Empress II) were investigated. Material and Methods: Three groups of post-cores (ceramic, Cr-Ni a...

. AbstrAct Objective. In clinical practice, core material can be exposed after adjustments, which may result in loss of ceramic glaze. The objective of this study is to evaluate the effect of surface roughness on the flexural strength and fracture toughness of In-Ceram zirconia core material. Materials and methods. Forty In-Ceram zirconia specimens were prepared and divided into two main groups...
متن کاملMarginal Fit Metal-Ceramic and In-Ceram Single Crown Cement retained in Implant-supported Abutments.
INTRODUCTION This study evaluated the cervical fit of cemented metal-ceramic and In-Ceram implant-supported crowns, before and after the cementing procedure. MATERIALS AND METHODS Twenty crowns cemented on implant abutments are divided into two groups (n = 10): Group 1 -cemented metal-ceramic crowns and group 2 - cemented In-Ceram crowns. The marginal adaptations before and after cementation ...
متن کاملFunctional and esthetic rehabilitation with in-ceram alumina and zirconia system: a multidisciplinary approach.
UNLABELLED The development of all-ceramic systems following metalceramics restorations allowed simulation of natural dentition due to favorable esthetics and resistance. In-Ceram is an alternative when esthetics is primordial as well as resistance required in rehabilitation. However, an ideal smile is associated to not only shape, color, texture and translucency but also harmony with gingival t...
