Effects of Different Polishing Protocols on Lithium Disilicate Ceramics [PDF]

Brazilian Dental Journal, 2015
Abstract: The aim of this study was to evaluate the effect of different polishing protocols on surface roughness and morphology of lithium disilicate ceramics (IPS e.max CAD). Fifty ceramic bars (2.0x3.0x2.5 mm) were produced and randomly divided into five groups (n=10), according to surface treatments: C: Control; Cer: Ceramaster (60 s); CW: cloth ...

Influence of Universal Adhesives With or Without Silane Compared to One‐Step and Two‐Step Silane Agents on Bond Strength to Lithium Disilicate

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the microshear bond strength (μSBS) to lithium disilicate achieved with universal adhesives (with and without silane) compared with one‐step and two‐step silanes, immediately (IM) and after thermocycling (TC). Chemical interaction (CI) was also assessed.

Wear behavior of pressable lithium disilicate glass ceramic [PDF]

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2015
AbstractThis article reports effects of surface preparation and contact loads on abrasive wear properties of highly aesthetic and high‐strength pressable lithium disilicate glass‐ceramics (LDGC). Abrasive wear testing was performed using a pin‐on‐disk device in which LDGC disks prepared with different surface finishes were against alumina pins at ...
