BACKGROUND The field of dental ceramics for CAD-CAM is enriched with a new innovative material composition having a porous three-dimensional structure of feldspathic ceramic infiltrated with acrylic resins.The aim of this study is to determine the mechanical properties of Polymer-Infiltrated-Ceramic-Network (PICN) and compare its performance with other ceramics and a nano-ceramic resin availabl...

Aim The aim of the present work was to compare the elastic properties and internal structure of 4 different CAD/CAM chairside materials, by the method of Scanning Impulse Acoustic Microscopy (SIAM). Methods Four chairside CAD/CAM materials with different structures from hybrid ceramic (VITA Enamic, VITA Zahnfabrik), feldspatic ceramic (VITABlocs Mark II, VITA Zahnfabrik), leucite glass-cerami...

In this study, production possibility of glass and glass-ceramic produced from granite was investigated. The composition of granite based glass bath mixture was 50 wt% granite, 25 wt% dolomite and 25 wt% sodium carbonate. Composition that was grounded and mixed in a ball mill for 2 h was melted at 1500 ◦C for 1 h. Glass samples were heat treated for crystallization to produce glass-ceramic mate...

The last 25 years have witnessed the introduction of a bewildering number of ceramic systems to the dental profession. Most of these systems have been introduced with little or no clinical testing. Laboratory studies of physical and mechanical properties of ceramics provide little predictive information regarding likely clinical survival rates. Early adopters of many of these new systems learne...
