INTRODUCTION

• 1965 mclean and Hughes

• Opened the world of metal-free

ceramics

• oxide ceramics containing oxidizing components only, but also

commonly referred to as ceramics and the mixed oxide

components

• http://www.ivoclarvivadent.us/en-us/products/alloys/predominantly-base-alloys/nickel-chromium/colado-nc

• They are polycrystalline materials with little or no vitreous

phase, which is the weak part of the porcelain. Due to its high

opacity are used as internal caps ceramic restorations.

• These authors feldspathic porcelain incorporated significant

amounts of aluminum oxide reducing the proportion of quartz.

The result was a mixed material having a microstructure in which

the alumina, having a high melting temperature, remained

suspended in the matrix.

COMPOSITION

• incorporated 50% aluminum oxide feldspathic porcelain

• (The presence of alumina causes a decrease glass to its own characteristics, which is less brittle and reduces the risk of devitrification process of crystallization of the ceramic what becomes brittle and opaque to lose amorphous or glassy structure

• (- Quartz) mass hardener:The quartz constitutes the crystalline phase.

• It created a more effective

reinforcer twice the feldspathic
