CLEARFIL MAJESTY™ Posterior
CLEARFIL MAJESTY™ Posterior by Kuraray Noritake is a light-curing, nano-superfilled, radiopaque restorative posterior composite resin composed of nano and micro inorganic fillers treated with a proprietary new surface coating technology.
Indications for CLEARFIL Majesty™ Posterior
• Direct restorations for anterior and posterior teeth (Class I – V cavities)
• Correction of tooth position and tooth shape (e.g. diastema closure, dwarfed tooth, etc.)
• Intraoral repairs of fractured crowns/bridges
• Highest filler loading (92 wt%, 82 vol%)
• High surface hardness, close to human enamel (high wear resistance), but friendly against an antagonist tooth
• High mechanical properties (strength, durability) and high curing depth
• Low polymerization shrinkage and low thermal expansion
• Better marginal adaptation even for a long time period
• Easy handling
• Versatile, simple, accurate shade selection for posterior restorations
The new surface technology permits a larger quantity of nanofiller to be dispersed in the resin matrix, a matrix which consists of monomer and microfiller. The resulting resin matrix is reinforced with a filler loading of 92 wt% (82 vol%).
CLEARFIL MAJESTY™ Posterior has an improved high surface hardness close to that of human enamel (high wear resistance, but friendly against an antagonist tooth), high mechanical strength (compressive strength: 504 MPa,
flexural strength: 177 MPa), high durability, high curing depth, low polymerization shrinkage (1.5 vol%) and a low thermal expansion coefficient.
These features assure a reliable posterior restoration with better marginal adaptation and a restoration that will last. In spite of the extremely high filler loading, CLEARFIL MAJESTY™ Posterior also has an easy shapable consistency and the high refractive matrix also provides another essential benefit, a very minor transparency shift after light-curing.
