Posterior Solutions

ZirM	3M ESPE LAVA™ Plus	NP-CAD	IPS e.max®
ZirM all-zirconia crown. The colour comes from pre-tinted zirconia and is then stained and glazed. This is the most economical crown that we provide.	Lava™ Plus from 3M ESPE is a brand that we trust. Lava™ Plus colour comes from within. The crowns are custom stained before sintering creating a life-like restoration. With the aesthetics and strength of 1200mpa, Lava™ Plus is ideal for posteriors.	With the advent of CAD/CAM dentistry we can now mill Chrome cobalt metal in-house. By milling this metal we create a finished product with accuracy and purity that cannot be replicated by traditional casting techniques.	Lithium disilicate is strongest when pressed at minimum thickness of 1.0mm with a flexural strength of 400mpa.
