  • DENTAL MATERIAL
    Publication number: 20090298966
    Abstract: The dental material contains a polymerizable dental resin of index of refraction n1, inorganic nano-scale solid particles of index of refraction n2, dental glass particles of index of refraction n3, and accessory substances to autopolymerize and light-cure the dental resin. The dental material exhibits a composite index of refraction n4 in the range of 1.56 to 1.70. The dental material imparts optimal esthetics to the tooth being restored and allows for application in substantially thick layers.

  • Shade guide for evaluating the optical appearance of a dental restoration
    Patent number: 6848904
    Abstract: The shade guide (1) consists of a colored polymerized composite material for evaluating the optical appearance of a dental restoration. The shade guide has a wedge-like shape and the composite material of which it is built up has a homogeneous structure. It has the advantage that it allows evaluation of the coloration of a dental restoration to be made with a curable composite material, particularly with a light curable composite material, before the restoration is performed.
