Abstract
Abstract A method and agglomerated material for providing special effects in a dental restoration where the agglomerated material is a plurality of powdered particles of colorizing agents bound to form macroscopic shards for direct insertion into a soft, gel-like dental restoration preform to provide the special effects after glazing the preform.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
A method for providing colorization effects of hue, chroma and value in a dental restoration, said method comprising the steps of: (a) providing a dental restoration preform in a gelatinous state; (b) providing particulate colorizing agent from among at least one of silicon dioxide; aluminum oxide; sodium oxide; potassium oxide; stannic oxide; barium oxide; ferric oxide; boron oxide; magnesium oxide; silica; chromic oxide; cobalt oxide; iron oxide; manganese; stannous oxide; nickel oxide; tin oxide; titanium dioxide; vanadium oxide; zinc oxide; zirconium oxide and indium oxide; (c) providing a binder agent having a solvent, a plasticizer, and a binder; (d) mixing said binder and colorizing agents to form an agglomerate; (e) curing and hardening said agglomerate; (f) providing at least one macroscopic shard of a colorizing agent from said agglomerate; and (g) inserting said shard into said restoration preform to provide said restoration with a desired colorizing effect after glazing.
