Patent ID: 8636928

Claim:
A method of making a dental restoration on a prepared tooth, comprising the steps of: a) providing a first polymerizable material, the first polymerizable material including a polymerizable acrylic compound having one or more semi-crystalline acrylic monomers and one or more acrylic oligomers; b) forming an uncured shape-stable first form from the first polymerizable material, the uncured shape-stable first form having a cavity therein; c) providing a second polymerizable material being different from the first polymerizable material, the second polymerizable material including a polymerizable acrylic compound having one or more semi-crystalline acrylic monomers and one or more acrylic oligomers; d) forming an uncured shape-stable second form from the second polymerizable material, the uncured shape-stable second form having a cavity therein being complementary to the cavity of the uncured shape-stable first form; e) placing the second form in the first form to form an uncured shape-stable multi-layered shell, wherein the uncured multi-layered shell having a cavity therein is configured so that it may be mounted over the prepared tooth; f) introducing a third polymerizable material into the cavity of the uncured multi-layered shell form, the third polymerizable material including a polymerizable acrylic compound having one or more semi-crystalline acrylic monomers and one or more acrylic oligomers; g) placing the uncured multi-layered shell form containing the third polymerizable material over a prepared tooth in a mouth of a patient; h) irradiating the uncured multi-layered shell form and the third polymerizable material with light to form a partially cured restoration inside of the mouth; and i) removing the partially-cured restoration from the tooth and irradiating the restoration with light outside of the mouth to form a fully cured restoration.
