Abstract
The invention relates to the application of photon energy to energize dental materials to enhance their physical handling characteristics, efficacy, ability to be delivered, reactivity, polymerization, and/or post-cure mechanical properties, among other attributes.
Claims16
A photopolymerizable dental composition comprising:
- unreacted monomer(s),
- filler(s),
- at least one photoinitiator, and
- a photon energy absorption enhancer that increases one or more properties selected from:
- energy conversion efficiency from photon energy to heat, and
- increasing a heating rate of a dental photopolymerizable material,
- wherein the photon energy absorption enhancer does not impart an unnatural tooth color to the photopolymerizable dental composition after photopolymerization, and wherein the at least one photoinitiator and photon energy absorption enhancer are activated by distinctly different photon energy spectra.
4 more elements
A photopolymerizable dental composition comprising:
- unreacted monomer(s);
- filler(s);
- at least two photoinitiators, wherein at least one of the two photoinitiators is activated by photon energy within a range of 0.49 eV-1.90 eV (2500 nm-650 nm), and at least one of the other photoinitiator(s) is activated by photon energy outside of 0.49 eV-1.90 eV (2500 nm-650 nm);
- at least one co-initiator, wherein the at least one co-initiator consists of a borate derivative;
- wherein the at least two photoinitiators and at least one co-initiator do not impart an unnatural tooth color to the photopolymerizable dental composition after photopolymerization.
