Abstract
Processes for forming dental materials that include applying a hardenable dental adhesive to a surface and a second hardenable dental composite to the dental adhesive. The hardenable dental composite includes at least two adjacent regions with different concentrations of a photoinitiator, at least two adjacent regions with different photoinitiators, or both.
Claims62
A process for forming a dental material adhered to a surface, the process comprising:
- applying a hardenable dental adhesive to the surface;
- applying a hardenable dental composite to the hardenable dental adhesive on the surface, wherein the hardenable dental composite comprises at least two adjacent regions with different concentrations of a photoinitiator;
- applying a radiation source to irradiate the hardenable dental composite, wherein hardening of a region furthest from the radiation source is initiated first;
- and
- hardening the hardenable dental adhesive to adhere the dental composite to the surface through the adhesive.
A process for forming a dental material adhered to a surface, the process comprising:
- applying a hardenable dental adhesive to the surface;
- at least partially hardening the hardenable dental adhesive;
- applying a hardenable dental composite to the at least partially hardened dental adhesive on the surface, wherein the hardenable dental composite comprises at least two adjacent regions with different concentrations of a photoinitiator;
- and
- applying a radiation source to irradiate the hardenable dental composite and adhere it to the surface through the adhesive, wherein hardening of a region furthest from the radiation source is initiated first.
