Patent ID: 7134875

Claim:
A process for forming a dental material adhered to an oral surface, the process comprising: applying a hardenable dental adhesive to an oral surface, wherein the hardenable adhesive comprises a first photoinitiator that absorbs radiation within a range of about 380 nm to about 450 nm; applying a hardenable dental composite to the hardenable dental adhesive on the oral surface, wherein the hardenable dental composite comprises a second photoinitiator that absorbs radiation within a range of about 450 nm to about 520 nm; irradiating the hardenable dental composite with radiation within a range of about 450 nm to about 520 nm to selectively harden the hardenable dental composite; and subsequently irradiating the hardenable dental adhesive with radiation within a range of about 380 nm to about 450 nm to harden the dental adhesive and adhere the dental composite to the oral surface; wherein neither the first photoinitiator nor the second photoinitiator absorbs radiation above about 520 nm.
