Claims
- 1. A method of dental treatment comprising the steps of:
- cleansing the dental surface to be repaired;
- applying a photopolymerizable composition to the dental surface comprising an acrylate based adhesive material, and a photoinitiator, wherein said photoinitiator comprises an ionic dye-counter ion compound capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization of said acrylate based adhesive material;
- exposing the dental surface to actinic radiation to initiate photopolymerization; and
- curing said adhesive material.
- 2. The method according to claim 1 wherein said photoinitiator is a cationic dye-borate anion complex.
- 3. The method according to claim 1 wherein the actinic radiation is visible light.
- 4. The method according to claim 3 wherein the visible light is provided from either a broad band visible light source or a laser.
- 5. The method according to claim 1 further comprising the steps of:
- etching the dental surface with acid; and
- coating a bonding agent onto the dental surface; wherein said etching and coating steps are performed prior to said exposing step.
- 6. The method according to claim 1 further comprising the step of applying and molding an inert dental restoration material onto said photopolymerizable composition; wherein said applying and molding step is performed prior to said exposing step.
