Abstract

Denture breath is eliminated from removable dental prostheses, e.g. dentures or orthodontic appliances by applying to the dental prostheses a solution of a water insoluble, organic solvent soluble hydrophilic polymer containing a flavoring agent; preferably the solution is applied as an aerosol. The polymers are preferably hydroxy lower alkyl acrylate or methacrylate polymers. Saccharin can be employed in the formulation to eliminate an initial burning sensation. Dentures can be cleaned by applying to them a solution of the same type of polymer having a bacteriostatic agent or disinfectant in the formulation.

Claims

2. A removable dental prosthesis according to claim 1 wherein the entrapped active agent comprises a flavoring agent.

3. A removable dental prosthesis according to claim 1 which is a full or partial denture.

4. A removable denture according to claim 3 wherein the active agent comprises a flavoring agent.

5. A removable denture according to claim 4 wherein the polymer is selected from the group consisting of hydrophilic polymers of hydroxy lower alkyl acrylates, hydroxy lower alkyl methacrylates, hydroxy lower alkoxy lower alkyl acrylates and hydroxy lower alkoxy lower alkyl methacrylates.

6. A removable denture according to claim 5 wherein the polymer is a copolymer of 80 percent hydroxyethyl methacrylate and 20 percent butyl acrylate.

7. A removable denture according to claim 4 including saccharin as a portion of the entrapped active agent.

8. A removable denture according to claim 3 including a bacteriostatic or germicidal agent as the active agent entrapped in the polymer.

9. A removable denture according tO claim 8 wherein the bacteriostatic or germicidal agent is a nascent oxygen providing compound.

10. A removable denture according to claim 9 wherein the nascent oxygen providing compound is a perborate or persulfate.

11. A removable denture according to claim 10 wherein the entrapped active agent includes a flavoring agent.

12. A removable denture according to claim 8 wherein the polymer is selected from the group consisting of hydrophilic polymers of hydroxy lower alkyl acrylates, hydroxy lower alkyl methacrylates, hydroxy lower alkoxy lower alkyl acrylates and hydroxy lower alkoxy lower alkyl methacrylates.

13. A removable dental prosthesis according to claim 1 wherein the film has a thickness of up to 2 mils.
