An applicator for oral treatment preparations comprises a membrane covered core having an arched vertical panel and a lateral panel with a generally "L" shaped transverse cross section. The core is formed of a modeling material such as wax, which is soft and pliable and which conforms to the contour
An applicator for oral treatment preparations comprises a membrane covered core having an arched vertical panel and a lateral panel with a generally "L" shaped transverse cross section. The core is formed of a modeling material such as wax, which is soft and pliable and which conforms to the contours of oral surfaces against which it manipulated. The vertical panel is pressed against buccal dentition surfaces to be treated. The lateral panel is then manually bent around occlusal surfaces and pressed against lingual dentition surfaces. The oral treatment preparation for administration may be coated on the membrane prior to fitting or microencapsulated within the core to pass through the membrane for administration. Alternately the applicator is removed after initial shaping or fitting, the oral treatment preparation is applied to the membrane and the applicator is then reinserted.

Having thus described the invention, the following is claimed: 1. An applicator for topical administration of an oral treatment preparation, the applicator comprising an arch shaped pliable core, the core including a vertical first panel and a lateral panel, the core being formed of a modeling mate
Having thus described the invention, the following is claimed: 1. An applicator for topical administration of an oral treatment preparation, the applicator comprising an arch shaped pliable core, the core including a vertical first panel and a lateral panel, the core being formed of a modeling material capable of obtaining dental impressions by manual manipulation, a first face of the vertical panel and a first face of the lateral panel being covered with a plastic film membrane, the applicator further including an arch shaped removably positioned backing plate, the backing plate having a generally "L" shaped transverse section including a vertical wall abutting the vertical panel of the core and a horizontal ledge abutting at least a portion of the lateral panel whereby the first face of the vertical panel may be urged against buccal dentition surfaces to impress such surfaces in the vertical panel and the first face of the lateral panel may be bent against lingual dentition surfaces to impress such surfaces in the second panel so that an oral treatment preparation positioned between the core and one or more of the buccal and lingual surfaces is effectively administered. 2. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 1 wherein the core is encased in the membrane. 3. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 1 wherein the membrane is permeable. 4. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 1 wherein the modeling material comprises wax. 5. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 1 wherein the vertical panel includes impressions of buccal dentition surfaces and the lateral panel includes impressions of lingual dentition surfaces, the applicator further including a layer of oral treatment preparation. 6. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 5, the oral treatment preparation being positioned over the membrane. 7. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 1 wherein the core has a thickness in the range of approximately 쩍 mm to 3 mm. 8. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 7 wherein the core has a substantially uniform thickness throughout. 9. A method of administering an oral treatment preparation, the method comprising the steps of: a) providing an applicator having a pliable core formed of modeling material, the core having a pair or panels and a plastic film overlay; b) providing the applicator with a removable barking plate having a generally "L" shaped transverse section including a vertical wall abutting one of the panels and a transverse ledge abutting at least a portion of the other panel; c) inserting the applicator core into an oral cavity; d) impressing buccal dentition surfaces in the one panel; e) impressing lingual dentition surfaces in the other panel; and f) positioning an oral treatment preparation between selected dentition surfaces and the impressions thereof formed in the panels. 10. A method of administering an oral treatment preparation in accordance with claim 9 wherein step f) is performed by: i) removing the applicator core from the oral cavity, ii) coating impressions of the core corresponding to the selected dentition surfaces with the oral treatment preparation, and iii) repositioning the core within the oral cavity. 11. A method of administering an oral treatment preparation in accordance with claim 9 wherein step f) is performed by: i) removing the applicator core from the oral cavity, ii) coating the selected dentition surfaces with the oral treatment preparation, and iii) repositioning the core within the oral cavity. 12. A method of administering an oral treatment preparation in accordance with claim 9 wherein step f) is performed by coating the selected dentition surfaces with the oral treatment preparation prior to step c). 13. An applicator for topical administration of an oral treatment preparation, the applicator comprising an arch shaped soft pliable core, the core including a vertical panel and a lateral panel and having a generally "L" shaped transverse section, the core being formed of a modeling material capable of obtaining dental impressions by manual manipulation, the applicator further including an arch shaped removably positioned backing plate, the backing plate having a generally "L" shaped transverse section including a vertical wall abutting the vertical panel of the core and a horizontal ledge abutting at least a portion of the lateral panel, whereby a first face of the vertical panel may be urged against buccal dentition surfaces to impress such surfaces in the vertical panel and the lateral panel may be bent around occlusal dentition surfaces and a fist face of the lateral panel may be urged against lingual dentition surfaces to impress such surfaces in the lateral panel so that an oral treatment preparation positioned between the core and one or more of the buccal, occlusal and lingual surface is effectively administered. 14. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 13, wherein the first face of the vertical panel and the first face of the lateral panel are covered with a membrane. 15. An applicator for topical administration of an oral treatment preparation as constructed in accordance with claim 13, wherein the modeling material comprises wax. 16. A method of administering an oral preparation, the method comprising the steps of: a) providing an applicator having a carrier with a substantially "L" shaped transverse cross section throughout and a core with rheological characteristics suitable for implementation as a dental impression material, b) adhering a plastic film membrane over at least one face of the core, c) obtaining in the core impressions of buccal surfaces of selected target teeth by inserting the applicator in an oral cavity and applying lateral pressure against the carrier to force the core against the buccal surfaces of the selected target teeth, and d) positioning a layer of preparation between the buccal surfaces and the impressions formed in the core. 17. A method of administering an oral preparation in accordance with claim 16 wherein the preparation is carried in the core and the membrane is perforated, the step of positioning including: i) extruding the preparation through the perforations. 18. A method of administering an oral preparation in accordance with claim 16 wherein step d) is performed by: i) removing the applicator from the oral cavity, ii) coating the impressions of the buccal surfaces with the preparation, and iii) repositioning the core within the oral cavity. 19. A method of administering an oral preparation in accordance with claim 16 wherein step d) is performed by: i) removing the applicator from the oral cavity, ii) coating the buccal surfaces of the selected target teeth with the preparation, and iii) repositioning the core within the oral cavity.
