The peripheral outline of a model dentition extends into the thickness of the sealing strip to form a receptacle. A border of the sealing strip completely surrounds the outline. The receptacle is filled with a dental preparation to be administered and the sealing strip is overlaid with a film. In use, the film is removed, the system is bent to an arch shape and the outline is registered with the user's buccal dentition. Lateral force is applied in a lingual direction against the base strip to reshape the sealing strip for sealing contact of the border against the periphery of the user's buccal dentition, while leaving the preparation in contact with remaining buccal surfaces. ## Claims ### Claim 1 A dental preparation delivery system comprising a sealing strip formed of a soft malleable wax and a base strip, the base strip having a higher elastic modulus than the sealing strip, the strips being adhered to one another, a receptacle extending into the thickness of the sealing strip, the receptacle comprising a peripheral outline of a dentition, the peripheral outline being defined by a continuous internal wall within the sealing strip, the peripheral outline being surrounded by a border, wherein i) the receptacle is filled with a dental preparation; ii) when said sealing strip is overlaid with a removable film it forms a chamber encasing said dental preparation; and iii) the dental preparation can be administered to buccal surfaces of a user's dentition by registration of the peripheral outline with the buccal surfaces and urging the base strip against the buccal surfaces to reshape the sealing strip border to the contours of the user's dentition. ### Claim 2 (depends on 1) A dental preparation delivery system of claim 1 wherein the sealing strip is formed of dental wax. ### Claim 3 (depends on 2) A dental preparation delivery system of claim 2 wherein the base strip is formed of wax. ### Claim 4 (depends on 1) A dental preparation delivery system of claim 1 wherein the peripheral outline is in the shape of a model dentition. ### Claim 5 (depends on 1) A dental preparation delivery system of claim 1 wherein the internal wall extends completely through the thickness of the sealing strip, a portion of the base strip being in registration with the peripheral outline, the internal wall and the portion of the base strip in registration with the peripheral outline forming the receptacle. ### Claim 6 (depends on 1) A dental preparation delivery system of claim 1 wherein the delivery system is bent into an arch shape for administration of the dental preparation. ### Claim 7 (depends on 1) A dental preparation delivery system of claim 1 wherein the dental preparation is selected from the group consisting of a bleaching agent, a desensitizing agent, an anticariogenic agent, an antimicrobial agent and a fluoride. ### Claim 8 (depends on 1) A dental preparation delivery system of claim 1 wherein the internal wall extends partially through the thickness of the sealing strip, leaving a portion of the sealing strip as a floor surrounded by the internal wall, the internal wall and the floor forming the receptacle. ### Claim 9 (depends on 1) A dental preparation delivery system of claim 1 wherein a portion of the border adheres to the user's gingival tissue during administration of the dental preparation. ### Claim 10 (depends on 1) A dental preparation delivery system of claim 1 wherein a portion of the border adheres to tooth surfaces adjacent occlusal surfaces of the user's dentition during administration of the dental preparation. ### Claim 11 A dental preparation delivery system comprising a laminate formed of a the sealing strip and a base strip, sealing strip being soft and malleable, the base strip having a higher elastic modulus than the sealing strip, the strips being adhered to one another, a receptacle extending into the thickness of the sealing strip, the receptacle including a peripheral outline in the shape of a model dentition, the peripheral outline being defined by a continuous internal wall within the sealing strip, the sealing strip including a border extending between the peripheral outline and the outer periphery of the sealing strip, a dental preparation filled within the receptacle, the delivery system further comprising a removable film overlay covering the dental preparation and the border and which forms a chamber encasing said dental preparation. ### Claim 12 (depends on 11) A dental preparation delivery system of claim 11 wherein the sealing strip is formed of wax and the base strip is formed of wax. ### Claim 13 (depends on 11) A dental preparation delivery system of claim 11 wherein the internal wall extends partially through the thickness of the sealing strip, leaving a portion of the sealing strip as a floor surrounded by the internal wall, the internal wall and the floor forming the receptacle. ### Claim 14 (depends on 11) A dental preparation delivery system of claim 11 wherein the dental preparation is selected from the group consisting of a bleaching agent, a desensitizing agent, an anticariogenic agent, an antimicrobial agent and a fluoride. ### Claim 15 (depends on 11) A dental preparation delivery system of claim 11 wherein the internal wall extends completely through the thickness of the sealing strip, a portion of the base strip being in registration with the peripheral outline, the internal wall and the portion of the base strip in registration with the peripheral outline forming the receptacle. ### Claim 16 (depends on 11) A dental preparation delivery system of claim 11 wherein the dental preparation comprises a bleaching agent. ### Claim 17 (depends on 11) A method of delivering a dental preparation with the dental preparation delivery system of claim 11, the method comprising the steps of: a) removing the film overlay, b) bending the delivery system to an arch shape to approximate the curvature of a user's dentition arch, c) registering the peripheral outline with the corresponding surfaces of the user's buccal dentition, and d) contacting and sealing surfaces of the user's buccal dentition with the dental preparation by applying lateral pressure in a lingual direction against the base strip to deform and shape the sealing strip until the border conforms to the shape of and adheres to the peripheral outline of the user's buccal dentition. ### Claim 18 (depends on 17) A method of delivering a dental preparation in accordance with claim 17, the method including the further step of: e) maintaining the delivery system in position for a prescribed treatment duration. ### Claim 19 (depends on 18) A method of delivering a dental preparation in accordance with claim 18, the method including the further step of: f) removing the delivery system after the prescribed treatment duration has expired. ### Claim 20 (depends on 12) A dental preparation delivery system of claim 12 wherein the sealing strip is formed of boxing wax and the base strip is formed of modelling wax or base plate wax. ### Claim 21 (depends on 3) A dental preparation delivery system of claim 3 wherein the sealing strip is formed of boxing wax and the base strip is formed of modelling wax or base plate wax. ### Claim 22 (depends on 1) A dental preparation delivery system of claim 1 wherein the base strip is formed of modelling wax or base plate wax.
