According to one aspect of the present invention, a lubrication box includes a first portion, a shaving aid material, and a second portion. The first portion of the lubrication box has a skin-engaging surface and at least one sidewall that, together, form a cavity. The skin-engaging surface includes at least two holes therethrough. The shaving aid material, which is optionally distributed in the cavity in a series of layers, is ultrasonically compressed into the cavity such that it at least partially fills at least one of the holes in the skin-engaging surface and at least a portion of the cavity. The second portion of the lubrication box is attached to the first portion such that the cavity is substantially closed. A gap exists between in the cavity between the shaving aid and the second portion of the lubrication box to permit the shaving aid material to expand during normal use.

The present application provides a glass composition comprising 10-50% by weight CaO, at least 15% and less than 50% by weight PO, less than 3% by weight AlO, less than 10% by weight LiO, NaO, and KO combined, and 0-60% by weight of SrO, MgO, BaO, ZnO, or combinations thereof; dental compositions comprising the glass composition, and methods of making and using such dental compositions.

According to one aspect of the present invention, a lubrication box includes a first portion, a shaving aid material, and a second portion. The first portion of the lubrication box has a skin-engaging surface and at least one sidewall that, together, form a cavity. The skin-engaging surface includes at least two holes therethrough. The shaving aid material is pre-formed in a pre-determined shape, placed in the first portion of the lubrication box, and then compressed. The second portion of the lubrication box is attached to the first portion such that the cavity is substantially closed. A gap exists between in the cavity between the shaving aid and the second portion of the lubrication box to permit the shaving aid material to expand during normal use.

The present application provides dental compositions, and methods of making and using dental compositions that include a calcium and phosphorus releasing glass. Such dental compositions can be useful for delivering ions to the oral environment.

The present application provides dental fillers, and methods of making and using dental fillers that include a treated surface that includes a caseinate. Dental compositions including such dental fillers can be useful for delivering ions to the oral environment. Dental compositions, and methods of using dental compositions that include a caseinate and a hardenable resin or a water-dispersible, polymeric film former are also provided.

A dental impression tray comprises a trough for receiving dental impression material and at least one retainer on at least a portion of an inner surface of the trough. The retainer comprises a plurality of anchoring elements, each of which comprises a first end, a second end, and an arc between the first and second ends. The first and second ends of the anchoring elements are connected to the inner surface of the trough, and the arcs project from the inner surface of the trough. The loop material of a hook and loop mechanical fastener is a particularly useful retainer.

A device for delivering medicaments to oral structures contains a flexible backing having a plurality of microstructures protruding from one surface of the backing, and a binder layer containing medicaments disposed on the backing and/or microstructures. Because the device contains microstructures that form obstacles or barrier that minimize the flow of medicaments away from the target oral structure, the medicaments stay at the desired longer thereby being more effective at treating the oral structure. One particularly useful application of the inventive device is for whitening teeth.

Medication delivery devices

An assembly for retaining medication in an oral medication delivery tray includes a substrate, a layer of adhesive extending across the substrate and a release liner initially connected to the layer of adhesive. The assembly also includes a tab portion connected to the layer of adhesive and extending past the substrate. The tab portion serves as a handle to facilitate separation of the layer of adhesive from the release liner as the substrate is pulled away from the release liner, so that the layer of adhesive remains on the substrate.

Medication retention assembly for oral delivery tray

A dental tray for delivery medication to oral structure is custom-made to closely match the configuration of the oral structure. A lingual wall of the tray includes a lingual edge section having an outer edge that is spaced in a gingival direction from the patient's gingival margin a certain distance in order to reduce the possibility of adverse effects as might be caused by movement of the patient's tongue. A buccolabial wall of the tray has an outer edge that is closely adjacent the patient's gingival margin in order to increase patient comfort, reduce gingival irritation and improve patient compliance during the course of treatment.

Custom tray for delivering medication to oral structures

A medication delivery tray provides a controlled release of medication to target dental structures in the mouth, such as the teeth and/or gingiva, while maintaining a high concentration of the active chemical over an extended period of time. The medication delivery tray includes a dental tray having a base, a buccal wall and a lingual wall defining an inner surface. At least one medication reservoir is located on the dental tray. Each medication reservoir includes a plurality of discrete support members projecting away from the medication reservoir to engage the dental structure of the patient. The support members are arranged to resist the flow of medication from the medication reservoir in a gingival direction. Each medication reservoir extends over the teeth and/or gum tissue of the patient when the medication delivery tray is placed over the patient's teeth.
