The present invention is directed to a method of making a teeth treatment device, the method including the steps of passing a substrate through a container having melted wax therein to form a wax saturated substrate; applying a quantity of bleaching solution to one side of the wax saturated substrate; joining a thin plastic sheet to the one side of the wax saturated substrate to form a plastic coated wax saturated substrate having a quantity of bleach; cutting the plastic coated wax saturated substrate having a quantity of bleach into individual strips having a predetermined configuration; and packaging the individual strips.

Teeth treatment device

A dental tray for treating teeth using upper and lower jaw patterns formed from dental wax. The patterns are thin, ranging from about 0.02 to 0.08 inches thick, with 0.04 inches preferred. The wax is capable of softening at body temperature. The patterns include a fold line formed along their lengths so an outer portion extends from the fold line about the length of the average person's front teeth, for example, about 0.625 inches. The inner portion is slightly smaller, for example, about 0.375 inches. The inner portions have gaps to permit the folded pattern to fit inside the patient's mouth. The inside of the tray may be textured to assist in holding bleaching material. The tray can be reused, and it is suitable for bleaching, fluoride treatment, stain removal, and other conventional dental procedures.

The instant invention relates to an anhydrous dentifrice (toothpaste, brushing gel, etc . . . ) The dentifrice is a homogeneous mixture of the following compounds: (1) organic polyols, such as glycerin; (2) cooked starch gelling agents; (3) mildly abrasive fillers such as silica, alumina and dicalcium phosphate; and, optionally, (4) compounds selected from the group consisting of anti-caries agents, anti-plaque agents, anti-calculus agents, bleaching agents, peroxide stabilizers, desensitizing agents, whiteners, anti-stain agents, breath fresheners, flavorants, sweeteners, colorants, buffers, surfactants, and anti-bacterial agents, with the proviso that if bleaching agents are employed then peroxide stabilizers must also be employed. Preferably, the dentifrice does not contain any gelling agent other than the cooked starch particles.

Starch thickened non-aqueous dentifrices

A substantially anhydrous gel useful for bleaching teeth comprising: (i) at least 25% by weight of organic polyol; (ii) less than 3% by weight polyacrylic acid thickening agent; (iii) at least 10% by weight carbamide peroxide (or a chemically equivalent amount of another bleaching agent, such as 3% by weight hydrogen peroxide); (iv) neutralizing agent; (v) chelating agents; (vi) desensitizing agent; and (vii) miscellaneous ingredients such as Cirtoxain&reg; and flavorants. The organic polyol is preferably glycerin. The polyacrylic acid thickening agent is preferably a carbomer. The desensitizing agent is preferably potassium nitrate, strontium chloride, potassium citrate, strontium nitrate, or a similarly effective alkali or alkaline earth metal salt of an organic or inorganic acid.

Desensitizing bleaching gel

A thixotropic, smooth-flowing liquid, bulk-water-free dentifrice gel/paste that contains a stable mixture of at least one of amylopectin containing discrete solid particles and modified amylopectin containing discrete solid particles, uniformly suspended in and wetted by an inert essentially anhydrous organic hydroxylated liquid matrix material, and which dentifrice gel/paste is characterized by a high surface sheen. Preferably, the modified homopolysaccharide discrete particles contain esterified amylopectin and/or esterified amylose. The dentifrice gel/paste can be used as a toothpaste, a bleaching gel and a brushing gel.

Dentifrice gel/paste compositions

A process for bonding a denture to the tissue surfaces of the jaw over which the denture is superimposed during use which comprises the steps of providing at the interface of the denture and the jaw's tissues, a liquid irreversible hydrocolloid of an alginate dental impression formulation, applying pressure to the denture so that it presses into the tissue surfaces and causes the liquid hydrocolloid to flow within such interface, and then allowing the hydrocolloid to solidify within the interface. Also described is a novel relatively-thin film, settable hydrocolloid denture aid and the set, cushiony, relatively-thin film denture aid obtained from it.

In the process of implanting a metal dental prosthesis into or on the alveolar bone, to provide anchorage or stabilization either to a tooth or to another prosthesis, which involves surgical exposure of the alveolar bone, providing means for (a) fixing a metal implant in the alveolar bone, and (b) fixing the metal implant to either a tooth or to the other prosthesis, and closing the exposure of the alveolar bone, the improvement which comprises including in respect to such means the step of applying to one or more portions of the implant or to the locus of the implant in the alveolar bone, a primary coating comprising a crosslinked resin that (i) optionally contains leachable fluoride and (ii) is biocompatible with osseous and non-osseous tissue, to effect direct bonding of the implant to the tooth or to the prosthesis, or to bone or to non-osseous tissue or a combination of them. A treated prosthetic is also described.

Dental implant process and treated prosthetic

A method and apparatus for heat-curing light-cured resins by means of placing the resin in an oven attachment coupled to a high intensity light source, such that heat generated by the light source raises the temperature within the oven attachment to at least 140.degree. C., and maintains the temperature above 140.degree. C. for at least 10 minutes. The oven attachment has a body fabricated from a rigid material having a relatively low thermal conductivity. The oven attachment is fashioned to fit over the light outlet of a conventional light source. The oven attachment is preferably held in place by the same mechanism that holds a light-curing 'wand' to the light source. The light source is turned on for a heating period of approximately 15 minutes, causing the temperature within an oven chamber within the oven attachment to rise. Upon completion of the heating period, the light source is turned off and the heat-cured restoration may be removed.

Method and apparatus for heat curing resin compounds

An adhesive composition useful for restoration comprising a finely-divided reinforcing filler, a polymerizable matrix material, a bonding agent, a coupling agent, and a thermal initiator.

Restorative dental adhesive composition

Two-part dental cement systems based on glass ionomers which are curable on exposure to light. The dental cement systems comprise a two-part blend of sodium N(p-tolyl)glycine-glycidyl methacrylate (Na NTG-GMA) and pyromellitic dianhydride-methyl methacrylate (PMDM) resins and glass ionomers.
