摘要:
A glass composition, containing barium oxide, which provides a source of leachable fluoride and which can be incorporated into a dental cement composition which, when cured, is radiopaque and translucent.
摘要:
A microfilled dental composite containing from about 30% to about 60% filler. The filler being sub-micron hydrophobic silica particles of about 0.01 - 0.04 micrometers in diameter. The filler is dispersed in ethoxylated bisphenol A dimethacrylate resin containing suitable aliphatic dimethacrylate diluents up to about 40% by weight and curing agents effecting curing.
摘要:
A fitted-resin composition useful for porcelain repair and as a dental composite and therefore made up of non-toxic materials and a method for repairing porcelain or teeth. The composition comprises a methacrylate functional resin usable in dental composites, powdered filler-colorant therein, at least one photoinitiator for the resin in an amount sufficient to initiate polymerization and complete it in depth within about half a minute when exposed to a visible-light output of at least 5,000 foot candies, the photoinitiator being an exciplex of (1) either 1,3-bornanedione or benzil and (2) either ethyl-4-dimethyl amino benzoate or ethyl-2-dimethyl amino benzoate, and at least one accelerator-free peroxide curing agent for the resin in an effective amount for completing polymerization within about one-half hour of any portion of the resin not receiving sufficient light to effectuate complete cure before then. The method comprises mixing the components together under ordinary indoor lighting conditions, emplacing the mixture within a few minutes of the mixing, and curing at least a substantial portion of the emplaced mixture in situ for one half-minute under intense visual-light illumination of at least 5000 foot-candles. Any resin then uncured by light is cured within the next half hour by the peroxide curing agent.
摘要:
The present invention relates to flexible wound dressings. More particularly, the present invention is directed to flexible wound dressings comprising ionomer resins. The invention involves treating the injured tissue with films comprising a special biocompatible crosslinked resin that optionally contains leachable healing and antibiotic agents.
摘要:
The invention relates to dental composites and porcelain repair material and to methods for making and using them. In particular, the present invention is directed to dual-cure composite dental cements comprising opaquing agents.
摘要:
A dental prosthesis and method of forming a dental prosthesis. The prosthesis comprises a pontic and huggers that conform to the surface of abutment teeth around a gap filled by the pontic. Installation of the prosthesis does not require damaging or altering the abutment teeth.
摘要:
A user-fabricated mouth guard wherein the user's teeth and gums are not directly exposed to the uncured mouth guard material. The uncured mouth guard material is pliant at room temperature and does not have to be heated to form and shape the mouth guard. The cured mouth guard can be pliant or rigid at room temperature. A kit and a method of forming the mouth guard are also disclosed.
摘要:
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 anticaries 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.
摘要:
A transparent, alcohol-free, aqueous oral rinse composition comprising more than 0.04 % by weight benzocaine, carbomer in an amount that is roughly equal to half the amount of benzocaine employed, and water. The composition relieves the soreness of aphthous ulcers and similar mouth sores.
