A medium for a dental structure includes a first portion having a first physical property arranged to connect with a first dental component of the dental structure; and a second portion having a second physical property arranged to connect with a second dental component of the dental structure, wherein the combination of the first portion and the second portion is arranged to minimize stress established between the first dental component and/or the second dental component when the first dental component combines with the second dental component.

The present disclosure relates to devices, methods and kits for accelerating the rate of whitening of teeth.

The mouthpiece includes an arch-shaped guard having an inner surface. The inner surface is contoured to follow a shape of a dentition. The arch-shaped guard is sized to span at least a portion of upper teeth and a portion of lower teeth in the dentition. The mouthpiece includes a bite plate positioned along the inner surface and dividing the arch-shaped guard into an upper and lower portion. The mouthpiece includes a first light array arranged along the lower portion of the arch-shaped guard, and a second light array arranged along the upper portion of the arch-shaped guard. The first and second light arrays are arranged at offset distances from the bite plate where the offset distance of the second light array is greater than the offset distance of the first light array. The first and second light arrays are arranged to direct light onto the upper and lower teeth, respectively.

The invention relates to medicine, namely to dentistry and is intended to reinforce composite materials used for elimination various defects of hard dental tissues of carious and non-carious origin in the process of direct/indirect, reinforced/unreinforced composite restoration. The claimed method includes vibrational mechanical activation of composite materials by a vibrational impact on portions of composite material shaped by manual mechanical activation (e.g., roll/ball) and applied layer by layer to a defect area. A device for vibrational mechanical activation of a composite material includes at least one working part for applying a composite material to a defect, the working part fixedly attached to a handle, which is connected by a framework to a micromotor that creates vibration which are transferred via the working portion to a layer of composite material by distributing the same across the entire surface of the defect and achieving the simultaneous surface plastic deformation thereof.

The invention relates to the application of photon energy to energize dental materials to enhance their physical handling characteristics, efficacy, ability to be delivered, reactivity, polymerization, and/or post-cure mechanical properties, among other attributes.

A curing light may include a housing sized and configured for placement over a tooth. A first facet positioned within the housing may have a first LED mounted thereon, a second facet positioned within the housing may have a second LED mounted thereon, and a third facet positioned within the housing may have a third LED mounted thereon.

A device, method, and system are provided for treating the oral cavity. The device includes a mouthpiece suitable for implementing a dental treatment, wherein the mouthpiece includes one or more stock elastomeric dental cover layers suitable for forming and maintaining a treatment cavity having a vacuum fluid seal, wherein the dental cover layers includes a layer over all the surfaces of the upper teeth and surrounding gums and/or a layer over all the surfaces of the lower teeth and surrounding gums, wherein each of the layers includes one or more hardened rigid or semi-rigid sections for enabling selected and/or differential collapsibility of the cover layers when exposed to vacuum pressure; and one or more treatment supply layers, and one or more flow channels in fluid communication with the treatment cavity so that the treatment supply layer can deliver and/or remove one or more treatment fluids from the one or more fluid sealed treatment cavities.

A set for at least one of gluing, bonding, modeling and repairing of an object. The set includes a housing with a first end, a second end, and a reservoir, a light-curable material arranged in the reservoir, and a lamp which emits a light having a wavelength or a spectrum of wavelengths at which the light-curable material is selectively cured and which is coupled to the housing at the second end so that the light emitted by the lamp is only emitted in a direction which faces away from the first end. The reservoir has an exit opening which selectively discharges the light-curable material at the first end. The housing is completely impermeable to light.

A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode portion of the curing light. The device body includes a proximal gripping end and a distal head end. The device body is formed from a thermally conductive body material. Excellent heat conduction away from the LED dies is achieved using a thermally conductive layer disposed over the device body. The thermally conductive layer serves as a conduit to quickly conduct heat away from the LED dies for dissipation within the material of the device body In this manner, the material of the device body serves as a highly efficient heat dissipater. The surface area coupling the thermally conductive layer to the device body is sufficiently large that a majority (e g, substantially all) of heat being conducted by the thermally conductive layer is transferred to the device body during operation of the device.
