A polymerization apparatus according to an embodiment of the present invention includes: a light irradiator; and a polymerization vessel. The light irradiator includes a first casing and a light source assembly. The first casing includes a light source chamber defined by cylindrical side walls, a ceiling, and a floor including a light-transmissive window member. The light source assembly includes a base having a light-emitting surface on which a plurality of light-emitting diodes is disposed in a predetermined pattern and a heat-dissipating surface to which a heat sink is joined, and the light source assembly is disposed within the light source chamber so that the light-emitting surface faces the light-transmissive window member. The polymerization vessel includes a polymerization cup and a second casing. The polymerization cup has a frustoconical or substantially frustoconical shape that opens upward and increases in diameter upward, and is capable of housing an object therein. The second casing is a bottomed cylindrical or box-shaped casing having an opening at the apex thereof, the polymerization cup being attachably/detachably housed in the second casing via the opening. In this polymerization apparatus, light that has been emitted by the plurality of light-emitting diodes of the light irradiator and has passed through the light-transmissive window member is applied to the inside of the polymerization cup of the polymerization vessel.

A dental matrix for forming a crown on a tooth includes a body having a expandable tab, which allows the diameter of an opening to be expanded for removal of the matrix from the formed crown.

A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode (LED) portion of the curing light. The device body is one-piece body formed from a continuous seamless piece of thermally conductive material extending between a proximal end and a distal end. The one-piece body includes a gripping handle portion extending to the proximal end and a light-emitting head portion extending to the distal end. The one-piece thermally conductive body acts as a heat sink to efficiently conduct heat away from the LED dies during use. The one-piece body eliminates problems of multi-segmented curing lights that include one or more joints between adjacent segments. Eliminating joints increases thermal conductivity of the body, eliminates crevices where microbes can grow, and eliminates the risk of accidental separation if the curing light is dropped.

An apparatus for treatment of teeth, including one or more dental treatment applicators having at least two walls and a floor, the walls and floor defining a well configured to accommodate at least one human dental arcade and an active agent. Furthermore, one or more energy-applying elements such as electrodes or light sources are located on at least one of the walls.

A smart lighting system for applying light to teeth in the context of tooth whitening and teeth that have been provided with a light-curable whitening varnish. The system includes a light-generating unit, a light-patterning unit, a mouth imaging unit, a mouth image sensing unit, and an image processing and control unit, and is adapted so as to allow the image processing and control unit to adjust the light-patterning unit on the basis of information obtained from the mouth image sensing unit. By doing so, prior to allowing the light-generating unit to emit light, it can be ensured that light emitted to assist tooth whitening, does not affect soft tissue.

Provided herein is an adapter for a dental curing light. The adapter can restrict or otherwise concentrate light as it is emitted from the dental curing light making the beam of light more focused to a specific portion of a tooth rather than radiating an entire tooth. The adapter can have different customizable shapes and sizes which is beneficial for adhering attachments commonly used with orthodontic aligners to a tooth.

A dental crown and method of use thereof. According to the method provided herein, a dental crown is selected having an appropriate size and shape and an internal contour. The tooth to which the crown is to be applied is prepared to have an external contour. Composite material is injected into the internal contour of the dental crown. The dental crown is placed over the prepared tooth and the deposited composite material is cured using light.

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.

The present invention relates to methods for curing polymeric dental appliances comprised of partially cured photopolymerizable components, especially for additively manufactured denture base and artificial tooth components utilized in the production of full and partial dental prostheses. In particular, the invention relates to methods of utilizing a curing apparatus having one or more controllable heating sources and one or more controllable LED light sources to achieve specific preheating and light curing conditions for more effectively converting partially cured photopolymerizable components from a partially cured state to a final cured state.

A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.
