The present invention relates to a primer composition that may be applied to tissue in order to increase bond strength between the tissue and a patch, filler or a supporting material. The primer comprises a dithiol component and an allyl containing component together with a photo initiator.

The invention relates to a polymerization and post-tempering device (10) for tempering, in particular post-tempering, dental restoration parts (54) made of polymerizable plastics. At least one light source (38) which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door (14) to the light chamber are provided. The door (14) comprises a window (20) with a window pane (22) which consists of at least two layers (56, 58) whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.

An oven (100) for heating a dental object (101), having a chamber (103) for receiving the dental object (101); a radiation source (105) for emitting radiation having a wavelength smaller than 350 nm into the chamber (103); and heating means (113) for heating the dental object (101) in the chamber (103).

A laser device for dentistry has a body, a light source group, and a light guiding pipe. The body has an outer casing, an operating module, and a controlling module. The light source group is disposed in the body and has multiple light-emitting elements, a reflector, a collimating mirror, and a focusing mirror. Each light-emitting element is a laser diode, is disposed at a connecting portion of the body and is electrically connected to the controlling module. The reflector is mounted around the light-emitting elements. The collimating mirror is disposed on a side of the reflector away from the light-emitting elements. The focusing mirror is disposed on a side of the collimating mirror away from the reflector. The light guiding pipe is detachably connected to the connecting portion of the body and is located on a front side of the light source group.

An oral treatment device and a method of using the same. The oral treatment device includes an intraoral mouthpiece configured for placement into a mouth of a user, which includes a lamp having a top edge and a bottom edge, a plurality of first electromagnetic radiation emitting elements that emit light in a first wavelength when activated, and a plurality of second electromagnetic radiation emitting elements that emit light in a second wavelength when activated. The first electromagnetic radiation emitting elements are positioned along the lamp to emit light onto the user's teeth and the second electromagnetic radiation emitting elements are positioned along the lamp to emit light onto the user's teeth.

A device for use by a clinician includes a tip structure that is configured to extend from a handle and to be inserted into a patient's mouth and at least one light source that is capable of emitting incoherent actinic radiation from the device. The light source is on the tip structure or within the handle. A light device includes a shell that is configured to engage an orthodontic bracket while the orthodontic bracket is attached to a tooth and at least one light source is embedded in the shell and is capable of emitting incoherent actinic radiation. A method of debonding an orthodontic appliance from a tooth includes exposing an adhesive secured to the tooth to incoherent actinic radiation that reduces a bond strength of at least a portion of the adhesive and separating the orthodontic appliance from the tooth at the portion of the adhesive having reduced bond strength.

The present invention relates to a primer composition that may be applied to tissue in order to increase bond strength between the tissue and a patch, filler or a supporting material. The primer comprises a dithiol component and an allyl containing component together with a photo initiator.

A three-dimensional printing system includes a resin vessel, a support tray, a motorized carriage, a light engine, and a controller. The resin vessel has a lower side with a transparent sheet which provides a lower bound for photocurable resin contained within the vessel. The support tray has a lower face for supporting an object being fabricated. The motorized carriage is for supporting and vertically positioning the support tray. The light engine is for projecting radiation up through the transparent sheet to a build plane. The controller operates the motorized carriage and the light engine to fabricate the object. The object includes a vertical arrangement of dental arches suspended from the lower face and a plurality couplings that connect pairs of the dental arches.

A light-emitting device (1) for curing dental materials. The device comprises an activator (10) and a light output (4) and is adapted to operate the light output at a first or a second operating mode dependent on the presence of a second user input within a monitoring time period after a first user input. The device allows for convenient operation by a user and helps in reliably curing dental materials.

Presented herein is an optical filter system for visible light, which has a first average transmittance T.sub.1 between a limit wavelength λ.sub.G and a wavelength of 700 nm and a second average transmittance T.sub.2 between a wavelength of 380 nm and the limit wavelength λ.sub.G. In this case: 410 nm<λ.sub.G<520 nm and 0.05
