The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment formation structure. One dental attachment formation apparatus includes a body having a first surface shaped to conform to the contours of an exterior surface of a tooth and including a portion of the first surface shaped to accommodate an attachment that is to be attached to the exterior surface of the tooth and a light source attachment structure for attachment of a light source to the body.

A dental hand-held device (100), including a curing device (101) for curing a dental restauration material (103) with light in a first wavelength range; and a fluorescence excitation device (105) for exciting fluorescence of dental substance (107) with light in a second wavelength range.

A dental care device may include a light emitting device configured to emit light according to a selected function of multiple functions of operation. The dental care device may also include a sensor configured to output movement signals representing movement of the dental care device and at least one processor. The processor may be configured to perform operations including determine a first movement of the dental care device based on the movement signals and in response to the first movement of the dental care device and in response to the light emitting device having a first status, direct a change in a function of operation of the light emitting device. The operations may also include in response to the first movement of the dental care device and in response to the light emitting device having a second status, direct a change in a status of the light emitting device.

The invention relates to a light curing appliance, in particular a dental light curing appliance (10), with a light source and with a light emission element such as an optical waveguide (12), of which the light output end is intended in particular to be directed towards a material that is to be polymerized. It is provided with one or more control devices (16) for switching on the light source during a polymerization cycle, and with one or more sensors (20) or sensor combinations connected to the control devices (16). The sensor (20) is designed as a location sensor and/or as a motion sensor (20) which detects a movement of the light curing appliance (10), designed as a hand-held appliance, and sends signals reproducing the motion to the control devices (16).

An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises a lamp support structure comprising a lamp support surface and is formed of a first material. A flexible lamp is mounted to the lamp support surface so that a light emitting surface of the flexible lamp assumes a concave curvature, thereby forming a lamp assembly. A guard component is overmolded to the lamp assembly. In one embodiment, the oral treatment device may be a teeth whitening device.

A method of producing a custom dental anchor application appliance may be provided. The appliance may be for mounting one or more anchors to teeth of a patient. The appliance may be for use in orthodontic aligner treatment. The method may include forming a dental appliance. The forming may be done using a three-dimensional printing approach. The appliance may include a body. The body may include at least one anchor-locating area. The anchor-locating area may be shaped to conform to a mounting area on a surface of a tooth. The appliance may include a receiving structure. The receiving structure may be configured to removably support a dental anchor. The dental anchor may be of a predefined configuration in a fixed position and orientation relative to the body.

The specification discloses a dental curing light including 1) a light engine, 2) a coaxially aligned, camera-based viewing system, and 3) a control system providing a variety of safety features and simplified, operator-friendly operation. The camera's field of view (FOV) is coaxial with the centerline of the curing beam of the light engine. The curing light includes a multi-planar dichroic mirror (MDM) providing viewing and light beam direction aligned with the target. The MDM provide multiple images to the camera from different angles. The camera provides real-time measurement of light intensity reflected back from the targeted surface. Using the multiple image portions reflected by the multi-planar dichroic mirror, the control system computes the distance between the curing light and the target. The reflected intensity and the calculated distance enable the control system to compute a light engine irradiance to achieve a desired irradiance at the targeted surface.

The present invention discloses an oral scanner, including an outer casing, a reflector, a heat source, an optical module and a forced convection element. The outer casing has a cavity. The reflector is located at the front end of the cavity. The heat source is located in the outer casing. The optical module is located in the casing. A heat channel is formed between the optical module and the outer casing. The forced convection element is disposed in the heat channel and configured to forcedly dissipate the waste heat of the heat source to the cavity to heat the reflector. Thus, the temperature of the heat source can be reduced, and vapor will not be generated on the reflector heated by the waste heat.

The invention is directed to a light curing device, in particular for dental restoration materials, having a light source and a control device for the light curing device, which control device is capable of switching on the light source at different levels of power. The light curing device includes an actuation element which can be used to switch on the light curing device upon actuation by the user at a reduced dosage of light for pre-curing the dental restoration material. The control device in particular signalizes the reduced dosage.
