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.

The present invention relates to a tooth whitening system (10), comprising a light source (30), a light detector (40), and a processing unit (50). The light source is configured such that a wavelength of the light emitted is adjustable over a wavelength range of operation. The detector is configured to detect light emitted from the light source. The processing unit is configured to control the light source to adjust the wavelength of the light emitted by the light source and determine a measure of absorption light detected that was emitted from the light source as the wavelength is adjusted. The processing unit is configured to utilize the determined measure of absorption to operate the light source at a wavelength at a peak in absorption.

A device for the drying of tooth or bone surfaces includes a radiation source for irradiating the tooth or bone surface to be dried, a temperature sensor and/or a humidity sensor.

Provided herein are curable compositions for use in a high temperature lithography-based photopolymerization process, a method of producing crosslinked polymers using said curable compositions, crosslinked polymers thus produced, and orthodontic appliances comprising the crosslinked polymers.

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.

An implant and abutment tooth assembly includes an implant, a rotatable connector, a screw bolt, and a photocurable resin capsule. The implant includes a threaded section and a rotatable adjustment seat, wherein the rotatable adjustment seat has an upper connection portion. The upper connection portion has a groove, two spherical portions, and a receiving trench. The rotatable connector includes a spherical rotation face, two end faces, an abutment, an internal screwing section, and a stepped notch. The screw bolt includes an external screwing section, a rotary head, and a force segment. The external screwing section is screwed with the internal screwing section of the rotatable connector, and the rotary head is movably received in the stepped notch of the rotatable connector. The photocurable resin capsule includes 0.1 g to 0.8 g of light-cured resin and is accommodated in the receiving trench of the implant.

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.

Disclosed herein are devices, systems, and method for preconditioning lingual tissue for lingual orthodontic treatment, including the application of lingual braces. Protuberances may be affixed to the lingual surfaces of one or more of a patient's teeth prior to the introduction of an orthodontic appliance to allow time for the tongue to adapt to the presence of foreign structures. The protuberances may promote keratinization of the lingual tissue. The protuberances may be removed prior to the application of the orthopedic appliance. The protuberances can be pre-fabricated or fabricated in situ on the surfaces of the teeth. The protuberances may be any suitable material, including metal, polymer, or ceramic.
