A system includes a partial enclosure configured to hold resin. The system further includes one or more structures configured to at least partially cover the resin. The one or more structures are configured to prevent evaporation of the resin. The system further includes a build platform configured to support an object that is being formed from layers of the resin. A first blade is configured to provide the layers of the resin to form the object on the build platform.

An embodiment of the present invention provides an indirect bonding device for an orthodontic apparatus, the indirect bonding device comprising: a jig main body part in a form that covers the tooth surface of a subject undergoing a procedure; an accommodation part having grooves capable of accommodating an orthodontic bracket into the internal space of the jig main body part; and a discharge hole part which is formed as at least one hole passing through the inner and outer portions of the jig main body part and through which a bonding agent excessively introduced into the orthodontic bracket is discharged.

A system is directed to repositioning teeth and includes a first three-dimensional image showing an initial position in which a plurality of teeth are unaligned, and a second three-dimensional image shows a final position in which the plurality of teeth are aligned. The system also includes a plurality of structural domes for respective attachment to the plurality of teeth, the plurality of structural domes being customized and formed based on at least one of the first three-dimensional image and the second three-dimensional image. Each chair-side fabricated dome has at least one internal tunnel that is unaligned with an adjacent internal tunnel in the initial position. A continuous wire is inserted through each internal tunnel of the plurality of structural domes and applies a force to the plurality of structural domes such that adjacent internal tunnels are in alignment with each other in the final position.

A current digital dental model is received that includes a representation of the set of physical teeth for the patient with the current dental appliance attached to the physical teeth or oral cavity. The current digital dental model is a direct digital scan of the set of physical teeth and the current dental appliance. The physical teeth are at a position in treatment when all or a part of the current dental appliance is desired to be removed from one or more of the set of physical teeth and it is desired to use a subsequent appliance. The current digital dental model is created based a new digital dental model that includes the representation of the set of physical teeth without including the current dental appliance.

Trays for indirect bonding orthodontic appliances to a patient's teeth and methods of bonding orthodontic appliances to patient's teeth, using a custom patient-specific mold body that optimizes the placement of the orthodontic appliances on the patient's teeth. Method of designing such trays for indirect bonding orthodontic appliances are also included.

The present invention relates to an orthodontic height positioning gauge having bracket tabs to place a bracket, and lateral tabs configured to be placed along the occlusal surface of a lateral tooth. In such a position, the handle extends between the lateral jaw and the cheek, and the bracket located by the bracket tabs can be placed on the buccal surface of the tooth without hindrance due to the cheek.

A system and method that is a web based application for creating and managing orthodontic laboratory prescriptions within a dental clinic or lab. The system receives a standard triangle language (STL) image file which has been obtained from an intraoral digital scan or cone-beam of a patient's mouth and teeth. The user manually selects brackets, attachments, bands, or other appliances and removes them from the 3D image file via a series of selections made through an interface within a digital workspace. The system then calculates a surface of the tooth that was disposed beneath the removed appliance and integrates it into the 3D image to create a clean 3D image of the patient's teeth free from any appliances. After the appliances have been removed, the user may further refine the image of the patient's teeth using a suite of tools including addition, deletion, smoothening, and definition tools.

An orthodontic appliance may include an outer shell having a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance may also include an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.

A bracket system for orthodontic appliances including a bracket combinatorial library having a plurality of brackets each interchangeably fixedly mountable to each of a plurality of teeth within a dentition group in a dental arch, whereby the plurality of brackets can be configured to provide incremental variation in tipping force moments, in-out force moments, and torqueing force moments over the entire useful range of orthodontic mechanics, allowing an orthodontic practitioner to prescribe a combination of tipping force moments, in-out force moments, and torqueing force moments unique for each tooth in relation to the plurality of teeth of a patient.

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.
