The invention refers to medicine, namely orthodontic dentistry, and is intended for the treatment of dentofacial abnormalities for mass outpatient reception in dental rooms. The patient is examined using X-ray diagnostic measures: orthopantomography (OPTG), teleroentgenography (TRG), computer tomography (CT); the choice of a treatment strategy depends on the orthodontic pathology. The number of braces is determined taking into account the size of the slot and the shape of the orthodontic arc. After that, braces are pre-fixed on dental rows of the patient followed by the installation of the orthodontic arc. In this case, the arc originally installed in the brace slot is four-sided, the arc can have both square and rectangular section depending on the analysis of OPTG, TRG, and CT. An obligatory condition for installation of the four-sided arc at the beginning of orthodontic treatment is associated with compliance with the specified arc load exerted on the moving teeth.

An orthodontic correction device is provided, including a shell having a number of teeth receiving cavities configured to receive teeth of a dental arch of a patient. A first elastic member holding feature is formed on one side of the shell and corresponds to an undercut region of a tooth of the dental arch. A first orthodontic elastic member is coupled to the first elastic member holding feature and extends to the interior of the shell to engage with the undercut region of the tooth, thereby enhancing the retention of the orthodontic correction device on the dental arch.

An orthodontic space closure device is provided, including a first tooth cap unit, a second tooth cap unit, and a number of elastic members. The first tooth cap unit is configured to be removably worn on the anterior teeth of a dental arch of a patient. At least one first connector is fixed on each buccal side of the first tooth cap unit. The second tooth cap unit is configured to be removably worn on the posterior teeth of the dental arch. A vertical extension part is formed on each buccal side of the second tooth cap unit, and at least one second connector is fixed on each vertical extension part. The elastic members couple the first connectors to the second connectors, thereby exerting elastic traction forces having horizontal and vertical components on the first tooth cap unit to achieve retraction and intrusion of the anterior teeth.

The present invention is a cosmetic dental insert that combines vacuum-formed retainers with orthodontic braces to produce a cosmetically appealing appearance of braces along translucent vacuum-formed retainers. The cosmetic dental insert contains a first dental fitment, a second dental fitment, a first set of braces, and a second set of braces. The first dental fitment and the second dental fitment each comprises a fitment body, a teeth receiving channel, and a mounting surface. The mounting surface is positioned external to the fitment body. The teeth receiving channel traverses into and along the fitment body. The first set of braces traverses along the mounting surface of the first dental fitment. The second set of braces traverses along the mounting surface of the second dental fitment.

Disclosed are devices, systems and methods for monitoring usage of an elastic component of an orthodontic article. In some aspects, an apparatus for monitoring elastics usage with an orthodontic article includes a sensor to detect a physical parameter associated with an elastic component when the elastic component is coupled to the orthodontic article, wherein the sensor is attachable to the orthodontic article or to the elastic article and operable to transduce the detected physical parameter into an electrical signal; a data processing unit, comprising a processor and a memory, in communication with the sensor to receive the electrical signal from the sensor and to process the electrical signal as data to be stored or transmitted by the apparatus; and a power source to supply power to the sensor and to the data processing unit.

An orthodontic bracket is provided, including a backend surface, a frontend surface, a first side surface, a second side surface, and a passageway. The backend surface is adapted for attachment and is opposite the frontend surface. The first and second side surfaces are connected between the backend surface and the frontend surface. The passageway extends from the first side surface to the second side surface. The cross-section of the passageway includes an access opening, an archwire slot, a path portion, and at least one rotation portion. The access opening is configured to allow the archwire to enter the passageway. The archwire slot is configured to receive the archwire. The path portion connects the access opening and the archwire slot. The rotation portion is provided in the path portion to allow the archwire to change its orientation.

An orthodontic bracket is provided, including a main body, a cover, and an elastic spring element. The main body has an archwire slot configured to receive an archwire. The cover is hingedly connected to the main body, and the cover can be moved between an open position and a closed position. The open position exposes the archwire slot and the closed position covers the archwire slot. The elastic spring element is disposed in the main body, coupled to the cover and the main body, and configured to generate a force that moves the cover into the open position.

Self-activated orthodontic expander including a left frame and a right frame, where the left frame and right frame include, respectively, a left body and a right body, each having anchoring element for anchoring them to the teeth of a dental arch. The bodies have through holes oriented in a predetermined expansion direction, where the frames are slidably mounted along the expansion direction by guides inserted into the holes of the bodies. Elastic elements are arranged and acting between the frames. The guides are further constrained with each other by a bridge oriented orthogonally to the same guides and adapted to prevent the reciprocal movement of the guides.

A self-ligating bracket system comprising a body, an archwire slot receivable for an archwire, and a locking mechanism, the locking mechanism configured to allow a ligating sliding member to move between an open position, such that an archwire may be inserted into and/or removed from the archwire slot, and a closed position, such that an archwire is retained within the archwire slot.

Disclosed is an orthodontic bracket including a bracket body having a slot into which an orthodontic wire is inserted, a bracket cover mounted on the bracket body and configured to open and close the slot, and a ligating member provided in the bracket cover and configured to selectively block the slot so as to confine the orthodontic wire in the slot. The orthodontic bracket may precisely and consistently transmit force, for example, torque, of the orthodontic wire to a tooth, and minimize or prevent factors contributing to failure, such as deformation of or damage to the ligating member due to opening and closing of the slot.
