TL;DR: A maxillary skeletal expander is composed of a pair of dental arch expansion bodies positioned to face each other in an oral cavity; an expanding screw provided between the pair of DAs to move the DAs without deviation; a DAs expansion body combining means having a fixing piece for penetrating a fixing hole at a selected part in the oral cavity as discussed by the authors.
Abstract: A maxillary skeletal expander is proposed. The maxillary skeletal expander is composed of a pair of dental arch expansion bodies positioned to face each other in an oral cavity; an expanding screw provided between the pair of dental arch expansion bodies to move the dental arch expansion bodies; a guide provided between the pair of dental arch expansion bodies to safely move the dental arch expansion bodies without deviation; a dental arch expansion body combining means having a fixing piece for penetrating a fixing hole at a selected part in the oral cavity, and configured to be combined to and separated from each of the dental arch expansion bodies.

TL;DR: An orthodontics bracket as discussed by the authors is a bracket that includes a base portion attached to the tooth surface, a slot(120) which is prepared at the center of base portion and into which the steel wire is inserted, first and second wings(140a,140b) which are projected from the base portion while leaving a distance, a connection hole(150) which was formed in the second wing; a connection rod(160) which fitted into the connection hole; and a slot cover(170) which has a connection ring which is hung on the connection rod.
Abstract: PURPOSE: An orthodontics bracket is provided, which is easy to fix and separate the steel wire for the orthodontic treatment and is capable of enhancing the orthodontic force continuously. CONSTITUTION: An orthodontics bracket includes: a base portion(110) which is attached to the tooth surface; a slot(120) which is prepared at the center of base portion and into which the steel wire is inserted; first and second wings(140a,140b) which are projected from the base portion while leaving a distance; a connection hole(150) which is formed in the second wing; a connection rod(160) which is fitted into the connection hole; and a slot cover(170) which has a connection ring which is hung on the connection rod. The connection ring bends one end part of the slot cover in a polygonal shape.

TL;DR: In this paper, a hybrid orthodontic device is presented, which consists of an extending unit disposed in an oral cavity between teeth disposed to be opposed to each other, and including a plurality of extension pieces coupled with each other through a screw type to apply extension power to the side of the teeth.
Abstract: According to the present invention, disclosed is a hybrid orthodontic device. The hybrid orthodontic device can ensure a rapid orthodontic procedure by simultaneously ensuring teeth set enlargement and teeth set centrifugal movement for non-extraction orthodontic treatment. The hybrid orthodontic device is installed between teeth to be extended, and applies extension power to the side of the teeth. The hybrid orthodontic device comprises: an extending unit disposed in an oral cavity between teeth disposed to be opposed to each other, and including a plurality of extension pieces coupled with each other through a screw type to apply extension power to the side of the teeth; a teeth coupling unit inserted in the outer surface of the teeth to which the extension power is to applied, including a plurality of bands coupled with the teeth, and including a plurality of wires, each of which has one end fixed to the extending unit and the other end fixed to one side of each of the bands and disposed in a radial direction; and a towing unit for towing the extending unit to the core of the teeth. The hybrid orthodontic device is installed between teeth disposed to be opposed to each other, and can ensure a space by extending a distance between teeth even without extracting a tooth by applying extension power to the side of the teeth. Also, towing power is generated in a core direction of a teeth set, so the teeth are towed to the core side of the teeth set. Thus, a space is ensured between an anterior tooth and a molar. Accordingly, orthodontic treatment can be effectively performed.

TL;DR: In this article, a maxillary expansion device having a triple screw system for rapid palatal expansion is presented. But the system is laterally asymmetric and the size of the expansion screw required to obtain a desired amount of expansion can be hardly positioned.
Abstract: The present invention relates to a maxillary expansion device having a triple screw system for rapid palatal expansion. In the case of narrow and constricted maxillary arches requiring rapid palatal expansion, an expansion screw that is large enough to obtain a desired amount of expansion can be hardly positioned and new device preparation and repetition of procedures are required for additional expansion. The present invention is to deal with an increase in cost and hassles attributable to those requirements and allow adjustment of the amount of palatal expansion that is laterally asymmetrical. The present invention includes: a pair of left main bodies; a pair of right main bodies; a first expansion screw having both side portions inserted to penetrate the left main bodies and the right main bodies and adjusting a gap between the left main bodies and the right main bodies; a second expansion screw having both side portions inserted to penetrate the left main bodies and adjusting a gap between the left main bodies; and a third expansion screw having both side portions inserted to penetrate the right main bodies and adjusting a gap between the right main bodies.

TL;DR: In this article, an orthodontic appliance that is fixed to a part of the mouth and corrects teeth is described, where a device body is installed in a direction perpendicular to the tongue in the central portion of the roof of a mouth.
Abstract: The present invention relates to an orthodontic appliance that is fixed to a part of the mouth and corrects teeth, wherein the orthodontic appliance comprises: a device body installed in a direction perpendicular to the tongue in the central portion of the roof of the mouth; a separation unit that forms the body of the device body and extends in the longitudinal direction by pressurization of an external force to open the roof; and a fixing unit that is provided on a part of the separation unit and provides fixing force for opening the roof according to the separation of the separation unit by fixing the device body to the roof.

TL;DR: In this article, a dental arch extension system with a loosening prevention function was proposed to prevent a screw from being loosened after surgery, where a pair of guide rods were used to adjust an interval between the first and second extension parts while being rotated.
Abstract: The present invention relates to a dental arch extension apparatus and, more specifically, to a dental arch extension apparatus with a loosening prevention function of preventing a screw from being loosened after surgery. According to the present invention, the dental arch extension apparatus comprises: a pair of first and second extension parts; an extension screw having a central part and having a first screw part formed on one side of the central part to be screw-coupled to the first extension part and a second screw part formed on the other side of the central part to be screw-coupled to the second extension part so as to adjust an interval between the first and second extension parts while being rotated; a pair of guide rods guiding movement of the first and second extension parts when the first and second extension parts are moved by rotation of the extension screw; and a loosening prevention member restricting the rotation of the extension screw by the stress within elastic limit.

TL;DR: In this article, an upper jaw orthodontic apparatus was proposed to correct the location of the teeth on both sides of the upper jaw by adjusting the angle of a band when inserting the band into the teeth.
Abstract: The present invention relates to an upper jaw orthodontic apparatus which corrects the location of the teeth on both sides of the upper jaw, and to an orthodontics method using the same. A user can easily mount the upper jaw orthodontic apparatus on the teeth by adjusting the angle of a band of the orthodontic apparatus when inserting the band into the teeth. The upper jaw orthodontic apparatus comprises: a support body connected to a support bar to be separated from the band at a fixed distance to reinforce the strength between the band and the support bar; a mesh member arranged between the support body and the band; and an angle adjusting means composed of a reinforcing member applied and cured on the angle adjusting means while surrounding the mesh member.
