Abstract: The present invention relates to a maxillary teeth orthodontic device capable of correcting upper jaw molars and anterior teeth by moving the upper jaw molars and the anterior teeth in forward and backward directions. The maxillary teeth orthodontic device comprises: a body attached to the bottom surface of the gums of the upper jaw; a connection leg of which one end is connected and extended from the body; a molar fixing part connected to the other end of the connection leg and fitted into a molar; and a ring part connected to one side of the lower surface of the body, wherein the body is divided into a first body and a second body such that gaps are adjusted by allowing the first body and the second body to be spaced from each other or approach each other in the incisor direction and the airway direction of the upper jaw.

Abstract: The present invention relates to a tool for adhering an orthodontic bracket, comprising: a pair of bracket holding portions for holding a bracket to be bonded to teeth while approaching or separating from each other; and a pair of handle portions connected to the pair of bracket holding portions, for controlling the bracket holding portions to allow the same to approach or separate from each other, wherein a scale for measuring the height of a bracket for the end of teeth is formed in at least any one of the pair of bracket holding portions. Therefore, an operation is convenient, measurement is easy and measurement time can be reduced since the tool has a simple and uncomplicated structure. In addition, it is possible to improve the effectiveness of orthodontic treatment since a bracket can be bonded by precisely setting the height of the bracket.

Abstract: The present invention relates to an apparatus for driving an anchor to support the orthodontic wire for correcting the twisted teeth by connecting a number of teeth in a body. The apparatus for driving an anchor comprises a fixed holding part which surrounds partly some space between a pair of two adjacent teeth and has a penetrated thread hole facing the side of the gum, a movable holding part which surrounds partly some space between a pair of two adjacent teeth by approaching to and getting away the fixed holding part and has a supporting protrusion which supports the side of protruding gum, an anchor position setting up part which determines the position at which the anchor is installed by being connected to at least one of the fixed holding part and the movable holding part, a adjusting screw which supports the side of the gum by being connected to the penetrated thread hole of the fixed holding part and adjusting the distance between the fixed holding part and the movable part.

Abstract: An apparatus for measuring jaw motion has a pair of fixed marker attached to both sides of face of patient, a pair of movable markers disposed to face the fixed marker in a spaced distance and to move in unison with the movement of the lower jaw of patient, four cameras recording the three-dimensional movement of the movable marker relative to the fixed marker, as lower jaw moves, and personal computer for receiving and processing the image signals fed from connected cameras. The apparatus can accurately measure the location of the center of patient's jaw motion and the moving track thereof with stereo vision processing of the image signals obtained from camera.

Abstract: An anchor implanting device for orthodontics used for implanting an wire supporting anchor supporting a teeth supporting wire which supports a plurality of teeth and correct the teeth, comprises a tooth supporter supportedly enclosing a portion between a pair of neighboring teeth elastically in a transverse direction relative to an array direction of the teeth; a locating projection projected inward in a radial direction from the tooth supporter and positioned between the pair of neighboring teeth and a gum; at least one anchor positioning unit extended from the tooth supporter, positioned on the side of the gum so as to establish an implanting position of the wire supporting anchor. With this configuration, the present invention provides an anchor implanting device for orthodontics, allowing a wire supporting anchor to be implanted on the predetermined position of the gum in an easy manner.

Abstract: An orthodontic jig for attaching orthodontic brackets on the teeth is disclosed. The orthodontic jig comprises a housing, a bracket support extending out of the front side of the housing through the back side of the housing, tweezers for gripping the tie wings of the bracket connected to the housing and disposed around the bracket support, a cusp tip reference means for setting the cusp tip of the tooth as the reference surface of the orthodontic position, means for displacing the cusp tip reference plate upward or downward, and a handle connected to the upper and lower surface of housing for supporting the housing. The orthodontic jig can be connected with a cusp tip reference means or/and a lingual bracket positioning device.
