Improved stationary type canine tooth distantly-moving device

Abstract

The invention relates to the technical field of orthodontic treatment, in particular to an improved stationary type canine tooth distantly-moving device. The improved stationary type canine tooth distantly-moving device comprises a cast linked crown of second premolars and first molar crowns of bilateral upper jaws, wherein the cast linked crown of second premolars and first molar crowns of the bilateral upper jaws is fixed on a tooth; a supporting groove corresponding to the tooth is welded in the centers of the jaw side of the linked crown; a supporting device is arranged between the bilateral cast linked crowns; a jaw side traction hook is arranged on the jaw side of the second premolars of the cast linked crown; and a palate side traction hook is arranged on the palate side of the second premolars of the cast linked crown. The improved stationary type canine tooth distantly-moving device provided by the invention can slightly draw lip side impacted canine to the position of the pulled first premolar at the initial stage of correction, also can avoid lip pendulum effect on upper anterior teeth caused by the fact that a nickel titanium arch wire is completely inserted into the groove at the early stage of correction as well as no beauty caused by a convex face, does not influence the alignment of other teeth due to the fact that the corresponding supporting grooves are welded on the second premolar and the first molar, and shortens the clinical correction time.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to an orthodontic device for distally moved impacted teeth, namely an improved fixed canine remote mover. Background technique [0002] One of the signs of the development of modern orthodontics is to achieve the goal of orthodontic treatment. The learning goals are balance, stability and aesthetics. wrong And impacted teeth have a serious impact on the health, appearance, function of the oral and maxillofacial system and the growth and development of the maxillofacial region. Ideally, during orthodontic treatment, only alveolar bone resorption and reconstruction do not occur, but studies have found that orthodontic treatment is closely related to the occurrence of tooth root resorption. When the root of the tooth is absorbed to a certain extent, the root of the tooth becomes shorter, which can cause the tooth to loosen and fall off, thereby affecting the function of the w...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that during the distal movement of the existing labial impacted canines, when the straight wire arch wire is fully inserted into the groove during the early correction, it will cause unnecessary lip inclination and molar inclination of the anterior teeth. Necessary movement, the use of invasive methods such as implant nails after the tooth extraction space is unnecessarily occupied will bring discomfort to the patient during use. The present invention provides an improved fixed canine remote mover, which can At the initial stage, the impacted canine can be quickly and lightly pulled to the position of the extracted first premolar, and it can also avoid the pendulum effect on the upper anterior teeth when the nickel-titanium arch wire is completely inserted into the groove in the early stage of orthodontic treatment. The lateral posterior teeth are fixed together with braces and act as anchorage, avoiding unnecessary forward movement of the posterior teeth
