Description

Molar extension and remote movement device for correction Technical Field The utility model relates to the field of medical appliances, in particular to a molar extension device for correction. Background The invisible appliance is more and more favored by dental patients due to the characteristics of attractive appearance, comfort and the like, and is an important means for orthodontic treatment at present, however, the invisible appliance has defects in adjusting and correcting the molar in the vertical direction, and related data show that the insufficient molar elongation is a common cause of invisible correction failure cases because the invisible appliance is difficult to establish an effective vertical anchorage system. And in order to improve the facial aspect and relieve crowding of teeth, it is often necessary to move the molars distally. The reaction force of the invisible tooth socket during pushing and grinding is used for weakening the efficiency of pushing and grinding teeth, and sometimes even the incisor root is subjected to bone windowing. In order to solve the above problems, there is a need for an apparatus for additionally performing extension movement of the molars, but in the current apparatus (CN 2023115908047), the force bearing point of the extension molars comes from the adjacent molars, which may have adverse effects on the adjacent molars, especially when the adjacent molars also need extension movement correction, the current apparatus looks at the front to see the elbow, and in addition, the apparatus can perform correction treatment on only a single molars at a time, if a plurality of molars all need extension movement, the correction needs to be performed in batches, which increases the correction time and wastes time and labor. Disclosure of utility model The utility model aims to provide a molar extension device for correction so as to solve the problems in the background technology. In order to solve the technical problems, the utility model provides the following technical scheme: The molar extension device for correction comprises a molar extension device for correction and is characterized by comprising a pair of fixing blocks which are used for being fixed on the outer side walls of adjacent molar teeth, wherein the side walls of the two fixing blocks facing to dental beds are connected with elastic components together, and the tail ends of the elastic components are used for fixing the elastic components on the dental beds. In a further embodiment, the elastic component is a section of continuous bending metal wire, the metal wire is divided into two sides, each side of the metal wire comprises a fixed block connecting section connected to the side wall of the fixed block, the other end of the fixed block connecting section is connected with an elastic bending section, the other end of the elastic bending section is connected with a gum connecting section, and one ends of the gum connecting sections on the two sides are connected with a lantern ring together. In a further embodiment, each side of the connecting section of the fixing block, the elastic bending section and the gum connecting section form an inclined omega shape, the connecting sections of the fixing blocks on two sides are inclined towards the inside of the oral cavity and the inclined direction away from other teeth at the same time, and the elastic bending section is in circular arc expansion bending towards the outer side direction of the metal wire. In a further embodiment, the elastic component is provided with a gum fixing nail at the end, and a groove for clamping the fixing collar is arranged on the gum fixing nail. Preferably, the fixing block, the metal wire and the gum fixing nail are all made of stainless steel. Compared with the prior art, the utility model has the beneficial effects that: The stress pivot of the extended and remote molar is adjusted to the position of the gum without affecting adjacent molar, and the utility model can adjust two molar at a time, and can greatly shorten the correction time and improve the correction efficiency when being used together with the invisible appliance.
