Description
Technical Field
The utility model belongs to the field of medical equipment, more specifically relates to an orthodontic butterfly shape cross palate bar.
Background
According to the law of acting force on reaction force, when orthodontic treatment is carried out, the orthodontic force is generated, and simultaneously, reaction force with equal magnitude and opposite direction is necessarily generated. Orthodontists often need to manage to counteract the reaction forces caused by the orthodontic forces, and the situation in which such reactions caused by moving orthodontic teeth are supported is called "anchorage". A common strategy for anchorage control is to concentrate the forces on the area where the teeth are expected to move, and to distribute the reaction forces as much as possible on other teeth, on the palate, on the head and neck or on the implant in the jaw, ensuring that the periodontal membrane of the anchorage tooth is subjected to as little pressure as possible.
A trans-palatal bar (TPA), a commonly used orthodontic appliance for increasing anchorage, is attached to the first bilateral molars of the upper jaw, spans the upper palate, and increases the molar anchorage by releasing a portion of the reaction force when moving the teeth to the palate. Compared with the situation that the extraoral arch is difficult to wear all day long and the force application is too large, and the invasive implantation nail operation risk, the cross palatal bar has the characteristics of simple use and no dependence on the cooperation of patients. The conventional TPA can prevent elongation of molars and maintain the width between molars, but when the depression of the second molar of the upper jaw needs to be realized, an implant anchorage needs to be implanted at the buccal side and the palatal side, which not only increases the treatment risk, but also brings pain to the patient.
Therefore, it is expected to develop a butterfly-shaped lateral palate bar for orthodontic treatment, which can reduce the use of implanted nail anchorage, and has good retention, safety and reliability.
