Bilateral molar pushing oral appliance

Abstract

The invention discloses a bilateral molars pushing oral appliance which is characterized by comprising a base, a base plate, a first molars, a third molars, a belt ring, a palate side stress application bent spring, a premolars support wire and a cheek side stress application bent spring, according to the double-side molar pushing oral appliance designed by the invention, the stress is balanced and stable in the molar far-moving process, the joint of the extension section of the cheek side stress application bent spring and the premolar supporting wire is integrally formed, food residues are not easy to remain and easy to clean, and the food residues are prevented from breeding bacteria in the oral cavity; 1 / 2 of the belt ring is additionally arranged on the third molar, so that the acting force of the whole appliance is more stable.

Description

technical field [0001] The invention belongs to the field of oral orthodontic appliances, in particular to a bilateral molar pushing oral appliance. Background technique [0002] Orthodontics is an operation to treat malocclusion through orthodontics or surgery. During the process of orthodontic treatment, unless there is not enough space for orthodontic treatment and necessary extraction, doctors generally try to retain normal and healthy teeth as much as possible and complete non-extraction orthodontic treatment. Bilateral molar advancement is a method of orthodontic treatment. Moving the molars to the distal position, increasing the length of the dental arch and providing space is one of the methods of non-extraction orthodontic treatment; [0003] Pendulum appliance is a common method for moving maxillary molars distally in orthodontics. It uses soft and hard tissues in the mouth as anchorages to move molars distally, avoiding the discomfort and inconvenience caused by e...

Problems solved by technology

[0003] Pendulum appliance is a common method for orthodontics to move maxillary molars distally. It uses the soft and hard tissues in the mouth as anchorage to move molars distally, avoiding the discomfort and inconvenience brought by extraoral anchorage to patients, and is very popular in orthodontics. Favored by doctors; the currently used pendulum appliance has the following disadvantages: 1) The force spring of the current pendulum appliance is only set on the palatal side, and the correction force is applied unevenly, and the teeth are easy to deviate to the palatal side; 2) Some appliances also add curved springs on the buccal side to balance the force on the palatal side, but the premolar wires and the buccal curved springs are independent of each other, and the gap between them is easy to leave food residues, which is not conducive to cleaning. The environment in the oral cavity is easy to breed bacteria; 3) Using the existing pendulum appliance, no matter whether there are palatal and buccal curved springs acting in the oral cavity for a long time, the correction force is prone to shift and the force is unstable
