Description

Balloon water pressure type tooth orthotic devices
Technical Field
The invention relates to a tooth correcting tool, in particular to a balloon hydraulic type tooth positioner.
Background
Orthodontic treatment is broadly defined and generally refers to the treatment of irregular tooth alignment, abnormal tooth morphology, and abnormal tooth color by oral techniques. The method is characterized in that a plurality of methods such as resin veneering, porcelain teeth, orthodontics and the like are adopted for tooth correction, treatment methods are selected according to the actual tooth conditions, the tooth jaw deformity types and the like of individuals and according to individual requirements, each method has advantages and disadvantages, different people have preferences, a scheme needs to be directly communicated with a doctor during examination, functional correction and aesthetic correction are mainly adopted, and compared with children, adults have more limitations when receiving comprehensive tooth correction treatment. The problem of occlusion of teeth is caused by dysplasia of the maxilla and mandible, since the face and bones of adults are substantially fixed and are treated radically by orthodontic treatment. Only by combining orthodontic and maxillofacial surgery, deviations in the development of the jaw bone in adults can be corrected. Functional orthotics used in correcting jaw structure in children are generally not successfully used in adults. More and more adults are seeking orthodontic treatment to improve their smile, correct occlusal conditions or correct other problems caused by bruising, illness or prolonged neglect of oral care, to improve confidence in a healthy, beautiful smile for any age. Healthy teeth can be moved at any age, many orthodontic problems of adults can be easily solved like children, and for sixties and twelve years old children, the force applied in orthodontic has the same effect on tooth movement, of course, because facial bones of adults do not grow, some serious malocclusions cannot be corrected by using an appliance alone, and sometimes maxillofacial surgery and matching with orthodontic teeth are needed to solve the problem.
However, the existing orthodontic devices generally perform the integral correction on all teeth in the oral cavity, the conditions of the teeth are different from one another, and the once-cut correction on the teeth generally causes pain and discomfort to the patient and even causes inflammatory reaction, thereby increasing the difficulty of the orthodontic treatment.
