Three-force-in-one movable appliance

Technical Field

The utility model relates to the field of orthodontics, concretely relates to ware is rescued in activity of three power unifications.

Background

The deciduous anterior teeth contra-occlusal deformity refers to a malocclusion deformity in which the lower jaw deciduous anterior teeth are located on the labial side of the upper jaw deciduous anterior teeth during occlusion and are in a repeated occlusal contra-coverage relationship, which is common clinically. The research of the Chinese dental medical society in 2000 shows that the morbidity of the deciduous teeth contradentate occlusion in China is 14.94 percent, and the morbidity is on the rise due to improper feeding mode and poor oral habits. When the deciduous teeth are reversely combined, because the lower jaw anterior deciduous teeth are positioned on the labial side of the upper jaw anterior deciduous teeth, the development of upper jaw bones and upper dental arches is limited, the upper jaw bones are insufficiently developed, the middle part of the face is sunken, and the beauty of the face is influenced; in addition, due to abnormal occlusion relation, the anterior teeth have poor food cutting capability and low chewing efficiency, and gastrointestinal diseases such as dyspepsia and the like are easily caused, so that the growth and development of children patients are influenced; furthermore, the front teeth are engaged in the opposite direction to disturb the pronunciation, singing, etc. of the infant, which makes the infant self-inferior and timid and affects the psychological health. If the abnormal condition is not corrected in time, the abnormal condition will be gradually aggravated along with the growth and development of the children patients. The purpose of the early blocking treatment of the retroarticular anterior teeth is to provide a favorable environment for the normal development of the upper and lower jawbones, reestablish the normal muscle balance of the maxillofacial region and avoid causing psychological influence on patients.

The optimal time for correcting the contra-occlusal case is the deciduous period, so that the correction time can be shortened, the correction difficulty is reduced, and a higher aesthetic positive side appearance is obtained. Because the age of 4-7 is the second rapid stage of craniomaxillary facial development and is the best time for correcting malocclusion deformity, the maxillary development limiting factor is removed at the moment, so that the growth and development of the sick children tend to be normal, and a better face type is obtained. In addition, research shows that after the deciduous teeth reverse occlusion treatment, the maxilla and the deciduous incisors move forwards, and the inherited permanent tooth germ also correspondingly moves forwards and downwards, so that the clinical significance for preventing the reverse occlusion from reappearing in the permanent tooth period is achieved.

The method for correcting the front teeth and the back teeth in the deciduous period mainly comprises an upper jaw occlusal pad type hyperbolic reed movable corrector, a lower jaw inclined plane guide plate corrector, a guide bow type movable corrector, an FR-III functional corrector, a face frame front tractor and the like. Most of the devices rely on single force, such as an upper jaw occlusal pad type hyperbolic reed movable appliance, a lower jaw inclined plane guide plate appliance and a guide bow type movable appliance, so that the time for relieving the inverse occlusal syndrome is short, but the frequency of the repeated diagnosis is high, and the facial form is not obviously improved; the main power device of the upper jaw occlusion cushion type hyperbolic reed movable appliance is a hyperbolic reed, acts on upper anterior teeth, does not generate direct acting force on lower jaw and lower anterior teeth, is only suitable for odontogenic and functional deciduous teeth and has poor effect on patients with bony anterior teeth and inverse occlusions; the bow-guiding type movable appliance is a device combining mechanical force and functional correcting force, can shorten correcting time, but has more limited adaptation diseases, is not applicable to all inverse occlusions, and is difficult to bend and positioned at the front part of the oral cavity of a patient to influence the beauty and the eating; the FR-III functional appliance can improve the facial form of patients with functional and mild osteoid contra-occlusions, but the FR-III functional appliance has larger volume, prevents the children from speaking after being worn, and is required to be worn for at least more than 12 hours every day, if the children cannot be actively matched, the treatment fails; although the face frame front traction device can improve the face shape, the early-stage front traction can generate more skeletal changes in a shorter time to promote the development of the maxilla, and the mandible slightly rotates downwards and backwards to improve the face shape, the face frame front traction device is more complex, the correcting force is larger, and the face frame front traction device is not easy to accept by a child patient and a parent.

The growth and development of human bodies and jaws are fast in the period of children or teenagers, the normal growth and development conforming to the jaws must be considered when the appliance is designed, the time for wearing the appliance is shortened as much as possible, and the influence on the growth and development of collar bones due to improper correction effect is prevented.
