Description

Impacted tooth three-dimensional control traction device

Technical Field

The utility model relates to the technical field of orthodontic appliances, in particular to a impacted tooth three-dimensional control traction device.

Background

At present, impacted teeth are the most common type of malocclusion in clinic, occur in any part of the upper and lower dental arches, and can be singly or frequently sent. Except for the third molar, the good teething positions comprise maxillary canine teeth, maxillary middle incisors, mandibular and maxillary second premolar teeth, mandibular canine teeth, maxillary lateral incisors and the like. The age is 8-12 years, the incidence rate is generally between 1% and 2%, and the proportion of orthodontic patients is 7.39%. Wherein, the proportion of the maxillary canine buried occlusion in the oral outpatient is 1 to 3 percent.

The impacted teeth are easy to cause the displacement of adjacent teeth or the absorption of tooth roots, which has adverse effect on the integrity of dentition, leads to the disorder of occlusion relation of front and back teeth, further influences the normal development and the beautiful appearance of jaw bones, and serious patients can cause the abnormal development of the left and right temporomandibular joints and influence the health of the temporomandibular joints.

The clinical treatment is to the permanent tooth that causes the permanent tooth to bury because of deciduous teeth are detained, the root of deciduous tooth absorbs inadequately and hinders the life, and the patient is less old, and the permanent tooth position is normal and still have the potential of erupting, can pull out deciduous tooth and make the permanent tooth erupt naturally. If the permanent tooth is buried and stopped growing due to multiple raw teeth, dental tumors and the like, the multiple raw teeth or the dental tumors should be removed as soon as possible to remove the barriers of the eruption path, so that the permanent tooth erupts automatically. Whether or not permanent teeth are exposed when many raw teeth are extracted, orthodontic traction, and the like may be performed at the same time, depending on the circumstances. For the buried impacted tooth caused by insufficient clearance, the permanent tooth still has the potential of eruption, and the orthodontic appliance can be used for expanding the clearance in the early stage according to the condition to observe the eruption condition of the impacted tooth. At present, the buried impacted tooth is treated clinically mainly through surgical windowing guided sprouting combined with orthodontic traction.

Clinically, the traction impacted tooth mainly has the following defects: the traditional orthodontic device is complex, more specific devices need to be placed on the arch wire, the traction direction is single, the tooth growth direction is variable, and three-dimensional angle traction is difficult to realize;
