Embodiment

[0039] Taking the lower impacted tooth on the labial side as an example, the specific usage method of the three-dimensional control traction device for the impacted tooth in this embodiment is illustrated:

[0040] 1. Adhesive tongue buckle

[0041] Surgical exposure of the labial crown of the impacted tooth, bonding tongue buckle 31;

[0042] 2. Glue the trailing arm

[0043] Before the patient's surgical window is opened, the model is made, the anchorage device 1 is made, the image data is taken to estimate the eruption position of the labial side of the impacted tooth, the traction arm 2 is bent, the two are firmly connected, and the device is bonded after the window is opened; And place a rubber chain or an elastic line between the tongue button 31 and the second end of the traction member 23 for traction;

[0044] 3. Follow-up visits will be strengthened

[0045] After the traction arm 2 is installed, the elastic wire and the rubber chain exert continuous and gentle tr...

Abstract

The invention discloses an impacted tooth three-dimensional control traction device, and relates to the technical field of orthodontic instruments, the impacted tooth three-dimensional control traction device is characterized in that an anchorage device is mounted on a to-be-used occlusal surface, and the anchorage device is connected with a to-be-used labial surface through a traction arm; molar casting belts are installed on the two sides of the base through supporting bows, the traction arm is installed on the base, the molar casting belts are installed on first molars or second molars on the two sides of the upper jaw of a to-be-used occlusal face, and the base is installed on the hard palate portion of the anterior tooth area of the to-be-used occlusal face. A fixing piece first end is further installed on the base plate, a turning ring is wound around a fixing piece second end, and a traction piece first end is connected to the outer side of the turning ring; the second end of the traction piece is installed on the lip face to be used through the tongue traction piece. The impacted tooth traction device can simultaneously perform traction on a plurality of impacted teeth without mutual influence, and the device is simple in preparation method and convenient for clinical operation.

Description

technical field [0001] The invention relates to the technical field of orthodontic appliances, in particular to a three-dimensional control traction device for impacted teeth. Background technique [0002] At present, impacted teeth are a relatively common clinical malocclusion type, which can occur in any part of the upper and lower dental arches, and can be single or multiple. In addition to the third molars, the most frequent teeth were maxillary canines, maxillary central incisors, mandibular and maxillary second premolars, mandibular canines, maxillary lateral incisors, etc. The age of discovery is mostly 8-12 years old, the incidence rate is generally between 1% and 2%, and the proportion of orthodontic patients is 7.39%. Among them, impacted maxillary canines accounted for 1%-3% of outpatients. [0003] Impacted teeth are likely to cause displacement of adjacent teeth or root absorption, which will have a negative impact on the integrity of the dentition, resulting ...
