Embodiment Construction

[0023] As shown in Figures 1-4, this embodiment includes a Nance arch plastic palate support (1), a fixed locking groove block (2), a guide rod (3), and a traction device (4). Among them, the fixed lock groove block is a flat structure (as shown in Figure 2), which is embedded in the plastic palate of the Nai's arch. The center of its body has a horizontal hole (5) and a screw hole (6) perpendicular to the hole. ), the two sides of the body are flat flanks with holes (7). As shown in Figure 3, the guide rod (3) is an elastic steel body with a certain rigidity and can be bent to a certain extent, so as to adapt to the shape of the maxillary alveolar ridge and adjust the direction in three-dimensional space, and the guide rod head (8) is Flat, with a screw hole (9) in the center, plugged into the horizontal channel (5) of the fixed lock groove block, and the screw (10) forms a detachable fixed connection with the fixed lock groove block through the screw hole; the end of the gui...

Abstract

The present invention relates to oral orthodontic technology, and is especially one kind of guide rod type orthodontic appliance for upper jaw embedded canine teeth. The orthodontic appliance includes a plastic palatal arch support, a fixing block, a guide rod, and an extraction device. The present invention aims at providing one kind of guide rod type orthodontic appliance for upper jaw embedded canine teeth with 3D adjustable orthodontic force, no use of dentition as anchorage and less irritation on upper lip mucous membrane. The present invention has the advantages of small orthodontic force, less blocking interference of adjacent teeth, reduced teeth moving resistance, less irritation on mucous membrane, etc.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a guide rod type appliance for correcting maxillary embedded canines. Background technique [0002] Maxillary impacted teeth are common dental and jaw deformities, and the highest incidence rate is maxillary horizontal impacted canines and inverted impacted central incisors. These dental deformities will seriously affect facial appearance and masticatory function. [0003] Maxillary impacted teeth, especially in complex cases, are difficult to correct. The main reasons are: ①The crown of the impacted tooth is in a strange position in three-dimensional space, and it overlaps with the adjacent tooth root; ②The buccolingual The diameter of the impacted teeth is narrow, and the impacted teeth are limited to the narrow alveolar bone; ③The crown moves a large distance during the treatment, and the treatment time is long; ④Complicated treatment techniques and arch wire bending are ...
