Problems solved by technology

However, this method also has many shortcomings: ①It requires the close cooperation of the patient, and it is inconvenient to use; ②The removable appliance cannot be used with the fixed appliance at the same time, which reduces the efficiency of the treatment and prolongs the treatment time; ③The end of the attachment is small and sharp, Easy to irritate upper lip mucous membrane
However, the segmental arch technique also has disadvantages: ①It requires very cumbersome arch wire bending; ②The anchorage load is still borne by the dental arch, which is prone to loss of anchorage; ③The end of the arch wire is easy to irritate the upper lip mucosa, resulting in local trauma

Embodiment Construction

[0023] Such as Figure 1-Figure 4 As shown, the present embodiment includes the plastic palate support (1) of the Nance arch (1), the fixed lock groove block (2), the guide rod (3), and the traction device (4). Wherein, the fixed lock groove block is a flat structure (such as figure 2 ), embedded in the plastic palatal rest of Nai's arch, with a horizontal hole (5) and a screw hole (6) perpendicular to the hole in the center of the body, and flat flanks with holes (7) on both sides of the body ). Such as image 3 As shown, 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. The guide rod head (8) is flat, There is a screw hole (9) in the center, which is inserted 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 bloc...

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 includesa 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 embeddedcanine 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 ...
