Description

Correction device for depressing anterior teeth

Technical Field

The utility model relates to the technical field of orthodontics, in particular to a correcting device for depressing anterior teeth.

Background

Along with more and more attention paid to the attractiveness of teeth, the research on the tooth fixing and correcting technology is gradually deepened, and different correcting methods are adopted for different malocclusion deformities. Deep covering of the jaw is one of the deformities of the jaw, and is particularly an abnormality of the vertical relationship of the upper and lower jaw arches. The incisor margin of the upper anterior tooth covers the length 1/3 of the crown of the lower anterior tooth or the lower anterior tooth is occluded above the lingual side 1/3 of the upper anterior tooth, which is mainly characterized by over-short of the lower surface 1/3 and limited movement of the lower jaw, thus greatly affecting the beauty and chewing function. The deep jaw is formed because the anterior alveolar bone or the jaw bone is too high and the posterior alveolar bone or the jaw bone is not high enough.

For the correction of deep covering jaw, on one hand, the micro-implant anchorage nail can be clinically used for assisting in treating and depressing anterior teeth, but the existing anchorage nail needs surgical implantation, is expensive, needs frequent stress application, and has the possibility of increasing the frequency of repeated diagnosis, foreign body sensation and mucosal infection. On the other hand, the fixed appliance is matched with the jaw pad to be lifted, and the square wire arch and the thin wire arch appliance are used for opening the occlusion of the anterior teeth; the existing arch wires which are opened and occluded and are commonly used in the orthodontic field are a rocking chair arch and a multipurpose lip arch, are used as orthodontic main arch wires and are used for pressing down anterior teeth. As the main arch wires are all required to be put into the bracket grooves, the force for pressing the anterior teeth to open the occlusion is uniformly dispersed in the tooth bracket grooves, the force acting on the anterior teeth is limited, and the effect is limited. There is therefore a need for a non-invasive, simple, easy to operate, low cost device that overcomes the disadvantages of the prior art.

The utility model discloses an orthodontic device for depressing anterior teeth, which comprises the following components by referring to fig. 1: a primary archwire 10, a secondary archwire 20, and a number of brackets 30. Brackets 30 are bonded to lingual surfaces, and specifically, one bracket 30 is bonded to each tooth 40 of the appliance. The main arch wire 10 is fixed on the bracket 30 and plays a basic role in correction; the auxiliary arch wire 20 is positioned in the lingual direction of the main arch wire 10, the end of the auxiliary arch wire 20 is fixed to the brackets 30 in the bicuspid and molar zones, and the position of the auxiliary arch wire 20 relative to the midline of the anterior zone (i.e., the central portion of the auxiliary arch wire 20) is fixed to the corresponding position of the main arch wire 10. The size, thickness and radian of the auxiliary arch wire 20 can be designed according to the correction requirement, so that when the auxiliary arch wire 20 is connected to the main arch wire 10, the elastic deformation of the auxiliary arch wire 20 resets the acting force applied to the main arch wire 10 and faces to the gum direction.

Through setting up supplementary arch wire 20, supplementary arch wire 20 is fixed in on the anterior teeth district central line position of main arch wire 10, and the elastic deformation of supplementary arch wire 20 applys the effort in the gum direction for main arch wire 10, has strengthened the control force that main arch wire 10 acted on the anterior tooth, and the effect of holding down the anterior tooth is good, makes the back tooth have enough space simultaneously and risees, effectively improves and covers the jaw symptom deeply. The utility model does not need to be nailed, has simple and convenient operation and easy use, is positioned in the lingual direction and is invisible and beautiful.

Preferably, a lower hook-shaped lowering hook 21 is disposed on the auxiliary arch wire 20 at a position corresponding to the midline of the anterior dental area, the lowering hook 21 is fastened to the main arch wire 10, and the opening direction of the lowering hook 21 faces the gum direction. The matching mode can realize quick buckling or disassembling of the auxiliary arch wire 20 and the main arch wire 10 while ensuring that the auxiliary arch wire can continuously apply control force to the main arch wire, is simple to operate and saves the treatment time of doctors.

To facilitate installation of the auxiliary archwire 20, the brackets 30 in the bicuspid and molar zones preferably include: a main groove 31 and an auxiliary fixing portion; the main arch wire 10 is penetrated and fixed in the main groove 31, the auxiliary arch wire 20 is fixed on the auxiliary fixing part, thus, the main arch wire 10 and the auxiliary arch wire 20 are both arranged and connected in the bracket 30, the structure is simple, and the number of accessories is small. Further preferably, the auxiliary fixing part is a circular tube structure 32, and the end of the auxiliary arch wire 20 is inserted into the circular tube structure 32; the circular tube structure 32 can be used for quickly inserting or extracting the auxiliary arch wire 20, and the operation is convenient and time-saving. Of course, the tubular structure 32 is not the only mounting structure, and other connecting means known in the art, such as snap, screw, etc., should be considered within the scope of the present invention.
