Description
Technical Field
The utility model relates to the field of orthodontic appliances for teeth, in particular to a molar advancing device.
Background
The molar loss is common in clinic, the traditional restoration treatment and the existing implantation operation treatment means can solve the requirements of patients, but can hurt the original teeth of the patients and cause operation trauma, the treatment cost is high, and the treatment is not long-lasting. With the development of orthodontic treatment technology, patients can choose to replace the missing first molar by the advancing of the second and third molars on the same side of traction. Most structures of the existing molar advancing device are complex, or the whole teeth or half teeth are required to be corrected through correction, the complex structure can cause high manufacturing cost, the operation difficulty of medical staff can be increased, meanwhile, the patient experience is poor, and the treatment cost of the patient can be further increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the prior art is not enough to overcome, and a molar advancing device with simple structure, low cost, convenient operation and good use effect is provided.
The utility model adopts the technical proposal that: the utility model discloses an anchorage nail, setting are in bracing piece, setting on the anchorage nail are in guide arm and slip on the bracing piece set up buccal surface pipe on the guide arm, be provided with the hook on the buccal surface pipe, buccal surface pipe is located the rear end of guide arm, molar antedisplacement device includes the elastic webbing, the one end setting of elastic webbing is in on the hook, the other end setting of elastic webbing is in the front end of guide arm.
Furthermore, the elastic belt is an elastic chain, a plurality of adjusting holes are formed in the elastic chain along the length of the elastic chain, and one adjusting hole is hooked on the hook; different adjusting holes are hooked on the hook, so that the tension of the elastic chain on the buccal tube can be adjusted.
Furthermore, the support rod and the guide rod are designed integrally, the connecting part of the support rod and the guide rod protrudes backwards to form a convex part, and the end part of the elastic belt is hung on the convex part.
Furthermore, the support rod and the guide rod are formed by bending stainless steel orthodontic wires into a whole, and the convex part is also formed by bending the stainless steel orthodontic wires.
The utility model has the advantages that: because the utility model discloses an anchorage nail, setting are in bracing piece, setting on the anchorage nail are in guide arm and slip on the bracing piece set up buccal surface pipe on the guide arm, be provided with the hook on the buccal surface pipe, buccal surface pipe is located the rear end of guide arm, molar antedisplacement device includes the elastic webbing, the one end setting of elastic webbing is in on the hook, the other end setting of elastic webbing is in the front end of guide arm. Therefore, the utility model has simple structure and low cost, can adjust the orthodontic force of the teeth through the tightness of the elastic band in the using process, and has convenient operation and good using effect.

Detailed Description
As shown in fig. 1, in this embodiment, the utility model discloses an anchorage nail 1, setting are in bracing piece 2, the setting on the anchorage nail 1 are in guide arm 3 and the slip setting on the bracing piece 2 are in buccal surface pipe 4 on the guide arm 3, be provided with hook 5 on buccal surface pipe 4, buccal surface pipe 4 is located the rear end of guide arm 3, molar antedisplacement device includes elastic webbing 6, the one end setting of elastic webbing 6 is in on the hook 5, the other end setting of elastic webbing 6 is in the front end of guide arm 3. The anchorage nail 1 is designed to be a first anchorage and used as a strong anchorage, and the occlusion of adjacent teeth cannot be influenced or anchorage loss in the moving process cannot be caused.
In this embodiment, the elastic belt 6 is an elastic chain, and a plurality of adjusting holes 7 are formed in the elastic chain along the length of the elastic chain, wherein one of the adjusting holes 7 is hooked on the hook 5; different adjusting holes 7 are hooked on the hook 5, so that the tension of the elastic chain on the buccal tube 4 can be adjusted.
In this embodiment, the support rod 2 and the guide rod 3 are integrally designed, a connecting portion of the support rod 2 and the guide rod 3 protrudes backward to form a protrusion 8, and the end of the elastic band 6 is hung on the protrusion 8. In this embodiment, the support rod 2 and the guide rod 3 are integrally bent from a stainless steel orthodontic wire, and the protrusion 8 is also bent from the stainless steel orthodontic wire.
The utility model discloses a use method as follows: when the elastic chain type molar tooth grinding machine is used, the anchorage nail 1 is arranged on the teethridge 9, the buccal tube 4 is arranged on a molar tooth 10 needing to move forwards, then one end of the elastic chain is hooked on the hook 5, the other end of the elastic chain is hung on the convex part 8, and the stretching length of the elastic chain is adjusted through the adjusting hole 7, so that the forward moving force of the molar tooth 10 is adjusted, the structure is very simple, and the operation is very convenient.
The utility model discloses be applied to the just abnormal technical field of tooth.
Although the embodiments of the present invention have been described in terms of practical solutions, they do not limit the meaning of the present invention, for example, it is not limited to the case of the first molar, but the method is consistent when the second molar is missing and the wisdom teeth are moved forward; for the absence of the first molar, the case method that the second and third molar need to be moved simultaneously is consistent; modifications of the embodiments, as well as combinations with other embodiments, which are apparent to persons skilled in the art in light of the description are deemed to be within the scope of the invention.
