Description

Extension tooth depressor

Technical Field

The invention relates to the field of design and production of dental special-purpose corrective appliances and articles, in particular to an elongated tooth depressor.

Background

In orthodontic treatment, teeth of common patients have locked relationship, and after a plurality of teeth are lost, the teeth of the jaw are gradually stretched and higher than adjacent teeth due to lack of contact of the corresponding teeth, so that the teeth are not beautiful, and are easy to cause food impaction to induce odontopathy, periodontal disease and occlusion interference. Or the occlusion space is insufficient and the tooth can not be restored, so that the elongated tooth needs to be depressed before the tooth restoration, the due space for the tooth restoration is obtained, and a reasonable occlusion plane of the upper jaw and the lower jaw is established.

However, the existing treatment scheme generally adopts grinding of the elongated teeth and then obtaining of the occlusal space of the restored teeth, but the scheme can cause serious damage to the teeth, loss of enamel layers and exposure of dentin, and sometimes needs removal of healthy dental pulp and root canal treatment, so that dental tissues become fragile and easy to break.

Also adopt the operation to plant the anchorage and carry out the holding down to the extension tooth, adopt this scheme not only can let the patient bear the misery of operation, and the cost is also comparatively expensive moreover, and is long, and simultaneously, the anchorage body of planting drops easily, and this anchorage can not be planted to lower jaw odontoglossal side, can only carry out unilateral holding down, leads to the fact the slope and the rotation of tooth easily.

Therefore, the tooth depressor is designed in the scheme, the traditional treatment scheme and the traditional treatment mode are changed, namely, the anchorage is not needed to be planted, the operation pain is reduced, the treatment cost is reduced, the corresponding teeth at the missing position can be continuously and stably pressed, the extended teeth are effectively depressed, meanwhile, the normal occlusion of the teeth is not influenced, and the patient can eat the food normally.

Disclosure of Invention

The present invention discloses a tooth depressor, which mainly aims to overcome the above disadvantages and shortcomings of the prior art.

The technical scheme adopted by the invention is as follows:

the utility model provides an extension tooth depressor, cylinder, spring body and outer sleeving body in including the cavity, the cylinder passes through the mounting adaptation to be fixed on the planting body upper portion of scarce tooth department in the cavity, the fixed welding in upper end of the spring body in the outer sleeving is internal, just the cooperation of the spring body put in the cavity of cylinder, the upper and lower direction of cylinder slides in this outer sleeving body can follow the cavity, the plastic denture has been installed to the top detachably of outer sleeving body, and this plastic denture is anastomosed mutually with the occlusal surface to the jaw tooth and is supported the top.

Still further, the plastic denture has the multilayer, is the formula of stacking and installs the structure, along with the going on of holding down, when the spring force of spring body is not enough, and extension tooth has upwards pushed back a bit promptly, and at this moment, through increasing the plastic denture that stacks, can keep pushing up state and dynamics, continue to carry out lasting holding down to extension tooth.

As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages:

1. according to the invention, by arranging the hollow inner cylinder, the spring body and the outer sleeve body, crown-root pressure can be applied to the elongated teeth, so that the teeth can be effectively subjected to depressing treatment, a due space position can be obtained for the restored teeth, a physiologically-conforming occlusion plane is established, and the teeth are more attractive and healthy after being restored.

2. The invention can continuously and stably apply elastic resisting force to the teeth through the spring body, and simultaneously, effectively matches the occlusion of the corresponding teeth of the missing position, so that a patient can normally eat in the process of depression without influencing the correction, and the pain of the operation and the treatment cost are reduced.

3. The invention has simple and exquisite structure, reasonable and practical function, stable and obvious effect, and very convenient installation and operation, is very beneficial to the operation installation and use of doctors, and has very high practical application and popularization value.
