Extension tooth depressor

Abstract

The invention discloses an extension tooth depressor comprising a hollow inner column body, a spring body and an outer sleeve body; the hollow inner column body is adaptively fixed on the upper part of an implant at an edentulous position through a fixing piece, the upper end of the spring body is fixedly welded in the outer sleeve body, and the spring body is cooperatively placed in a hollow pipe of the hollow inner column body; and the outer sleeve body can slide up and down along the hollow inner column body, the top of the outer sleeve body is detachably provided with plastic false teeth, and the plastic false teeth are matched with and abut against the occlusal surfaces of jaw teeth. According to the invention, the pressure abutting against the jaw teeth at the tooth missing position is realized, the pressure in the crown root direction is applied to the extended teeth, the extended teeth are effectively depressed, the due spatial position of the repaired teeth is obtained, and the occlusal plane meeting the physiological requirement is established.

Description

technical field [0001] The invention relates to the field of design and production of special orthodontic appliances and supplies for dentistry, more specifically, an elongated tooth depressor. Background technique [0002] During orthodontic treatment, it is common for patients to have locked teeth. After many teeth are missing, the opposing teeth will gradually elongate and rise above the adjacent teeth due to the lack of contact with the corresponding teeth. This is not only unsightly, but also It is easy to cause food impaction, induce dental disease, periodontal disease, and occlusal interference. Or there is insufficient occlusal space, which cannot be repaired. Therefore, it is necessary to depress the elongated teeth before the tooth restoration to obtain the proper space for the tooth restoration and establish a reasonable occlusal plane of the upper and lower jaws. [0003] The existing treatment plan generally uses grinding to elongate the teeth, and then obtain ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing treatment plan generally uses grinding to elongate the teeth, and then obtain the occlusal space of the repaired teeth, but this plan will cause serious damage to the teeth, resulting in the loss of the enamel layer, exposing the dentin, and sometimes it is necessary to remove the healthy pulp , root canal treatment, so that the tooth tissue becomes fragile and easy to break

[0004] There are also surgical implant anchorages to depress the elongated teeth. Using this method will not only make the patient suffer from the pain of the operation, but also cost more and take a long time. At the same time, the implanted anchorages are easy to fall off, and the lingual side of the mandibular teeth cannot be implanted. This anchorage can only be depressed on one side, which will easily cause the tilt and rotation of the teeth
