Description

Implant alveolar bone trimming drill

Technical Field

The utility model relates to the technical field of dental implant equipment, in particular to an alveolar bone trimming drill for dental implant.

Background

This section is intended to introduce the reader to various aspects of art that may be related to various embodiments of the present invention and is believed to provide the reader with useful background information to facilitate a better understanding of the various aspects of embodiments of the present invention. Accordingly, it should be understood that the description in this section is for purposes of illustration and is not an admission of prior art.

The tooth loss rate of the middle-aged and the elderly is very common, the average number of teeth left in the population of 65-74 years old is 20.97/32, and the oral implant restoration is in a rapid development stage along with the increase of the dominative income of all people, so that the tooth loss rate becomes the primary restoration mode of the tooth loss of the middle-aged and the elderly. In the aged 65-74 years, 86% of the aged have tooth loss, the proportion of the whole mouth without teeth is 4.5%, and the proportion of the repaired tooth loss is 63.2%.

The implant can obtain the repairing effect which is very similar to the function, the structure and the beautiful effect of the natural tooth, and becomes the first-choice repairing mode of more and more patients with tooth deficiency. The dental implant refers to a tooth missing restoration method for supporting and retaining an upper dental restoration based on a lower structure implanted into bone tissues; pure titanium metal with high compatibility with human bone is precisely designed to be manufactured into a cylinder or other shapes similar to a tooth root in a medical mode, and is implanted into an alveolar bone of a tooth lacking area in a surgical minor operation mode. After 1-3 months, according to the situation of osseointegration in the oral cavity, the covering screw of the previous time is taken down, the abutment is installed, and then the full-porcelain or porcelain dental crown is made on the artificial tooth root, thus completely completing the oral implantation.

As shown in fig. 1, the long-term loss of natural teeth causes the alveolar ridge 11 to become narrow and low due to the difference in the shape of each individual alveolar bone 1. The alveolar ridge 11 may have a significant difference in height from missing tooth to missing tooth. When the half-mouth or full-mouth tooth is implanted and repaired, a plurality of implants 2 are stressed at the same time, and the shoulder horizontal height of each implant is consistent with the same level, which is most reasonable. For such alveolar ridges 11 with different heights, an apparatus is urgently needed to trim the alveolar bone with inconsistent heights on the front and back or two sides or the edged alveolar ridge crest to the height as close to the same height as possible of the alveolar ridge crest at each tooth position.
