Description

Dental drill guiding device structure

Technical Field

The present invention relates to a dental drill guiding structure, and more particularly to a guiding and positioning device for a dental drill drilling device, which can effectively guide the drilling operation of a dental drill to drill out an ideal hole.

Background

In order to avoid the situation, damaged teeth are often replaced by false teeth, and the most common treatment method is artificial tooth implantation nowadays. The artificial tooth implantation is that a cavity with proper size is drilled in an alveolar bone at the edentulous position of a gum in the oral cavity of a patient, then an artificial tooth root is implanted in the cavity, after the artificial tooth root grows together with self tissues through osseointegration, a supporting platform is fixed on the artificial tooth root, and finally an artificial tooth crown is sleeved on the supporting platform to achieve the purpose of recovering the occlusion function of the tooth. The existing drilling technology for drilling the cavity in the alveolar bone is that one hand of a user holds a dental drill and the other hand holds a digging rod to prop open the oral cavity, so that the dental drill is used for drilling the affected part, if the drilled affected part is positioned at the front row of teeth, the method is still used, but if the affected part is positioned at the rear side teeth, the drilling work of the user is blocked greatly. Current techniques may fail to drill the desired holes, or damage adjacent teeth and nerves, or even create perforations; therefore, in addition to increasing the instability during drilling, the drill bit is easy to displace due to the lack of support, which causes great trouble during operation. In view of the above, there is a need in the art for improvements in how to stabilize a borehole.

The present inventor has made intensive studies on the above-mentioned problem of drilling alveolar bone and has made extensive studies by years of development experience of related articles to develop a solution for overcoming the above-mentioned problems of the prior art.
