Description

Dentist bone drilling positioning guide

The present invention relates to a bone drilling positioning guide device, in particular to a dental bone drilling positioning guide device in which the distance between the two extending portions is smaller than the diameter of the inner wall surface.

A tooth is a calcified tissue used to chew food. When an adult's teeth are damaged by oral diseases or external forces, it cannot be regenerated. After the tooth is damaged, the alveolar bone and gums may shrink and the feeding function is affected. In the case of dentures, which have often replaced damaged teeth, the most common treatment today is manual implants.

When the teeth are damaged or removed, the general treatment method is to install dentures instead of the original real teeth. The current common method of installing dentures is to use fixed artificial implants. The fixed artificial implant is to first drill a proper size cavity in the proper place of the gum in the patient's mouth, and then implant an artificial root in the cavity and suture the wound, and the artificial tooth is rooted on the dental bone. After being completely long together, the abutment teeth with screws are locked on the artificial roots, and artificial prostheses are finally placed on the teeth of the abutments. The artificial root and the abutment tooth with the screw can support the artificial tooth completely by the gum bone, thereby enabling the artificial tooth to withstand the bite force of the upper and lower teeth, and achieve the purpose of restoring the bite function of the tooth.
