Description

Drill for implant operation

According to the present invention, when forming a hole for embedding a fixture, which is an artificial tooth, in the tooth loss part, the hole is precisely set to a depth set even in a narrow space and a dark place in the oral cavity by an identification part formed on an outer surface of a drill. The present invention relates to a drill for implant surgery to allow drilling.

More specifically, the present invention relates to a drill for implant surgery, which makes it easy to check the identification groove formed in an annular shape on the outer surface of the drill when the drill is rotated so that the hole set for planting the fixture in the alveolar bone can be easily drilled in a safe state. .

In general, an implant is an artificial tooth formed from screw-shaped titanium (Ti), which is a human-friendly material in the alveolar bone, ie, a bone around the implanted fixture after planting a fixture in the alveolar bone by drilling. When fused and hardened, the abutment is tightly bonded to the fixture, and the prosthesis, which is an artificial tooth, is bonded to the abutment.

Compared to the bridge, the most common method of tooth restoration, the implant can be performed only on the damaged area without damaging the adjacent teeth or soft or surrounding tissue, and is maintained and supported by the bone tissue so that the force in the bone tissue is continuously maintained. Implantation is a global trend in dental restoration because it can delay the absorption of bone tissue and restore the chewing ability to the same level as natural teeth, and aesthetically similar to natural teeth.

On the other hand, drilling is performed to drill the hole for fixing the fixture to the alveolar bone at a specified depth, taking an X-ray picture with the surrounding teeth in consideration of nerve position and the like. Since the work is difficult, the operator's field of vision may be obstructed due to the blood generated during the puncture, and a safety accident may occur. There is a problem that requires a re-surgery because of the difference in height between the teeth and the implant procedure failed.

In view of this, as in the conventional drill for implantation shown in FIG. 1, a black strip 2 of laser processing is formed on the outer surface of the drill 1 to correspond to the depth of the hole for planting the fixture in the alveolar bone. As it is formed, the operator can drill by the depth set in the alveolar bone of the subject in the narrow space in the oral cavity by the identification of the band (2).

However, impurities harmful to the human body generated when forming the strip 2 by laser processing on the outer surface of the drill 1 penetrate into the bone tissue of the alveolar bone during perforation, thereby impairing dental health, and in particular, a person whose vision is poor. In this case, it is difficult to identify the band 2 formed on the outer surface of the drill 1 in the narrow oral cavity when the drill 1 rotates, so that the procedure is difficult and a safety accident may occur.

An object of the present invention, when rotating the drill to form a hole for embedding an artificial tooth fixture in the alveolar bone, it is easy to check the identification portion formed on the outer surface of the drill in a narrow space and a dark place in the oral cavity to ensure safety The idea is to provide a drill for the implant procedure to work with.

Another object of the present invention, the implant formed in the annular portion on the outer surface of the drill is formed during the drilling process implant implants to prevent damage to the health of the subject by infection of bone tissue during puncture of the alveolar bone corresponding to the depth of the fixture To provide a drill.

Still another object of the present invention is to drill holes precisely in the alveolar bone at a predetermined depth to achieve harmony between artificial teeth and peripheral teeth, and to prevent damage to nerves in the alveolar bone during puncture of the alveolar bone, thereby ensuring reliability of the procedure. It is to provide a drill for implant surgery to improve the.
