Description

Drill bit for operating procedure

The present invention relates to a drill bit for an implant procedure, and more particularly, to a drill bit for an implant procedure that can quickly and safely cut a bone during an implant procedure and prevent damage to the maxillary sinus mucosa.

In general, it is encouraging that many people improve their diet, such as height and weight, by improving their diet, but the health of their teeth deteriorates as they prefer soft, sweet foods. The need for more is being increased.

 In response to these demands, there have been many technological innovations in dentures, and modern advanced technologies have developed dentures that are harmless to the human body and have little rejection, so that physiological disorders do not occur even if they are attached to the human body for a long time.

 Dental implants, which have recently been commonly used as such dentures, are embedded with a screw-shaped artificial tooth fixture made of titanium on the part where the tooth is lost to fuse with bone for a period of time. Abutment (abutment) as a connecting member on the top, and then by fixing a prosthesis such as artificial teeth (crown) is a cutting-edge procedure that can restore the original function of the teeth.

On the other hand, the posterior maxillary sinus is weak, and the posterior molar is a particularly difficult site during implantation. When implanting in this area, lateral approach maxillary sinus findings and osteotomical sinus findings are usually used.

Among these, lateral approach maxillary sinus traction surgery requires a high level of skill and is difficult to perform, and the implanted bone needs to take a lot of time to become osteoporosis.

On the other hand, osteotomical maxillary sinus surgery is a method of forming a hole down the maxillary sinus mucosa using a drill, gradually tapping with a large diameter osteotomes, and gradually inserting a graft into the bone.

However, when using a drill to form a hole down the maxillary sinus mucosa, conventional drills cannot discern the depth of the hole and the maxillary sinus mucosa is torn or damaged when the cutting edge concentrates vertically and contacts the maxillary sinus mucosa. There is a concern that it is difficult to maintain and secure bone graft material has a problem that the support capacity of the implant falls.

In addition, the conventional drill bit for preventing damage to the maxillary sinus mucosa has a problem that the cutting edge is formed only on a part of the top of the head so that the cutting force is long and the procedure time is long.
