Reamer for operating implant

Abstract

Disclosed therein is a reamer for operating implant, which can very usefully apply an implant operation to a patient who is short of bone quantity to the maxillary sinus, which is easier and safer than a conventional hammering method using a drill and an osteotome or a conventional operation method for transplanting a bone or planting an implant after forming a bone window on a maxillary sinus side wall, and which can reduce a treatment time period and treatment costs by minimizing the patient's pain occurring before and after the operation of the implant. A cutting part of the reamer includes: a protruding face formed on the top surface thereof in such a manner as to upwardly upheave a partial surface including an outer circumference of the cutting part of the entire top surface of the cutting part to form a stepped jaw; a depressed face formed on the top surface thereof in such a manner as to depress a partial surface of the entire top surface of the cutting part to be opposite to the protruding face according to the formation of the protruding face, the depressed face having a reverse inclination in a clockwise direction; a cut edge horizontally formed on a connected portion between the stepped jaw and the protruding face so that the cut edge evenly disperses a force while being in horizontal line contact with the mucosa even though the cut edge is in contact with the mucosa of the maxillary sinus so as to allow a dentist to perform a cutting work safely without damaging a mucosa of a maxillary sinus; and a discharge path longitudinally formed on the cutting part in such a manner as to cut an area ranging from a partial surface of the top surface of the cutting part, i.e., a predetermined portion between the protruding face and the depressed face to a portion which is slightly shorter than the lower end of the cutting part.

Description

technical field [0001] The present invention relates to a reamer for manipulating implants, the reamer being suitable for forming holes in bone for implantation in dental implant surgery, and more particularly to such a reamer for manipulating A reamer for implants that is very useful for implant surgery in patients with insufficient bone volume to the maxillary sinus, as opposed to the traditional percussion method using drills and osteotome and the formation of bone on the side wall of the maxillary sinus It is easier and safer than traditional surgical methods of grafting bone or implanting implants behind the window, and can reduce treatment time and cost by minimizing patient pain before and after implantation procedures. Background technique [0002] In general, an implant originally meant a replacement for restoring lost body tissue when it was lost, but in the field of dental surgery meant the implantation of a denture. [0003] Implantation is a highly advanced tec...

Problems solved by technology

[0015] In addition, due to the irregular size of compact bone fractures and the impossibility of forming holes of ideal shape, it is not possible to obtain primary fixation of helical implants in cortical bone with insufficient remaining bone
