Abstract:
The present invention relates to a surgical instrument for collecting autologous bone. The surgical instrument for collecting autologous bone comprises: a handle portion connected to a driving device; and a cutting portion which collects bone pieces of a person to be surgically operated on while rotating, wherein the cross-sectional area of the cutting portion is 10-40 % of the area of an imaginary circle having a diameter which is the distance from the center thereof to the outermost portion.
Abstract:
The present invention relates to a membrane for alveolar bone regeneration, and more specifically, to a membrane for alveolar bone regeneration which guides bone regeneration by covering an implant filling a bone defect region, comprising: a coupling portion which comprises a central hole for allowing an insertion body for an implant to be inserted into alveolar bone to penetrate through, and is coupled to the insertion body for an implant; a lateral bent portion which is bent downward from the coupling portion and as a whole forms a curved shape; and lateral cover portions which are protruded from both edges of the lateral bent portion and are bent toward the defect region of alveolar bone, wherein the lateral bent portion and the lateral cover portions are three-dimensionally formed in advance so as to fit the final shape of the alveolar bone to be regenerated.

Abstract:
The present invention relates to a drill for an implant surgery which allows a mucous membrane in the maxillary sinus to be fast and safely lifted without being damaged during a surgery for the maxillary sinus. According to the present invention, an drill for use in an implant surgery includes a connection portion formed at an upper end of a body of the drill to be connected with a driving device; and a cutting portion formed at a lower end of the body and having a cutting blade for drilling, wherein an outer circumferential edge of a distal end of the cutting portion protrudes rather than a center of the distal end of the cutting portion.
Abstract:
The present invention relates to a dental drill for quickly and safely lifting the sinus without damaging the mucous membrane therein when operating the sinus. The dental drill, according to the present invention, comprises a connection portion which is formed on the upper end of a body so as to be connected to a driving device, and a cutting portion, which is formed at the lower end of the body, having cutting blades for drilling, wherein the cutting portion comprises a plurality of cutting blades which are arranged in a circle so as to have a cylindrical shape with an empty hollow inside to allow collection of a main disk, and wherein the cutting blades are provided with an curved surface end at the end, which is rounded, so that damage to the mucous membrane can be prevented even when the outer circumferential edge of the end of the cutting portion comes into direct contact with the mucous membrane when drilling.
