Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a half-moon shaped tissue punch used in a flapless implant surgery using a surgeal guide,

The present invention relates to a half-moon shaped tissue punch used in a flapless implant surgery using a surgeal guide, and more specifically, to remove a gum tissue at a position where a fixture (artificial root) is placed at the time of implant surgery The present invention relates to a half-moon shaped tissue punch used in a flap reel implant surgery using a surgeal guide for marking a part to be pulled out in advance in a half moon shape on a gum.

Implants are replacements that can substitute for human tissue when the original tissue is lost, but dental implants are artificially implanted teeth. In other words, a fixture made of titanium or the like which does not have a rejection reaction to the human body can be substituted for the lost root, which is planted in the alveolar bone in which the tooth has escaped, and then the artificial tooth is fixed to restore the function of the tooth.

In the case of general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants can prevent damage to the surrounding dental tissues and can be used stably because there is no secondary cause of tooth decay. In addition, since the implant has substantially the same structure as the natural tooth, there is no pain or foreign body sensation in the gum, and it can be used semi-permanently if it is well managed.

Implant surgery is performed by using a drill to form a hole in the alveolar bone and placing the fixture in the perforation. The operation of placing the drilling and fixture to form the perforation is different for each patient. This is because the position, depth and direction of the implant should be determined in consideration of various factors such as the patient's tooth condition, the position of the tooth requiring the operation of the implant, and the condition of the alveolar bone of the patient.

The drilling operation for alveolar bone drilling has difficulties for an experienced person as well as a beginner to accurately measure the depth and direction in the course of work. Moreover, it is very difficult for a novice who is not experienced in surgery to measure the depth to be drilled during surgery without a separate measurement step.

In addition, when drilling is performed in the alveolar bone, it is very difficult to determine to what extent the drilling operation has been performed to the extent that the operator performs the drilling operation by applying the force to the drill. A deeper depth of deeper than planned may cause serious problems that damage the nerve of the alveolar bone. If the depth of the hole is shallow, excessive force is required to fix the fixture.

In addition, if the perforation depth is shallow, the thread around the perforation may be damaged or the fixture may not be completely fixed, and subsequent reoperation must be performed. A surgical guide was developed to solve this problem. The Surgical Guide is a guide that sets the exact location and direction to perform the drilling operation.

The surgeon guide is usually made of synthetic resin material that is easy to mold and is fixed inside the oral cavity. A guide hole is formed in accordance with the surgical site, and a cylindrical sleeve is inserted in the guide hole. The guide hole and the sleeve are formed in accordance with the angles of the perforation and the fixture, and the outer periphery of the implant drill is rotatably supported on the inner periphery of the sleeve so that drilling or fixture placement is performed.

Implant surgery, on the other hand, can be roughly classified into two types according to the gingival incision method. More specifically, the implant is largely divided into flap implant surgery and flapless implant surgery, depending on whether the gums are completely cut to expose the alveolar bone.

The flap implant surgery is a method in which the gums are widely dissected before the fixture is placed, the alveolar bone is exposed to the outside as a flap composed of the periosteum and the gum tissue is widely exposed, and then drilling is performed in the alveolar bone, Implant surgery is a method of performing surgery by exposing the alveolar bone by forming a hole in the gum that is larger than the drill diameter at the position where the drill is inserted, without incising the gum.

Flap implant surgery is used to incise the bone mucosa when the fixture is placed and to expose the bone by lifting the flap. Generally, since the bone is widely exposed for securing adequate visual field and easy access to the surgical site, Aftereffects such as swelling, pain, and infection may occur. Also, due to damage of the periosteum, bone resorption occurs around the fixture and the rate of osseointegration is low.

On the other hand, since the flapless implant surgery is a method of partially exposing the alveolar bone by forming a hole in the gum corresponding to the drill diameter so that the drill can easily enter without cutting the gum, the probability of occurrence of aftereffects Low operating time, and a higher clinical success rate. In recent years, flapless implant surgery has been the most popular.

The flapless implant surgery is performed by removing the gums to a size of about 4-6 mm to form cylindrical holes, drilling the alveolar bone with a drill having a diameter of 4-5 mm or less therebetween, and then placing the fixture thereon . Recently, with the development of computer tomography and programming technology, the shape of the alveolar bone can be accurately grasped without exposing the surface of the alveolar bone, thereby improving the accuracy of the operation.

During the flapless implant procedure, a dental drill is used to drill a hole in the alveolar bone to remove the alveolar bone. In order to drill, the gingival tissue at the position where the drill is inserted is removed according to the drill size. Tissue punch is used at this time. The tissue of the gums is not rigid, and it is very difficult to drill.

Therefore, the electric toothpaste is usually used to remove the gingival tissue at the position where the implant is to be implanted first, and then to perform the drilling operation. Most of the tissue punches used in the flapless implants are formed in a cylindrical shape with a punching portion, thus forming circular incision marks on the gums at the positions where the implants will be placed, as shown in the reference photograph of FIG.

In all cases, however, tissue punches can not be used. The gingiva has attached gingiva and oral mucosa. The attached gingiva is hard and healthy gums, but it is better because the gingiva is disappeared due to gingival diseases and the gingiva attached to the implant surgery site is totally absent or very insufficient. In this case, the tissue punch There is a problem that it is difficult to use.

The problem to be solved by the present invention is to use a surgeon's guidewire in the case of insufficient gingiva in the implant surgery to mark the exact boundary where the implant will be placed, thereby forming a mini-flap, a tissue punch is used to provide a half-moon shaped tissue punch for use in a franchise implant surgery using a surgeon guide that can eliminate all of the attached gingiva or form a common valve to reduce unnecessary tissue damage

According to the present invention as a solution to the problem,

In order to protect the attached gingiva at the site where the implants will be implanted during the implant surgery using the surgeon guide, it is necessary to mark the area where the mini-flap is to be formed on the gum accurately,

A body portion having a semicircular sectional shape having an arcuate guide surface in contact with the inner circumferential surface of the sleeve of the surge guide;

A shank portion connected to an upper end of the body portion and extending in a first direction and bent in a second direction perpendicular to the first direction;

A punching blade disposed in a concentric manner in the radial center of the body portion; And

And one or more bridges connecting the body and the punching blade. The present invention also provides a half-moon tissue punch for use in a flapless implant surgery using a surgeon guide.

Here, the punching blade applied to the present invention may have a half-moon shaped center blade and right and left side blades extending linearly from both ends of the center blade toward the body part.

Preferably, the punching blade can be detached from the bridge and replaced.

In this case, the punching blade can be replaced by a structure in which the punching blade is made of a metal material having magnetism and a magnet is mounted on a bridge portion where a part of the punching blade contacts.

Further, in the case of a punching blade interchangeable type, a stopper for restricting the punching blade from being pushed in the first direction between the punching blade and the gingival tissue due to an external force acting on the punching blade through the shank portion during surgery, And can be integrally formed on the inner side.

Further, in the half-moon shaped tissue punch used in the flapless implant surgery using the surge guide according to the present invention, the punching blade protrudes further downward than the lower end of the body with respect to the first direction, It is desirable to prevent damage to the gums and the like caused by contact of the body part with the contacted gum tissue.

According to the embodiment of the present invention, since the implant can be cut out in a circular arc shape on the gum at the position where the implant is to be placed before the drill is used, the implant can be used even when the gingiva is not completely or very little on the site to be implanted, Then, the gingival tissue can be precisely cut along the arc-like incision mark and can be peeled off, thereby maximally protecting the attached gingiva.

In some embodiments configured to allow the punching blade to be removed and replaced from the bridge, the punching blade can be immediately replaced in accordance with the health condition of the gums, and more specifically, the thickness of the attachment tooth at the location where the implant is to be placed There is an advantage that it is not necessary to provide a plurality of punches having different sizes of punching blades.

FIG. 2 is a bottom perspective view of a half-moon shaped tissue punch used in a flapless implant surgery using a surgeal guide according to a first embodiment of the present invention, FIG. 3 is a perspective view of a flapless implant using a surge- 1 is an enlarged view of a body part of a half-moon shaped tissue punch used in surgery. And Fig. 4 is a front view of the body part shown in Fig.

Referring to FIGS. 2 to 4, the half-moon shaped tissue punch 50 used in the flapless implant surgery using the surgeal guide according to the first embodiment of the present invention has a fixture (implant) ) Is a tool for marking the part to be removed when the gingival tissue is removed at the position where the gingival tissue is placed. Specifically, it includes a body portion 52, a shank portion 54, a punching edge 56, and a bridge 57.

The body 52 may have a semicircular cross-sectional shape having an arc-shaped guide surface 520 contacting the inner circumferential surface of the sleeve of the surge guide 40 (see FIG. 7 to be described later) A shank portion 54 extending in a height direction (hereinafter, referred to as a "first direction") of the body 52 in the drawing and bent in a second direction perpendicular to the first direction is connected to the shank portion.

In the case where the shank portion 54 is elongated straightly with respect to the first direction, access to the molar can be difficult in the mouth structure. Therefore, as shown in the drawing (FIG. 2), it is preferable to have a structure that can easily and smoothly approach the molar in the oral cavity by being bent at a predetermined height at right angles.

A gripping surface 540 having an irregular morphology or a rule for gripping the user may be formed on the upper outer surface of the shank portion 54 away from the body portion 52, The punching blade 56 may be disposed concentrically with the punching blade 56. The punching blade 56 may protrude further downward than the lower end of the body 52 with respect to the first direction as shown in FIG. .

When the punching blade 56 projects further downward than the lower end of the body 52 with respect to the first direction, the portion to be detached from the gum at the position where the fixture is inserted is punched It is possible to reliably prevent damage to the gums caused by the contact of the body part 52 with other parts other than the part of the gum where the punching blade 56 touches when displaying using the body 56. [

The punching blade 56 preferably has a half-moon shaped center blade 560 and a pair of right and left side blades 560 extending linearly from both ends of the center blade 560 toward the body portion 52 562L, and 562R. At this time, since the half-moon center blade 560 can be manufactured in various sizes depending on the application environment, the size, the curvature, and the radius of curvature are not limited to specific numerical values.

The bridge 57 connects the body 52 and the punching blade 56 and serves as a bridge for integrating the body 52 and the punching blade 56. One or more, preferably two, bridges 57 may be formed between the body portion 52 and the punching edge 56, and in some cases, the plane of the space between the body portion 57 and the punching edge 56 Or may be formed as a plate having a shape corresponding to a shape (annular shape).

FIG. 5 is an exploded perspective view showing an enlarged main part of a half-moon shaped tissue punch used in a flapless implant surgery using a surgeal guide according to a second embodiment of the present invention, FIG. 6 is a perspective view FIG. 2 is a side view of a body part of a half-moon tissue punch used in a flap-reel implant surgery using the present invention.

The second embodiment of Figs. 5-6 is contrived for the case where it is necessary to replace the punching blade 56 with a punching blade 56 of different size depending on the state of the gum region of the surgical site, Only the punching blade 56 can be separated from the punching blade 57 and replaced with a new one.

The punching blade 56 may be made of a metallic material having magnetic properties and the punching blade 56 may be formed of a metal material such that a part of the punching blade 56 contacts The punching blade 56 can be easily attached and detached by using the attractive force between the magnet and the punching blade 56 by mounting the magnet on the bridge 57. [

5 and 6, when an external force is applied to the punching blade 56 through the shank 54 at the time of the operation, The punching blade 56 can be pushed in the first direction. Therefore, a stopper for restricting the movement of the punching blade 56 in the first direction may be integrally formed inside the body 52 at the upper end of the punching blade 56.

Hereinafter, an incision is made in the gum using a half-moon shaped tissue punch used in a flapless implant surgery using the above-described surge arrester, the gum tissue is cut along the incision mark, and the alveolar bone A brief description will be given.
