Description

A dental blade having the cutting edge bended from its body with a first and an opposing second face} having a first knife and a second knife and having a cutter portion inclined at an angle with respect to the front end portion

The present invention relates to a dental blade, more specifically, the cutter portion is bent at an angle of 20 to 60 degrees forward with respect to the front end portion is formed integrally with the front end portion, and consists entirely of plate-shaped, the cutter portion is the front portion And a second knife that is knife-processed on the rear side of the first knife and a first knife machined on the rear surface thereof, and the second knife has a dental blade having an indented knife structure which is indented and knife-processed inwardly. It is about.

In dental procedures such as implantation, tooth decay, and prosthetic treatment, a dental blade is used to incise the gum at the surgical site. Such gum cutting blades are used in many implant procedures, especially for functional restoration and aesthetic effect of damaged teeth.

In general, implantation is performed by cutting the gums of the area to be implanted, drilling a hole in the gum bone, and then inserting various types of titanium or alloy alloy implants that can function as artificial roots. After a sufficient period of time to combine with the gum bone, the artificial tooth is connected to the upper part of the implant.

During the implantation procedure, a step of cutting the gum using a blade is required, and the gum of the surgical site is cross-cut using a dental blade, which is generally called a scalpel.

1 is a view of a typical representative dental blade, Figure 2 is a schematic diagram of a surgical scene using a conventional blade. Referring to these drawings, the conventional dental blade 100 is formed of an integral structure in which the cutter portion 110 extends in the longitudinal direction with respect to the front end portion 120.

The conventional blade scalpel has a shape in which the cutter portion 110 of the blade protrudes forward in the longitudinal direction with respect to the front end portion 120 of the blade, the blade 100 of this type is a blade holder ( 2: 300).

Therefore, when using a conventional blade, such as a scalpel, it is difficult to precisely incise gums due to the narrow structure inside the oral cavity in which the incision is performed, and particularly for forming a partial thickness flap, which is a step of the implant procedure. There is a problem in that it is difficult to approach the cutter portion of the blade to the site to be cut during the procedure.

Specifically, as shown in FIG. 2, the implant surgery of the posterior part requires the gum incision of the incision 6 corresponding to the position where the implant is to be placed, which is the tooth of the tooth 5 located in front of the incision 6. Between the posterior face and the anterior face of the tooth 7 located behind the incision 6, using a conventional blade 100, such as a scalpel, the posterior face of the anterior tooth 5 for implant placement. Since the incision to the front surface of the rear tooth (7) to be placed and the implant is not easy in the oral structure, there is a problem that the precise procedure for the incision (6) is difficult. In addition, even if the use of some blades, rather than a complete straight, the effect is not sufficient, and the precise procedure for the incision is impossible.

In addition, the conventional blade is only processed on the front portion of the knife, the blade is used during the procedure is limited to the front portion where the knife is processed, when cutting the suture chamber was troublesome to use additional tools such as scissors.

Therefore, there is a need for the development of a new type of blade suitable for use in dental surgery, especially considering the narrow oral structure during implantation.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

Therefore, the dental blade according to the present invention is a blade used to cut the gum during the dental procedure, the cutter portion is bent at an angle of 20 to 60 degrees forward with respect to the front end portion is formed integrally with the front end portion, as a plate-like overall The cutter portion includes a first knife that is knife-processed on the front side and a second knife that is knife-processed on the rear side in succession to the first knife, and the second knife is indented inwardly and knife-processed. The knife structure is formed.

Here, the cutter part has a structure having a first knife knife-processed in the front part and a second knife knife-processed in the rear part subsequent to the first knife. That is, unlike the conventional blade in which the knife is formed only in the front part, the cutter part of the blade of the present invention is formed with the second knife in the back part in succession. Therefore, a double blade may be used during the procedure, for example, when the blade is pulled inward with respect to the surgical site, and the incision is performed by using the first knife on the front side and the blade is pushed outward with respect to the surgical site. , The second knife of the rear part can be used.

The angle of the cutter portion may vary as necessary to allow the operator to work in a comfortable and stable posture, for example, based on the front end of the blade to facilitate access to the posterior portion and to more accurately incision the incision. It is preferable to incline 20 to 60 degrees forward.

Therefore, the blade according to the present invention is formed integrally with the shear portion while forming a predetermined angle with respect to the shear portion, compared to the conventional blades formed in the longitudinal direction, more precisely the desired gum area during the dental procedure Incision can be made, and even a patient with a narrow gum structure allows the operator to perform the procedure more delicate and stable.

In particular, the blade structure of the present invention, the cutter portion is bent at a predetermined angle with respect to the front end portion during the implantation procedure can be very easily applied to the incision of the posterior part as well as the incision of the anterior and premolar parts.

Furthermore, the second knife further includes an indented knife structure in which the knife is indented while being cut inwardly, so that after cutting the incision in the oral cavity, the cutting of the suture chamber can be easily performed without using scissors. .

For reference, the indented knife structure means a knife structure in the form of a groove for cutting the suture chamber.

More preferably, the cutter portion may have a structure inclined at an angle of 40 degrees to the front of the blade front end portion.

In one preferred embodiment, the front end portion comprises a coupling portion consisting of a stepped structure in which the hollow width gradually decreases from the bottom to the top direction to facilitate engagement with the dental blade holder, the blade and the blade holder in one operation Can be easily removed.

The number of steps in the stepped structure of the coupling portion may vary as necessary, for example, may be composed of 2 to 5 steps, preferably may be composed of 2 to 3 steps.

On the other hand, the dental blade holder is formed in a straight shape as a whole, or may be a curved structure for convenience, the blade of the present invention can be used to be mounted to the blade holder of various forms as necessary. Preferably, when using the blade of the present invention mounted on a conventional straight dental blade holder, due to the blade structure of the present invention having a predetermined angle can be performed precisely and stably the treatment of the desired gum area. .

The first knife is not particularly limited as long as it is a structure for cutting the gums and cutting tissue during the procedure, for example, may have a structure in which the end is gently curved upward. For reference, the gently curved end portion means that the end portion has an arc shape and the bending angle is upwardly curved with the angle of 100 degrees to 170 degrees.
