BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental drill, and more particularly, to a dental drill that is used primarily to form holes of a certain size in the jawbone during the implantation.

In recent years, there have been many technical innovations in the field of dentistry, and these technological innovations have led to the development of artificial teeth, or implants, made of titanium, which are harmless to the human body and have little rejection and thus have little physiological side effects even if they are attached to the human body for a long time.

The implant procedure involves drilling a hole of appropriate diameter in the jaw bone using a drill, and then fixing the artificial fixture fixture firmly through the screwdriver.

And the entire process is completed by fixing the artificial teeth on the top of the fixture.

On the other hand, the length of the drill is fixed because the length of the drill is short, if the procedure is inconvenient or difficult to use a separate drill extension mechanism is connected to the drill.

As shown in FIG. 1, conventionally, the shank 2 is inserted into the shank insertion opening 1 of the drill extension mechanism 10 so that the flat portion 3 provided at the rear end of the shank 2 has a fixed taper surface ( 4) It is fixed by being inserted into the inclined bottom surface by wedge method. However, if force is applied to the shank 2 when the shank 2 is forcibly fitted to the shank insertion hole 1 of the drill extension mechanism 10, the rear end of the shank 2 is the bottom of the drill extension mechanism 10. When the phenomenon occurs that the surface is compressed to finish the drilling work and try to separate the shank (2) from the drill extension mechanism 10 there is a problem that does not separate well.

In addition, there is a disadvantage that the service life of the drill 5 is relatively shortened due to the rear end wear of the shank 2.

In addition, there is a limit in stably maintaining the engagement state such as the possibility of idling of the shank (2).

The present invention has been made to solve the above problems, and an object of the present invention is to provide a dental drill that can be extended in length without using a drill extension mechanism.

It has its technical features.

The anti-rotation protrusion and the anti-rotation groove preferably have an angled shape so as to prevent idle rotation in a coupled state.

It is preferable that a tool through hole communicating with the rotation preventing groove is formed outside the shank coupling part.

The depth of the anti-rotation groove is formed to be deeper than the length of the anti-rotation protrusion, it is preferable to allow a clearance even if the anti-rotation protrusion is coupled to the anti-rotation groove.

And the present invention drill portion; Shank portion disposed in line with the drill portion; A shank coupling part provided at a rear end of the shank part and having a tapered shape fitting protrusion and a rotation preventing protrusion integrally extending from the tip of the fitting protrusion; It is provided at one end of the drill portion, the fitting protrusion is formed to include a drill coupling portion is formed in the tapered-shaped fitting groove and the rotation preventing groove is in communication with the fitting groove is coupled to the fitting groove is coupled to the fitting groove. It has its technical features.

As shown in Figures 2 to 4, the removable drill according to the present invention is a drill portion 20; Shank portion (30) disposed in line with the drill portion 20; A drill coupling portion 40 provided at the rear end of the drill portion 20; It is provided on one end of the shank portion 30, and comprises a shank coupling portion 50 coupled to the drill coupling portion (40).

The drill part 20 is for forming a hole having a certain size and depth in the artificial bone, that is, the jaw bone to implant the implant, and not only has a groove through which bone powder generated when the hole is formed can escape. Two or three or more teeth are provided.

The diameter, length, etc. of the drill part 20 can be selected suitably and used as needed, of course.

The shank portion 30 has a cylindrical structure having a predetermined length and diameter, and a hook-shaped handpiece fixing part 32 for fixing to a handpiece (not shown) is formed at a rear end thereof.

The shape of the handpiece fixing part 32 can be changed within a range capable of stably maintaining the fixed state to the handpiece (not shown).

The drill coupling portion 40 may have an integral structure with the drill portion 20 or may have a removable structure.

The drill coupling portion 40 is formed with a tapered shape protrusion 42 and a rotation preventing protrusion 44 of a quadrilateral shape integrally extending from the tip of the fitting protrusion 42, respectively.

At this time, the reason why the anti-rotation protrusion 44 has an angled shape is to prevent idling.

Shank coupling portion 50 has a cylindrical structure, the taper-shaped fitting groove 52 and the fitting groove 52, the fitting protrusion 42 of the drill coupling portion 40 is forcibly fitted to the shank coupling portion 50. In communication with the rotation preventing groove 54 is inserted into which the rotation preventing projection 44 of the drill coupling portion 40 is formed.

Shank coupling portion 50 may have an integral structure with the shank portion 30 or have a removable structure, the length can be adjusted by making the length of the shank coupling portion (50) in a variety.

The outside of the shank coupling portion 50 is formed with a tool through-hole 56 of a predetermined size in communication with the rotation preventing groove 54, the size and shape of the tool through-hole 56 can be appropriately adjusted as needed. Do. And the depth of the anti-rotation groove 54 is formed deeper than the length of the anti-rotation protrusion 44 of the drill coupling portion 40 so that the anti-rotation protrusion 44 of the drill coupling portion 40 of the shank coupling portion 50 Even when coupled to the anti-rotation groove 54, the free space (S) is to be generated.

Accordingly, when the drill coupling portion 40 and the shank coupling portion 50 are separated, the separation tool introduced through the tool through hole 56 can be inserted, so that the separation operation can be performed more easily.

The anti-rotation groove 54 has a quadrangular shape corresponding to the shape of the anti-rotation protrusion 44 so that the anti-rotation protrusion 44 can be effectively prevented from being idle in the coupled state.

On the other hand, each of the anti-rotation protrusions 44 and the anti-rotation groove 54 may have a variety of shapes, such as polygons within a range that can be prevented from idling in the coupled state.
