JP2000051237A - Jig for dental implant - Google Patents

Abstract

PROBLEM TO BE SOLVED: To efficiently carry out the assembly or disassembly of an implant such as dental artificial dental root, etc., with a simple constitution by providing a jig for implant with two ends for holding and clamping the jig, forming an open hole part opened at its front end at the one end thereof and likewise forming a hole part in the state dealing with this open hole part at the other end. SOLUTION: The clamping tool comprises a main body 11 which is the portion to be held by the hand and the hole parts 12 which are respectively disposed at its two ends and open hole part 14 which opens in a front end direction. A recessed part 13 is formed at the circumferential edge of the hole part 12. At the time of coupling a dental root lower part 23 and dental root upper part 22 formed with coating layers 24 to the peripheral of the artificial dental root of a two-piece type, the head part of the dental root upper part 22 is pressed to the recessed part 13 and the bottom thereof is pressed thereto so as to be held by the open hole part 14. The main body 11 is then clamped by holding the same with the fingers from both sides. The dental root upper part 22 is thereafter arranged on the dental root lower part 23 and a screw 21 is inserted through the hole part 12 from an upward direction and is screwed to a threaded female part 25, to couple the dental root upper part 22 and the dental root lower part 23.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for a dental implant.

[0002]

2. Description of the Related Art Recently, artificial dental roots have become popular due to their improved performance. However, since artificial dental roots are inherently small, they must be handled carefully, but these are not suitable for living organisms. Since it is used for implantation in hard tissue or as a substitute, it requires a certain amount of work inevitably.

[0003]

In particular, in the case of an artificial tooth root which is divided into a plurality of pieces, such as a two-piece type, and which is attached and detached over time and implanted, the parts become finer and the handling becomes more complicated. Was to become. This point is 2
The same applies to dental implants that work in the oral cavity, not just the pieces.

[0004]

According to the present invention, there is provided a jig capable of securely grasping such a part and performing an operation such as a surgical operation in that state. In other words, "It has two ends for grasping by sandwiching the implant tool, and one end has
A dental implant jig in which a release hole having a free end is formed, and a hole is formed in the other end in a state corresponding to the release hole. It proposes. Basically, the present invention is a jig for holding in a sandwiching manner like tweezers. Therefore, a configuration such as scissors or pliers may be used. The end, which is a portion to be directly gripped, has a release hole and a hole, and is configured to grip the upper and lower parts. In addition, a configuration in which a recess is provided around the hole so that the implant component can be used more stably in the present invention can be shown.

[0005]

FIG. 1 is a diagram showing an embodiment of the present invention.
FIG. 1A is a view as viewed from above, FIG. 1B is a view as viewed from below, and FIG. 1C is a cross-sectional view in the side direction. The gripper 10 according to the present invention includes a main body 11 as a part held by a hand.
And a hole 12 provided at each of two ends of the main body 11 and a release hole 14 opened in the distal direction.
The hole 12 and the release hole 14 are formed at positions facing each other, and a recess 13 is formed on the periphery of the hole 12.

FIG. 2 shows an example of use of the present invention when the lower root 23 and the upper root 22 in which a coating layer 24 of hydroxyapatite is formed around a two-piece type artificial root are actually screwed. The upper root 22 is the upper root 22
Is applied to the concave portion 13 on the periphery of the hole portion 12, and the bottom portion is sandwiched by the release hole portion 14.
It is grasped so as to hold down with fingers from both of them. In this state, the upper root 22 is placed on the lower root 23 and the screw 2
1 through the hole 12 from above, and
And the upper root 22 and the lower root 23 are joined.

FIG. 3 shows a state where the screw 31 is gripped by the gripper 10 of the present invention. The hole 12 enables the driver to be simultaneously mounted on the application site from outside.

FIGS. 4 and 5 show an example of a work table according to the present invention. FIG. 4 shows a state where the dental implant component 48 is fixed. That is, the component 48 is fixed by the operation of pressing the operation unit 44 and releasing the pressing. Workbench upper part 41
Have holes 411, 412, 4 for fixing parts that penetrate vertically
13 are provided, and the workbench top 41 and the workbench bottom 4
A pressing plate 43 that rotates within a certain angle range by a rotation shaft 45 is disposed in the middle of the pressing plate 43. Holes 421, 422, and 423 for fixing the bottom parts are arranged in the worktable bottom 42 at substantially the same positions as the holes 411, 412, and 413 for fixing the parts, and have the same size. The work plate 43 is provided with component pressing holes 431, 432, and 433 that penetrate vertically, and when the work plate 43 is in the state of FIG.
It is provided at a position that matches the position and size of the component fixing holes 411, 412, and 413. Further, the work plate 43
Is in a state where a force is constantly applied outwardly by a spring 47 fixed by a fixture 46.

In use, the repulsive force of the spring 47 causes
As shown in (a), the work plate 43 is in a state of being pushed outward. The state is as shown in FIG. Next, when the operation unit 44 is pushed toward the worktable, the spring 47 is bent,
As shown in FIG. 5B, the component fixing hole and the component pressing hole are in a state of coincidence. With the operating portion 44 pressed, the implant component 48 is inserted into the communicating component fixing hole, the component pressing hole, and the bottom component fixing hole. Operation unit 4
When the work plate 43 is released, the work plate 43 tries to return to the state shown in FIG. 5A by the repulsive force of the spring 47, and pushes the implant part 48 in the middle in the outward direction. It is fixed in the state shown, and other operations are performed. Such a worktable can easily fix an implant part by pressing and releasing the operation unit, and thus effectively works for a simple operation at the time of surgery.

[0010]

As described in detail above, the present invention has a simple structure and is effective in assembling or disassembling an implant such as an artificial tooth root. When assembling a small part such as a two-piece type in a limited time such as in the oral cavity in a limited time, the present invention has an effect that a reasonable part can be gripped.
