Description

Impact tool for the production of dental supplements}

The present invention relates to an impact tool for dental laboratories, and more particularly, to eliminate the problems of conventional work as one of the processing tools used in dental laboratories, and greatly increase the workability of dental laboratories. The present invention relates to the provision of an impact tool for maintaining the precision of a workpiece.

In dental laboratories and dental hospitals, artificial teeth are formed by molding thermoplastic resins, paraffins, etc. in the same shape as teeth of the patient's treatment for the purpose of orthodontic treatment, dental treatment, and implantation. First, the teeth of precise shape should be made of thermoplastic resin or paraffin in the same way as the shape of the natural teeth and dental procedures of the patient.

For this purpose, a pin hole is formed in a mandibular or maxillary model to allow partial insertion and fixation of the tooth in a typical dentition state. After performing the operation, the work is removed from the pinhole, molded with plaster or the like, or artificial teeth are made by the lost wax technique.

In the conventional dental laboratory work as shown in Figs. 1 and 2,

On the artificial orthodontic shape (A) modeled after the mandible or maxillary shape, the tooth (T) is processed with paraffin or thermoplastic resin, etc., in order to form a plaster mold of the processed tooth (T) to be treated, and the mold is removed by lifting the mold. .

As shown in Figure 2, on the artificial dental implant (A) in the above-described dental work,

The shape of the tooth (T) which is fixed to the corresponding dental portion by the fixing pin (P) and the fixing hole (H) to be separated is processed into paraffin, gypsum, resin and the like.

In this process, the fixing pin (P) of the processed tooth (T), which is fitted into the fixing hole (H) of the artificial orthodontic article (A), which is a mandibular or upper jaw model, is introduced into the impurities, the side teeth and It does not fall easily after the end of processing due to the fitting, deformation and hardening of the workpiece.

Therefore, in the past, the end of the fixing hole (H) as a sharp hand tool is pushed in the direction of the arrow or by applying a light impact to achieve the separation, this separation operation impacts the entire artificial dental feature (A) or processed tooth ( It had a problem of causing deformation of the processed tooth T which was hard and hard by applying the impact to the side of T).

Therefore, a great deal of attention was required for the departure work, and in some cases, rework was required.

In view of the above-mentioned problems, the dental tool of the present invention makes the dental implant work extremely easy to dislodge from the artificial teeth (A) of the processed tooth (T) and minimizes the deformation of the processed tooth (T). An object of the present invention is to provide a tool of various configurations, such as increasing the efficiency of the program.

It is characterized by making it cost on the pin side.

Another feature of the dental tool for impact of the present invention;

The slide connection between the cylinder inner wall of the return cylinder and the piston acts as an elastic body and instantaneously has a modulus of elasticity higher than that of the impact spring.

The construction and operation of the dental stomatological impact tool of the present invention together with the accompanying drawings will be described in more detail.

Figure 3 is a cross-sectional view of the overall assembly configuration of the dental tool for dental impact tool of the present invention, Figure 4 is a cross-sectional explanatory view showing a disassembled state of the component of the dental tool for dental impact of the present invention.

The dental tool impact tool 100 of the present invention is characterized in that the principle of applying the action that the compressive force due to the pressurization is instantaneously changed to the impact.

It is constituted as a rough tubular driver shape and is separated and configured as a piston pipe body 20 constituting the entire pipe body in cooperation with the main cylinder pipe body 1 and the main cylinder pipe body 1,

The main cylinder pipe body 1 and the piston pipe body 20 are assembled by threaded coupling or interference fitting, or the like, to form one pipe casing.

The front of the main cylinder tube (1) is open, the locking jaw (1 ') protrudes in a ring shape inward, and the rear end is a tubular body having a closed block (1 ").

In addition, the rear end portion of the main cylinder pipe (1), the grip 50 of various shapes and materials for smooth gripping and pressing action is fitted, fixed.

An impact spring 2 is inserted between the closed portion 1 "at the rear end of the main cylinder pipe 1 and the return cylinder 10 slidably inserted into the main cylinder pipe 1.

The piston 30 is also slidably inserted into the cylinder inner wall 10 'of the return cylinder 10, and the return spring 22 retained in the engaging jaw 30' of the piston 30 is the piston 30. The other end is sandwiched between the engaging jaw (1 ') of the main cylinder pipe (1) in the state fitted to the.

The cylinder inner wall 10 'of the return cylinder 10 and the connection portion of the piston 30 are preferably machined precisely so as to fit tightly, and the interval is configured to such an extent that the operation described later can be guaranteed.

In addition, the elastic modulus k1 of the impact spring 2 should be relatively larger than the elastic modulus k2 of the return spring 22, and the reason thereof will be described later.

The piston 30 is housed in the main cylinder pipe 1 by threaded coupling of the piston pipe body 20, and is in contact with the impact pin 60 at its end, and the impact pin 60 is reduced in the piston pipe body 20. It penetrates inside the diameter part 20 ', and the slide movement is possible.

The main operation of the dental instrument impact tool 100 of the present invention is carried out by a series of operations of the impact spring 2, the return spring 22, the return cylinder 10 and the operation will be described below.

Impact tool for dental technicians of the present invention from below of FIG. 2 with respect to the fixing pin (P) of the processed tooth (T) that the worker is fitted in the fixing hole (H) of the artificial teeth (A) of the mandible or upper jaw ( Put the impact pin 60 of 100) and press the entire impact tool 100.

Then, the entire impact tool 100 is pressed downwards, and at the same time, the impact spring 2 and the return spring 22 inside the main cylinder pipe 1 and the piston pipe 20 are pressed together, and the piston into the return cylinder 10 inside. (30) advances.

However, since air is drawn into the inner space portion of the return cylinder 10, the entry of the piston 30 in the cylinder inner wall 10 ′ is initially entered to a state of being shot while being suppressed to some extent.

In this state, when the impact tool 100 is pressed further, the entry of the piston 30 on the cylinder inner wall 10 'of the return cylinder 10 is made rapidly after passing the critical point.

In this state, the impact spring 2 is already sufficiently compressed, and in the state where the return cylinder 10 and the piston 30 are fully entered, the resistance is abruptly moved forward by the elasticity of the impact spring 2. Done.

therefore. The piston 30 is momentarily moved forward to hit the rear end of the impact pin (60). Then, the momentary impact is applied to the impact pin 60 while being hit by the rear end of the fixing pin (P) of the tooth (T) is easily separated.

After this series of operations, all parts are returned to their original stretched state by the operation of the return spring 22 and the operation of the impact spring 2.

Accordingly, the slide connection between the cylinder inner wall of the return cylinder 10 and the piston 30 acts as an elastic body such as a kind of absorber spring and instantaneously has an elastic modulus higher than the elastic modulus k1 of the impact spring 10. Although the impact spring 10 is initially compressed as a result, the impact force of the impact spring 10 is momentarily released when the impact force of the cylinder inner wall of the return cylinder 10 and the slide connection of the piston 30 is removed. It will work as a blow force.

Therefore, in order for the above operation to be smooth, the connection between the return cylinder 10 and the piston 30 must be maintained in a very close connection, and the processing is performed such that the air is gradually discharged from the inner space of the return cylinder 10.

Dental tool for impact of the present invention as described above; Compared to the method of detaching the processed tooth (T) as a conventional hand tool, the impact is applied to the fixing pin by only pressing lightly, so that the removal of the processed tooth (T) is instantaneously and the deformation of the processed tooth (T) is minimized. Has usefulness.
