Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a capsule for a tooth restorative material that is used when a tooth restorative material consisting of two components, powder and liquid, is used for filling, bonding, backing, filling, and other types of tooth restoration.

[Prior Art 1] To repair a tooth cavity, a tooth restorative material is generally filled. As such tooth restoration materials, two-component materials that easily react when mixed are usually used. These two-component materials often consist of a combination of powder and liquid, each of which is supplied to the market in glass or plastic bottles. Since such a two-component material rapidly undergoes a hardening reaction after being mixed, it is necessary to fill the tooth cavity as quickly as possible before it hardens. The operation of measuring the above-mentioned bottled materials just before filling and mixing them with a spatula etc. is complicated and time-consuming, so in recent years capsules containing a certain amount of powder and liquid in a separated state have become commercially available. This is no longer necessary, and mixing and kneading after combining the two components can now be done in a few seconds by applying mechanical vibration to the capsule. [Problems to be Solved by the Invention] However, even if a capsule containing a predetermined amount of tooth restoration material as described above is used, the contents mixed in this way cannot be removed from the capsule. It takes time to take out the material into a separate container and then fill it into the tooth cavity.Especially when the temperature is high, the curing reaction of the mixed and kneaded tooth restorative material becomes faster, so it may harden considerably during filling. The problem was that there were many failures as progress was made.

[Means to solve the problem]

The inventors of the present invention made various studies to solve the above problems, and as a result, they found a bond in which the tooth restoration material inside the capsule was mixed. We have developed a syringe for dental restoration materials for extruding capsule contents that can be extruded more quickly than a nozzle installed at the tip of a capsule, and does not obstruct gazing at the restoration position in a narrow oral cavity and does not give a feeling of pressure when thinking. Jitsugan 1986
- Proposed in No. 201319. With the development of such a syringe for tooth restorative materials, it has become possible to quickly fill the tooth restoration area with the mixed and kneaded tooth restorative material in the capsule for tooth restorative materials. Among the tooth restorative materials that are stored in isolation in the capsule, the pack containing the liquid tooth restorative material is placed in advance in the capsule. The problem is how to mix the tooth restoration material liquid with the tooth restoration material powder from this pack so that it can be supplied to the tooth restoration part. In the case of a capsule consisting of a dental preparation mixing container with a structure like the one described above, the pressure rupture pack containing the tooth restoration material liquid inside is located on the side of the cylinder, so the cylinder This requires a complicated shape in that a mounting part for a clip to hold the pack must be provided on the side of the cylinder, and the presence of this clip unnecessarily increases the diameter of the capsule. The disadvantage of this method is that it requires a bottle to prevent the kneaded and mixed tooth restorative material from flowing out, making it cumbersome to operate. If a pack for pressure bursting, one side of which is made of a weak material, is placed between the frontage of the cylinder tip and the nozzle, a clip can be attached to the side of the cylinder as in Utility Model Publication No. 55-46625. The present invention was developed based on the findings that there is no need to provide a pressure rupture pack, and that the mixed and kneaded tooth restoration material will not flow out from the nozzle unless both of the two sheets constituting the pressure rupture pack are damaged. In other words, the present invention has a cylinder which has a predetermined amount of powdered tooth restoration material stored therein and an extrusion plunger fitted at the rear end of the cylinder. A tooth restoration material capsule that holds a pressure rupture pack that contains a tooth restoration material liquid inside and is made of a weak material on the cylinder side, and is equipped with a pack holder that has a nozzle at the tip. When the extrusion plunger is moved toward the pack holder to a position close to the opening at the tip of the cylinder, the flange compresses the elastic body on the pack holder and moves, thereby causing the flange to move. A tooth restoration material, characterized in that a pack-piercing body is inserted in which a cylindrical piercing part provided at the center of the section penetrates the opening and breaks through the pack holder side of the pressure-rupturing pack. It provides capsules.

The figure is a perspective view of the pack-piercing body, and FIG. 6 is a side sectional view corresponding to FIG. 1 showing another embodiment of the tooth restoration material capsule according to the present invention. In the drawings, reference numeral 1 indicates a capsule for a tooth restorative material according to the present invention. 2 stores a predetermined amount of tooth restoration material powder A inside, has an extrusion plunger 2a fitted at the rear end, and has an opening 2 at the tip opposite to the extrusion plunger 2a.
btf, has a recess 2c on its outer periphery for engagement with a syringe (not shown) for extruding tooth restoration material, and is further provided with a male screw 2d on the outer periphery of its tip, and its inner periphery The extrusion plunger may have a key-shaped guide for regulating the direction of movement of the extrusion plunger. The mouth cylinder 2 is preferably made of a transparent or semi-transparent material such as plastic glaze so that the tooth restoration material stored therein is easily exposed, especially if it is accidentally dropped or transported. Preferably, it is made of plastic that is hard to damage inside. 3 is located further toward the tip of the opening 2b at the tip of the cylinder 2. Liquid B, which is a tooth restoration material, is stored inside, and the cylinder 2 side is made of a weak material such as aluminum foil, and the opposite side from the cylinder 2 is made of plastic. This suppressed rupture pack is made of a material stronger than the weaker material, such as coated aluminum foil. Reference numeral 4 denotes a pack holder having a nozzle 4a at its tip for holding a pack for pressure bursting with the cylinder 2 side made of a weaker material on the further tip side of the opening 2a at the tip of the cylinder 2, and this pack holder. A female screw 4b is provided on the cylinder 2 side of 4 and is screwed onto the outer periphery of the cylinder 2, and by rotating the pack holder 4 and moving it toward the cylinder 2 side, the suppressed rupture pack is ruptured under pressure. However, since it is engaged with the outer periphery of the cylinder 2, the pack holder 4 cannot be rotated by the hand press (
A pack for pressure bursting may be caused to burst by moving it toward the cylinder 2 side. The nozzle 4a of this pack holder 4 is arranged in two cases: one in which the center line of the nozzle 4a at the tip of the pack holder 4 is parallel to the central axis of the cylinder 2 as shown in FIGS. The center line of the nozzle 4a at the tip of 4 is the cylinder 2
In addition, the tip of the nozzle 4a at the tip of the pack holder 4 may be open from the beginning, or the tip may be opened by cutting it off during use. In the former case, the nozzle 4a may be equipped with a bottle or a lid-like body that connects the opening end of the nozzle 4a to prevent foreign matter from entering, and in the latter case, the resection position is indicated. Mark marks such as the recessed line with the nozzle 4 in advance.
It may be provided on the outer periphery of the tip of a. Reference numeral 5 denotes an elastic body made of a spring or sponge that is attached around the opening 2b at the tip of the cylinder 2, and 6 is an extrusion plan that is attached near the opening 2b at the tip of the cylinder 2. When the jar 2a is moved toward the pack holder 4 side, the flange portion 6a compresses the elastic body 5 on the pack holder 4 side and moves, resulting in a 7-lunge aB6a.
A cylindrical piercing portion 6b provided in the center is a pack piercing body that penetrates the pack holder 4 side of the pressure bursting pack 3 through the four openings 2b of the cylinder 2, and the cylinder of this pack piercing body 6 Does the tip of the pierced portion 6b have a closed profile cross-sectional shape so that the pierced portion of the pressure rupture pack 3 is not cut off and leaked into the nozzle 4a of the pack holder 4? Alternatively, it is preferable that the tip of the cylindrical body be cut obliquely. 1. Effect] Next, a method of using the capsule for tooth restoration material according to the present invention having the above-described structure will be described. First, the female thread 4b of the pack holder 4 is screwed into the male thread 2d of the cylinder 20 of the tooth restoration material capsule 1 according to the present invention in the state shown in FIG. As shown in Fig. 2, the weak material portion on the cylinder 2 side of the pressure rupture pack 3 is ruptured, or the cylinder 2 of the tooth restoration material capsule 1 and the pack holder 4 are engaged without screws. In this case, the pack holder 4 is moved to the cylinder 2 side using a hand press, and the pressure rupture pack 3 is pressed to rupture the weak material portion of the pressure rupture pack 3 on the cylinder 2 side. The liquid B of the tooth restoration material inside is made to flow into the cylinder 2 from the opening 2b of the cylinder 2. Immediately after the tooth restoration material liquid B flows into cylinder 2, set it in a special mixer and remove it from cylinder 2.
Mix and knead the tooth restoration material powder that was previously stored inside. After mixing and kneading the powder A of the tooth restorative material and the liquid B of the tooth restorative material in this way, the engaging recess 2c of the capsule 1 for a tooth restorative material according to the present invention is immediately connected to the syringe for a tooth restorative material. The plunger 2a for extruding the cylinder 2 of the capsule for tooth restorative material according to the present invention is fitted together with the extruder rod of the syringe for tooth restorative material.
When the tooth restoration material is pushed out toward the tip side, the tooth restoration material, in which the powder of the tooth restoration material and the liquid B of the tooth restoration material are mixed and kneaded by the extrusion plunger 2a, pierces the pack through the flange portion 6a of the body 6 due to the pressing force. moves by compressing the elastic body 5 on the side of the pack holder 4, and the cylindrical piercing part 6b provided at the center of the flange part 6a penetrates the opening 2b of the cylinder 2 and releases the pack 3 for pressure bursting. When the cylinder 2 on the non-ruptured side and the strong member on the opposite side are pierced, the kneaded and mixed tooth restoration material passes through the cylindrical pierced part 6b of the pack piercer 6 and enters the nozzle 4 of the pack holder 4.
It begins to flow into a. In such an operation, if the tip of the nozzle 4a of the pack holder 4 is closed in advance or the open end is IW1 chained with a bottle or a lid-like body, in order to open the tip of the nozzle 4a, By cutting off the obstructed part at the tip of the nozzle 4a or removing the bottle or lid-like body, the tip of the nozzle 4a can be pushed out and filled into the cavity of the tooth to be repaired. Effect 1 of the invention The syringe for tooth restoration material according to the present invention as described above is used because the powder A of the tooth restoration material and the liquid B of the tooth restoration material are stored in a state where they are separated by a predetermined amount in advance. There is no need for the operator to measure the amount each time it is used, and since the pressure bursting pack 3, which contains the tooth restoration material liquid B, is positioned at the tip of the cylinder 2, the diameter of the cylinder 2 can be adjusted to 55-46625. In order to prevent the tooth restoration material from becoming too large, the tooth restoration material capsule according to the present invention is attached to a tooth restoration material syringe and inserted into the oral cavity to fill the tooth cavity with the tooth restoration material. It does not get in the way of viewing the state of the tooth restoration material, and it also prevents the phenomenon that the mixed tooth restoration material flows out from the nozzle at the tip of the tooth restoration material capsule when mixing and kneading the tooth restoration material. It has various advantages, such as the fact that it is not used in the field of dentistry, and it is an extremely important contribution to the field of dentistry.
