Description

  The present invention relates to a compound extruder for forming impression and muscle pressure using a dental impression compound (hereinafter referred to as a compound), a muscle pressure generator for compound, and a compound extruder with a heater.

  In order to make a denture with good compatibility with the patient's oral cavity, it is necessary to obtain a marginal shape of the denture base that matches the movement of the patient's lips, cheeks and tongue. For this purpose, first, a rough impression is taken using a ready-made tray, and then the patient's own lower jaw, lips, cheeks, tongue movement, and massage of the lips and cheeks by the operator's fingers using a personal tray. By the operation, muscle pressure formation is performed to determine the boundary between the moving part and the non-moving part in the patient's mouth.

  This muscle pressure is formed using a compound. For example, as shown in FIG. 5, an alcohol torch 60 is used to moderately soften a bar-shaped compound 55 solidified into a bar shape having an outer diameter of about 8 mm, and adhere to the outer edge of the personal tray 50 as shown in FIG. After that, it is inserted into the patient's mouth and the above-described muscle pressure formation is performed. In general, since the series of operations described above takes time, it is performed several times for each part of the personal tray.

  In this way, muscle pressure formation is performed by inserting a personal tray on which the compound is attached and placed into the patient's mouth, so that the compound easily adheres to the personal tray and does not fall off. The shape in the oral cavity must be reproduced smoothly following the movement in the oral cavity of the patient, and the reproduced form must be fixed after muscle pressure formation.

  In other words, the compound must be fluid so that it remains fluid for a certain amount of time and maintains its fluid shape, and must solidify solidly after the formation of muscle pressure. In this way, the compound is different from the softened and fluidized state such as agar and paraffin wax in the softened state, and therefore, for example, the syringe disclosed in Patent Document 1 cannot be used. . On the other hand, since a compound is a solid material that is hard at room temperature, a stick-shaped material is convenient and inexpensive to supply and handle. For these reasons, the method and apparatus described above with reference to FIGS. 5 to 6 have been conventionally used for forming muscle pressure using a compound.

Patent No. 3013087

  However, in the formation of muscle pressure by the conventional method, it is not easy to uniformly soften a certain amount of the compound, and in particular, it is not easy to uniformly attach and arrange the compound on the personal tray. For this reason, there is a problem that the surgeon requires a very high skill and requires a long time for muscle pressure formation.

  In view of the conventional problems related to the present invention, in the formation of muscle pressure using a compound, a compound extruder that can quickly form muscle pressure without requiring a high level of skill from the operator, and formation of muscle pressure for the compound An object is to provide a compound extruder with an apparatus and a heater.

  The compound extruder according to the present invention comprises a cylinder filled with a compound for forming muscle pressure, and a piston that is inserted into the cylinder and pushes out the softened compound. A nozzle is provided.

In the above compound extruder, the nozzle may have an extrusion hole having a cross-sectional area of 15 to 150 mm ² through which the softened compound is extruded, and the cylinder should have a compound filling volume of 5 ml or more.

  In the above invention, by preparing a compound that can be suitably used for the compound extruder in advance, and by preparing in advance a compound extruder filled with such a compound, the muscle pressure forming operation can be made more efficient. Can be done automatically. Furthermore, the efficiency of the muscle pressure forming operation can be improved by providing a thermostatic bath that can keep the compound extruder filled with the compound in advance at an optimum temperature.

  In addition, the muscle pressure forming operation using the compound includes a cylinder filled with a compound for forming muscle pressure, a piston that is inserted into the cylinder and pushes out the softened compound, and the inside of the cylinder is heated to a predetermined temperature. Efficiently using a compound extruder with a heater having a main body composed of a heater for heating and a removal cap for filling the compound, and a nozzle for compound extrusion softened in the cylinder. be able to.

  The compound pusher according to the present invention can quickly generate muscle pressure without requiring high skill from the operator when forming muscle pressure using the compound. And the muscle pressure formation operation | work can be efficiently performed by using the compound muscle pressure forming apparatus which concerns on this invention, and the compound extruder with a heater.

  An embodiment of a compound extruder according to the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of a compound extruder according to the present invention. FIG. 1 is a perspective view showing the entire compound extruder, and FIG. 2 is an enlarged view showing a shape of an extrusion hole into which a softened compound is extruded. FIG.

  As shown in FIG. 1, the present compound extruder 10 has a cylinder 11 filled with the compound, and a piston 13 which is inserted into the cylinder and pushes out the softened compound. Nozzle 12 is provided. The compound is extruded from the extrusion hole 15 of the nozzle 12. A cap 18 can be provided for dust prevention or the like.

  Known cylinders and pistons 13 can be used. For example, a cylinder or piston made of a known synthetic resin, glass or metal such as stainless steel can be used.

  As described above, the compound extruder 10 according to the present invention includes the nozzle 12 that can push out the softened compound moderately and smoothly so that the work of attaching and placing the compound on the personal tray can be smoothly performed. That is, it has a nozzle 12 having an inner diameter that is smaller than the inner diameter of the cylinder 11 but considerably larger than the conventional one, and an extrusion hole 15 provided in the nozzle 12.

The degree of the cross-sectional area of the extrusion hole 15 is important. In order to extrude the softened compound moderately and smoothly, the cross-sectional area of the extrusion hole 15 is preferably 15 to 150 mm ² . If the cross-sectional area of the extrusion hole 15 is 15 mm ² or less, the compound cannot be easily extruded. On the other hand, when the cross-sectional area of the extrusion hole 15 exceeds 150 mm ² , it is difficult to adjust the amount of the compound attached to the personal tray as necessary because it is extruded in a large amount.

  The shape of the extrusion hole 15 is not particularly limited. As shown in FIG. 2, the circular cross-sectional shape shown in FIGS. 2A and 2B or the drop-like cross-sectional shape shown in FIG. Moreover, it can also be set as a star-shaped cross-sectional shape, Furthermore, another form can also be employ | adopted as needed. However, the rectangular cross-sectional shape shown in FIG. 1 has an advantage that the adhesion area of the compound adhered to the personal tray can be easily adjusted.

  In the present invention, the cylinder 11 preferably has an internal volume capable of being filled with 5 to 10 ml of compound. This amount is an amount that can be filled with at least one or two conventional bar-shaped compounds, can prevent a temperature drop while the compound is attached to a personal tray, and also creates muscle pressure. A sufficient amount can be secured. Note that the upper limit of the internal volume of the cylinder 11 is not necessarily limited to 10 ml. What is necessary is just to determine according to the quantity required for muscle pressure formation, work amount, etc.

  The compound extruder 10 has been described above. However, the compound extruder according to the present invention is not limited to the above embodiment. For example, in FIG. 1, the nozzle 12 is formed integrally with the cylinder 11, but the nozzle 12 and the cylinder 11 can be screwed together to be integrally connected. In this case, there is an advantage that the nozzle according to workability can be replaced and used.

  Moreover, this invention can make a muscle pressure formation operation | work still easier by the instrument and apparatus using the said compound extruder. That is, as described above, the compound extruder 10 can be filled with one or more conventional bar-shaped compounds, thereby improving the efficiency of the muscle pressure forming operation. For this reason, in a factory or the like that produces the product according to the invention, a compound suitable for the compound extruder is manufactured, and a compound extruder filled with the compound is manufactured, and a packaging process is performed. It will be shipped after commercialization. In this case, the shape of the compound is preferably a rod having an outer diameter of 12 to 16 mm and a length of 60 to 100 mm.

  Furthermore, in a dental treatment site such as a dental clinic, the compound extruder 10 is filled so that the compound can be softened and used immediately in the muscle pressure forming operation using the compound extruder 10. It is preferable to prepare in advance a thermostatic chamber for heating the compound. Thereby, the muscle pressure forming operation can be performed more efficiently. Since the softening point of the compound is generally 50 to 60 °, the constant temperature bath may be anything that can be heated to a temperature higher than the softening point of the compound and controlled to a predetermined temperature. The compound extruder filled with the compound can be subjected to muscle pressure forming work after being immersed in hot water at 98 ° C. for about 2 minutes.
