  FIG. 4 is a side view showing an embodiment of a conventional dental clinical / technical working apparatus, which includes a syringe 6, a metal stand 7, and a heating device 8.

  As shown in FIG. 5, the syringe 6 is composed of a cylinder body 9 for extruding and a piston 10 inserted into the cylinder body 9, and the cylinder body 9 has a gap in the outer periphery of an inner tube 11 formed of pure copper as a metal having good thermal conductivity. 12, a heat insulating outer tube 13 is provided, and a pure copper tip lid 14 having a nozzle-like spout at the tip of the inner tube 11 exiting from the heat insulating outer tube 13 is provided. The finger ring body 15 having a flange 15b for finger hook projecting outwardly and integrally was fitted to the root end. Reference numeral 10a denotes a piston handle.

  A cap body 17 that accommodates the spout is fitted into the distal end lid body 14. The cap body 17 is also made of pure copper as a metal having good thermal conductivity. Further, the metal stand 7 is also made of pure copper as a metal having good thermal conductivity, and the concave portion 7a into which the cap body 17 or the tip lid body 14 as the tip of the cylinder body 9 is inserted is formed as an upper surface opening.

  As shown in FIG. 4, the heating device 8 is provided with a rectangular metal hot plate 18 formed of pure copper or pure aluminum as a metal having good thermal conductivity on a main body in which an energization control mechanism, a timer, and the like are incorporated. A heater 19 was partially attached to the back surface of the metal hot plate 18. Further, a temperature sensor 20 such as a thermistor is attached to the back surface of the metal hot plate 18 at a distance from the heater 19. In addition, 21 is a power cord and 22 is a temperature adjustment knob.

  Next, the usage will be described. The metal stand 7 is placed on the surface of the metal hot plate 18 of the heating device 8 so as to be movable while holding the syringe 6 in an upright state.

  At that time, the syringe 6 is filled with dental material such as agar or paraffin wax in the cylinder body 9, and a cap body 17 is fitted at the tip.

  In this way, the heater 19 is heated to heat the metal hot plate 18, and the heat from the metal hot plate 18 is transferred to the cylinder body 9 through the metal stand 7, the cap body 17, and the tip lid body 14. The dental material of the cylinder body 9 is heated by transmitting to the inner tube 11 and heating the inner tube 11. In that case, since all are formed with the metal with good heat conductivity, it becomes efficient heating.

  When filling the cylinder body 9 with paraffin wax or the like, the cylinder body 9 is filled with a cylinder-shaped product, but the temperature to be obtained may be about 60 degrees, so that the metal hot plate 18 is used from the beginning. The metal stand 7 is installed at a location away from directly above the heater 19 on the surface.

  However, in order to warm the syringe quickly and make it difficult to cool during use, if the cylinder body has a double structure consisting of a metal inner tube with good thermal conductivity and a heat insulating outer tube, the structure of the syringe becomes complicated and the weight increases. The operability of the syringe will be reduced.

  Further, when the cylinder body has a double structure, when a dental material melted in the gap between the inner tube and the outer tube enters, it is not easy to take it out and it is difficult to care for it. However, if the cylinder body is made of only a metal having good thermal conductivity, the internal dental material will quickly cool and harden during use of the cylinder.

  Therefore, a dental clinical / technical work implement that is lightweight and has good operability while ensuring heat retention during use of the syringe is desired.

  In addition, when the syringe is set up on a metal stand, the syringe is supported only by the spout of the tip lid, so a method that can warm the syringe in a more stable state on the hot plate is desired. .

  In addition, paraffin wax, which is one of the dental materials to be filled in syringes, is generally marketed in the form of plates or lumps. Conventionally, these must be peeled or melted and then placed directly on the dental model. It was a troublesome task.

  Therefore, it is desired to make it possible to fill the syringe efficiently and easily even in the case of plate-like, lump-like, or unusable dental material.

The cap body 17 is also made of polysulfone, and the inner periphery of the recess 17a that accommodates the spout port 14a and the outer periphery of the spout port 14a are threaded with each other. Fits in a screwed state. In addition, a packing 17b is disposed on the inner bottom surface of the recess 17a in order to improve airtightness.

  The piston 10 is formed of a synthetic resin such as nylon and has a handle 10a at the end. Reference numeral 10b denotes an O-ring for enhancing airtightness, and is fitted in a circumferential groove at the tip of the piston 10.

  The metal stand 7 is composed of a pedestal 27 and a cylindrical member 26, both of which are made of anodized aluminum as a metal having good thermal conductivity. The pedestal 27 is formed with a concave portion 27a into which the cap body 17 or the tip lid body 14 at the tip of the cylinder body 9 is inserted as an upper surface opening. On the other hand, the cylindrical member 26 is formed in a cylindrical shape having an outer diameter of 25 mm equal to the inner diameter of the concave portion 27 a, and the lower end of the cylindrical member 26 is press-fitted into the concave portion 27 a of the base portion 27 to form the metal stand 7. Further, the cylindrical member 26 is provided with a heat insulating portion 28 made of a thermosetting resin on the upper outer peripheral surface.

  Here, while the thickness of the cylindrical member 26 is 2 mm, the thickness of the base portion 27 is 7.5 mm, so that the base portion 27 serves as a weight in the metal stand 7, and the metal portion 7 is made of metal. The center of gravity of the stand 7 is lowered so that the vertically long metal stand 7 can be stabilized in an upright state.

In the present embodiment, the concave portion 27a is a watertight concave portion having the bottom surface 7b. However, as another embodiment, the concave portion 27a may be vertically penetrated.

  As shown in FIG. 4, the heating device 8 is provided with a rectangular metal hot plate 18 formed of pure copper or pure aluminum as a metal having good thermal conductivity on a main body in which an energization control mechanism, a timer, and the like are incorporated. A heater 19 was partially attached to the back surface of the metal hot plate 18. Further, a temperature sensor 20 such as a thermistor is attached to the back surface of the metal hot plate 18 at a distance from the heater 19. In addition, 21 is a power cord and 22 is a temperature adjustment knob.

  Next, the dental material mold of the present invention will be described as a dental material mold for shaping the dental material so as to be suitable for filling the cylinder body 9 of the syringe 6 as such a dental clinical / technical work tool.

  As shown in FIG. 2, which is an overall perspective view showing an embodiment of a dental material mold according to the present invention, the dental material mold includes a columnar member 30 and a sheet having a slightly larger area than the bottom surface of the columnar member 30. Both members are formed of flexible silicone rubber having a high degree of peeling, which is an elastic material.

  The columnar member 30 has a height from the bottom surface to the upper surface 33 of 62 mm, which is shorter than the length of the body 40 of the cylinder body 9 of the syringe 6, and a dental material inflow space 31 that opens from the upper surface 33 to the bottom surface, A plurality of 32 are provided. An edge 34 protruding 2 mm above the upper surface 33 is provided around the upper surface 33.

  The dental material inflow space 31 has a cylindrical shape, and its diameter is 13 mm, which is equal to the inner diameter of the body 40 of the cylinder body 9 of the syringe 6. 32 is a dental material inflow space, which has a diameter of 8 mm and is suitable for shaping a dental material used for a syringe having an inner diameter of 8 mm.

  Next, a method for preparing the dental material before use using these dental material molds and a method for using the dental clinical / technical work implement will be described.

  First, plate-shaped or unused bulk paraffin wax or the like is put in a medicine can and heated on a stove or hot plate to be completely melted. Next, as shown in FIG. 3, paraffin wax or the like 37 is poured from the medicine can 36 into the dental material inflow spaces 31 and 32. Since the sheet member 35 is laid on the bottom surface of the dental material columnar member 30, the work space 38 such as a desk is not damaged by the molten paraffin wax 37 or the like. Further, since both the columnar member 30 and the sheet member 35 are formed of silicone rubber, which is an elastic material, the bottom surface of the columnar member 30 is closely adhered to the sheet member 35, and paraffin wax 37 leaks from below. There is no end to it.

  Further, since the edge 34 exists on the outer periphery of the upper surface 33 of the columnar member 30, even if the paraffin wax 37 overflows from the inflow spaces 31, 32 of the dental material, it is dammed up by the edge 34 and further overflows from the upper surface 33. It won't get dirty.

  When the paraffin wax 37 is cooled and hardened, the columnar member 30 is removed from the sheet member 35, and the paraffin wax 37 is extruded from the bottom side. Note that the paraffin wax and the like 37 protruding on the upper surface 33 is scraped off with a knife or the like. Since there are a plurality of dental material inflow spaces 31, 32, a plurality of paraffin wax columns can be molded together at a time, which is efficient.

  The syringe 6 is filled with a solid paraffin wax 37 or the like. Since the paraffin wax 37 is formed in the same cylindrical shape as the inside of the body 40 of the cylinder body 9 of the syringe 6 along the shape of the dental material inflow spaces 31 and 32, the syringe 6 can be filled without any gaps. Efficient.

Next, the spout 14a tip fitted with a cap member 17, a spout 14a side down to insert the syringe 6 to the metal stand 7. And in a conventional manner by placing a metal stand 7 partially arranged a heater metallic hot plate, heat the metal stand 7 with the temperature adjusted by the distance from the heater. The metal stand 7 is placed on the surface of the hot plate 18 so as to be movable while holding the syringe 6 in an upright state, and warms quickly because it is made of aluminum with good thermal conductivity. Further, since the metal stand 7 is a case-like housing the cylinder body 9 into the cylindrical member 26, the entire cylinder body 9 by a metal stand 7 is covered, the heat of the hot plate is transmitted efficiently syringe 6.

Since the metal stand 7 has a low center of gravity, inserting the syringe 6 can be stably held on a hot plate. Further, the metal stand 7 because it has a case-like housing the syringe 6 by the cylindrical member 26, excellent stability as compared with the case where as in the prior art supporting the syringe 6 with only its distal end.

Note that when the hot plate is made of iron, by attaching a magnet to the bottom surface of the metal stand 7, or, it is possible to prevent the overturning of effectively metallic stand 7 by the base portion 27 and the magnet I can do it. Moreover, although the example of aluminum as a metal with good thermal conductivity has been described in the above embodiment, it can be replaced with another metal with good thermal conductivity such as pure copper.

  The temperature of the heater 19 of the hot plate can be adjusted by the temperature adjusting knob 22, but the temperature on the surface of the metal hot plate 18 varies depending on the distance from the heater 19. The temperature obtained by the difference between the portion directly above the heater 19 and the portion away from the portion directly above the heater 19 can be made different.

  When not in use for a while, such as at night, the upper portion of the metal hot plate 18 of the heating device 8 may be covered with a cover 25 made of synthetic resin to prevent useless heat dissipation.

  When the syringe 6 is sufficiently warmed and the paraffin wax 37 in the syringe 6 becomes soft, the syringe 6 is taken out from the metal stand 7, the cap body 17 is removed, the piston 10 is pressed, and the paraffin wax 37 is removed from the spout 14a. Extrude.

  For example, as shown in FIG. 6, in creating the dental model 41, the gingival part 41 a can be formed with paraffin wax 37 or the like by pressing and placing the paraffin wax 37 from the syringe 6.

At this time, since the cylinder body 9 is formed of polysulfone, which is a heat insulating material, the paraffin wax 37 inside is difficult to cool and can be prevented from easily solidifying during use. Further, since the syringe 6 is made of a resin having a single layer structure, it is lightweight and has good operability.
