  FIG. 1 is a diagram for explaining the first embodiment, and is an exploded perspective view showing the technical equipment holding device 100, the crown technical equipment 1, and the bridge technical equipment 2 together.

On the side of the bridge technical material 2 where the polymerization material is not disposed, a concave portion (not shown) is provided so that one end of a post for technical polymerization polymerization 10 described later can be inserted.

  Hereinafter, the crown technical material 1 and the bridge technical material 2 may be collectively referred to as dental prosthesis technical materials 1 and 2.

  The technical-polymer polymerization holding device 100 includes a technical-polymer polymerization stand 3, a pin 4, and a technical-polymer polymerization post 10.

The technical product polymerization stand 3 is a member that functions as a pedestal for holding the pins 4 and the technical product polymerization post 10 in an upright posture, and includes a cylindrical main body 3a as a whole. The main body 3a is provided with a plurality of holes 3b extending from the upper end surface toward the lower end surface. The hole 3b is configured so that the pin 4 can be erected by inserting one end side of the pin 4.
As such a technical product polymerization stand, a known one can be used, and its form is not particularly limited.

  The pin 4 is a rod-shaped metal member, and one end of the pin 4 is configured to be inserted into the hole 3 b of the technical product polymerization stand 3. Such a pin 4 can be a known pin as described above.

  When the polymerization material contained in the dental prosthesis technical materials 1 and 2 is cured in the polymerization device, the technical material polymerization post 10 stabilizes the dental prosthesis technical materials 1 and 2 in the polymerization device. It is a member to hold. FIG. 2 is an enlarged view of the post 10 for polymerizing a technical product. FIG. 2 shows a state in which the pins 4 are inserted into the technical product polymerization post 10. The lower part of FIG. 2 is a front view, and the upper part of FIG. 2 is an explanatory diagram corresponding to the plan view.

  As can be seen from FIGS. 1 and 2, the technical product polymerization post 10 has a columnar base 11, and a plurality of projecting portions 12 are provided so as to project from one end surface of the base 11. In the present embodiment, the four protruding portions 12 are arranged so as to be arranged along the outer peripheral portion of the circular end surface of the base portion 11.

  The base portion 11 functions as a base material portion for forming the protruding portion 12. Therefore, the shape of the base 11 is not particularly limited as long as it has such a function. For example, although the base 11 of this embodiment is a form in which two cylinders having different diameters are arranged coaxially, the base 11 is not limited to this, and may be a base having a constant diameter. Moreover, it does not need to be a cylinder and may be a polygonal column.

  The base 11 is provided with a hole (not shown) so that one end side of the pin 4 can be inserted into the end surface opposite to the end surface where the protruding portion 12 is provided. As a result, as shown in FIG. 2, the technical product polymerization post 10 and the pin 4 can be integrated. The hole may or may not penetrate through the base 11.

  The material which comprises the base 11 is not specifically limited. However, in consideration of the moldability of the entire technical product polymerization post 10, it is preferable that the material is the same as the protruding portion 12 described later.

  The protrusions 12 are a plurality of members provided so as to protrude from one end surface of the base 11. In the present embodiment, the four protruding portions 12 are arranged so as to be arranged along the outer peripheral portion of the circular end surface of the base portion 11.

The protrusion 12 is made of a soft material and is rich in elasticity. Thereby, when inserting and arrange | positioning the several protrusion part 12 with respect to the recessed part of the dental prosthesis technical products 1 and 2, it can deform | transform and insert so that the front-end | tip of the some protrusion part 12 may mutually approach. Then, the plurality of protrusions 12 are spread in the recesses of the dental prosthesis technical materials 1 and 2 to urge the wall surfaces of the recesses, thereby stably and strongly holding the dental prosthesis technical materials 1 and 2. It becomes possible.
Further, the protrusion 12 is made of a soft material, so that the dental prosthesis technical materials 1 and 2 are hardly damaged and can be used repeatedly.

Thus, the protrusion 12 should just be able to deform | transform within the elastic range which can be urged | biased so that the some protrusion 12 may expand within the recessed part of the dental prosthesis technical products 1 and 2. FIG. Specifically, the protrusion 12 is preferably a rubber, resin, or elastomer having a Young's modulus of 5 GPa or less. Examples of the material for that purpose include silicone, nitrile rubber, fluororubber, polypropylene, polyethylene terephthalate, polycarbonate, polyamide, and fluororesin. Moreover, in order to improve elasticity, heat resistance, impact resistance, etc., a material containing glass fiber or the like in a resin, or a material in which two or more kinds of resins are mixed may be used.
The Young's modulus is preferably 1 MPa or more. If the Young's modulus is smaller than this, it is too soft to hold the dental prosthetic materials 1 and 2 and may be deformed by vibration and easily come off. Further, such a material is highly likely to be a material containing air such as a foamed polymer, and is considered not suitable as a material to be applied.

  Here, by using silicone for the projecting portion 12 or increasing the heat-resistant temperature by other means, the technical product polymerization post 10 can be placed in the heating polymerization vessel. That is, it can also be used when the polymer material that becomes the dental prosthesis is a heat-polymerizable material. In this case, it is preferable that the heat-resistant temperature of the material of the protrusion 12 is 80 ° C. or higher. This is because many heat-polymerizable materials are usually cured by setting the temperature to 80 ° C. or higher.

  If the protrusion 12 protrudes from the base 11 and enters the recesses of the dental prosthesis technical materials 1 and 2 to hold the dental prosthesis technical materials 1 and 2, the form thereof is particularly limited. It can take any shape. Among these, it is preferable that the protrusion part 12 is columnar as it appears in FIG. Thereby, it becomes easy to carry out elastic deformation and it becomes easy to fit in the recessed part of the technical materials 1 and 2 for dental prosthesis.

  The protrusion 12 preferably has a so-called taper shape that tapers as it extends from the end on the base 11 side to the end on the opposite side. Thereby, it becomes easy to insert the protruding portion 12 into the concave portions of the dental prosthesis technical materials 1 and 2. Moreover, when manufacturing the post | mailbox 10 for a technical material polymerization using a shaping | molding die, this taper acts also as a draft from a type | mold, and can improve the ease of manufacture.

  Concavities and convexities may be provided at the tip of the protrusion 12 (the end opposite to the base 11). According to this, the protrusion 12 becomes more difficult to come out from the recesses of the dental prosthesis technical materials 1 and 2. The shape of the unevenness is not particularly limited, and examples thereof include a textured shape.

  In this embodiment, as can be seen from FIG. 2, the four projecting portions 12 are arranged along the outer peripheral portion of the end surface of the base portion 11. However, the number of the protrusion parts 12 should just be two or more, and the form of the arrangement | sequence is not specifically limited.

For example, in a dental prosthesis technical product for molars, it is preferable that three or more protrusions are arranged along the outer peripheral portion of the base end face from the feature of the form. Therefore, it can be said that the said embodiment is also a shape suitable for the dental prosthesis technical material for molars.
Although the specific dimensions at this time are not limited, the height of the protruding portion (corresponding to the size indicated by IIb in FIG. 2) is considered in consideration of the normal size of the dental prosthesis technical product. Is preferably 5 mm or more. Moreover, 50 mm or less is preferable from a viewpoint installed in a superposition | polymerization device, and 20 mm or less is preferable from a viewpoint of the moldability at the time of manufacturing the post | mailbox 10 for technical material polymerization.
On the other hand, the outer diameter (corresponding to the size indicated by IIa in FIG. 2) is preferably within 10 mm in consideration of the normal size of a dental prosthesis technical product. If it is larger than this, there are many cases where it cannot be properly inserted into the recess of the dental prosthesis technical product. The outer diameter is preferably 3 mm or more. If it is thinner than this, it becomes difficult for a plurality of protrusions to press the wall of the recess in the recess of the dental prosthesis technical product, and the possibility that the holding is weakened increases.

On the other hand, in a dental prosthesis technical product for anterior teeth, two or more protrusions are erected from the base end face, and the protrusions are arranged in a direction along the diametrical direction of the base end face. It is preferable that they are arranged. The arrangement pattern is not limited, and may be arranged in a straight line, for example, or three or more protrusions may be arranged two-dimensionally in a so-called xy direction.
Although the specific dimensions at this time are not limited, the height of the protruding portion (corresponding to the size indicated by IIb in FIG. 2) is considered in consideration of the normal size of the dental prosthesis technical product. Is preferably 5 mm or more and 50 mm or less, and more preferably 20 mm or less for the same reason as above. Moreover, in the cross section orthogonal to the height direction among the protrusions, the size in any direction is preferably within 10 mm. In addition, from the viewpoint of moldability when manufacturing the technical product polymerization post 10, at least the connection portion with the base portion 11 (that is, the root portion of the protruding portion 12) is preferably 1 mm or more.

  Furthermore, since the protruding portion is formed of the soft material as described above, it is preferable that a part of the protruding portion can be excised with scissors, a cutter, or the like, and can be adjusted to a necessary shape.

The technical-material superposition | polymerization holding | maintenance apparatus 100 provided with the above structures, and the dental prosthesis technical materials 1 and 2 are combined as follows, for example. FIG. 3 shows an explanatory diagram. FIG. 3 is a diagram in which these members are combined and shown in FIG.
As can be seen from a comparison between FIG. 1 and FIG. 3, one end of the pin 4 is inserted into the hole 3 b of the technical-material polymerization stand 3, and the pin 4 is erected. The other end of the pin 4 is inserted into a hole provided in an end surface on the side where the protruding portion 12 is not provided in the base portion 11 of the technical product polymerization post 10. As a result, the technical product polymerization post 10 is erected on the technical product polymerization stand 3 via the pins 4.
The erected product polymerization post 10 is arranged such that the protrusion 12 extends upward. Then, the dental prosthesis technical materials 1 and 2 are disposed at the tip thereof. In more detail, the front-end | tip of the some protrusion part 12 is inserted in the recessed part provided in the dental prosthesis technical products 1 and 2. FIG. At this time, it arrange | positions so that the some protrusion 12 may press the inner wall of a recessed part so that it may spread in the said recessed part. Since the dental prosthesis technical materials 1 and 2 are held in this way, more stable holding is possible.

In such a combined state, each of these members is placed in a polymerization vessel, and the polymerization material provided on the outer surfaces of the dental prosthesis technical materials 1 and 2 is cured. If the polymerization material is a photopolymerization type material, it is installed in a photopolymerization device, and if the polymerization material is a heat polymerization type material, it is installed in a heating polymerization device.
In any polymerization vessel, vibration may be large when polymerization is carried out while rotating by a rotary table. However, according to the post 10 for polymerization of a technical product, the technical materials 1 and 2 for dental prosthesis can be stably provided. It is strong against the vibration. Further, the projecting portion 12 of the post for polymerizing the post 10 supports and holds the dental prosthesis technical materials 1 and 2 from the inside of the concave portion, and is thus disposed on the outer surface of the dental prosthesis technical materials 1 and 2. In particular, in the case of photopolymerization, curing is appropriately performed without causing a shadow on the polymerized material.

  In the technical product polymerization post 10 of the above embodiment, an example in which a hole into which the pin 4 can be inserted is provided on one end surface side of the base 11 has been described. According to this, since the conventionally used technical product polymerization stand 3 and pin 4 can be used without change, the versatility is high.

  FIG. 4 is a view for explaining the second embodiment, and is an explanatory view corresponding to a front view of the post 20 for polymerization of a technical product. The technical material polymerization post 20 is different from the technical material polymerization post 10 in that a standing projection 21 is provided on the lower surface side of the base portion 11. Since other parts are common to the above description, the same reference numerals are given and the description is omitted.

  The standing projection 21 is a rod-like member disposed on the side opposite to the protruding portion 12 in the base portion 11 and is inserted into the hole 3b of the above-described technical product polymerization stand 3 to erect the technical product polymerization post 20. It is possible to do. According to this, since the pin 4 is not required separately, the number of members can be reduced. Therefore, if it has such a function, the shape and material will not be specifically limited. However, from the viewpoint of manufacturing, it is preferable that the material is the same as that of the base 11 and is integrally formed with the base 11.

  FIG. 5 is a diagram for explaining the third embodiment, and is an explanatory diagram corresponding to a front view of the post 30 for polymerization of a technical product. The technical product polymerization post 30 is different from the technical product polymerization post 10 in that a pedestal 31 is disposed on the lower surface side of the base 11. Since other parts are common to the above description, the same reference numerals are given and the description is omitted.

The pedestal 31 is a block-like member disposed on the opposite side of the base 11 from the protruding portion 12. The pedestal 31 has a function of maintaining the posture in which the base portion 11 and the projecting portion 12 are erected without using a stand or pin for polymerization of a technical product. Therefore, if it has such a function, the shape and material will not be specifically limited.
According to the technical material polymerization post 30, a dental prosthesis technical material is arranged on the technical material polymerization post 30, and is installed in the polymerization device as it is without using the pins 4 and the technical material polymerization stand 3. Therefore, convenience is further improved.

  FIG. 6 is a perspective view illustrating the fourth embodiment, which is an exploded view of the technical-polymer polymerization holding device 200. The technical product polymerization holding device 200 includes a technical product polymerization stand 203 and a technical product polymerization post 10. Since the post 10 for polymerization of the technical product is the same as that described above, the same reference numeral is attached and the description thereof is omitted.

  The technical product polymerization stand 203 is a member that functions as a pedestal for holding the technical product polymerization post 10 in an upright posture, and includes a cylindrical main body 203a as a whole. The main body 203a is provided with a plurality of holes 203b extending from the upper end surface toward the lower end surface. One end of the base 11 of the technical material polymerization post 10 is inserted into the hole 203b so that the technical material polymerization post 10 can be erected.

  That is, according to the technical-polymer polymerization holding device 200 of this embodiment, the technical-polymer polymerization post 10 can be erected by directly inserting the base 11 of the technical-polymer polymerization post 10 into the hole 203b without the pin 4 being interposed. Can do. Therefore, the pin 4 is not required.

  Here, the technical product polymerization stands 3 and 203 of each of the above-described embodiments are not particularly limited as long as the technical product polymerization post 10 can be erected in accordance with the respective purposes. For example, the main bodies 3a and 203a do not necessarily have a columnar shape, and may have a polygonal column shape. Also, the holes 3b and 203b are not limited to being through holes or holes that do not pass through. Further, the cross-sectional shape perpendicular to the longitudinal direction of the holes 3b and 203b is not particularly limited, and a shape as required can be applied, such as a circle, a polygon, and a slit.
