Description

  The present invention relates to an intraoral insert that is inserted into the oral cavity, and more particularly to an intraoral insert that adjusts the appearance of a corpse face.

  Conventionally, there is a denture as one of artificial parts made to supplement a part of the body like a prosthetic hand or a prosthetic leg. The denture is made of, for example, an artificial tooth made of earthenware and a denture base made of a chemically synthetic plastic such as MMA (methyl methacrylate) that supports the artificial tooth. Moreover, in the partial denture used in the state in which some teeth remain, the metal spring (clasp) for hooking a denture base on a tooth is used.

  By the way, when such a denture is cremated together with the body, the dentures made of chemically synthesized plastic melt, and seizure and damage to the bone and cremation furnace occur, toxic gases such as dioxins are generated, Problems such as incomplete combustion due to lack of oxygen may occur. Also, if the partial denture is cremated with the body, the clasp may remain burnt. On the other hand, if the dentures mentioned above are not applied to the body, the mouth falls and the cheeks are stuffy, and as a result, the crawler may show a different facial expression than before, and the sense of closeness may fade. is there.

  There is also the problem of postmortem rigidity. Postmortem stiffness begins around the jaw about 1 to 3 hours after death, and the whole body stiffens after about 48 hours after death. Therefore, in the past, because of these various circumstances, the denture was applied to the body immediately after death to prevent the cheeks from becoming danky, and the denture was removed before the cremation was performed. It was common to prevent seizure to the furnace.

  In recent years, dentures that do not require such complicated work have appeared. For example, there is a denture (Patent Document 1) made of wax that is easily burned so that no residue remains even after incineration. In addition, a facial correction tool that maintains the appearance of the face before birth (Patent Document 2) and an intraoral insertion tool for adjustment that adjusts the face part of the body while eliminating the need to remove it from the mouth of the body during cremation (Patent Document 3) There is.

  However, the inventions described in Patent Documents 1 to 3 described above have the following problems.

  That is, the invention described in Patent Document 1 requires a model / apparatus such as an edentulous jaw model or a metal split-type metal frame so that the quality on appearance does not change from a conventional denture. Therefore, there is a problem that it is suitable for mass production of the same product, but is not suitable for small-lot production of various kinds such as custom-made (paragraph numbers [0001], [0006], [0007] of Patent Document 1). ).

  The invention described in Patent Document 2 is a facial correction tool that focuses on maintaining the appearance of the face as it is, and plays a role as a stuffing. In order to prevent the human phase from becoming a poor phase by stretching the meat, attention is focused only on the “shape” (paragraph number [0031] of Patent Document 2). Therefore, for example, when the body is left lying on its back and the mouth is opened due to the weight of the body, an inhuman face correction tool (see FIG. 1 of Patent Document 2) is opened from the mouth. There is a problem of seeing and aggravating sadness to the bereaved family.

  Furthermore, since the invention described in Patent Document 3 is a denture-shaped intraoral insertion tool made in advance, there is no problem that an inhuman instrument can be seen from the open mouth as described above. However, in the invention described in Patent Document 3, when the intraoral insertion tool is formed in a size and shape corresponding to “all” of the dentition, similar to the invention described in Patent Document 1, it is suitable for small-lot production of various varieties. It will encompass the problem of not. In this regard, it is also conceivable that unnecessary dentitions are removed from all dentitions, and the intraoral insertion tool is formed in a size and shape corresponding to “part of the dentition” (paragraph number [0008] ]). However, in such a case, the strength of stretching the cheek meat that is to be relaxed and shrunk is reduced, and there is a possibility that the face becomes a senile face with many wrinkles and the human phase becomes poor.

  As described above, the inventions described in Patent Documents 1 to 3 described above are suitable for low-volume production of various varieties, show natural teeth and gums to the bereaved family even when the mouth is open, and stretch the cheek meat. It was not possible to simultaneously solve the three problems of not reducing the strength to be reduced.

  The present invention has been made in view of these points, and the purpose of the present invention is to show the natural teeth and gums to the bereaved family even when the mouth is open, and to increase the strength of extending the cheek meat. Another object of the present invention is to provide an intraoral insert that can be secured sufficiently and is suitable for small-lot production of various products such as custom-made products.

  In order to solve the problems as described above, the present invention consists of a natural tooth and gum form for the part that can be visually recognized from the appearance when the mouth is opened. The pseudo tooth part is provided by the cheek extension part as a stuffing for extending the cheek meat for the other parts, and at least one of the pseudo tooth part and the cheek extension part is deformed by heat input. It is characterized by being formed of a plastic material that can be used.

  More specifically, the present invention provides the following.

  (1) An intraoral insertion tool configured to include a pseudo tooth portion that can be visually recognized as a form of teeth or gums, and a cheek extension portion that extends relaxed cheek meat, and is inserted into the mouth of a corpse, At least one of the pseudo tooth portion and the cheek extension portion is formed of a plastic material that can be deformed by heat input.

  According to the present invention, since the intraoral insertion tool to be inserted into the corpse of the corpse, the portion visible from the outside of the oral cavity is a pseudo tooth portion formed in the form of a tooth or gum, Even if is open, it can be shown to the bereaved family as teeth and gums.

  Therefore, for example, if the body is left lying on its back and the mouth is opened due to the weight of the body, non-human absorbent cotton and facial correction tools can be seen from the mouth, which is sad to the bereaved family. It is possible to prevent amplification of thoughts.

  In addition, the present invention is an intraoral insertion tool that is inserted into the corpse of the corpse, and the portion that cannot be visually recognized only after the mouth of the corpse is slightly opened stretches the cheek meat that is about to relax and contract by rigor after death. Since it is the cheek meat extension part to be made, the intensity | strength which expands cheek meat can be maintained.

  Therefore, for example, it can be prevented that the remains of the body are cheeks, and the face of a senile with a lot of wrinkles, and the human phase becomes poor, and the facial expression different from his life is shown to the bereaved family.

  Furthermore, according to the present invention, since at least one of the above-described pseudo tooth portion and the above-described cheek extension portion is formed of a plastic material that can be deformed by heat input, it is inserted into the oral cavity of the corpse. When inserting a tool, it can be thermally deformed to match the body.

  That is, generally, the form of the oral cavity of the corpse is often different from the form of the oral cavity of the dead body due to contraction of the cheek meat, etc. When the internal insertion tool is manufactured, it may not be successfully inserted into the oral cavity. However, according to the present invention, the intraoral insertion tool may be cut or scraped according to the shape of the body of the oral cavity. As a result, the intraoral insertion tool can be inserted well, and as a result, the appearance when inserted can be as close as possible to the appearance before life.

  Here, in the present invention, it is sufficient that only the form of the pseudo tooth portion, not the entire part of the intraoral insertion tool, can be recognized as the form of teeth and gums from the outside of the mouth. Therefore, for example, it is sufficient that only the pseudo tooth portion is in the form of the central incisor, lateral incisor, canine and first premolars of the upper and lower jaws, and a wide variety of oral cavity can be produced at a lower budget than conventional intraoral insertion tools. An internal insert can be manufactured.

  (2) The intraoral insert according to (1), wherein the plastic material includes paraffin wax.

  According to the present invention, since the plastic material described above includes paraffin wax, the plasticity of the intraoral insert is realized, so when providing the intraoral insert, cutting or dividing, It can be softened or melted.

  Therefore, when the intraoral insertion tool is inserted into the corpse of the corpse, it can be deformed in accordance with the form of the corpse in the oral cavity and the appearance before life.

  (3) The intraoral insertion tool according to (1) or (2), wherein white and red pigments are mixed in the pseudo tooth portion.

  According to the present invention, since the pseudo tooth portion is mixed with white and red pigments, the pseudo tooth portion includes a portion exhibiting a tooth color (white) and a portion exhibiting a gum color (red). The intraoral insertion tool provided with the pseudo tooth portion can be manufactured.

  Therefore, for example, even if the body is left lying on its back and the mouth is opened by the weight of the body, natural teeth and gums can be shown to the bereaved family.

  (4) The intraoral insertion device according to any one of (1) to (3), wherein a seal that can be visually recognized as a form of a tooth or a gum is attached to the pseudo tooth portion.

  According to the present invention, since the pseudo tooth portion is affixed with a seal that can be visually recognized as the shape of a tooth or gum, the pseudo tooth portion is different in size, color, and shape from a simpler and lower budget than the conventional one. An intraoral insertion tool having a tooth portion can be manufactured.

  The “seal” here can be selected in accordance with desired conditions such as size, color, shape, angle, etc., with reference to, for example, a pre-life photograph of the body.

  As described above, according to the present invention, the intraoral insertion tool is composed of a pseudo tooth part that can be visually recognized as a tooth or gum form, and a cheek extension part that stretches relaxed cheek meat, and these Since at least one of them is formed of a plastic material that can be deformed by heat input, the appearance of the oral cavity of the body is brought close to the state of life and natural teeth even when the mouth is opened. You can show the gums to the bereaved family. In addition, sufficient strength for stretching the cheek meat can be secured, and in addition, an intraoral insert suitable for high-mix low-volume production such as custom-made can be provided.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

[Intraoral insert according to the first embodiment of the present invention]
FIG. 1 is an explanatory diagram for explaining an intraoral insert 1 according to a first embodiment of the present invention.

  In FIG. 1, an intraoral insert 1 according to the first embodiment of the present invention includes a pseudo tooth 2 that can be visually recognized as a tooth or gum form, and a cheek extension 3 that extends relaxed cheek. , Is composed of.

  The pseudo tooth portion 2 has a horseshoe shape, and is manufactured using, for example, paraffin wax. The melting point of paraffin wax is about 40 to 70 ° C. By using paraffin wax as a raw material, the intraoral insert 1 having a combustion temperature lower than that of the corpse can be provided.

  Moreover, the pseudo tooth part 2 is colored by mixing a pigment into the melted paraffin wax. For example, an edible pigment is used as the pigment, and the gum portion is colored with edible red No. 104 in the color of the gum. Since the solidified paraffin wax is white if it is not colored, the tooth portion may not be colored. Since the texture when the paraffin wax is solidified is a texture that does not feel uncomfortable even if it is inserted into the corpse, the intraoral insertion tool 1 that is less discomfort in appearance can be produced by coloring the paraffin wax. In addition, by coloring with reference to a photograph before life, it is possible to make the color suitable for the person who became the body.

  The pseudo-tooth portion 2 represents a portion that can be visually recognized from the appearance when inserted, for example, the central incisor, the side incisor, the canine and the first premolar, and the gums of the upper and lower jaws. It is not necessary to reproduce the shape of the back side of the tooth because it may be a shape that can be seen. Further, it is not necessary to separate the upper jaw portion and the lower jaw portion, and they may be integrated.

  Next, the cheek meat extension part 3 has a pair of elongated shapes, and is manufactured using, for example, paraffin wax. The cheek meat extension portion 3 is bonded to the pseudo tooth portion 2 with an adhesive or the like, and has a function of extending the cheek meat.

At this time, the cheek extension 3 is shaved in accordance with the body, softened with a hot water bath, the surface is beaten and melted, and applied to the oral cavity in the form of being in close contact with the chin of the body. The stretched state of the cheeks is matched to the expression of the past with the size of the cheek stretched part 3 while referring to the photographs before the birth. Moreover, the pseudo-tooth part 2 can choose the thing close | similar to the appearance of the dead body from the inside by preparing multiple types from which the shape and size of a tooth differ.

  In addition, since postmortem stiffness starts from around the jaw in about 1 to 3 hours after death, it is desirable to insert the dead body quickly after death. Moreover, you may cut | disconnect and insert in the dead body whose mouth is not opened by rigidity after death. If the cut surface is rolled and inserted, it can be joined again.

  In this way, by filling the buccal meat extending portion 3 of the intraoral insertion tool 1 according to the first embodiment of the present invention in the oral cavity, it is possible to prevent the cheek from becoming a stuffy state, and The pseudo tooth portion 2 can show the shapes of the central incisor, the side incisor, the canine, and the like that can be seen from the appearance. Moreover, since the pseudo-tooth part 2 can provide a plurality of forms with a low budget as compared with a conventional complete denture-shaped intraoral insertion tool, a plurality of pseudo-tooth parts 2 can be naturally produced from the body. Can be selected. And the appearance of the face of a corpse can be brought close to the state before life, and the corpse with a little discomfort close to life can be shown to the bereaved family. Furthermore, since the intraoral insertion tool 1 made of paraffin wax burns at a lower temperature than the corpse even if cremation is performed in the cremation furnace together with the corpse, seizure, damage to the bone and the cremation furnace, generation of dioxins, etc. Can be suppressed.
