Description

  The present invention relates to a denture that is used as a part of a so-called deadly garment that is mounted in the body's mouth.

  The last figure of the deceased wishes to keep the face of the bereaved family as it was. The face of the white front teeth is just a little peeking through the slightly open mouth, and even if the mouth is loose, it becomes a smiling face, and the bereaved family is also pleased.

  Currently, it is said that about 1 in 5 people use dentures (generally called “dentures”), and as the aging society progresses, the population of denture users will expand further. It is expected to go. Many of the deceased were dentist users in their lifetime, and these dentures consisted of artificial teeth made of ceramics and the like, and denture bases made of chemical synthetic plastics such as acrylic resin that supports the artificial teeth or metal. However, when trying to incinerate this denture, the metal is non-flammable, and the chemically synthesized plastic not only generates high heat and damages the incinerator, but also generates harmful gases. For this reason, it is said that it is not preferable to cremation a body that had been fitted with dentures as it is, and it was necessary to remove the dentures by the time of extraction at the latest. However, by removing the dentures, the cheeks became dull and the human phase became poor, and when criminalizing this dead, the bereaved family had to look at the deceased with a different face from before life, amplifying sadness There was a problem.

  From these various circumstances, it has been performed that the denture as a part of the so-called death is attached to the body to prevent the cheek from becoming deflated, and the denture is removed from the body before cremation, In recent years, there has been proposed a denture made of wax that does not leave a residue even if all of the artificial teeth and denture base are burned easily and burned (Patent Document 1). According to this denture, the work which removes a denture from a dead body in the case of cremation becomes unnecessary.

  FIG. 7 is a front view showing a state in which a portion of the artificial tooth 3c and a part of the labial floor 5 forming the gum portion are cut out from the denture 1. FIG. An example of the work performed at this time is as follows with reference to FIGS. First, the tooth cut groove 62 is cut from the lower end 62a toward the upper end 62b to the connecting portion 50b with the tooth bottom cut groove 50, and then the tooth cut groove 64 is moved from the lower end 64a toward the upper end 64b. 50 to the connecting portion 50d. Next, the tooth width cut inner groove 82 is cut from the upper end 82b toward the lower end 82a to the connecting portion 70b with the gingival bottom cut groove 70, and then the tooth width cut inner groove 84 is cut from the upper end 84b toward the lower end 84a. Cut to the connecting portion 70d with the bottom cut groove 70. At this stage, the artificial tooth 3c and a part of the labial floor 5 constituting the gum portion are formed between the bottom and bottom of both the bottom cut groove 50 and the bottom cut groove 70. It will be in the state connected with the denture base 2 only through the range of the connection part 50b-50d (range of the connection part 70b-70d). Finally, by cutting the thin molded portion 7 within this range, the artificial tooth 3b and a part of the labial floor 5 forming the gum are collectively separated from the denture base 2.

  By comprising in this way, when mounting the denture 1 in the oral cavity of the corpse, it can be easily processed and mounted regardless of the presence or absence of residual teeth, and the bereaved family can obtain a sense of comfort at a low cost. . Further, the tooth width cut outer grooves 41 to 45 and the tooth width cut inner grooves 81 to 85 are provided at positions facing the inner and outer surfaces of the labial floor 5, and the tooth bottom cut groove 50 and the gingival bottom cut groove 70 are provided. Is provided at a position where the inner and outer surfaces of the palate side floor 4 are opposed to each other, so that the thin molded portion between the opposed groove bottoms can be markedly and easily cut out with a cutter knife or scissors. At the same time, it is possible to cut off with the power of a finger, so that workability is extremely excellent. In addition, as shown in the configuration in which the connecting portions 4a and 4b are provided on both sides of the bottom cut groove 50 and the connecting portions 4c and 4d are provided on both sides of the gingival cut groove 70, the cut portions 41 to 45, 50, 61 to 65, 70 and 81 to 83 are not configured to reach the outer edge of the denture base 2. As a result, it is possible to prevent a situation in which the denture base 2 is cut off by force majeure and partly dissipated during a cutting operation or during normal handling. Furthermore, since the denture 1 is made of silicone rubber, elastomer, or urethane resin having excellent flexibility, it can absorb the difference in the shape of the individual alveolar ridge, so that the denture 1 is individually manufactured according to the shape of the individual alveolar ridge. There is no need, and it is possible to mass-produce small varieties of only a predetermined shape.

  It is preferable that the artificial tooth 3 is colored white and the denture base 2 is colored reddish according to the actual color tone, but the tip of the artificial tooth 3 is visible from the slightly open mouth of the body. If it is about 3 mm, you may color the whole including not only the artificial tooth 3 but the denture base 2 to the color approximated to the natural tooth. In this case, the manufacturing process can be simplified and the manufacturing cost can be reduced.

  As shown in FIG. 8, the denture according to the present invention is intended to form a tight mouth by inflating a lip that has been deflated when worn in the mouth of a corpse. As a result, the face of the corpse can be kept in its original state of life, and the bereaved family can be pleased.
