Description

  The present invention relates to an improvement of a maxillary denture to be attached to a maxilla in a human oral cavity.

  If all of the natural teeth that have grown on the upper jaw in the oral cavity, or if most of them have left one or two of them, the total dentures or remaining teeth with artificial teeth arranged side by side in a horseshoe shape A denture similar to a full denture with an open fitting hole is used by joining and holding the upper jaw.

  A typical example is shown in FIG. The maxillary denture 1 includes an artificial tooth 2 arranged side by side in a horseshoe shape, a gum fitting part 3 having a recess fitted into a gum (not shown) of the upper jaw part, and a palate (oral cavity) of the upper jaw part. A palate joint portion 4 that is surface-joined to an inner arch-shaped upper wall) is integrally formed. In addition, when a remaining tooth exists in the upper jaw part, the fitting hole 5 which makes use of this in the part corresponding to the remaining tooth of the gum fitting part 3 may be formed.

  By the way, the palate in the oral cavity, where natural teeth are sufficiently grown on the upper jaw and do not require dentures, is something like a wrinkle that swells diagonally from the center of the upper jaw ( In the daily life of a person, the surface of the tongue body (especially the tip of the tongue) in the oral cavity always touches this “palatoma” unconsciously without any sense of incongruity.

  However, as shown in FIG. 6, when there is no natural tooth in the upper jaw portion and the denture 1 for the upper jaw is forced to fit, the “palatoma” that the tongue tip should contact is completely hidden by the palatal joint 4. End up. The contact surface 6 with the tongue body in the palate joint 4 has not been given any consideration so far, and the entire surface remains a mirror surface. Therefore, the tongue surface always has a smooth contact surface 6. Will touch. As a result, the surface of the tongue and the tip of the tongue have a sense of incongruity that is far from the unintentional contact feeling remembered in the above-mentioned palatal fistula. It has become. For this reason, the current situation is that foods do not pass through the throat, and chewing cannot be maintained, so that the foods that are supposed to be fun can be hindered.

  Therefore, in order to reduce the unpleasant sensation of the tongue as much as possible, a technique is realized in which a floor hole 7 is formed in the middle of the palate joint 4 and a part of the tongue is directly in contact with the palate through the floor hole 7. This is proposed as Kaihei 5-70518 (Patent Document 1).

Utility Kaihei 5-70518

  However, the foreign body and the sense of discomfort that the tongue senses are mostly concentrated on the tip of the tongue, but the technique of Patent Document 1 has the floor hole 7 in the middle of the palatal joint 4, so the tongue The surface directly touches only around the central upper wall of the palate, and the “palatal fold” that the tip of the tongue is supposed to touch is hidden by the palate joint 4. For this reason, the tongue tip cannot avoid contact with the contact surface 5 that is still in a mirror state, and the mirror contact may cause a foreign object feeling or a sense of discomfort to the tongue tip. I can't.

  It is an object of the present invention to eliminate foreign body sensation and discomfort caused by contact of the tongue surface and the tip of the tongue when a maxillary denture is mounted, and to suppress foreign body rejection.

In order to achieve the above object, the present invention has the following features. In other words, the artificial teeth are arranged side by side in a horseshoe shape, and they are interviewed by a gum fitting part having a recess to be fitted in the gum of the maxilla in the oral cavity and the palate of the maxilla (an arch-shaped upper wall in the oral cavity). In the maxillary denture formed integrally with the palatal joint to be joined, the contact surface with the tongue in the palatal joint is composed of a tongue-sensitive surface that has been processed to give a normal feeling to the tongue It is characterized by having.

  By making the contact surface of the palatal joint part of the maxillary maxillary denture with the tongue body as described above, contact with the tongue surface of the tongue body becomes normal at the time of wearing, and the surface of the tongue body and The tip of the tongue does not feel a foreign body feeling or a sense of incongruity and can suppress foreign body rejection.

  As the tongue-sensitive surface, a particle embossing surface obtained by embossing particles (Claim 2), a corrugated embossing surface obtained by embossing a ridge (Claim 3), a corrugated surface processed by corrugation (Claim 4), and A lattice or mesh raised surface obtained by embossing a lattice pattern or a mesh pattern is preferable. By setting it as such a processed surface, the surface becomes familiar with the tongue body surface and the tip of the tongue, and the tongue body itself can even feel a normal feeling of contact and can wipe off a foreign object feeling and a sense of incongruity. Each tongue-sensitive surface is preferably applied to the central area of the palatal joint portion in close proximity to or in contact with the dentition along the dentition of the artificial tooth.

  It is a bottom view which shows the 1st Example of the maxillary denture by this invention.   It is a bottom view of the center area processing part by 2nd Example of this invention.   It is a bottom view of the center area processing part by the 3rd example of the present invention.   It is a bottom view of the center area processing part by the 4th example of the present invention.   It is a bottom view of the center area processing part by 5th Example of this invention.   It is a bottom view of the conventional maxillary denture.

  Embodiments of the present invention will be described below with reference to the drawings. A maxillary denture 10 according to the present invention, as shown in FIG. 1, has a recess to be fitted to the gum of the maxillary part in the oral cavity, and the artificial tooth 2 facing downward is arranged side by side in a horseshoe shape. 3 and a palatal joint 4 that is surface-bonded to the palate of the upper jaw are integrally coupled. In the case where there are remaining teeth in the upper jaw, fitting holes 5 that make use of this may be formed in the remaining tooth corresponding portions of the gum fitting portion 3. The configuration so far is not different from the prior art.

  In the present invention, the entire surface or almost the entire contact surface 6 of the palatal joint 4 with the tongue body is configured as the tongue-sensitive surface 11. This tongue-sensitive surface 11 has been processed so as to make the tongue feel a normal state. In this embodiment, the particle raised surface 11a obtained by raising the particles is selected. As a processing method, it is generally performed by a conventional method such as die-cutting, but surface formation by other methods such as cutting is also possible.

  According to the maxillary denture 10 according to the above embodiment, the surface of the tongue body and the tip of the tongue always come into contact with the particle protruding surface 11a at the time of wearing, but the fine and rough feeling of the particle protruding surface 11a is transmitted to the tongue body. As a result, this contact becomes a normal state, and a foreign object feeling and a sense of incongruity are wiped away, and a long-time wearing is possible.

  FIG. 2 shows a second embodiment of the present invention. In this embodiment, the particle raised surface 11 a according to the first embodiment is applied to the central area CA of the palate joint 4 while being close to or in contact with the tooth row along the tooth row of the artificial tooth 2. FIG. 2 is a proximity example. This central area CA is mainly in contact with the tongue tip of the tongue body, and is approximately coincident with the presence area of the “palatoma” on the inner palate wall in the oral cavity. Therefore, the tongue tip is always in contact with the particle raised surface 11a applied to the central area CA corresponding to the position corresponding to the “palatoma”. The effect and surface processing method according to this are in accordance with the first embodiment.

  FIG. 3 shows a third embodiment of the present invention. In this embodiment, a wrinkle embossing surface 11b obtained by embossing a wrinkle is provided in the central area CA of the palate joint 4. Since the heel-protruding surface 11b imitates the “palate fold”, a feeling peculiar to the “palate fold” can be obtained. Therefore, when worn, there is no foreign object feeling or discomfort on the tongue, but rather a normal feeling can be obtained unconsciously. Other configurations and surface processing methods are the same as in the second embodiment.

  FIG. 4 shows a fourth embodiment of the present invention. In this embodiment, a corrugated surface 11 c having a corrugated surface is applied to the central area CA of the palate joint 4. Therefore, when the tip of the tongue comes into contact with the corrugated surface 11c, a pleasant and bumpy feeling is obtained, and the feeling of relics and discomfort is eliminated. Other configurations and surface processing methods are the same as in the second embodiment.

  FIG. 5 shows a fifth embodiment of the present invention. In this embodiment, the central area CA of the palate joint 4 is provided with a lattice or mesh pattern surface 11d obtained by embossing a lattice pattern or a mesh pattern. Therefore, when the tongue is in contact with the lattice or mesh pattern surface 11d at the time of wearing, a moderate feeling can be obtained. Effects, other configurations, and surface processing methods are the same as in the second embodiment.

  FIG. 1 shows an embodiment in which the entire surface or almost the entire surface of the contact surface 6 is a particle raised surface 11a. In addition to this embodiment, although the illustration of the overall shape is omitted, the contact surface 6 It is also included in the scope of the present invention that the entire surface or almost the entire surface is the ridge raised surface 11b, the corrugated surface 11c, or the lattice (mesh) raised surface 11d.

  The maxillary denture 10 is normally detachable, but can also be applied to a fixed type using an implant.
