Description

  The present invention relates to an entirely new denture which is made difficult to be detached by the special structure of the surface in contact with the lip of the back of the lip.

  Dentures In particular, what is important for making a complete denture is the impression that it was molded using a personal tray. A base plate is made from this impression, wax is put on this, and an occlusal floor is made. An artificial tooth array is formed in the wax part of the occlusal floor using an articulator to obtain a denture. After this, the base plate is re-waxed, and after denture placement and meat formation, the denture is embedded in plaster in a flask, and the wax is dissolved by heating and the base plate is removed to form a mold. Subsequently, a gum-colored pink resin is poured into a space formed by taking out the wax and the base plate and pressed, and the flask is heated to solidify the resin. When the polymerization is over, remove it from the flask, destroy the plaster and dig out the denture. The denture thus obtained is set in the articulator and the meshing adjustment is repeated, and deburring and grinding are performed to complete the entire denture. The above is an example of a dental technician who makes full dentures.

  The above-mentioned all-in-the-floor dentures fit well when they are just made, but they do not fit well in use. It is because even if it bites a thing, the gum of a living body and sometimes the bone of the jaw will also be deformed by the force. The trouble of saying that dentures do not fit by this directly arises. That is, it is not easy to solve the problem that dentures do not fit.

  However, I just can not say that. There are many patients who are worried that their dentures do not fit in reality. Therefore, it is an object of the present invention to solve such a problem and to make it possible for a well-made denture to fit the patient for as long as possible.

  Prior to the solution of the above-mentioned problems, the present inventor has come to question whether it is necessary in the first place to make it perfectly fit to the upper jaw by making full use of the above-mentioned technique, particularly regarding the complete denture for upper jaw. The If raw gums and bones are deformed by the force of biting things, it will be necessary to make retouching immediately if you make all the dentures very carefully, and you have to do it over and over again It is gone. Therefore, the present inventor has found that it is better to make the upper jaw loose but hard to come off. Although the following description is directed to a full denture for upper jaw, the present invention is also applicable to a denture for lower jaw.

  That is, the above-mentioned subject can be achieved by providing a denture characterized in that it has a groove in the lip front of the upper lip white lip in the denture base front surface (the surface touching the upper lip white lip back). If it is desired that the denture base front part be well attached to the upper lip white lip, for example, it is conceivable to attach a suction cup later, but realistically, such allowances are upper lip white lip and denture base front It is not between the department. Therefore, we made a groove in the denture base front part, and it was made difficult to come off even if the lip of the upper lip white lip part enters this groove. Lips come into this groove naturally and appear to hold the denture. The groove is formed by cutting or cutting with a cutting tool such as an electric reamer. The shape of the groove is arbitrary. Therefore, for example, lateral grooves can be provided on the back side of the central groove, divided into the right side and the left side, or the lateral grooves on the right side and the lateral grooves on the left side can be provided integrally.

  In order to form a groove by the above-mentioned molding, a step of engraving a groove into which lip of lip of the upper lip is put in an impression taken from a patient, and a groove is copied from this impression to make a model with a projecting part as a mold; A process of making a base plate from a model, a process of making wax with wax on this base plate and eluting wax from an occlusal floor where artificial teeth were placed, removing a base plate, and injecting resin into the space from which wax and base plate were removed. And a step of copying a groove from the projecting portion of the model to the resin side. That is, the groove is copied to the resin from the model at the time of artificial dentition.

  In order to form a groove by cutting with a cutting tool such as the electric reamer, a process of making a model from an impression taken from a patient, a process of making a base plate from the model, and wax on the base plate to make artificial teeth arrangement The process of eluting the wax from the occlusal floor and removing the base plate, injecting the resin into the space from which the wax and the base plate were removed, and making a denture, and the lip of the upper lip white lip back of this denture contacts And D. Engraving a groove into which the lip enters the region. This is a method in which a cutting tool is used to form a groove directly on the area where the lip of the upper lip, white lip and the back of the denture is in contact.

  By the way, the groove may be a dimple in accordance with the shape of the groove. In the case of the above-mentioned lateral grooves, several dimples as grooves are disposed around the lateral groove. The number of dimples may be odd or even. Also, it may be provided to avoid the area of the upper lip zonules or not. The dimples may be provided by molding as described above or cutting.

  Next, a denture having adsorption dimples adsorbed on the jaws can be provided on the mucous membrane surface. When the entire denture is mounted on the upper jaw, the meat on the surface of the upper jaw wet with saliva adheres to the dimple surface, but since the dimples are concave portions, negative pressure is generated in the dimple when the meat is separated. Is less likely to leave. That is, the dimples act like a sucker. This helps the denture try to stay by the groove. The adsorption dimples are formed by molding or scraping with a cutting tool such as an electric reamer.

  In the case of providing the adsorption dimples by the above molding, the process of engraving the adsorption dimples for adsorbing the jaws to the impression and copying the adsorption dimples from the impression to form a model having projections as a mold is included. You should do it. In addition, when providing the adsorption dimples by cutting, a step of digging the adsorption dimples to be adsorbed onto the jaws using a motorized cutting tool such as an electric reamer on the mucous surface of the hardened resin as an example. Should be included.

  In addition to the adsorption dimples, it is possible to attach a large number of fine depressions that adsorb to the jaws to the mucous membrane surface. It is made to have many fine dents in the side which touches the upper jaw of the dentition, ie, the adhesive surface, of the upper jaw part of the denture. When the entire denture is mounted on the upper jaw, the flesh of the upper surface wetted with saliva adheres to the surface having the fine dents. Then, the adhesion to the surface of the upper jaw is generated by the large number of fine dents. This helps the denture try to stay by the groove. The size of the fine dent is the size of various abrasives such as sand. Microscopically, such fine dents can also be considered as a kind of adsorption dimples.

  Such fine dents may be provided with a dent in the impression as described above, and may be attached by molding such as passing through a process of copying it to a model as a mold of many fine projections, or using alumina sand, for example, using a sandblasting gun. Or the like by spraying on the adhesive surface.

  According to this invention, the denture base front portion is provided with a groove into which the lip of the upper lip and the back of the upper lip enters. When wearing a denture, the lip naturally enters the groove and makes this part hold the denture. It produces an action that makes it difficult for the denture to come off. This will reduce concerns even if the dentures made together do not fit. Alternatively, it is possible to make the dentures relatively loose without making them fit on the upper jaw.

  FIG. 5 is an explanatory view of the first embodiment in a perspective view.   It is explanatory drawing of the manufacturing method of the complete denture 1 for upper jaws.   FIG. 7 is an explanatory view of the second embodiment in a perspective view.   It is explanatory drawing of the manufacturing method of all dentures 2 for upper jaws.

  The full denture 1 for the upper jaw will be described with reference to FIGS. 1 and 2. The whole floor denture 1 has a lateral groove 13 in which the lip of the upper lip white lip area is inserted in the area in contact with the upper lip white lip area of the front of the denture base 10 on which the artificial tooth arrangement 11 is formed. In this embodiment, the lateral groove 13 is provided as a groove extending laterally from end to end of the denture base 10, and is copied to the resin by molding. In addition, the code | symbol 12 is an adhesive surface which touches a jaw.

  At the part of the patient's impression molded using the personal tray, on the side that touches the lip of the upper lip white lip, the side groove is carved from the right end to the left end using a reamer, and from this impression the lateral groove A model having protrusions as a mold is made (step S1), a base plate is made from this model, and a lateral groove is copied from the protrusions on the base plate (step S2). (However, copying of the lateral groove to the base plate side at this time is merely a copy, and it does not mean that it will happen.) Then, a wax wax is made on the base plate, and artificial dentition is performed here to make a denture (Step S3). Furthermore, the occlusal floor after artificial tooth placement is embedded in plaster in plaster and heated to perform wax wax work and remove the base plate (step S4), and inject resin into the space from which the wax and base plate are removed. Then, pressure is applied to copy the lateral groove 13 from the protrusion to the resin (step S5). (In this state, it is important that the lateral groove 13 which is a recess continuously connected to the resin side from the model is shown.)

  After this, the resin is irradiated with microwaves and heated in a microwave oven to cure the resin, thereby completing the polymerization work, removing the plaster at the time of embedding, and removing it from the model to obtain a complete denture.

  When the complete denture 1 thus obtained is mounted in the mouth, the lateral groove 13 where the lip meat of the upper lip white lip area is in contact with the upper lip white lip area of the anterior portion of the denture base 10 Since it is provided, the denture is held by the lip that has entered here, causing an effect of making it difficult to remove the denture.

  The above-mentioned configuration can be applied to a complete denture for mandible. In this case, due to wearing in the mouth, the lip of the lower lip near the back of the lower lip naturally enters the lateral groove in the front of the denture base of the lower denture not shown. And the denture is held by the lip flesh which has entered here, and the denture tends to be hard to lift.

  The full denture 2 for the upper jaw will be described with reference to FIGS. 3 and 4. The whole floor denture 2 has dimples 23 in a lateral row in which the lip of the upper lip white lip area enters in the front part of the denture base 20 on which the artificial tooth array 21 is formed and the area close to the upper lip white lip area. It is a thing. In place of the lateral groove 13 of the first embodiment described above, five dimples 23 are disposed at the position of the lateral groove 13, and each dimple 23 is cut by a reamer which is an electric cutting tool. .

  That is, after making a model from an impression taken from a patient and making a base plate from this model, a wax wax is made on the base plate and artificial teeth are placed there to make a denture (step S17). Embed in plaster, heat, perform wax wax work, remove the base plate, inject resin to this mark, cure and polymerize (step S18), take out from the flask, destroy plaster and dig out denture, denture base 20 The five dimples 23 containing the lip meat are incised in a horizontal row using a motorized reamer at a portion where the lip meat around the upper lip white lip of the front part is in contact (step S19).

  When the complete denture 2 thus obtained is worn in the mouth, a part of the lip meat in the back of the upper lip white lip is in contact with the portion of the upper lip back of the anterior portion of the denture base 20 of the full dent 2 Since the dimples 23 in which one row of five places is provided are provided, the dentures are held by the lip flesh that has entered the dents 23, and the dentures are less likely to come off.

  The dimples 23 may be provided so as to avoid the upper lip zonules (for example, the central dimples at five locations may be eliminated). The size, shape and number of dimples are optional design matters. Moreover, it does not need to be in the said horizontal single row.

  Reference numeral 22 denotes an adhesive surface which touches the upper jaw of a living body, but it is also possible to provide many suction dimples 24 for adsorbing to the jaw. Since the denture 2 is entirely adsorbed to the upper jaw by the adsorption action generated by the adsorption dimples 24, the effect of the dimple 23 (or the lateral groove 13 in Example 1) can be further enhanced.

  With regard to this configuration, reference will be made to the "denture to be adsorbed to the jaw" of Japanese Patent Application No. 2016-076151 filed by the present applicant.

  The present invention greatly contributes to the development of dental care. The present invention can be sufficiently applied to a denture as a joke product for party goods.
