Description

  The present invention relates to a denture that can be attracted to a jaw by a special structure of a surface that touches the jaw.

  An important part of making a complete denture, especially a complete denture, is the impression of molding using a personal tray. A base plate is made from this impression, and wax is put on this to make an occlusal floor. An artificial tooth arrangement is formed in the wax portion of the occlusal bed using an articulator to obtain a denture. Thereafter, the wax is re-applied to the base plate, and after the denture arrangement and meat formation are completed, the denture is buried in gypsum in the flask, the wax is melted by heating, and the base plate is removed to form a mold. Next, the wax and the base plate are taken out, a gum-colored pink resin is injected into the space formed, and pressed, and the flask is heated to solidify the resin. When the polymerization is over, remove it from the flask and break the gypsum to dig out the denture. The denture obtained in this manner is set in an articulator and the adjustment of the meshing is repeated, and deburring and polishing are performed to complete the complete denture. The above is an example of a dental technician making full dentures.

  The above-mentioned complete dentures fit well when they are newly made, but they do not fit while they are being used. This is because the gums and even the bones of the jaw are deformed by the added force when chewing an object. As a result, the trouble that the denture does not fit immediately arises. That is, it is not easy to solve the problem that dentures do not fit.

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

  Prior to solving the above-mentioned problems, the present inventor has come to question whether it is necessary to make a complete denture for the upper jaw especially with the upper jaw by making full use of the above-mentioned technique. Was. If the gums and bones of the body are deformed by the force of chewing on the object, it is necessary to rework the dentures exactly how they were made, and it must be repeated over and over again It is gone. Thus, the inventor has found that the upper jaw should be loose but reach well. In the following, a description will be given of a complete denture for an upper jaw, but the present invention is also applicable to a denture for a lower jaw.

  That is, the above object is achieved by providing a denture characterized in that the adhesive surface (the surface that touches the chin) has dimples that adhere to the chin. It is conceivable to attach a suction cup later if you want to get to the upper jaw well, but in reality such a margin does not exist in the upper jaw gap. Therefore, the upper jaw of the denture is provided with many dimples on the surface that is in contact with the upper jaw of the body, that is, the adhesive surface. The dimple is a dent formed on the golf ball, and is formed by molding or shaving with an electric trimmer. The number of dimples is a required number, and the shape of the mouth of the dimple is mainly circular.

To attach dimples by the above molding, carve the dimples with a reamer on the impression taken from the patient, process the dimples from this impression to make a model with protrusions as a mold, the process of making a base plate from the model, and the base plate The process of making a denture with wax and making artificial teeth with artificial teeth arrangement, the step of burying the occlusal bed after artificial teeth arrangement in a flask, heating to elute the wax and removing the base plate, and removing the wax and base plate And a step of injecting a resin into the space and copying the dimple from the projection of the model to the resin side, the method for manufacturing a denture having a dimple adsorbed to the chin on the adhesive surface . In other words, the dimples are copied to the resin from the model when performing the artificial tooth arrangement.

Further, in order to cut and attach with the above-mentioned electric trimmer, a method for manufacturing a denture having a dimple adsorbing to the jaw on the adhesive surface , including a step of applying a dimple with a reamer to the adhesive surface of the cured resin can be provided. In this method, dimples are directly attached to the adhesive surface of the resin denture base with a reamer.

  By the way, when all dentures are attached to the upper jaw, the meat on the surface of the upper jaw wet with saliva adheres closely to the dimple surface, but when the meat tries to separate because the dimple is a concave part, a negative pressure is generated in the dimple. And the meat is hard to separate. That is, the dimple acts like a suction cup. Therefore, unlike the above-described prior art, there is little need to perform the meat formation in detail, so that it can be made relatively loosely.

  Further, the above object is achieved by providing a denture having a large number of fine depressions adsorbed to the jaw on an adhesive surface (a surface in contact with the jaw). The upper jaw of the denture has a large number of fine dents on the surface of the denture that is in contact with the upper jaw, that is, the adhesive surface. The size of the fine recess is the size of various abrasives such as sand.

In order to efficiently provide the fine recesses on the adhesive surface, for example, a sandblast gun may be used. By using a sandblast gun, a fine abrasive such as alumina sand is sprayed on the adhesive surface to form a recess. That is, the present invention is a method of manufacturing a denture having a large number of fine dents adsorbed to the chin on the adhesive surface , including a step of forming a large number of fine dents on the adhesive surface by sandblasting. Alternatively, the impression may be provided with a depression as described above, and the impression may be printed on the model as a number of fine projections.

  Now, when all the dentures are attached to the upper jaw, the surface of the upper jaw wet with saliva adheres to the surface having the fine dents. Then, the adhesive force to the surface of the upper jaw is generated by many fine dents. Therefore, since it is not necessary to perform the meat formation in detail as in the above-described prior art, it is possible to make the complete denture relatively loose.

  Further, the above object is achieved by providing a denture having dimples adsorbing to the jaw on an adhesive surface (a surface in contact with the jaw) and having a large number of fine recesses adsorbing to the jaw in a portion without the dimples.

  With this configuration, both the effect that the meat on the surface of the upper jaw adheres to the surface of the dimple and the meat is hard to separate, and the effect that the meat on the upper jaw surface adheres to the surface having a fine dent to generate adhesive force, It works. Even with this configuration, since it is not necessary to form the meat closely as in the above-described prior art, it is possible to make the complete denture relatively loose.

  According to the present invention, dimples or a large number of fine dents are provided on the adhesive surface that is in contact with the jaw of the complete denture. By having the suction ability in this way, it is possible to reduce the necessity of making a denture along with the upper jaw, and it is possible to make the denture relatively loose with respect to the upper jaw.

  FIG. 2 is an explanatory diagram illustrating a perspective view of the first embodiment.   It is explanatory drawing of the manufacturing method of the complete denture 1 for maxilla.   FIG. 9 is an explanatory view of a perspective view of a second embodiment.   It is explanatory drawing of the manufacturing method of the complete denture 2 for lower jaws.   FIG. 10 is an explanatory view of a perspective view of a third embodiment.   It is explanatory drawing of the manufacturing method of the complete denture 3 for maxilla.

  1 and 2, the complete denture 1 for the upper jaw will be described. The complete denture 1 has many dimples 13 on an adhesive surface 12 of the denture base 10 on which an artificial tooth arrangement 11 is formed, which is on the side that comes into contact with the upper jaw. The dimple 13 looks like a circular depression formed on a golf ball, and is copied onto a resin by molding.

  Dimples are carved with a reamer on the side of the patient's impression that is in contact with the chin using a personal tray, and the dimple is copied from this impression to make a model with a projection as a mold (step S1). And dimples are transferred to the base plate (step S2). (However, the copy of the dimples on the base plate side at this time is not just what happens just because it is shown.) Then, wax wax is made on the base plate, and artificial teeth are arranged here to make dentures ( Step S3). Further, the occlusal bed after the artificial tooth arrangement is buried in the flask and heated to perform wax waxing, and the base plate is removed (step S4). A resin is injected into the space from which the wax and the base plate have been removed, and the pressure is reduced. Then, the dimple 13 is transferred from the projection of the model to the resin (step S5). (In this state, it is important that the dimple 13 which is a round concave portion is shown on the resin side from the model.)

  Thereafter, the resin is irradiated with microwaves in a microwave oven and heated to cure the resin, thereby completing the polymerization operation, removing the gypsum at the time of embedding and removing the resin from the model to obtain a complete denture.

  When the complete denture 1 obtained in this way is worn in the mouth, a large number of dimples 13 are provided on the adhesive surface 12 that touches the upper jaw of the complete denture 1, so that the upper denture is well attached by the suction action generated by the dimple 13. Become.

  The complete denture 2 for the lower jaw will be described with reference to FIGS. The complete denture 2 has a large number of fine depressions 23 on an adhesive surface 22 of the denture base 20 on which the artificial tooth arrangement 21 is formed, which is on the side in contact with the lower jaw of a living body. The size of the recess 23 is the size of various abrasives such as sand (sand), and is provided by sandblasting.

  Depending on when to produce the complete denture 2 for the lower jaw, sand blasting is performed, but wax wax is made on the base plate made as usual, and artificial teeth are arranged there to make the denture ( In step S6), the occlusal bed after the artificial tooth arrangement is buried in the flask and heated to carry out wax-waxing operation, remove the base plate, inject resin into the space thus formed, apply pressure (step S7), and dispose the resin in an electronic manner. The resin is polymerized and cured by microwave irradiation in a microwave oven to remove the gypsum at the time of embedding, remove the gypsum from the model, grind the back side of the floor prosthesis 20, and then perform sandblasting (step S8). . As a result, a large number of fine dents 23 having a size of sand are formed on the adhesive surface 22.

  When the complete denture 2 thus obtained is worn in the mouth, the adhesive surface 22 that touches the lower jaw of the complete denture 2 is provided with a large number of fine dents 23, so that the denture 23 is well attached to the lower jaw due to the suction action generated by the dent 23. It is.

  The complete denture 3 for the upper jaw will be described with reference to FIGS. The complete denture 3 has a number of fine dents 34 on the adhesive surface 32 of the denture base 30 on which the artificial tooth arrangement 31 is formed, which is on the side that contacts the upper jaw, and has many dimples 33 therein. Things.

  The occlusal bed which has completed the artificial tooth arrangement as usual is buried in a flask and heated, the wax is waxed, the base plate is removed, and the resin is injected into the resulting space to cure and polymerize (step S9). The gypsum at the time of embedding is removed and removed from the model, the adhesive surface 32 on the back side of the floor prosthesis 30 is polished, and sandblasting is performed to form a number of fine dents 34 of a sand grain size (step S10). Further, dimples 33 are attached to the adhesive surface 32 with a reamer (step S11).

  When the complete denture 3 obtained in this way is worn in the mouth, the dimple 33 and the concave 34 are formed by the numerous dimples 33 on the adhesive surface 32 that contacts the upper jaw of the complete denture 3 and the numerous fine depressions 34 between the dimples 33. By means of the two types of suction action produced in the above, the drug is favorably adsorbed to the upper jaw. The above two kinds of adsorption functions assist each other.

  The present invention can be sufficiently applied to dentures as joke products of party goods. In addition to dentures, dentures and the like can be configured.
