Description

  The present invention relates to a ready-made standard denture base and standard denture having a predetermined shape and having artificial teeth arranged at a predetermined height. The present invention also relates to a denture preparation kit including the reference denture base and the reference denture. Furthermore, the present invention relates to a method for producing a denture using the denture production kit.

2. Description of the Related Art Conventionally, dentures are mainly manufactured by the following procedure.
(1) An impression in the oral cavity of a patient is obtained using an impression material.
(2) A plaster model is prepared using the impression.
(3) The occlusal bed is attached to the patient to obtain the occlusion.
(4) Arrange artificial teeth on the occlusal bed to produce wax dentures.
(5) Try the wax denture on the patient and adjust the occlusion.
(6) The mold is made by burying the wax denture in the plaster.
(7) A resin is injected into a mold and cured to produce a denture.

  As described above, since the dentures are manually manufactured one by one according to the shape of the oral cavity of the patient, a large amount of time is required, and the burden on the dental clinic, the dental laboratory, and the patient is large. In addition, since the method for manufacturing a denture includes a plurality of transfer steps, a shape error is likely to occur. Furthermore, the quality tends to fluctuate depending on the skills of the dentist and the dental technician.

  Patent Document 1 discloses a method of manufacturing a denture using a denture base mass-produced using a mold or the like. Patent Document 2 discloses a method for producing a denture using a prosthetic denture precursor in which at least one artificial tooth is arranged in a denture base member made of a plastic photopolymerizable composition. Although these methods can simplify some of the steps, it is still difficult to say that the method is sufficiently simplified because a gypsum model still needs to be prepared. In addition, denture bases made based on the oral shape of edentulous persons have difficulty in mass-producing the denture base in a predetermined shape because the absorption of the alveolar crest differs for each patient.

  Conventional denture manufacturing methods are generally manufactured based on the alveolar crest line rule, but as described above, such a denture manufacturing method has a problem that it is complicated. Furthermore, in the present age when patients are aging, it is difficult to obtain a normal occlusion when the dentures produced by the above method have remarkable retraction of alveolar bone, and problems such as cross occlusion have arisen. Therefore, in recent years, a denture manufacturing method based on a denture space theory that determines a denture shape in accordance with a muscle pressure neutral zone which is considered to have a dental arch at the time of a dentition has been proposed. However, it takes a lot of time to learn a denture manufacturing method based on the denture space theory. Further, even with a denture producing method based on the denture space theory, the denture producing method itself is complicated as in the related art. Therefore, there is a need for a denture based on the denture space theory, which can be manufactured by a simple method.

  An object of the present invention is a ready-made standard denture base or standard denture which can be adapted to many patients, has a denture base of a predetermined shape, and has a length (height) perpendicular to the tooth axis of the artificial tooth. Is to provide a standard denture base or a standard denture defined in a predetermined range. Another object of the present invention is to simplify the denture preparation process using the reference denture base or the denture preparation kit including the reference denture, thereby shortening the preparation time of the denture.

  Means for Solving the Problems In order to solve the above problems, the present inventors have determined to determine the shape of a denture based on the shape of the oral cavity of a dentulous person and an edentulous person, and to produce a denture based on the shape. Then, a reference denture base having a predetermined shape was produced by this method. Further, artificial teeth were arranged at predetermined positions on the reference denture base at a predetermined height. It has been found that a reference denture base or reference denture of a predetermined shape produced in this way is applicable to many edentulous people. Furthermore, by using this standard denture base or a denture preparation kit including the standard denture, it has been found that the denture preparation process can be simplified while maintaining a high compatibility rate, and the present invention has been completed. .

  The present invention for solving the above problems is as described below. In the specification of the present application, the reference denture base refers to a denture base that is a ready-made denture base in which all of the artificial teeth are not arranged. Unlike the conventional denture base, which is individually made by taking an impression of the oral shape of the patient individually as in the past, the reference denture base of the present invention statistically determines the oral shape of the dentulous person. It is made based on the denture space theory. Therefore, if several types of standard denture bases are prepared, a denture with a high degree of conformity can be manufactured for almost all patients by laying the lining material and arranging artificial teeth, and absorbing the alveolar crest. Can be adapted to patients with severe difficult cases. In the present specification, the entire dentition refers to a dentition including 14 teeth from the left second molar to the right second molar.

  Since the reference denture base or the reference denture of the present invention has a predetermined shape, it can be easily adapted to the shape of the oral cavity of the patient only by laying the lining material. That is, in the conventional denture manufacturing process, the time required for manufacturing the denture can be reduced by using the ready-made denture base. Further, in the reference denture base of the present invention, since a part of the artificial teeth is arranged at a predetermined position, the arrangement time of the artificial teeth can be reduced. Thereby, the burden on the dentist, the dental technician and the patient can be significantly reduced.

  Since the standard denture base or the standard denture of the present invention is statistically determined based on the denture space theory and the oral shape of the dentulous person is prepared, it is necessary to prepare several types of the standard denture base or the standard denture. Thus, a denture with a high precision can be manufactured for almost all patients. It can also be applied to patients with difficult cases in which absorption of the alveolar crest is severe.

Reference numeral 101 denotes an artificial tooth. When all the dentitions are arranged on the reference denture base, the denture is completed.

  In FIG. 1A and FIG. 1B, point O is a point corresponding to the upper lip zone corresponding to the median of the floor edge of the labial side, and point P is equivalent to a left wing protrusion maxillary notch at the posterior edge of the floor. It is a point to do. The left buccal floor edge 50 of the maxillary reference denture base 100 has points D1 to D3 (described later). Point o is a point corresponding to the lower lip zonule in the middle of the floor margin on the lip side. Point p is a point corresponding to the left posterior ridge on the posterior edge of the floor. The left buccal floor edge 52 of the lower jaw reference denture base 200 has points d1 to d3 (described later). In the reference denture base of the present invention, the relative positional relationship of these points is within a predetermined range. Further, at least a pair of the first molar, the central incisor, or the canine is arranged in advance at a predetermined position and height of the reference denture base.

Point P is a point corresponding to the left wing protrusion maxillary notch at the floor trailing edge, and point Q is a point corresponding to the right wing protrusion maxillary notch at the floor trailing edge. The point M is a middle point of a line segment PQ connecting the point P and the point Q. In this reference denture base, when the length of the line segment PQ is 1, the length of the line segment OM connecting the point O and the point M is in the range of 0.76 to 0.98, and 0.81 to 0.81. It is preferably in the range of 0.93, and more preferably in the range of 0.86 to 0.88.

(Denture preparation kit)
The denture preparation kit of the present invention includes an upper-standard denture base or an upper-standard denture, a lower-standard denture base or a lower-standard denture, and may include a lining material and a connecting artificial tooth. When using a standard denture base, a denture is manufactured by laying a lining material so as to conform to the shape of the oral cavity of a patient and arranging artificial teeth.

  In the denture preparation kit of the present invention, it is preferable to prepare in advance a plurality of upper standard denture bases or upper dentures having different sizes, and a lower standard denture base or lower denture base. Thereby, the adaptation rate to the patient can be further increased. The upper denture base or upper denture, the lower denture base or lower denture preferably have 2 to 10 types, more preferably 2 to 5 types, and more preferably 3 to 3 types. It is particularly preferable to prepare the types.

A method for preparing a denture using the denture manufacturing kit of the present invention will be described below.
First, an upper reference denture or upper denture and / or a lower reference denture or lower reference denture that match the oral size of the patient are selected. Such selection of the reference denture base or the reference denture can be determined based on the measurement of the oral cavity size. As a method of measuring the oral cavity size, a known method can be used, and examples thereof include measurement by visual inspection and palpation, and measurement of the size by trial fitting of an impression tray. When the reference denture base is selected, the artificial teeth are arranged on the selected upper reference denture base and lower reference denture base, respectively, to produce the upper denture and the lower denture. In addition, the upper and lower dentures are each provided with a lining material to be perfectly adapted to the shape of the patient's mouth. Either the arrangement of the artificial teeth or the embedding of the lining material may be performed first. The bite is then adjusted, if necessary, after being tested on the patient's mouth. As a result, a denture matching the shape of the oral cavity of the patient is produced.

  Known materials for the standard denture base in the present invention can be used without any limitation. Specifically, methyl (meth) acrylate, ethyl (meth) acrylate, isopropyl (meth) acrylate, n-propyl (meth) acrylate, butyl (meth) acrylate homopolymer or at least a copolymer thereof. One selected poly (meth) acrylate-based resin, polyolefin-based resin (eg, polypropylene), polyamide-based resin (eg, Nylon 66 (registered trademark)), polyester-based resin (eg, polycarbonate), polyether-based resin ( For example, polyacetal, polysulfone), polynitrile-based resin (eg, polyacrylonitrile), polyvinyl-based resin (eg, polyvinyl acetate), cellulose-based resin (eg, cellulose acetate), fluorine-based resin (eg, polychlorofluoroethyl) Emissions), imide-based resins (e.g., an aromatic polyimide), and the like.

  The reference denture base in the present invention may contain a filler in order to improve the strength of the denture base. The filler may be an organic filler or an inorganic filler. Alternatively, a granular organic-inorganic composite filler obtained by adding a polymerizable monomer to an inorganic filler in advance, forming a paste, polymerizing, and pulverizing the paste may be used.

  A part of the reference denture base in the present invention may be formed of metal.

  The standard denture base in the present invention can be manufactured by a known molding method. For example, injection molding, compression molding and the like can be mentioned.

Known lining materials can be used without any limitation. For example, the above-described poly (meth) acrylate-based resin described as the material of the standard denture base, and polyolefin-based resin, polyamide-based resin, polyester-based resin, polyether-based resin, polynitrile-based resin, polyvinyl-based resin, cellulose-based resin, Fluorine-based resins, imide-based resins, silicone resins, and the like are included.
As the lining material, a known material may be appropriately selected depending on the purpose of use. For example, in the case where the patient performs the treatment for a relatively short period of time of one to several days, the back, which is a powdery, creamy, or seal-like denture base fixing material (so-called denture stabilizer). Equipment can be selected. Further, as the lining material, a dental mucosal conditioner, a soft lining material, and a hard lining material to be operated by a dentist can be selected. If the oral mucosa has ulcers or inflammation and is used until the oral mucosa is restored to a healthy state while relieving pain, a durometer A hardness of 55 or less lining material (dental mucosal conditioner and soft Lining material) can be selected. Usually, a material used for one to several weeks is a dental mucosal conditioner, and a material used for a long period of six months or more is a soft lining material. The physical properties of both the dental mucosal conditioner and the soft lining material are defined by JIS standards. Further, when it is desired to adhere more firmly and improve the durability, a hard lining material having a Knoop hardness of 7 Hk or more (JIST6521 (hard lining material for denture base)) can be selected.

  In the present invention, known artificial teeth made of resin or ceramic can be used as the artificial teeth. Examples of the resin-made artificial teeth include the above-mentioned poly (meth) acrylate resin, and polyolefin resin, polyamide resin, polyester resin, polyether resin, polynitrile resin, polyvinyl resin, cellulose resin, and fluorine resin. An artificial tooth made of a resin, an imide resin, a silicon resin, or the like is exemplified. As the artificial tooth, a connected artificial tooth in which two or more artificial teeth are connected and integrated can also be used. As a method for fixing the artificial tooth, conventionally known methods such as fitting and bonding can be used without any limitation.

(Accuracy)
In this example, the fitting rate was evaluated based on the ratio of the number of matching models when trial-fitting 20 kinds of edentulous full-jaw models having different shapes after lining the standard denture base.
