(Points of interest)
Japan is now aging faster than any other country in the world, and many elderly people are required to maintain their health and improve their quality of life. One of the most important social needs in dentistry can be cited as an indispensable element for promoting healthy oral intake of nutrition and maintaining mental and physical health.
In this situation where demand is increasing, the current state of complete denture manufacturing using artificial teeth must have both the aesthetics of the front teeth and sufficient masticatory functionality in harmony with the gender and appearance of each patient. However, the manufacturing process becomes complicated, and a great deal of labor is required until completion.

    For example, a general method for manufacturing a complete denture is to first create an upper and lower jaw base floor based on an upper and lower jaw model obtained from a functional impression from an upper and lower edentulous patient to be treated. After connecting the occlusal embankment materials of standard dimensions to build up the upper and lower jaw occlusal floors, they are mounted on the upper and lower jaw ridges in the patient's oral cavity, and the occlusal height, the size of the dental arch, the front teeth Place the maxillary occlusal floor on the articulator occlusal plane plate in the upper and lower occlusal floor (bank) where the position of the upper and lower jaws is recorded and adjust the position, etc. The midline of the maxillary model coincides with the midline of the occlusal plane plate, and the molar teeth of the maxillary occlusal ridge are positioned to match the standard maxillary dental arch shape. The upper jaw model is fixed to the upper arch of the articulator with plaster.

    Furthermore, after removing the occlusal plane plate, aligning the upper and lower jaw occlusal floors, fixing the lower jaw model to the appropriate position of the articulator lower arch, again removing the lower jaw model from the lower level of the articulator, attaching the occlusal plane plate to the appropriate position, Artificial teeth are selected by comprehensively considering the patient's gender and appearance, mastication, swallowing function and aesthetics (recovery of pronunciation function), and the necessary range of occlusal ridges to the ground by one tooth or multiple teeth In order not to lose the reference (occlusion plane, occlusal high diameter) while removing only the mechanical consideration according to the law of the alveolar line in accordance with any occlusal style, the artificial dental arch shape is tongue, cheek, etc. The placement of each artificial tooth, tooth axis angle, orientation, etc., including various elements, such as setting a suitable width and long diameter at a position called a neutral band that does not alienate the movement of muscles and soft tissues Observe and line up with corrections It must go through a complex process called.

    In this way, three-dimensional arrangement with respect to the articulator, inclination of each tooth axis, torsion, and the work of softening and arranging the wax one by one for 28 artificial teeth while taking into consideration aesthetic factors Is very cumbersome and requires not only a lot of time and effort, but also requires high skill and high skill, so that individual dental technicians can arrange hundreds of people and thus the desired occlusal mode Therefore, it was difficult to objectively verify whether each artificial tooth was properly arranged, and it was very difficult to stabilize the denture quality and to produce it efficiently.

(Conventional technology)
As a measure to overcome this, the lower and upper arches of the articulator are fitted with gypsum models of the lower jaw and the upper jaw, and the position of the transparent plate on which various reference lines are drawn is restricted to the occlusal surface of each gypsum model. Support means are provided on the lower arch and the upper arch, respectively, and the wax bed of the artificial tooth array in which the artificial teeth are arranged and fixed in advance on the wax bed is softened and adjusted so that its curvature matches the reference line on the transparent plate. The artificial tooth is fixed to a transparent plate, and molten wax is injected into the gap between the wax bed and the maxillary plaster model, and the wax bed is shaped to obtain an upper wax base denture, while the artificial teeth are fixed to the wax bed in advance. Using the prepared artificial tooth array, make a lower denture base denture that properly meshes with the upper base plaster model of the upper plaster model on the lower plaster model, and replace the wax base of the base plaster with a resin floor to obtain a denture So that the artificial teeth are neatly planted in appropriate positions and the dentures with good occlusion are Skilled The requiring not the set as the efficiently be manufactured by techniques (e.g., see Patent Document 1) is proposed.

    In addition, while maintaining the anatomical positional relationship between the upper and lower molar artificial teeth, the upper molar artificial teeth and the lower molar artificial teeth have a protruding portion, and a supporting portion is formed on the protruding portion, and the upper molar artificial teeth and lower molars The artificial teeth are arranged in a dental prosthetic positional relationship, and in the denture manufacturing process, the artificial tooth arrangement can be simplified and the working time can be greatly shortened. A dental prosthesis can be easily prepared while adjusting and determining the intermaxillary distance (for example, see Patent Document 2), or an artificial tooth arrangement device is attached to a predetermined part of the articulator. A tooth shifting device is provided, and the shifting device can be adjusted at least one of an inclination angle and an upper and lower level. According to the general An arrangement in which arrangement according to the row theory can be performed efficiently (for example, see Patent Document 3), and artificial teeth formed by movable softening wax are implanted in the floor wax on the occlusal floor to produce a wax denture. After that, the artificial tooth is replaced with a hard artificial tooth so that the arrangement of the artificial teeth in the oral cavity of the patient can be facilitated, and the working time of the dentist and dental technician can be shortened. (See, for example, Patent Document 4).

However, in the former (Patent Document 1), it is necessary to provide support means for the transparent plate in each of the lower jaw model bow and the upper jaw model frame of the articulator, and the third one (Patent Document 3) An artificial tooth arrangement device with a shift device for artificial teeth is added to the basic components of the articulator, both of which are not widely added to the widely used articulators. In order to connect to the manufacture of dentures economically with the disadvantage that efficient denture production cannot be carried out, modifications and additional parts are attached to conventional articulators or new ones with special parts are attached. The second one (Patent Document 2) has a joint where the upper and lower artificial teeth are detachable, and is in a dental prosthetic positional relationship at the time of joining. The upper and lower joint artificial teeth that are regulated to be placed There is a disadvantage that the artificial teeth supplied in general cannot be used as they are, and if the market is not ready for mass production and supply of artificial teeth with such special structures, economical implementation will not be possible. In addition, the last technology (Patent Document 4) is a process of making dentures in the process of making dentures, matching 28 artificial teeth of upper and lower teeth made of movable softening wax with ready-made artificial teeth. A total of 128 teeth must be manufactured one by one, and there is a concern that all of them will require a lot of man-hours, and it is necessary to produce and store a large number of artificial teeth made of movable softening wax. While reducing the man-hours for tooth position adjustment work, the work man-hours for manufacturing movable softened wax artificial teeth increase, leaving the drawback that it is difficult to increase the overall work efficiency of denture production There was.

(Awareness of problems)
As mentioned above, denture manufacturing technologies such as various prosthetic devices and prosthetic manufacturing methods that have been proposed in the past have been improved by adding precision parts that can serve as a standard for artificial tooth arrangement to the articulator. To improve the efficiency of tooth arrangement work, or to connect artificial teeth in an arranged state in advance to improve the workability of arrangement work, or to arrange artificial teeth made of movable softened wax A variety of products have been developed, including a technology to manufacture dentures by finally replacing them with commercially available hard artificial teeth, but all of them use existing general articulators and commercially available artificial teeth as they are. It has the disadvantages that it cannot be used and implemented, increases the economic burden, and does not have a significant effect on reducing the labor burden of denture production. Only equipment and dental materials Using a technique that can be produced economically and efficiently dentures is the current situation that not yet exist.

Depending on the shape of the maxillary artificial denture of the maxillary wax denture, which is produced by deforming and responding to the standard negative mold for the dentition, the negative mold for determining the occlusal fitting position is also weakened Can be easily and accurately fitted by deforming the upper part, and the mandibular prosthetic dentition (for determining the occlusal dentition) that is integrally engraved in accordance with the arch shape Ditch) The arcuate shape is deformed in the same way, and an accurate occlusal fitting position can be obtained. What had to spend a great deal of effort and time to obtain the proper occlusal position of the tooth group would alleviate these workloads and improve the productivity of upper and lower jaw wax dentures at once. It can be.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The wax dentures are manufactured using a standard negative model for artificial dentition made of elastic material on the occlusal flat plate of the articulator, and the midline is the incisor guidance nail and incisor guidance. Position and place it so that it matches the apex of the mark and the left and right ends of the maxillary molars match the alveolar line law, and connect the maxillary artificial teeth according to the tooth arrangement in the standard negative mold groove for the artificial dentition After fitting and fitting, the appropriate amount of the softened occlusal levee is attached to the upper floor of the upper jaw. At the same time, the upper arch of the articulator is closed so that the incisor guidance nail contacts the incisor guidance plate, and occlusion After obtaining the maxillary wax denture by integrating the levee between the maxillary foundation floor and the maxillary artificial tooth group, open the articulator, and remove the occlusal plate and the standard shade for the artificial dentition into the lower arch An occlusal fitting made of an elastic material set to a standard dental arch shape, fixing the mandibular model to which the mandibular foundation floor is attached The decision-type negative reference dentition insertion groove is inserted into the maxillary wax denture artificial dentition, and the mandibular artificial tooth according to the arrangement of teeth in the occlusal dentition determination mold groove for determining the occlusal fitting position After fitting and fitting, the appropriate amount of the softened occlusal levee is mounted on the lower mandibular floor, and at the same time, the upper and lower arches of the articulator are closed so that the incisor guidance nail contacts the incisor guidance plate. The occlusal levee material is integrated so as to be sandwiched between the mandibular foundation floor and the mandibular artificial tooth to obtain a mandibular wax denture. After obtaining the lower jaw denture first, after fitting the reference denture groove into the lower jaw artificial dental row and attaching the negative mold for determining the occlusal fitting position, the same occlusal fitting After disposing and fitting the maxillary artificial teeth in a concatenated manner according to the tooth arrangement in the occlusal dentition determining mold groove for positioning determination, The 該咬 Gotsutsumi integrally combined closed articulator as to sandwich between the maxillary baseplate and maxillary artificial teeth, it is possible to set so that through the process of obtaining maxillary wax denture.

    At any stage during the manufacturing process of the upper and lower jaw dentures, you can freely perform operations such as attaching and detaching the upper and lower jaw base floor as needed, opening and closing the articulator, or upside down as needed. If the work procedure can be carried out substantially equivalently even if the order of each work process is changed, the work procedure can be moved back and forth, for example, the proper position on the occlusal plane plate In the process of placing the upper jaw model with the upper jaw occlusal floor and fixing it to the upper arch of the articulator, the upper jaw occlusal floor is placed at the appropriate position on the occlusal plane plate, and then the upper jaw model is attached to the articulator upper arch. If there is a possibility that the work efficiency may be slightly changed by changing the process before and after the process, a more efficient work procedure should be selected. Combines and hardens each foundation floor and artificial teeth From immediately after, in any stage of until the upper and lower jaws wax denture is completed, it can be shaped so that it can ensure the aesthetic and chewing property to give a gum-like appearance.

    The standard denture for artificial dentition is accurately arranged to arrange the artificial teeth for the corresponding jaw in a standard dental arch shape according to any occlusal style for one of the upper and lower jaws. More specifically, the standard arrangement of the maxillary artificial teeth group attached to an appropriate position on the occlusal plane plate of the articulator and the target upper basement floor attached to the maxillary model, for example, is set. It functions to enable accurate and quick guidance and determination, and the whole makes it possible to easily and accurately hold a group of artificial teeth composed of a plurality of artificial teeth. It is made of an elastic material made of various synthetic resins such as silicon resin, natural rubber, synthetic rubber, urethane resin that can be easily detached after bonding and can be used multiple times. A horseshoe shape corresponding to the foundation floor The groove for positioning the artificial dentition in the wall thickness from the top surface to the bottom surface opposite to the bottom surface coincides with the occlusal plane, with respect to the occlusal plane and condyles of the articulator. Standard maxillary dental arch shape according to the occlusal style, it should be engraved so that it can be arranged in an articulated manner, and it can be expanded, contracted and deformed freely according to the size and shape of the individual ridge It is preferably made of a dental material having sufficient elasticity and colorless and transparent or colored and transparent elasticity.

    In addition, in order to obtain a standard negative mold for artificial dentition that can realize a higher accuracy of artificial tooth arrangement, the cut edge of each artificial tooth and the necessary part of the occlusal surface coincide with the occlusal plane at the appropriate bottom of the mold groove. In order to make the artificial teeth contact the occlusal plane plate more reliably, the through window is opened slightly larger than the actual contact area. In addition, the occlusal occlusal plane should be installed so that it does not interfere with the tip of the incisor guidance nail of the incisor guidance nail when the articulator is mounted at an appropriate position on the occlusal plane plate and closed. Depth that penetrates from the top surface to the bottom surface and reaches the mold groove at the lip side between the maxillary central incisors corresponding to the incisal guidance index tip when the bottom surface is mounted at a predetermined location on the face plate The middle line positioning groove is engraved, and the innermost To each of the rear corresponding points of the teeth, it is preferable assumed that temporary fixing mechanism is incorporated to enable the positioning and temporary fixing the articulator occlusal plane board.

    The bottom surface of the standard dental mold for artificial dentition enables the positioning of the standard dental mold for artificial dentition on the articulator occlusal plane plate in a stable and accurate manner, and the position of the top surface of the occlusal plane plate and the mold groove for the artificial tooth group It must function to maintain the relationship precisely, and it must be able to secure a sufficient joint area with the upper surface of the occlusal plane plate, and it should be finished to a smooth surface that can adhere to the occlusal plane plate surface. In addition, the upper surface of the standard negative mold for the artificial dental dentition should have a shape that does not interfere with the foundation floor (bank) when attempting to arrange the artificial dental dentition. It is advantageous to set the alveolar surface at a position closer to the ridge surface or cheek surface of each artificial tooth than the maximum bulge portion of the tongue surface so as to realize stable maintenance.

    The standard negative mold for the artificial dentition is either the left or right posterior end outer wall, or the upper molar group on either the mold groove range for the left or right maxillary molar artificial tooth group to the left or right posterior end outer wall. The left and right alveolar crest line display sections that indicate the position of the alveolar crest line, and the left and right mandibular prosthetic surface display sections that match the left and right pound lines should be displayed, respectively. Provide the second molar back edge display part at the position corresponding to the rear edge of the left and right second molars on the left and right buccal outer wall of the standard negative type for artificial dentition, or artificial anterior teeth on the lip side or left and right buccal side outer wall Desirably, the second molar back edge display band is displayed over a range from the tooth group to the second molar rear edge of each of the left and right maxillary molar artificial teeth, Alveolar crest line display part, Mandibular artificial tooth surface display part, Second molar back edge display part, Second molar Okuen display zone, both engraving, printing, seal attached, preferably set to those clearly displayed by any such entry.

    The temporary locking mechanism accurately positions the left and right back posterior molars of the standard denture for artificial dentition placed in place on the articulator occlusal plane plate with respect to the occlusal plane plate.
