Description

TECHNICAL FIELD The present invention relates to pre-made artificial teeth used in the production of dentures, especially complete dentures.

BACKGROUND ART Artificial teeth are used in the field of prosthetic treatment in dentistry as members for producing plate dentures as treatments for patients with missing teeth.

In addition, the artificial teeth are positioned so as to restore the oral functions such as eating, speaking, and swallowing that the patient had before the teeth were lost when the dentures with dentures were made. For example, while considering the positional relationship of occlusion (occlusal relationship) and esthetics (natural view of appearance), artificial teeth of each part are placed on a temporary matrix made of wax according to the individual patient. Artificial teeth are positioned so as to form an arch shape (called a dental arch). (This operation is called arraying.)

Dentures with dentures are broadly divided into complete dentures and partial dentures. Full dentures are made for jaws with all teeth missing, and partial dentures are made for jaws with partially missing teeth. called dentures.

Many conventional artificial teeth are provided in a state in which each artificial tooth is independent in order to cope with the manufacture of not only complete dentures but also partial dentures. In the case of a partial denture and when the number of missing teeth is small, it is possible to arrange the artificial teeth by referring to the positions of the surrounding remaining teeth and opposing teeth. Although there is no particular problem in use, as the number of missing teeth increases, it becomes difficult to specify the optimum arrangement position of the artificial teeth.

In cases of complete dentures, not only are there no residual teeth to serve as a reference, but also the resorption of alveolar bone is added, and in many cases the shape of the jaw (called alveolar ridge) is flat. Therefore, specifying the optimal arrangement position of artificial teeth requires advanced knowledge and experience.

In the manufacturing process of complete dentures, as with partial dentures, the position of artificial teeth can be determined by referring to the shape of the patient's alveolar ridge and considering the position where the teeth were originally supposed to erupt. desirable. This is because, when wearing dentures, the artificial teeth harmonize with the surrounding tissue in the oral cavity, such as the tongue and buccal mucosa of each individual patient.

In addition, it is required to establish an appropriate occlusal relationship in order to obtain mechanical stability so that the denture itself does not come off from the oral cavity when the patient performs jaw movements such as mastication and pronunciation. ing. For this purpose, it is necessary to consider the contact relationship between the artificial teeth of the maxilla and mandible when the patient performs jaw movements.

However, using conventional artificial teeth that are independent one by one and arranging them in a positional relationship that satisfies the above requirements requires advanced knowledge, technology, and extremely complicated operations.

After the artificial teeth are arranged, the denture base of the wax denture is replaced with a resin such as acrylic from wax, and polymerized. This operation causes distortion and deformation of the denture itself due to polymerization shrinkage of the denture base material, and misalignment of the individual artificial teeth. Although the optimal occlusal relationship is established by this, the current situation is that the operation is very complicated and takes time.

In response to this situation, several attempts have been made in the past to reduce the technical difficulty and the arrangement work time.

Patent Literature 1 describes what is called a fully arched plastic artificial tooth. The artificial tooth described in Patent Document 1 is provided with a support between the spaces of the U-shaped structure and by defining the gradient of the crown axial surface for facilitating the division of the mold. It enables the production of artificial teeth that resemble natural human teeth.

However, Patent Document 1 does not specifically disclose the shape of the dental arch of the connected artificial tooth. In addition, the occlusal contact relationship between the maxillary artificial teeth and the mandibular artificial teeth is unclear, and the appropriate occlusal relationship cannot be secured as a set of the maxillary artificial teeth and the mandibular artificial teeth. complicated operation is required.

As a result, it cannot be said that dentures that function in the oral cavity of patients are necessarily provided.

(Findings on which this disclosure is based)
In order to solve the problem, the present inventors have developed a method that can be applied to the shape of the alveolar ridge of an unspecified number of edentulous patients, and that has both left and right central incisors, lateral incisors, canines, first premolars, and third teeth. A pair of connecting artificial teeth for the upper and lower jaws, in which all 14 teeth of two premolars, first molars, and second molars are connected in an ideal dental arch shape and in an ideal occlusal contact relationship between the upper and lower jaws. Considered the set.

More specifically, in the step of providing the connected artificial teeth, the shape of the dental arch of the connected artificial teeth, that is, the appropriate arrangement position of the artificial teeth in all parts is clearly defined three-dimensionally, At a minimum, clearly define the contact points that should be secured between the connecting artificial teeth for the lower jaw and the connecting artificial teeth for the mandible. When manufacturing a complete denture using an average value articulator, the amount of reduction adjustment is small, and in order to easily establish a bilateral balanced occlusion, the maxillary central incisor part, maxillary Lateral incisors, maxillary canines, maxillary first premolars, maxillary second premolars, maxillary first molars, and maxillary second molars, and mandibular central incisors in connected artificial teeth for the mandible The occlusal facets of the teeth, mandibular lateral incisors, mandibular canines, mandibular first premolars, mandibular second premolars, mandibular first molars, and mandibular second molars are occlusal planes. and set the angle appropriately. In addition, the contact position relationship of each occlusal facet in the cusp-to-cuspid position between the maxillary connected artificial tooth and the mandibular connected artificial tooth, the working side and balance side in lateral movement in the eccentric position, and each during forward movement Appropriately set the gliding relationship of the occlusal facets.

Among the above problems, the present inventors conducted the following investigations in order to find an ideal dental arch shape that harmonizes with edentulous patients regardless of the difference in alveolar ridge shape.

As described in Technical Background, there is a view that it is desirable to determine the arrangement position of artificial teeth by referring to the shape of the patient's alveolar ridge and considering the position where the teeth are supposed to have erupted from the beginning. In reality, however, even complete dentures fabricated based on this idea rely on the knowledge and experience of skilled operators to determine the position of the artificial teeth. There is no evidence that it actually matches the position.

Therefore, we measured the eruption positions of the natural teeth in each part of the model that replicated the lower jaw of an edentulous person with no defects, that is, the shape of the dental arch, and placed them in the XYZ orthogonal coordinate system under certain conditions. The time distribution was analyzed statistically.

Measurement was performed using a three-dimensional shape measuring machine. The lower jaw natural tooth model is arranged with respect to the XYZ orthogonal coordinate system so that the origin of the XYZ orthogonal coordinate system and the measured lower jaw incisor point of the natural tooth row are at an X coordinate value of 0 mm, a Y coordinate value of 0 mm, and a Z coordinate value of 0 mm. match. The natural tooth model of the mandible is arranged so that the Z coordinate value of the distal buccal cusps of the mandibular first molars arranged on the left and right sides is 0 mm. In addition, the left portion of the natural tooth model of the lower jaw is arranged on the positive (+) X coordinate value side, and the right portion of the natural tooth model of the lower jaw is arranged on the negative (−) X coordinate value side. . The absolute values of the X-coordinate, Y-coordinate, and Z-coordinate of the incisal edges of the incisors and canines of the left part of the natural tooth model of the mandible, and the cusps of the molars, and the right side of the natural tooth model of the mandible The natural tooth model of the mandible was arranged so that the absolute values of the X-, Y-, and Z-coordinates of the incisal edges of the incisors and canines and the cusps of the molars in the site were equal to each other. .
As a result of the analysis, it was found that the distribution of the eruption position of the edentulous subjects with no defects showed little deviation due to individual differences.

Next, we measured and statistically investigated the arrangement positions of artificial teeth implanted in complete dentures used by edentulous patients. This complete denture is based on the idea of arranging the artificial teeth at the position where the teeth are thought to have erupted from the beginning, and the patient's satisfaction is also obtained.
As a result of the analysis, it was also found that there is little deviation in the arrangement position of the artificial teeth due to individual differences among patients.

As a result of analyzing the distribution of the eruption positions of the natural teeth and the distribution of the arrangement positions of the artificial teeth implanted in the complete dentures, it was found that the two were roughly the same. For this reason, it was proved that the complete dentures manufactured by the method of arranging the artificial teeth in the positions where the teeth were originally erupted were arranged in the positions where the teeth were erupting with a high probability. It was suggested that it is possible to fabricate a satisfactory complete denture.

Therefore, based on the distribution of these dental arches, artificial teeth for each part are arranged within a range constituted by a constant quadratic function curve in virtual three-dimensional coordinates, and connected artificial teeth for the upper jaw are arranged. If we provide a set of connected artificial teeth in which the connected artificial teeth for the lower jaw are in a state where static stability is secured, functional complete dentures can be manufactured in a short time regardless of the skill of the operator. , and thought that it would be applicable to a large number of unspecified edentulous patients, and arrived at the present invention.

Next, three operators with different years of experience applied the upper and lower jaw interlocking artificial tooth sets of Examples 1 and 2 and Comparative Examples 1 and 2 to three edentulous jaw models with different shapes and sizes. were used to prepare complete dentures according to the common method.
The operators were operator a, operator b, and operator c in descending order of years of experience in manufacturing complete dentures.
For the patients, the edentulous jaw model M1, the edentulous jaw model M2, and the edentulous jaw model M3 were arranged in descending order of the size of the jaw in appearance.

About the time required for artificial tooth arrangement,
The articulator used was an average value articulator (Handy IIA, manufactured by Shofu Co., Ltd.). The upper and lower jaw interlocking artificial tooth sets of Examples 1 and 2 and Comparative Examples 1 and 2 are arranged on the occlusal support prepared on the basis of the occlusal plane plate by operator a, operator b, and operator c. We measured the time required to complete the

Table 1 shows the evaluation results of the time required for arranging the artificial teeth.

When the upper and lower jaw interlocking type interlocking artificial tooth set of Example 1 is used, when the upper and lower jaw interlocking interlocking artificial tooth set of Example 2 is used, and when the interlocking artificial tooth set of Comparative Example 1 is used , and the case of using the connected artificial tooth set of Comparative Example 2, the time required for the arrangement operation is clearly shorter.
In addition, when using the same set of connected artificial teeth, it can be seen that there is little variation due to the difference in years of experience of the operator.
From this, the maxillomandibular fitting type connected artificial tooth set of the present invention is capable of arranging artificial teeth in a short time regardless of the skill of the operator and the difference in the alveolar ridge shape of edentulous patients. It suggests.

Next, the contact state of each part of the connected artificial tooth set in the intercusp position on the articulator, and each part of the connected artificial tooth set when moving laterally and forwardly along the guide path of the articulator. The degree of perfection of the occlusal contact state was evaluated for the contact state of
The degree of perfection of the occlusal contact relationship was subjectively evaluated by the operator's visual observation in three grades of "A", "B", and "C". "A" is a state in which the alveolar ridge shape on the model is in harmony with the subjective view of the operator, and bilateral balanced occlusion has been established. "B" is in harmony with the alveolar ridge shape on the model, and bilateral balanced occlusion has been established, but there is no contact in all regions. "C" is a state that does not match the alveolar ridge shape on the model according to the operator's subjective opinion, or that static stability in the cusp-to-cuspid position is not obtained.

Table 2 shows the evaluation results of the degree of perfection of the arrangement state on the articulator.

When the upper and lower jaw interlocking type interlocking artificial tooth set of Example 1 is used, when the upper and lower jaw interlocking interlocking artificial tooth set of Example 2 is used, and when the interlocking artificial tooth set of Comparative Example 1 is used , and the case of using the connected artificial tooth set of Comparative Example 2, it can be seen that the degree of perfection is clearly high.
In addition, the degree of perfection of the arranged state is higher in the case of using the upper and lower jaw interlocking type interlocking artificial tooth set of Example 2 than in the case of using the upper and lower jaw interlocking interlocking artificial tooth set of Example 1. I know.
It can be seen that when the connected artificial tooth set of Comparative Example 1 is used, the degree of perfection is low in any of the examples.
When the connected artificial tooth set of Comparative Example 2 is used, the shape of the dental arch is the same as that of the upper and lower jaw fitting type connected artificial tooth set of Example 1. Therefore, the dental arch corresponds to the ridge shape of the edentulous model. However, most of them were not able to establish bilateral balanced occlusion, and the degree of perfection was low in all conditions.
From this, the maxillary and maxillomandibular interlocking artificial tooth set of the present invention can be completed more easily than the conventional connecting artificial teeth, regardless of the skill of the operator and the difference in the alveolar ridge shape of the edentulous patient. A high degree of alignment is possible, suggesting that an ideal occlusal contact relationship can be established.

The main purpose of the present invention is to use it for a complete denture, but it is not necessarily limited to the use of a complete denture, and it is possible to use only one of the upper and lower jaws, or to use a partial denture with a large number of teeth missing. It is also effective to use when making dentures by combining complete dentures.
For example, in a case where all the incisors and canine teeth remain in the upper jaw and all the molar teeth are missing, whereas the lower jaw is missing all the teeth, the canine part of the maxillary joint artificial tooth of the present invention and the It is also possible to divide between the first premolars and use only the molars. At this time, since the maxillary molars are secured to fit with the mandibular molars, it is possible to manufacture good dentures in a shorter time than conventional artificial teeth in which each tooth is independent. .

In addition, as the population ages, the number of patients who find it difficult to go to a dental clinic is expected to increase. It is conceivable that there will be a need to fabricate dentures or repair artificial teeth. The present invention can be expected to be easily applied to such situations.
