Description

  The present invention relates to a connected artificial tooth row formed by connecting a plurality of artificial teeth used in an implant.

  For people who use dentures, dentures function as part of the body and are indispensable for living daily life. In addition, since superstructures such as dentures function daily in the oral cavity, their consumption is severe, and it is necessary to perform maintenance for a certain period of time and to replace them with new superstructures.

  Patent Document 1 discloses an invention related to a temporary prosthesis of a denture and an implant, and a connecting tooth of a final prosthesis. This is because a plurality of artificial teeth are connected by a connecting material, and the plurality of artificial teeth can be arranged together when the artificial teeth are fixed to the denture base.

JP-A-6-261919

  There is a so-called implant treatment in which an artificial tooth root (implant) is embedded in a jawbone, an abutment functioning as a connecting member is attached to an end portion of the artificial tooth root disposed inside the oral cavity, and an artificial tooth is attached thereto. A more convenient artificial tooth used for such implant treatment is also demanded. However, in the prior art, such examination has not been made on implants.

  In view of the above problems, an object of the present invention is to provide a highly convenient connected artificial dentition used for an implant.

  The present invention will be described below. Here, for ease of understanding, reference numerals of the drawings are given in parentheses, but the present invention is not limited to this.

  In one aspect of the present invention, a plurality of resin-made artificial teeth (11) are integrally connected, an occlusal surface (11a) is formed on one surface, and the surface opposite to the occlusal surface is formed. Is a connection artificial tooth row (10) provided with a hole (12) into which a connection member with the artificial tooth root is to be inserted. Here, examples of the “connecting member with the artificial tooth root” include an abutment and a cylinder connected to the artificial tooth root.

  The holes (12) of the connected artificial teeth row (10) can be provided in all artificial teeth (11).

  The artificial tooth (11) is a resin material, and may be formed of a polymethyl methacrylate resin.

  According to the present invention, a plurality of artificial teeth to be attached to an implant can be handled together, which is highly convenient. Moreover, since it processes with a resin material using CAD / CAM, it is possible to use it without choosing a case with dentures or an implant prosthesis.

1 is a perspective view of a connected artificial tooth row 10. It is the figure which looked at the connection artificial tooth row | line 10 from the occlusal surface 11a side. It is the figure which looked at the connection artificial tooth row | line 10 from the side in which the hole 12 was provided.

  The present invention will be described below based on embodiments shown in the drawings. However, the present invention is not limited to these forms.

  1 is a perspective view of a connected artificial tooth row 10 according to one embodiment, FIG. 2 is a plan view of the connected artificial tooth row 10 viewed from the occlusal surface side, and FIG. 3 is a view of the connected artificial tooth row 10 viewed from the hole 12 side. Each back view is shown.

  As can be seen from FIGS. 1 to 3, the connected artificial tooth row 10 is formed integrally by connecting a plurality of artificial teeth 11. Each artificial tooth 11 has an occlusal surface 11a, which simulates the occlusal surface of a natural tooth and has irregularities so as to function in the same manner as the occlusal surface of a natural tooth. On the other hand, the surface opposite to the occlusal surface 11a is provided with an abutment that is a connecting member to an artificial tooth root (implant) and a hole 12 that connects to a cylinder.

  The holes 12 are preferably provided in all the artificial teeth 11. Thereby, it can respond flexibly with respect to the position where the artificial tooth root is arrange | positioned. However, the present invention is not limited to this, and it is sufficient that at least one artificial tooth 11 has a hole 12 as long as the connected artificial tooth row 10 can be appropriately held in the oral cavity. Accordingly, holes 12 are formed in one or a plurality of artificial teeth 11 as necessary.

  Here, the connected artificial tooth row 10 is composed of artificial teeth 11 and does not have a part simulating gingiva. Therefore, the production is also easy.

  According to such a connected artificial tooth row 10, the artificial teeth 11 can be attached collectively to the artificial tooth root, so that convenience can be enhanced.

  Although it does not specifically limit as a resin material which comprises the connection artificial tooth row | line | column 10, Polymethyl methacrylate resin (PMMA) etc. can be mentioned. By using PMMA, stability in the oral cavity can be enhanced.

  The number of artificial teeth 11 included in the connected artificial tooth row 10 may be two or more, and the number is not limited. It may include all teeth as in the above form, or a part thereof.

  Such a connected artificial tooth row 10 can be manufactured as follows, for example. Hereinafter, an example using CAD / CAM will be described as one example of a method for producing the connected artificial tooth row 10.

First, in order to obtain the present form in the oral cavity of the patient, the occlusal surface form of the denture used at that time is measured with a three-dimensional measuring instrument or an intraoral measuring instrument, and the shape is taken into CAD as data.
From the obtained data, drawing is performed by CAD, and the portion lacking data is corrected and corrected on CAD.
The machine tool is controlled by using the CAM data on the tooth shape data thus obtained, and the connected artificial tooth row 10 is cut out from a plate-like material such as PMMA.
Thereby, the connection artificial tooth row | line 10 can be produced.

  The above-mentioned connected artificial tooth row 10 is mounted in the oral cavity and functions as a denture or an implant bridge. That is, an abutment or a cylinder is attached to an end portion on the inner side of the oral cavity of an artificial tooth root (implant) embedded in the jawbone in the oral cavity. Then, by inserting this abutment or cylinder into the hole 12 of the connected artificial tooth row 10, the connected artificial tooth row 10 is fixed in the oral cavity.
