Description

      The present invention relates to a training instrument for training and training of implant planting procedures, and more particularly to a training instrument for implant planting that communicates between the living body and the living body, such as a dental implant.

  As a training instrument for implant treatment, jaw bone models as shown in JP-A-10-33574 and JP-A-2001-120578 are shown, but the handling is complicated and the price of the model itself is high. It is expensive, not suitable for repeated training, and it cannot be said that sufficient training is possible. On the other hand, a wooden triangular prism as disclosed in Utility Model Registration No. 312424 can be provided at a lower cost, but this is a configuration for screwing a screw into the jawbone slope for orthodontic treatment training. It remains, and its application to implants remains unclear.

  A series of training tools for implant surgery has a complicated shape that more mimics living tissue, and it is difficult to say that it can be used easily. However, there is still no easy-to-use training tool for general treatment.

  In view of the above, the present invention is a solid having one or more curved surfaces of a site to be implanted, and a structure in which a pseudo soft tissue is formed on the surface can take a configuration in which a series of implant operation can be practiced. The present invention has been found and reached.

The present invention can be configured so that it is possible to train a series of procedures of an implant while having a simpler configuration.

The material of the core material in the present invention is, for example, a resin such as dense ceramic or porous material such as feldspar, alumina, zirconia, apatite, rubber, PET (polyethylene terephthalate), PP (polypropylene), polyvinyl chloride, polyester, polyurethane, etc. Alternatively, a porous body, paper block, wood, plaster, or the like made of these resins is shown, and one of them may be selected, or a plurality of members may be combined.
In practice, the core material is preferably a material that can provide a feel similar to that when drilling into the alveolar bone, such as an artificial bone material.
The shape is at least a member having a curved surface to be implanted, a truncated cone having a vertex, a triangular prism, a triangular pyramid, a hexagonal prism, a pentagonal prism, and the like having a plurality of angles to be implanted. Are illustrated.

The curved surface preferably has a shape having respective vertices in one core material, imitating the curved surface of the alveolar bone near the back teeth and anterior teeth.
The double-sided adhesive tape-like intermediate layer that bonds the surface of the core material and the pseudogingiva may be, for example, a non-woven fabric, a paper-coated double-sided adhesive, or a commercially available double-sided tape.
In some cases, the adhesive intermediate layer may be formed of only an adhesive.
Examples of the pseudogingival material that becomes the gingival tissue as the outermost layer include synthetic resins such as urethane, natural rubber, and synthetic rubber. However, if the same feel as in the case of actually cutting and suturing the gingiva is obtained, it is limited to these. is not.
In any case, if the material is a three-dimensional shape with a curved surface to be implanted, and a layer of pseudo-gingiva, the material is appropriately selected on the condition that a feeling of actual drilling, peeling, and suturing operations can be obtained. May be.

  The present invention may be a solid having a vertex having a curved surface to be a dental implant planting object, but stable placement, multiple use, parts having different curved surfaces corresponding to the front tooth part and the back tooth part A triangular prism shape is preferable in that it can be used for implant planting training. Usually, a pseudo gingival sheet is bonded to a triangular pillar core material using a double-sided tape.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a view showing an embodiment of the present invention, FIG. 1 (a) is a front view, and FIG. 1 (b) is a perspective view.
(11) is a core material, which is a triangular prism-like body formed of a polyurethane porous material.
Each vertex of the core material (11) is provided with a curved surface that approximately matches the curved surfaces (a1) to (a3) of the alveolar bone near the back teeth, the front teeth, and the tooth measurement.
(12) is an adhesive intermediate layer, which is formed by applying an adhesive to both surfaces of a nonwoven fabric. The adhesive intermediate layer (12) may be an adhesive alone or a double-sided adhesive tape.
(13) is a pseudogingival layer and is formed of natural rubber. The thickness is about 2 mm to 4 mm, but may be other thickness depending on the purpose of training.
The practice instrument (01) shown in the present embodiment is formed by arranging curved surfaces with different curvatures at the vertices of an equilateral triangle. The overall size is approximately 60 mm on one side of the equilateral triangle and the height is about 60 mm. About 50 mm.
The curvature associated with the curved surface of each vertex may be at least a curvature corresponding to the diameter of the implant intended to be planted. For example, the curved surface (a1) is a curvature that allows an implant with a diameter of 5φ, and the curved surface (a2) The curvature of the curved surface (a3) is preferably adjusted for an implant having a diameter of 3φ, and the curved surface (a3) may be provided with a vertex whose curvature is adjusted according to the diameter of the implant.

Next, an example of use of the present invention during training will be described in detail with reference to FIG.
As shown in FIG. 2A, the practice instrument (01) is placed with the apex having the curvature of the part to be trained facing up.
The pseudogingival layer (13) is incised using a cutting tool such as a scalpel that is actually used. An example of the incision is shown in (21). There may be a plurality of incisions. FIG. 2A is just an example.
Next, FIGS. 2B to 2E show cross sections taken along line xx ′ of FIG. As shown in FIG. 2B, the pseudogingival layer (13) and the adhesive intermediate layer (12) are peeled off. Furthermore, actually, using the jig R for perforating the alveolar bone, the core material (11) is perforated to form a cylindrical perforated portion (22) (FIG. 2 (c)).
The artificial tooth root (I) is inserted into the perforated part (22) (FIG. 2 (d)), the adhesive intermediate layer (12) and the pseudogingival layer (13) are returned to the original state (FIG. 2 (e)). The suture is sutured with the surgical thread used (FIG. 2 (f)). The stitched portion is shown in (23), but this is merely an example, and is appropriately selected depending on the training mode and method.

Another embodiment is shown in FIG. FIG. 3 is suitable for use as a training device (02) of the socket lift method when implanting an implant with a gap in the alveolar bone.
Except for the cavity (14) and the cavity membrane (15) formed on the surface thereof, the shape is the same as in FIG.
The cavity (14) is preferably formed at a distance (L) of approximately 3 to 5 mm, preferably 3 to 4 mm, from the apex having a curved surface, but it varies depending on the patient's condition. And may be used for practice.
The cavity membrane (15) has a thickness of 0.01 mm to 0.1 mm, preferably 0.015 to 0.04, and is formed of a silicone material having a property of being easily broken near the actual thickness. Suitable for practice.
The cavity (14) corresponds to, for example, the maxillary sinus, and the size thereof is often larger than that of the practice instrument (02). A cylindrical cavity of 5 mm to 10 mm is exemplified.

Next, a usage example of the embodiment shown in FIG. 3 is shown in FIG. FIG. 4 shows a cross-sectional state similar to the xx ′ cross-section of FIG.
FIG. 4 (a) shows a state similar to the state in which the perforated part (41) is to be formed in the alveolar bone with the jig R. However, the device can be used for training the operation.
FIG. 4B shows a state in which the artificial tooth root (I) is planted. The prosthetic coagulation material (42) (using silicone cured resin etc.) is injected by the socket lift method to solidify and resemble the bone, drilled again, and artificial root (I) is embedded there . In some cases, a coagulant is not injected.
Since the cavity (14) penetrates the core (11), the state of the film can be observed by observing the cavity (14). The present invention can also be used for training difficult procedures such as the socket lift method.

  Since the present invention can be effectively used at low cost as a practice instrument / training instrument for learning a dental implant planting technique, the present invention is suitably used for private medical practitioners, students, residents, and the like.
