Description of the Related Art Dental implants include two-part, one-time implants in which a portion to be implanted in hard tissue and a portion to which a denture is attached are extended to a state protruding above the gingiva. There are two-part, two-time implants where the part to be implanted in the tissue and the part to which the denture is worn are at a height that is hidden from the gingiva. The two-part, one-time implant implants the implant at a height up to the gingival surface and inserts the joint holes used to join the denture to the implant until foreign matter is inserted until the denture is attached. Temporary lid (Healing Cap or Healing Abutment) to cover to prevent
Is carried out while protruding above the gingiva. This form of implant has the advantage that only one surgery is required, and the physical and financial burden on the patient is less than with the double procedure.

(FIG. 3 (a)), the temporary lid (healing cap or healing abutment) 31 described above is attached, and the gingiva is completely closed (H) (FIG. 3 (b)). After a certain period of time, the gingiva is incised again (HK2), the temporary lid 31 is removed (FIG. 3 (c)), and the abutment B is mounted (FIG. 3 (d)).

It has advantages and disadvantages in that the upper structure such as a denture must be joined and a burden is imposed on the patient. It is very difficult to overcome such drawbacks, since the living body must be gently laid after the implant has been implanted until the implant is adapted.

It is also suitably used in composite materials that have been used. The temporary lid according to the present invention is connected to the plant body, and at the same time, keeps the joint state while allowing the plant body to stand still for adaptation to the living body for a certain period of time, and in the meantime, secures the site for mounting the upper structure during the period. Should be of a shape suitable for securing the upper structure, and furthermore, this temporary lid body, during its standing period, the influence of swinging due to mastication, etc. There may be a case where the protrusion is equal to or slightly larger than the gingival surface to such an extent that it is not received.

At this time, a shape having a spread from the three-dimensional solid to the upper portion of the temporary lid body is good, and a slope (taper) indicating the manner of spread (for example, FIG. 1)
85 ° to 55 ° (preferably 7)
0 degrees to 60 degrees). The thickness ((8) shown in FIG. 2) is preferably such that the temporary lid does not protrude from the gingival part to slightly protrude after the temporary lid is attached to the three-dimensional plant, and is, for example, 0.5 mm to 2.0 mm. However, since it differs depending on the patient, the part to be implanted, and the like, it is appropriately selected and is not limited thereto.

The temporary lid may have a structure in which the height is finely adjusted at the time of joining with the plant body. For example, the height of the temporary lid 2 is adjusted by adjusting the degree of accumulation of the screw portion 7 of the temporary lid 2 shown in FIG. In this case, a sealed body made of silicone rubber or the like or a sealed joint form may be preferably formed on the temporary lid side. In addition, when implanting a solid body in the jawbone,
It works better if the temporary lid is erected in advance in a state of being joined to the three-dimensional body. This is because it is possible to prevent the inside of the joint from being contaminated with tissue or blood when the temporary lid is attached after the implantation. This method is appropriately selected depending on the distance from the opposing tooth, the thickness of the gingiva, and the like.

The joining hole 5 has two stages of holes, and the deep portion has a screw structure for joining and fastening to the joining portion 7. The shallow part is a mortar-shaped structure having a mating effect function to enhance the sealing performance when fixing the upper structure, and a hexagonal shape, an octagonal shape, and a rotation preventing function when fixing the upper structure, In some cases, it is processed into a unique shape having a lock mechanism. In the case of a hexagonal shape or an octagonal shape, a portion of the temporary lid 2 that is in contact with the temporary lid 2 is processed with a circle inscribed in the hexagonal shape or the octagonal shape. The contact surface 6, as described above,
It is preferable that a member and a treatment that do not react with the living body are applied. On the upper surface of the temporary lid 2, a groove of a plus type, a minus type, a hexagonal type, or another screw upper structure is preferably formed. The contact surface 6 is provided with a molding 10 having the above-mentioned inclination. The groove is for facilitating the use of a jig when attaching and detaching the temporary lid 2 from the plant body 1. The groove may have other configurations depending on the jig and other attaching and detaching methods.

In particular, normal eating habits can be carried out without covering the planting site with a protective body. After standing, the temporary lid 2 is removed (FIG. 2D). In this state, for example, an impression of a denture shape or the like is acquired, and based on the impression, the denture portion B is joined to the hole 5 of the plant 3 using conventional technology (FIG. 2E). The result is shown in FIG. Since there is a sufficient space in the gingival part around the upper surface of the implant 3, the upper structure is connected to the gingiva, so that a denture whose appearance is almost the same as natural teeth can be formed.
