骨内インプラント用部材に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for an intraosseous implant having a male screw portion such as a sealing member for preventing a body fluid from entering an opening hole of the intraosseous implant and a member for fixing an upper structure to the intraosseous implant. It is a thing.

有する。2. Description of the Related Art At present, there are two types of intraosseous implants (hereinafter referred to as implants) in the dental field, which are a cylinder type and a blade type. Cylinder type implants with a cylindrical appearance shape are roughly classified into three types: cylindrical, conical, and screw (including taper screw).
There are types. Further, the blade type has a plate-like appearance.

歯肉を貫通して、口腔内に露出しており、上部構造体装
着時に歯肉を切開しなくてよい。Further, the implanting method includes an "double-dose method" and a "single-dose method". In the former, the implant is completely embedded in the bone at the time of implantation (primary operation), and after several months, the gingiva is incised and the superstructure is attached to the implant (secondary operation). On the other hand, in the latter case, the implant penetrates the gingiva at the time of implantation and is exposed in the oral cavity, so that the gingiva does not need to be incised when the superstructure is attached.

する必要が生じる。By the way, regardless of the one-time method or the two-time method, in implant treatment, in order to easily and surely fasten the upper structure to the implant, the implant body is provided with a female screw hole opened on the upper surface, Most of the existing products use the method of fastening the upper structure by screwing it. In addition, in order to prevent the invasion of body fluid into the female screw hole after implantation, it is necessary to seal the female screw hole with a sealing cap between the implantation and mounting of the upper structure.

ている。The female screw hole does not necessarily have to start from the entrance portion, and the entrance portion is usually chamfered so that a male screw can be easily inserted. Depending on the case, the entrance portion of the female screw hole may be formed into a cylindrical shape (non-screw portion) having an appropriate length as a guide hole for the male screw. As described above, in implant treatment, an operation of attaching or detaching the male screw in the oral cavity is absolutely necessary. There are various sizes of these male screws, but for those for endosseous implants used in the dental field,
The outer diameter of the male screw is 1.2 to 2.5 mm, and the total length is 3 to 20.
The outside diameter of the male screw is 2 mm.
A male screw having a length of 5 mm and a total length of 5 to 10 mm is often used.

ある。[Problems to be Solved by the Invention] Although a surgeon must attach or detach these male screws by fingers in a very narrow space in the human mouth, the operation is very difficult and There is a problem that the male screw may fall into the oral cavity of the patient and it is very difficult to take out the male screw.

Since the materials of these male screws are mostly titanium and titanium alloys, it is not possible to hold the male screws using magnetic force. The present invention does not fall into the oral cavity when it is attached or detached in the oral cavity,
Moreover, it is an object of the present invention to provide a member for an intraosseous implant having a male screw portion with excellent operability.

に至った。In a normal intraosseous implant member having a male threaded portion, there is almost no tip portion having an outer diameter or outer dimension smaller than that of the male threaded portion at the tip of the male threaded portion.
If present, the site is of very small length and serves only as a guide during insertion of the member into the intraosseous implant. As a result of diligent research, the inventors of the present invention have determined that the outer diameter or the outer dimension and the length of the portion are compared with the inner diameter or the inner dimension of the opened hole or the screw hole, and the outer diameter or the outer dimension of the male screw portion. Then, the inventors have found that the possibility of falling off during operation of the member for an intraosseous implant can be reduced or eliminated and the operability can be improved by adjusting, and the present invention has been completed.

る。When implanting the member for an intraosseous implant according to the present invention in a corresponding opening hole or screw hole, first,
With the tip portion serving as a guide, the axis of the female screw hole and the axis of the male screw portion are easily aligned with each other. Therefore, the subsequent screwing operation between the female screw hole and the male screw portion becomes easy. Further, in a state in which the distal end portion of the member for intraosseous implant is inserted into the opening hole or the screw hole of the intraosseous implant, even if the operator does not press the member, the member has a post hole (opening hole) or a screw hole.

問題がない。Therefore, until the male screw portion starts to be screwed into the female screw hole by rotating the member, the operator should always push the member in the female screw hole direction so that the member does not fall down. It becomes unnecessary and the male screw part can be screwed in very easily. Further, since the member does not drop at any time when the fingers are released, there is no problem even if an unexpected situation occurs during screwing.

る。When the size of the tip portion of the member for an intraosseous implant deviates from the conditions described in claims 1, 2 and 8 to 13, the member has an opening hole or screw hole of the intraosseous implant or an opening of a fastening member. When entering a hole or screw hole,
The upright state of the member becomes unstable, and the possibility that the member will fall into the oral cavity rapidly increases. The member for an intraosseous implant according to the present invention is, for example, a sealing cap (Claim 3 or 4), an upper structure (Claim 5 or 6), a fastening member (Claim 7, 10 or 11), or another fastening. It can be applied to a member (claims 8, 9, 12 or 13).

The sealing cap and the upper structure (healing upper structure) used to seal the opening hole of the implant are considerably difficult to screw. Therefore, in such a case, the sealing cap according to claim 3 or 4 or the upper structure according to claim 5 or 6 is effective.
