（産業上の利用分野）
本発明は歯科医療に適用するブレード型骨内イ

した抜孔をあけ、該抜孔中に骨の増生浸入を図る
ようにしたものがあつた。(Prior Art) Conventionally used intraosseous implants made of, for example, titanium, vitalium, stainless steel, etc. are generally widely used because of their high mechanical strength. However, when implanted in the jawbone, adhesive bonding with the bone is difficult, and therefore it has been impossible to implant the implant with great mechanical strength. Therefore, in order to embed the implant in the bone with greater mechanical strength, the surface of the part where the implant is inserted into the bone has a satin finish (rough surface), a thin groove is formed, or an extraction hole is made that communicates on both sides. There was one in which a hole was drilled to allow bone growth to infiltrate into the hole.
（本発明が解決しようとする問題点）
ところが、骨内インプラントは顎骨を掘削した

できないという欠点があつた。(Problems to be Solved by the Present Invention) However, although intraosseous implants are inserted into recesses excavated in the jawbone, the jawbone is generally
Due to the relatively narrow width of about 12 to 18 mm, thick intraosseous implants cannot be used, and in particular, the thickness of the intraosseous implant part is thin, about 1.5 to 2.0 mm at most. Therefore, even if a deeper groove is formed on the side surface of the implanted part in order to increase the engagement effect with the bone, forming a deep groove will reduce the strength of the implant itself, and if the groove is shallow, the bone The disadvantage was that a large engagement effect could not be expected.
その結果、従来のインプラントは骨増生後にお

恐れがあつた。 As a result, conventional implants have little biting (engagement) even after bone augmentation, in other words, the mechanical engagement force is insufficient, and they tend to settle into the bone, causing phenomena such as looseness and dislodgement. I was afraid.

In addition, when providing the grooves on both sides of the implanted part, there is a limit to the thickness of the implanted part. , in order to form deeper grooves, the grooves provided on one side surface and the other side surface are offset from each other.
（実施例）
次に本発明に係るブレード型骨内インプラント
（以下、単にインプラントと略称する）の実施例
を図によつて具体的に説明する。(Example) Next, an example of a blade-type intraosseous implant (hereinafter simply referred to as an implant) according to the present invention will be specifically described with reference to the drawings.

A usage diagram is shown in which an intraosseous implantation part 2 is implanted and an artificial tooth crown T is attached to a post part 2 protruding from the gum S. Implant 1 used in this way
As shown in FIG. 2, in the longitudinal direction of the intraosseous implantation part 3, it is deeper and wider in the rows at the end,
Directly below and in the vicinity of the post portion 2, a plurality of tapered grooves 4 are formed which gradually become shallower and narrower in width. Such grooves 4 may not be provided symmetrically, but may be formed alternately as shown in FIG. 3.
ところで、インプラント１には片側面だけでは

ａ，４ｂであつてもよい。 By the way, the implant 1 has asymmetrical grooves 4, 4 not only on one side but also on both sides of the intraosseous implantation part 3, as shown in FIG.
It may be a or 4b.
また、第３図におけるＹ−Ｙ線断面を第６図に

陥孔に挿入し易いものとすることができる。 In addition, as shown in FIG. 6, which is a cross section taken along the Y-Y line in FIG. By keeping the wall thickness thin, it can be easily inserted into a recess drilled in the jawbone.
さらに、第４図に示した如く、骨内埋入部３の

しておくことが好ましい。 By the way, titanium, titanium alloy, vitalium, stainless steel, etc. are suitable materials for the implant 1, and in order to make it more biocompatible, an oxide film or the like is applied to the surface to an appropriate thickness. It is preferable.
なお、インプラント１の最大肉厚は1.3〜1.9mm

であつた。 The maximum wall thickness of implant 1 is 1.3 to 1.9 mm.
The degree was the one that most closely matched the average jawbone thickness of Japanese people. Therefore, in this case, the depth of the groove formed on the side surface was superior in terms of strength if it was formed at a ratio of about 2 to 3 or less in depth.

By forming grooves that gradually become deeper with a width of It is possible to provide an implant that has a large mechanical bonding force, can prevent dislodgement, rattling, and settling into the bone, and can provide stable occlusal properties over a long period of time.
