Field of the Invention The present invention provides an abutment for a dental implant (hereinafter sometimes abbreviated as an abutment) in which a layer for cushioning external force and impact during occlusion and mastication is provided at a joint portion with a crown.
Regarding The dental implant abutment is an artificial support base for a dental crown that is combined with the dental crown.

と高度に結合して顎骨内に強く固定される。2. Description of the Related Art Conventionally, when tooth decay is extremely advanced,
After removing the root of a natural tooth, an artificial dental implant is implanted in the jawbone. In this case, as the material for the implant, "metal such as titanium or titanium alloy"
In addition, "a bioactive material such as hydroxyapatite (HAP) or tricalcium phosphate having a high bone affinity" and "a material obtained by coating the former with the latter" are used. Implants using these materials are highly bonded to the jaw bone tissue and strongly fixed in the jaw bone.

ている。Since the implant is fixed to the jawbone, the occlusal force and the chewing force are directly transmitted to the jawbone, and a chewing feeling different from that of natural teeth occurs. In extreme cases, the implant, the implant-jaw bone interface, or the jaw bone is destroyed. Furthermore, the jawbone around the implant is absorbed and disappears. On the other hand, in the case of natural teeth, there is a periodontal ligament connected to the jawbone around the root. The periodontal ligament plays a cushioning function that does not directly transmit external force or impact generated during occlusion and mastication to the jawbone.

いた。Therefore, it is necessary to provide somewhere in the implant with a cushioning mechanism corresponding to the periodontal ligament. conventionally,
A cushioning material 11,12 such as rubber may be inserted between the outer and inner crowns of the crown (Fig. 3 and JP-B-61-4261, JP-B-2-21).
H.264), and a method of providing an elastic body such as polyoxymethylene between the implant and the abutment (see Journal of The Society of Jaw and Occlusion 1989, Vol. 10, No. 1, pages 15-25). .

Due to the complexity of its structure, it required a difficult skill and a lot of time in terms of engineering. Moreover, food residues may enter the gap between the inner crown and the outer crown between which the cushioning material is sandwiched, and may not function sufficiently or bacteria may propagate.

という問題があった。In the case of "providing an elastic body such as polyoxymethylene between the implant and the abutment" in (1), since the space between the implant and the abutment is located below the edge of the gingiva, the implant is inserted through the elastic body. It is easy to pinch the gingiva when joining the and abutment. That is, since the elastic body is not sufficiently joined, the cushioning effect of the elastic body becomes insufficient. Further, there is a problem that the elastic body is easily deteriorated and must be replaced within 1 to 2 years.

(3) The mold was opened, and the abutment 1 on which the buffer layer 2 was formed was taken out from the mold. The Young's modulus of the buffer layer 2 is 40 to 10
It was 0 kgf / cm 2 . After joining the abutment 4 and the abutment 1 to the artificial tooth root 5 implanted in the jawbone 7 of the patient, zinc phosphate cement (not shown) is applied to the buffer layer 2 on the abutment 1 to apply the crown. When 3 was joined, the external force and impact generated by occlusion and chewing were alleviated by the buffer layer 2 and prevented from being directly transmitted to the artificial tooth root 5 and the like and the jawbone 7. Further, the buffer layer 2 exhibited the same function as the periodontal ligament of natural teeth, and a natural chewing sensation close to that of natural teeth was obtained.

Similar effects were obtained with the dental implant abutment 1 in which the buffer layer 2 was formed of a polyurethane layer or a polyoxymethylene layer. In the case of a polyurethane layer, hexamethylene glycol and tetramethylene diisocyanate, which are raw materials for polyurethane, were filled in the space in the mold and reacted and cured to form the buffer layer 2. In the case of a polyoxymethylene layer, the buffer layer 2 was formed by injecting and molding a molten polyoxymethylene raw material into the space of the mold.

It was possible to recover the occlusal function and prolong the life of the natural teeth without being transmitted to the natural teeth.
