本発明は有床義歯用の咬頭の形成方法並びにそ
れに用いる人工咬頭に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for forming a cusp for a denture, and an artificial cusp used therein.
（従来の技術）
例えば総義歯の場合には、咬頭にメタルブレー

臼歯の機能を高めたものが知られている。しかし
従来の金属性咬頭は、総義歯を製造する過程で取
付けるのに適した形状並びに構造を有するので、
部分的な補修に適さない問題があつた。(Prior Art) For example, in the case of complete dentures, it is known that the function of resin molars is enhanced by implanting metal cusps commonly called metal blades on the cusps. However, conventional metal cusps have a shape and structure suitable for attachment during the manufacturing process of complete dentures, so
There was a problem that made it unsuitable for partial repair.
そのため、一部に不具合がある場合でも、咬合
調整が容易でなく、全体を造り直さなければなら

ブレードを持つており、咀しやく性は良いが誤つ
て噛んだ場合など相手に与える影響も大きい。 Therefore, even if there is a defect in one part, it is not easy to adjust the occlusion and the entire part must be rebuilt. Additionally, the cusps used in the past have sharply pointed blades, which make them easier to chew, but they also have a greater impact on the other person if they are accidentally bitten.
（発明が解決しようとする課題）
本発明は前記の点を解決するもので、その課題

嵌合可能にするという手段を講じたものである。(Means for Solving the Problems) In order to solve the above problems, the present invention forms a recess in the cusp of a mandibular or maxillary denture using a drill having a predetermined blade shape, and forms an upper part of the artificial cusp that fits into the recess. Temporarily adhere the structure to the recess, press the end surface of the shaft of the lower structure of the artificial cusp onto the cusp of the upper or lower denture that occlusions with the denture, and make a mark; A recessed portion of a size that allows a lower structure to be implanted in the cusp of the denture is formed, and the lower structure of the artificial cusp is fixed to the recessed portion, so that the upper structure of the artificial cusp and the recessed portion can be fitted in a complementary manner. This is the measure taken.
