BALL-TYPE ATTACHMENT DEVICE FOR OVERDENTURES, AND METHOD OF PRODUCING OVERDENTURES TO WHICH BALL-TYPE ATTACHMENT IS APPLIED

摘要

Disclosed are a ball-type attachment device for overdentures, and a method of producing overdentures to which a ball-type attachment is applied. A ball-type attachment device for overdentures according to the present invention relates to an attachment device for implant-supporting overdentures, which includes an abutment having a ball-shaped coupling protrusion formed on the exposed end thereof, and a retainer separably coupled through snap-fitting to the coupling protrusion. The retainer comprises: a cushioning part formed of an elastically deformable material in which a coupling recess is formed in a shape corresponding to the ball shape of the coupling protrusion in order for the coupling protrusion to be inserted and coupled therein in a separable manner; and a fixing part fixed to the overdentures and having a receiving recess formed therein in which the cushioning part is received in order for the cushioning part to be inserted and coupled therein.
