ABSTRACT:
The aim of the present invention is to offer a keeper for a dental magnetic attachment that is strong, has low manufacturing costs, and is not easily detached from the tooth root. The keeper proposed herein has a keeper body, which is shaped like a plate, and a root, which is attached to the bottom of the keeper body. The keeper body and the root are machined from a single piece of soft magnetic material in one piece. The root has a smaller diameter part that is linked to a larger diameter part whose external diameter is larger than an external diameter of the smaller diameter part. The smaller diameter part is linked to the bottom of the keeper. There are multiple circumferential grooves around the outer side of the larger diameter part.
