抄録

The purpose of this study was to investigate the condition of a magnetic attachment, Hicorex MD, inserted in the oral cavity. The materials used were investigation cards regarding 1719 teeth for 1123 cases, offered from 261 dental offices in Japan where the Hicorex MD was used from Nov. 1992 to Mar. 1994. The results were as follows:
1. As for sex, there were 459 males (695 teeth), and 616 females (945 teeth), and 48 unknown cases (79teeth).
2. As for the site of maxillary tooth, the most common was the canine, the second was the 1 st premolar, the third was the 2 nd premolar, and the fourth was the central incisor. As for the mandible, the most common was the canine, the second was the 1 st premolar, the third was the 2 nd premolar, and the fourth was the lateral incisor.
3. As for the side effects, 5 out of 1, 123 cases were reported. The substances were color change of the keeper, swelling, and erosion of the gingiva. Only these 5 cases had all of the side effects. These could have been caused by the abutment teeth themselves not the magnetic attachment.
