Magnetic attachments are regarded as the third generation retainer, and they are used extensively for the implant prosthesis. However, damage of the denture and recovery of it should be taken into consideration for long-term usage. We have treated 20 cases with magnetic bar attachments in six years. Although there are very few cases of trouble, we report the causes, recovery, and consideration points. The main trouble is ill fitness of dentures. In direct rebase after tissue conditioning and pressure impression was done for recovery. It was suggested that rebase could be done securely and easily because the relations of the bars and dentures were stable.
