Abstract:

Objective:The aim of this study is to retrospect the retention and stability for fixed-removable denture with magnetic attach- ments.Methods: Magfit EX 600W magnetic attachments were used as the extra-coronal retainer on abutments, and the guide plane and Key-key way were applied as the stable structure for dentures. The fixed-removable dentures were fabricated in casting framework way. The applied effect of the fixed-removable denture was followed up.Results: The extensive defects of dentition of 15 cases were restored successfully with the fixed-removable dentures. The follow-up investigation showed that the compact, aes- thetic and comfortable fixed-removable denture could supply reliable retention, stability and highly masticatory efficiency.Conclu- sion: Magnetic attachments can be used in fixed-removable dentures and help to obtain reliable retention and stability of dentures.
