Fixed removable prosthesis employing Marburg double crown system

The ultimate objective of the fabrication of a partial prosthetic appliance is the preservation of the remaining teeth while lost function is being restored. Double crown is an effective type of retainer that provides retention, support and a splinting action between multiple abutment teeth. Double crowns with clearance fit are used to retain tooth-mucosa and implant-supported removable partial dentures (RPDs). Retention is achieved by either functional molded borders or additional attachment. The double crown system retains dentures more effectively than do conventional clasp-retained RPDs, and also shows more favorable transmission of occlusal loading to the long axis of the abutment teeth. This case report will highlight the use of Marburg double crown system in the treatment of partially edentulous patients.
