Repairing and strengthening a fractured Hader bar
The Journal of Prosthetic Dentistry
|January 1, 1997
Abstract:
Stresses from occlusion and metal fatigue over time can cause fracture of overdenture retention bars. Often failure of the bar necessitates the removal and remake of the bar. This may damage the abutment, especially if there are dowel posts involved. This article describes a method for reinforcing the existing bar without having to remove the bar or significantly alter the overdenture. The fractured bar can be prepared in the mouth to receive a reinforcing superstructure that will be cemented.
