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.

The 1996 Denturist Association of Ontario fee guide and the Ontario Dental Association Fee Guide for General Practitioners were examined to identify variations in the fees charged for a range of removable prosthodontic services. Fee guides were selected for this analysis as third-party insurers and government dental plans frequently use them to establish fee schedules and levels of reimbursement. However, it is recognized that dentists set their own fees, which may be higher or lower than the fees suggested in the guide. Although the descriptions of the specific services listed in the guides were similar in many cases, no attempt was made to examine variations in the quality of care provided by dentists and denturists, or the approach to treatment offered by their respective professions. The analysis revealed that a number of procedure fees were, on average, 15 per cent higher in the Ontario Dental Association (ODA) fee guide compared to the denturists' fee guide. However, a wide range of prosthetic services, including partial dentures, were less expensive in the ODA fee guide. Based on this analysis, there appears to be no substantial cost differential between the services provided by dentists and denturists six years after the proclamation of the new Regulated Health Professions Act in Ontario, as the denturists have claimed. The denturist association's further claims of greater choice and improved access may also be questionable, and should be reexamined in light of these findings.
