Simplified procedure for replacement of retentive clips in a bar-retained implant overdenture.
Replacing the retentive elements in a bar-retained overdenture can be a difficult and time-consuming procedure. This article describes an impression procedure that allows the matrices in a bar-retained implant overdenture to be replaced in the laboratory using a heat-cured rebase procedure. Long waxing screws are used, which allows the bar to be removed in the rebase impression and incorporated in a new master cast. After completion of the laboratory phase, the bar is screwed back onto the implant abutments and the denture, with new retentive matrices, is inserted.
