Fabrication of a Fractured Mandibular Bar-Retained Implant Overdenture Without Implant-Level Impression Making: A Clinical Report

摘要

The most frequent mechanical complications of bar-retained implant overdentures (IODs) are fracture of the dentures, loosening of the bar screws, and the need to reactivate the retentive clips. When a bar-retained IOD with an acrylic resin base fractures, the existing bar attachment should be removed to fabricate a new overdenture. So far, no method has been previously described for remaking a fractured mandibular bar-retained IOD without removing the existing bar attachment. This article describes fabrication of a fractured mandibular bar-retained IOD with distally placed ball attachments using attachment transfer analogs. The described technique allows the patient to use the existing overdenture temporarily until the new overdenture is delivered.
