  • Title: Fabrication of a fractured mandibular bar-retained implant overdenture without implant-level impression making: a clinical report.
    Author: Uludag B.
    Journal: J Prosthodont; 2012 Dec; 21(8):622-5. PubMed ID: 22938207.
    Abstract:
    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.
