title: Occlusal migration of a filled root: report of case.
abstract: A mandibular premolar was treated by root canal therapy. The root migrated 11 mm in an occlusal direction beneath the anterior retainer of a fixed partial denture during eight years after treatment. Caries occurred at the junction of the root and the anterior retainer; and, as caries continued, the root apparently migrated to compensate for the lost tooth structure.
