Abstract
An overdenture bar includes a U-shaped support beam configured to being coupled to a plurality of dental implants and extending generally above the mucus membrane of the gums. The U-shaped support beam has an anterior region and a pair of posterior extensions. At least one portion of the U-shaped support beam includes a plurality of retention elements extending generally normal to an outer surface of the U-shaped support beam in a plurality of directions. A method for producing a dental bar model on a CAD/CAM program to be fitted on a patient's upper or lower gingival surface includes the steps of selecting a longitudinal portion of the bar, adding protrusions to an upper portion of the bar and/or positioning a buccal finish line and a lingual finish between two boundary lines. The boundary lines illustrate the highest and lowest position of the finish lines.
