Overdenture bars secured to a portion of a jaw bone provide a mounting platform for dental prosthetics. One method to form an overdenture bar includes obtaining a digital image of a portion of a mouth, transferring the image to a computer and forming a three dimensional image of the portion. A virtual overdenture bar is designed to terminate at opposing first and second distal ends and have a first thickness defined by opposing first and second surfaces. The overdenture bar has an extension projecting from at least one distal end adjacent the second surface. Each extension has a second thickness that is less than the first thickness. A socket extends through each extension for engagement with the dental prosthetic. A digital file of the virtual overdenture bar is transferred to a number controlled machine and the overdenture bar and extensions machined from a single piece of stock material.
