The invention relates to a computer-aided process of dental bar design for the purpose of fabricating removable implant-based dental restorations. The aim of the invention is to improve and automate the present dental restoration design process, which is very labor intensive and requires a lot of artistic work on the part of a dentist. The invention includes the developments of several algorithms and their integration into a computer-aided system to process the gingival and related data scanned from a patient's mouth and output a CAD model for fabricating the actual dental bar. Software has been developed to implement the inventive process.
