Abstract: 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.

Abstract: An impact platform device for use with a virtual reality interface system that promotes navigation by a user in a virtual environment, the platform device including a platform being configured to receive impacts from the user, an odd-numbered plurality of sensors evenly spaced about a circumference and disposed relative the platform such that each of the sensors is configured to detect when the user impacts a portion of the platform.
