1. A method for fabricating a dental prosthesis for a patient, comprising: acquiring one or more high resolution digital scanned images of one or more oral structures of said patient using one or more digital image scanning devices; acquiring one or more three dimensional cone beam X-ray images of hard oral tissues and soft oral tissues of said patient using a cone beam X-ray image device; integrating said one or more high resolution digital scanned images of said one or more oral structures with said one or more three dimensional cone beam X-ray images of said hard oral tissues and said soft oral tissues of said patient in a three dimensional space to obtain one or more combined three dimensional images of said one or more oral structures of said patient; digitally simulating an occlusal relationship between upper oral structures and lower oral structures using said combined three dimensional images for digitally articulating said upper oral structures and said lower oral structures; digitally modeling said dental prosthesis based on said digitally articulated upper oral structures and lower oral structures to generate a digital dental prosthesis model for planning intra-oral positioning and structure of said dental prosthesis; refining said digital dental prosthesis model based on simulated force tests performed for assessing interference and retention of said digital dental prosthesis model; creating a prospective dental prosthesis model based on said refined digital dental prosthesis model, wherein said prospective dental prosthesis model is tested for verifying predetermined functions of said prospective dental prosthesis model; and fabricating said dental prosthesis based on said tested and verified prospective dental prosthesis model.
