1. A method for designing and fabricating a dental prosthetic restoration based upon the position and orientation of a dental implant previously placed in a patient, without requiring a physical impression of the patient'"'"'s oral cavity, the method comprising the steps of:

  • a) installing a digital impression coping which properly engages said dental implant;

    b) scanning an image of the patient'"'"'s dental anatomy including at least said digital impression coping using an intra-oral imaging method;

    c) transmitting said scanned image to a fabricator of restorative dental prosthetics;

    d) using said scanned image to derive a corresponding prosthetic restoration and its relevant position and orientation characteristics for the patient and installed implant including the step of correlating said scanned image to a library of digital impression coping data to derive angular and vertical position data and locking orientation information of said installed implant; and

    e) generating said corresponding prosthetic restoration for installation in said patient.
