1. A method for producing a dental prosthesis for a patient, comprising the steps of:

  • measuring a tooth of the patient, the measuring step comprising moving a probe in proximity to the tooth, wherein the probe provides light to the surface of the tooth from one or more light sources, and receives light reflected from the tooth through a plurality of light receivers, determining the intensity of reflected light received by more than one of the light receivers with first sensors, and measuring the optical characteristics of the tooth with second sensors based on light received by one or more of the light receivers in response to the intensity determinations made by the first sensors wherein the measurement produces data indicative of the optical characteristics of the tooth;

    generating data for the dental prosthesis based on the measured data; and

    preparing the dental prosthesis based on the generated data.
