The present chapter deals with the introduction and implementation of rapid prototyping technologies in medical and dental field. Its purpose is to overview the advantages and limitations derived, to discuss the current status and to present the future directions, especially in dental sector. Furthermore, a flowchart is outlined describing the procedure from the patient to the final 3-D object, presenting the possible alternatives in the process. Finally, an example is presented, decribing the process of the construction of high accurate surgical guided templates in dental implantology, through rapid prototyping.
