CAD/CAM work flow

Female patient, healthy, 48 years old, attended the clinic unhappy with the aesthetics of her smile due to the presence of a maladaptation metal-ceramic crown associated with the tooth 33. It was previously endodontic and had no symptoms. According to the American Association of Endodontists the endodontic diagnosis is pretreated tooth and normal periapical tissues. The periodontal disease of the patient was stable, being in the periodontal support treatment at about one year. Through the CAD/CAM technology, the crown was replaced in a single appointment. CAD/CAM technology is not recent, as the first indirect restoration was made in 1983 by François Duret. However the medical-dental community has recently witnessed an exponential evolution of techniques and materials used in this field. This great scientific evolution allows a harmonious and fast workflow, in which the dentist can keep control of all phases of work. It also represents a great advantage for the patient since he can see his rehabilitation completed in a single appointment, avoiding consecutive visits and obtaining a final result equal to the conventional methods.
