By using intra-oral optical scanning devices, the need for patients to have a messy conventional dental impression taken of their teeth is eliminated. Digital optical impressions enable the dentist to more efficiently and effectively obtain an accurate computer generated representation of their patient’s teeth along with the surrounding tissues. In addition to being much more comfortable for the patient, a digital impression eliminates the need for the dentist to either create a stone model from the impression, or to mail the impression directly to the laboratory for any type of work to be done. Digital impression information is transmitted electronically, significantly reducing the turnaround time of any needed outside laboratory work. Digital impressions are also integral to systems that produce same day, in-office ceramic restorations.
