We know that an optical scan of the patient’s master model provides the most accurate fit of the surgical guide. Elsewhere on this site a technique that employs a laboratory optical scanner is presented (ECO-DT Protocol ). However, that technique involves either extra trips by the patient or extra appliance fabrication by the clinician; at a cost to the patient. Intraoral scanners are becoming much more commonplace in clinical dental practice. But unlike the desktop scanner, an intraoral scanner cannot maintain the same coordinate system from scan to scan. We solve this problem by attaching a coordinate system to the patient’s model. This protocol is explained below, as well as in this article posted on LinkedIn: Scanbody for Hand-Held Scanning of a Denture for Surgical Guide Development.
