IntroductionThis technical innovation presents a method that reproduces the position of a dental implant after insertion without the reuse of X-ray radiation. %26lt;br%26gt;Material and MethodsAn implant was inserted into the natural gap between the canines and premolars of three domestic pigs. A Straumann Scanbody was then screwed to the implant, and a digital impression of the jaw segment was made. The scanbody was scanned using a hand-held scanner. This was followed by the radiological detection of implant position on a CBCT. On the computer, the position of the implant was calculated and compared with the radiologically detected position. %26lt;br%26gt;ResultsThe calculated and determined position of the dental implant by the scanner is in good agreement with the radiologically controlled position. %26lt;br%26gt;DiscussionEvaluating the position of implants using intraoral scans is an easy and radiation-free method of three-dimensional site assessment after superimposition over a three-dimensional data set.
