Clinical Factors Influence the Trueness of Intra-oral Scanning

Aims: The aim of this in vitro study was to evaluate the influence of adjacent teeth in the
trueness of digital impressions. Materials and Methods. In this study the first premolar on
a typodont mounted in a phantom head was prepared for an all ceramic crown. Three different operators scanned the tooth with an intraoral scanner, with three different clinical
scenarios: with no adjacent teeth, with one adjacent tooth and with two adjacent teeth.
Resulting scans from each operator were compared with a reference scan using metrology
software. Results: The results of this in vitro study showed differences of scanning trueness
between each clinical simulated situation. Conclusions: The presence of adjacent teeth can
decrease the view of interproximal surfaces and may generate a less precise scan in these
regions. The results of this study showed that the trueness of an intraoral digital impression
is conditioned by a good visibility of the abutment.
