The typodonts were scanned without scanning aids [TRI_WSA and EMR_WSA groups] (\n                      <jats:italic>n<\/jats:italic>\n                      = 10).

Conventional impressions of both arches were also made using irreversible hydrocolloids in stock trays [IHC] and using polyvinyl siloxane (PVS) impression material in custom trays (\n                      <jats:italic>n<\/jats:italic>\n                      = 10) which were digitized using a laboratory scanner. Using a metrology software program, all scans were compared to a reference scan in order to assess trueness and to each other to assess precision. Trueness and precision were expressed as the root mean square (RMS) of the absolute deviation values and the statistical analysis was modeled on a logarithmic scale using fixed\u2010effects models to meet model assumptions (\n                      <jats:italic>\u03b1<\/jats:italic>\n                      = 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The main effect of arch (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.004), scanner (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001), scanning aid (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.041), and the interaction between scanner and scanning aid (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.027) had a significant effect on mean RMS values of trueness. The arch (\n                      <jats:italic>p<\/jats:italic>\n                      = 0.015) and scanner (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001) had a significant effect on the mean RMS values of precision. The maxillary arch had better accuracy compared to the mandible. The TRIOS 4 scanner had better accuracy than both the Emerald S scanner and conventional impressions. The Emerald S had better precision than conventional impressions. The scanning spray and liquid\u2010type scanning aids produced the best trueness with the TRIOS 4 scanner, while the liquid\u2010type scanning aid and composite markers produced the best trueness for the Emerald S scanner.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The scanned arch and the type of scanner had a significant effect on the accuracy of digital scans of completely edentulous arches.
