Eleven implants were placed using the novel dCAIS system that determines patient positioning based on anterior tooth anatomy (Prototype group), while 22 implants were placed using a conventional dCAIS system requiring standard registration and an optical tracking marker (Control group). Pre\u2010 and postoperative cone\u2010beam computed tomography (CBCT) scans were superimposed to assess implant placement accuracy. Descriptive and bivariate analyses were performed to compare accuracy and surgery time between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Mean angular deviations were similar between groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.924): 1.95\u00b0 (SD 1.38) in the prototype group and 2.38\u00b0 (SD 2.30) in the control group.
