Dynamic\u2010CAIS systems enhance surgical precision through real\u2010time feedback, though comparative data on their accuracy and efficiency remain limited. This study evaluated how different registration methods in d\u2010CAIS systems influence implant placement accuracy and procedural time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>In this laboratory study, three registration methods were assessed: ND group, XC group, and XM group. Five experienced operators placed 25 implants per group (75 total) in partially edentulous maxillary models. Postoperative CBCT scans were used to measure deviations at the implant entry point, apex, vertical depth, and angle. One\u2010way ANOVA and Tukey's HSD test were used for statistical analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Mean 3D deviations at the implant entry point were 1.06\u2009mm (ND), 0.71\u2009mm (XC), and 0.90\u2009mm (XM); at the apex 1.23\u2009mm, 0.83\u2009mm, and 1.07\u2009mm, respectively. Vertical depth deviations at the apex were similar across groups: 0.61\u2009mm (ND), 0.59\u2009mm (XC), and 0.64\u2009mm (XM). Angular deviation was highest in the ND group (2.96\u00b0) compared to XC (1.17\u00b0) and XM (1.02\u00b0), with a significant difference between ND and XM (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.028).
