Key Points

This study aims to assess how different registration methods in dynamic computer-assisted implant surgery affect accuracy and efficiency.
Laboratory study evaluating three registration methods: ND, XC, XM.
Five operators placed 25 implants per group for a total of 75 implants in partially edentulous maxillary models.
Postoperative CBCT scans measured deviations at key implant points and statistical analysis utilized one-way ANOVA and Tukey's HSD test.
Mean 3D deviations at entry point were 1.06 mm (ND), 0.71 mm (XC), and 0.90 mm (XM).
At the apex, deviations were: 1.23 mm (ND), 0.83 mm (XC), and 1.07 mm (XM).
Angular deviation was highest in the ND group (2.96°), with significant difference at p = 0.028 when compared to XM.
