ABSTRACT Objectives Materials and Methods Results Conclusions To evaluate and compare the accuracy of task‐autonomous robot‐assisted implant surgery (RAIS) and dynamic computer‐assisted implant surgery (dCAIS) for zygomatic implant placement.Ten atrophic edentulous maxilla models requiring zygomatic implant (ZI) placement were randomly divided into the RAIS and dCAIS groups. Osteotomies and implant placement were performed under the guidance of a task‐autonomous robotic system or dynamic navigation system. A total of 20 ZIs were analyzed. The angular, coronal, lateral coronal, coronal depth, apical, lateral apical, and apical depth deviations were measured and analyzed between the two groups. The primary outcome parameters were the angular deviations between the planned and the placed ZIs. Data was subjected to descriptive and comparative statistical analysis. The significance of inter‐group differences for continuous variables was assessed with Student's two‐sample t‐tests, Welch two‐sample t‐tests, and Mann–Whitney U tests according to the distribution normality and variance homogeneity.ZI placement deviations were compared between the RAIS and dCAIS groups, showing a mean angular deviation of 0.92 ± 0.40° versus 2.03 ± 0.53° (p < 0.001), a mean (±SD) coronal deviation of 0.48 ± 0.25 mm versus 1.29 ± 0.46 mm (p < 0.001), and a mean apical deviation of 0.88 ± 0.28 mm versus 1.96 ± 0.46 mm (p < 0.001).For computer‐guided ZI placement, task‐autonomous RAIS was superior to dCAIS in terms of accuracy.
