Abstract: Objective To compare the accuracy differences between magnetic sequential guides, mortise-and-tenon sequence guides, and dental implant robots in full-arch implantation, and to provide a reference for clinical application. Methods Thirty standardized mandibular full-arch models were selected and equally divided into three groups according to the implantation methods. Preoperative CBCT scans was taken for implant planning, and the three groups used the same plan for implant placement. Deviation analysis was performed based postoperative CBCT scanning. Results The dental implant robot group demonstrated the highest accuracy, followed by the magnetic sequential guide group, with the mortise-and-tenon sequential guide group showing the lowest accuracy. There was statistically significant differences among the three groups in terms of total deviation at the entry point, total deviation at the apex, and total angular deviation (P<0.05). There were also statistically significant differences in the horizontal and depth deviations at the entry point and at the apex (P<0.05). Conclusion Both the dental implant robot and magnetic sequential guide technology can achieve high precision in full-arch implantation. Clinicians can choose the appropriate method according to the specific situation.
