Objectives:
This study investigated the accuracy of robotic computer-assisted implant surgery (r-CAIS) for immediate implant placement.
Methods:
Twenty cases with 20 implant sites were selected based on predefined inclusion criteria. The preparation of the implant bed and implant placement followed the standardized dental implant robotic surgery protocol. Postoperative cone-beam computed tomography scans were conducted to assess possible discrepancies between actual and planned implant positions.
Results:
The r-CAIS technology for immediate implant placement exhibited a mean global coronal deviation of 0.71 ± 0.27 mm (95% CI: 0.58-0.83 mm), a mean global apical deviation of 0.69 ± 0.26 mm (95% CI: 0.56-0.81 mm), and an angular deviation of 1.27 ± 0.47° (95% CI: 1.05-1.49°). A substantial number of deviations were observed buccally at both coronal (90%) and apical (95%) levels, with a consistent tendency for buccal deviation.
Conclusions:
The r-CAIS technology proved a promising approach for immediate implantation in the anterior region, with satisfactory clinical outcomes. However, an optimized surgical protocol for r-CAIS technology is required for particular implant sites like extraction sockets or bone defects.
