A recent study comparing robotic-assisted and freehand dental implant placement has revealed significant differences in accuracy. While robotic surgery demonstrated superior precision in implant positioning, it required slightly more time per procedure. Despite the variance in accuracy, both methods had a 100% implant survival rate after six months, showing promising results for both techniques.

The integration of robotics in dentistry is no longer a futuristic concept but a reality that is beginning to reshape implantology. A recent clinical study evaluated the accuracy, efficiency, and safety of robotic-assisted implant placement compared to the traditional freehand method. The study involved 24 patients requiring single-tooth implants, randomly assigned to either robotic-assisted or freehand placement.

The results showed that robotic-assisted implants had significantly lower deviations in positioning compared to freehand surgery.

The global platform and apex deviations in the robotic group were just 0.70 mm on average, compared to 1.24 mm and 2.13 mm, respectively, in the freehand group.

The angular deviation was also notably lower in robotic-assisted surgery at just 1.09°, while freehand placements had a deviation of 7.43°. These figures highlight the enhanced precision robotic assistance offers, which could lead to improved long-term outcomes and prosthetic stability.

However, precision came at a slight cost in terms of time. The robotic-assisted procedures took an average of 18.8 minutes, slightly longer than freehand techniques, due to the additional steps required for registration and setup. Despite this, both techniques demonstrated excellent safety profiles, with no significant differences in intraoperative or postoperative complications. At the six-month follow-up, the implant survival rate was 100% for both groups, reinforcing the reliability of both approaches.

While robotic implant placement is not yet a standard practice in most dental clinics, this study suggests that its superior accuracy could make it a valuable tool in complex or high-precision cases. The challenge now lies in refining the workflow to minimize setup time and increase accessibility for clinicians. As technology advances, we may see robotic assistance becoming a mainstream option in implantology, providing greater predictability and precision for both practitioners and patients alike.
