Clinical trial evaluates dynamic navigation system

Dynamic navigation is an advanced technique which allows surgeons to create virtual plans for implant placement procedures and be guided by this plan during surgery. This clinical study assessed the accuracy and clinical outcomes of a new dynamic navigation system. The study also aimed to establish whether or not different surgical techniques would impact the accuracy of the system

The study involved ten patients and 18 implants. Implant site preparation and fixture placement were performed using the dynamic navigation system following the preoperative virtual plan. Ten implants were placed using a flapless technique and the remaining eight were placed using an open-flap approach. Also, eight implant sites were prepared using a combined piezoelectric drill method, while the other ten were prepared using the standard technique.

To determine accuracy, postoperative CBCT scans were compared with preoperative ones and the virtual plan. Distance deviations between the plan and the postoperative outcome were recorded along with the depth of any positioning errors. Other parameters which were investigated included the influence of the technique (flapless vs open flap) and the use of piezoelectric drills.

The results showed a mean deviation of 1.04 ± 0.47mm at the insertion point and 1.35 ± 0.56mm at the apical point. No significant differences between a flapless and open-flap approach were observed. Similarly, there was no difference between conventional and piezoelectric techniques. The study suggests that the use of dynamic navigation could increase safety and improve implant placement outcomes. The authors note that more clinical studies are required to evaluate the full benefits of this technique.

This study was presented as an e-poster at the 2018 EAO Congress.
