Accuracy of automatic and manual dynamic navigation registration techniques for dental implant surgery in posterior sites missing a single tooth: A retrospective clinical analysis

ObjectivesTo assess the relative accuracy of manual (U-shaped tube) and automatic (two-in-one) dynamic navigation registration techniques for implant surgery performed in posterior sites missing one tooth. Materials and MethodsThis study included 58 partially edentulous patients with 58 implants, including 31 and 27 in the manual and automatic groups. Deviations between the planned and actual implant placement were assessed. ResultsThe angular deviation in the overall study cohort was 2.54 +/- 1.21 degrees, while the 3D deviations at the implant platform and apex were 0.90 +/- 0.46 mm and 1.04 +/- 0.47 mm, respectively. The respective angular deviations in the manual and automatic groups were 2.82 +/- 1.17 degrees and 2.21 +/- 1.19 degrees (p > .05), while platform deviations were 0.89 +/- 0.48 mm and 0.91 +/- 0.45 mm (p > .05), and apex deviations were 0.99 +/- 0.48 mm and 1.11 +/- 0.46 mm (p > .05). No significant differences in absolute buccolingual, mesiodistal, or apicocoronal deviations were detected between these groups at either level (p > .05) nor were did deviation distributions differ in the buccolingual, mesiodistal, or apicocoronal directions at the platform or apex levels (p > .05). ConclusionsManual and automatic dynamic navigation registration techniques can achieve excellent accuracy when placing implants in posterior sites missing a single tooth. The two-in-one automatic registration technique can reduce the amount of time and intraoperative steps necessary to complete the registration process relative to the manual U-shaped tube registration technique. Further follow-up studies are necessary to expand on these results.

Automated summary

This study compared the accuracy of manual and automatic dynamic navigation techniques for implant surgery in posterior sites missing one tooth. The results showed that both techniques achieved excellent accuracy with minimal deviations. There were no significant differences between the manual and automatic groups. Therefore, both navigation techniques can be used effectively for implant placement in posterior sites.
