Flapless placement of zygomatic implant guided by dynamic navigation safe and accurate

The assessment of the accuracy of flapless placement of zygomatic implants in edentulous maxilla using dynamic navigation.

Results

Osseointegration was achieved for all the implants, except one case in the flapless group. Statistically significant differences in the accuracy of the position of the zygomatic implants was found between the flapless and the conventional groups, measured at the apex and the entry points of the implants (p < 0.01).

The average apical and coronal deviations were 5 mm and 3 mm, respectively; the angular deviation was 6°, and 2 mm vertical apical disparity was detected between the planned and the achieved surgical position.

Perforation of the Schneiderian membrane was noted in three cases, one in flapless group and two in the conventional group.

Flapless placement of zygomatic implants guided by dynamic navigation offered satisfactory safety and accuracy. This is the first clinical trial to prove the feasibility and accuracy of flapless placement of zygomatic implant with minimal morbidity. The study highlights the innovative reflection of the Schneiderian membrane under guided surgical navigation. The procedure can be performed under local anaesthesia, which offers clinical advantages. Adequate training on the use of dynamic navigation is mandatory before its use in clinical cases.
