Abstract
Introduction
This study aimed to compare the effects of static navigation (SN), a dynamic navigation
system (DNS), and the freehand (FH) technique in root end resection and the differences
between these effects according to the level of experience of the operator.
Methods
Maxillary models reconstructed with Mimics software (Materialise, Leuven, Belgium)
were 3-dimensionally printed and divided according to the experimental technique (FH,
SN, or DNS) and the operator (experienced or inexperienced). SN was designed using
3-matic Medical software (Materialise) and printed, and a surgical approach plan for
DNS was established and performed using DCARER (Suzhou, China) software. The accuracy,
efficiency, and safety of the resections were assayed.
Results
The length, angle, volume, and depth deviations of the root end resections were significantly
lower in the SN and DNS group compared with the FH group. SN significantly improved
the efficiency of both operators, whereas DNS only improved the efficiency of the
inexperienced operator. No difference between the SN and DNS groups was found, except
for the time required for the surgery. No mishaps occurred during surgery in the SN
or DNS group. The number of mishaps with the FH technique when used by the inexperienced
operator was significantly higher than that registered for the rest of the groups.
No interaction effect between technique and operator experience level was detected.
Conclusions
Regardless of operator experience, both SN and DNS could improve the accuracy and
safety of root end resection. SN significantly improved the chairside efficiency of
both operators, whereas DNS was more helpful for the inexperienced operator.
