Area of Science:

  • Endodontic Microsurgery
  • Surgical Navigation Systems
  • Ultrasonic Devices

Background:

  • Investigates the integration of ultrasonic (US) devices into dynamic navigation systems (DNS).
  • Evaluates the feasibility of a fully guided dynamic endodontic microsurgery (EMS) workflow.
  • Compares accuracy and efficiency against freehand (FH) methods.

Purpose of the Study:

  • To assess the feasibility of a fully guided dynamic EMS workflow using US + DNS.
  • To compare the surgical accuracy and efficiency of US + DNS versus US + FH.

Main Methods:

  • Thirty-eight mandibular molars were divided into US + DNS and US + FH groups.
  • Procedures included bone window cut (BWC), root-end resection (RER), root-end cavity preparation (RECP), and root-end filling (REF) under dynamic navigation.
  • Measurements included 3D deviations, resected length, resection angle, RECP deviation, REF depth, and operating time.

Main Results:

  • The US + DNS group demonstrated significantly higher accuracy with lesser 3D deviations for BWC (P < .0001) and RECP (P < .05).
  • The RER angle was significantly lower in the US + DNS group (P < .0001), and REF depth was more precise (P < .05).
  • Both workflows were time-efficient, though US + FH was faster (P < .05).

Conclusions:

  • Integrating US into DNS for a fully guided dynamic EMS workflow is feasible.
  • The fully guided dynamic EMS workflow significantly enhances overall surgical accuracy.
