Summary

This summary is machine-generated.

Integrating a piezoelectric device (PIEZO) with a dynamic navigation system (DNS) enhances bone-window guided surgery accuracy and efficiency. This PIEZO + DNS approach proved superior to PIEZO + Freehand for bone-window cutting and root-end resection in vitro.

Area of Science:

Dental Surgery
Surgical Navigation
Piezoelectric Devices

Background:

Investigating the integration of piezoelectric devices (PIEZO) within dynamic navigation systems (DNS) for guided bone-window surgery.
Comparing the accuracy and efficiency of PIEZO + DNS versus PIEZO + Freehand (FH) for bone-window cutting and root-end resection (RER).

Purpose of the Study:

To assess the feasibility of combining PIEZO technology with DNS for bone-window guided surgery.
To compare the precision and speed of PIEZO + DNS against PIEZO + FH for specific surgical tasks.

Main Methods:

Forty-eight 3D-printed mandibular molar models were divided into PIEZO + DNS and PIEZO + FH groups.
Procedures included virtual planning, bone-window cutting, and root-end resection using either DNS or a dental operating microscope.
Measurements included 2D/3D accuracy deviations, angular deflection, root resection length/angle, operating time, and mishaps.

Main Results:

PIEZO + DNS demonstrated significantly higher accuracy in bone-window cutting, with reduced deviations and angular deflection compared to PIEZO + FH (P < .05).
The PIEZO + DNS group exhibited a lower resection angle (P < .05) and significantly reduced bone-window cutting and total operating times (P < .05).
No significant difference in the number of mishaps was observed between the groups (P > .05).

Conclusions:

The integration of PIEZO devices with DNS is feasible for bone-window guided surgery.
Dynamic navigation significantly improves the accuracy and efficiency of bone-window cutting procedures.
Further in vitro validation supports the potential of this combined technology in dental surgery.
