Accuracy of Computer-Aided Dynamic Navigation Compared to Computer-Aided Static Procedure for Endodontic Access...

Area of Science:

• Dentistry
• Endodontics
• Medical Technology

Background:

• Accurate endodontic access cavity preparation is crucial for successful root canal treatment.
• Conventional (freehand) methods may lack precision, potentially leading to procedural errors.
• Computer-aided navigation offers potential for improved accuracy in dental procedures.

Purpose of the Study:

• To compare the accuracy of computer-aided static navigation (SN) and dynamic navigation (DN) systems for endodontic access cavity preparation against conventional manual (MN) techniques.
• To evaluate the precision of SN and DN in achieving planned access cavity parameters.

Main Methods:

• Thirty single-rooted anterior teeth were divided into three groups: SN (n=10), DN (n=10), and MN (n=10).
• SN utilized a stereolithography template based on CBCT and surface scans.
• DN employed a dynamic navigation system for planning and execution. Accuracy was assessed using CBCT and therapeutic planning software.

Main Results:

• No significant differences in accuracy were found between SN and DN at coronal, apical, or angular levels.
• Both SN and DN demonstrated statistically significant improvements in accuracy compared to the MN group across all measured parameters (coronal, apical, angular).

Conclusions:

• Computer-aided static and dynamic navigation systems are effective tools for accurate endodontic access cavity preparation.
• These navigation technologies offer a significant accuracy advantage over conventional manual techniques in endodontic procedures.
