Dynamic Navigation in Endodontic Surgery: A Systematic Review

Area of Science:

• Dental surgery
• Endodontics
• Medical technology

Background:

• Evidence on dynamic navigation systems (DNSs) in endodontic surgery is limited compared to other fields.
• This review assesses DNS accuracy, reliability, and clinical impact in endodontic surgery.

Purpose of the Study:

• To systematically review the accuracy and reliability of dynamic navigation systems (DNSs) in endodontic surgery.
• To evaluate osteotomy parameters, procedural duration, surgeon expertise, healing outcomes, complications, and patient/dentist feedback.

Main Methods:

• Systematic review following PRISMA guidelines, searching major databases up to April 2025.
• Included studies involved human subjects undergoing endodontic surgery with DNS assistance.
• Data extracted included accuracy metrics (deviations, angular deflection) and procedural details.

Main Results:

• Fourteen studies with 240 roots analyzed showed high DNS accuracy (e.g., 1.17mm platform deviation, 2.29° angular deflection).
• Root-end resections averaged 3.02mm length and 7.49° angle deviation; DNS-assisted steps took 5.6 min.
• Favorable healing outcomes and infrequent complications were reported.

Conclusions:

• Dynamic navigation systems demonstrate satisfactory accuracy and efficiency in endodontic surgery.
• DNS use is associated with positive healing outcomes and low complication rates in current studies.
• Limited evidence and study heterogeneity necessitate further research to define clinical implications.
