Dynamic Navigation in Implant Dentistry: A Systematic Review and Meta-analysis

Area of Science:

• Dentistry
• Surgical Navigation
• Implantology

Background:

• Computer-guided surgery enhances dental implant placement.
• Dynamic navigation utilizes preoperative planning for guided implant positioning.
• Assessing the accuracy and safety of dynamic navigation is crucial.

Purpose of the Study:

• To evaluate implant placement accuracy with dynamic navigation.
• To determine the frequency of intraoperative complications and implant failures.
• To compare dynamic navigation with static computer-guided surgery and freehand techniques.

Main Methods:

• Conducted comprehensive literature searches (electronic and manual) up to December 2019.
• Performed random-effects meta-analyses on outcome variables including accuracy, complications, and failures.
• Included 32 studies, with 29 reporting accuracy (2,756 implants) and 10 reporting complications/failures (1,039 implants).

Main Results:

• Pooled mean implant placement errors were 0.81 mm (entry) and 0.91 mm (apical).
• Pooled mean deviations were 0.899 mm vertically and 3.807 degrees angularly.
• Dynamic navigation showed significantly lower errors than freehand (P < .01) and similar accuracy to static guidance (P ≥ .05).
• The pooled prevalence of implant failures was 1%.

Conclusions:

• Dynamic navigation demonstrates minimal implant placement errors.
• Its accuracy is comparable to static computer-guided surgery.
• Dynamic navigation is a more accurate alternative to conventional freehand implant surgery.
