Comparative Evaluation of Accuracy of Adjacent Parallel Implant Placements Between Dynamic Navigation and Static...

Area of Science:

• Dental Implantology
• Surgical Navigation Technologies

Background:

• Accurate placement of adjacent parallel dental implants is critical for successful prosthetic outcomes.
• Traditional static guides (SGs) offer a framework but may have limitations in precision for complex cases.
• Dynamic navigation (DN) presents a potential advancement in guided implant surgery.

Purpose of the Study:

• To compare the accuracy of dynamic navigation (DN) versus static guides (SGs) for simultaneous adjacent parallel implant placement.
• To evaluate surgical time and operator ease of handling between DN and SG techniques.
• To assess the precision of implant positioning in terms of displacement and angulation.

Main Methods:

• A prospective trial involving 20 patients requiring simultaneous adjacent implants, randomly assigned to SG or DN groups (20 implants each).
• Comparison of bucco-lingual displacement, apico-coronal displacement, mesiodistal displacement, and mesiodistal angulation.
• Evaluation of surgical duration and operator comfort by the surgical team.

Main Results:

• Dynamic navigation demonstrated significantly higher precision, with reduced mesiodistal displacement (0.55 ± 0.56 mm vs. 5.61 ± 3.1 mm) and angulation (0.42 ± 0.5° vs. 3.1 ± 2.9°) compared to static guides.
• The second implant in the DN group showed significant improvements in mesiodistal displacement, mesiodistal angulation, and bucco-lingual displacement (p < 0.005).
• Surgical time was longer for DN (60.7 ± 10.1 min) than SG (30 ± 4.5 min) (p < 0.05), while operator comfort was higher with SGs.

Conclusions:

• Both dynamic navigation and static guides enhance implant placement accuracy, but each has unique limitations.
• Optimal prosthetic results depend on careful case selection and the surgeon's proficiency with the chosen navigation technique.
• Dynamic navigation offers superior precision for adjacent parallel implant placement, despite increased surgical time.
