Dynamic navigation versus conventional 3D-printed guides in implant surgery: A randomised controlled trial

Area of Science:

• Dentistry
• Surgical Technology
• Biomedical Engineering

Background:

• Precise implant positioning is critical for successful dental prosthetics and maintaining peri-implant health.
• Comparing novel navigation systems with traditional methods is essential for advancing surgical techniques.

Purpose of the Study:

• To compare the precision, surgical efficiency, and short-term clinical outcomes of dynamic navigation (DN) versus static 3D-printed guides (SG) in single-tooth implant placement.

Main Methods:

• A randomized study involving 50 patients, with 25 assigned to DN and 25 to SG groups.
• Key parameters assessed included coronal, apical, and angular deviations, surgical duration, implant stability (ISQ), and patient satisfaction.

Main Results:

• Dynamic navigation showed significantly higher accuracy in implant placement (coronal deviation: 0.90±0.30 mm vs. 1.40±0.40 mm; p<0.001).
• Surgical time was reduced with DN (18±4 min vs. 22±5 min; p=0.002).
• Early implant stability and complication rates were comparable between the two groups.

Conclusions:

• Dynamic navigation enhances accuracy and efficiency in single-tooth implant placement compared to static guides.
• DN presents a clinical advantage for implant dentistry without compromising short-term results.
