Summary
This study shows that individually fabricated oral templates ensure accurate dental implant placement. Image-guided surgery using these templates achieved high, reproducible accuracy in phantom models.
Area of Science:
- Dental implantology
- Medical device technology
- Surgical navigation
Background:
- Accurate dental implant placement is crucial for successful outcomes.
- Image-guided surgery offers potential for enhanced precision.
- Customized oral templates can aid in surgical accuracy.
Purpose of the Study:
- To evaluate the accuracy of a system for image-guided dental implant planning and placement.
- To assess the precision of individually fabricated oral templates in a phantom study.
Main Methods:
- A phantom study using identical partially edentulous mandibular models.
- Pilot boreholes were created in a master model for computerized tomography (CT) data acquisition.
- Dental implant placement was planned using image data and reproduced in 10 slave models via custom templates.
- A 3D digitizer arm was used to compare borehole positions between master and slave models.
Main Results:
- The mean deviation of borehole apex positions was 0.50 ± 0.04 mm.
- Accuracy remained below 1 mm in 29 out of 30 tested models.
- High reproducibility was observed, independent of the template or surgeon.
Conclusions:
- Template-based image-guided dental implant insertion demonstrates high and reproducible accuracy.
- This method is a reliable approach for precise dental implant placement.
