Summary
This study introduces a 3D software system for oral implantology, improving anatomical visualization and measurement accuracy. The new system enhances precision in dental implant planning, reducing risks associated with traditional 2D methods.
Area of Science:
- Medical Imaging
- Computer-Aided Surgery
- Oral Implantology
Background:
- Traditional 2D software for oral implantology often suffers from volumetric anisotropy and measurement distortion.
- A realistic 3D approach is needed for better anatomical understanding and reduced surgical risks.
Purpose of the Study:
- To develop an integrated 3D software system for oral implant planning.
- To enhance precision and user-friendliness in pre-surgical planning.
- To minimize errors common in existing 2D multi-view systems.
Main Methods:
- Utilized computer graphics to create a fully integrated 3D environment.
- Employed slice interpolation for volume isotropy and accurate measurements.
- Incorporated a radiological mask with radio-opaque markers for precise implant orientation.
Main Results:
- The 3D system achieved superior precision compared to the DentaScan multi-view approach.
- Measurement errors ranged from 0.16% to 0.71%, comparable to or better than the DentalVox tool.
- Validated precision through multiple scan comparisons and performance analysis.
Conclusions:
- The proposed 3D software offers a precise and user-friendly platform for oral implant planning.
- It effectively avoids common errors found in other software.
- The 3D environment supports flapless surgery via robotic integration.
