Summary
This study presents a diagnostic template with a radiopaque marker for accurate 3D bone evaluation using computed tomography. The template can be converted into a surgical guide for precise implant placement.
Area of Science:
- Dental Implantology
- Radiology
- Prosthodontics
Background:
- Accurate implant placement is crucial for function and esthetics in implant-supported restorations.
- Computed tomography (CT) is essential for 3D bone evaluation.
- Artifacts can compromise the accuracy of CT scans.
Purpose of the Study:
- To describe the fabrication of a diagnostic template for artifact-free 3D bone evaluation using CT.
- To introduce a radiopaque silicone marker for enhanced diagnostic accuracy.
- To demonstrate the template's adaptability into a surgical guide.
Main Methods:
- Fabrication of a diagnostic template incorporating a silicone radiopaque marker.
- Utilization of the template with CT for 3D bone evaluation.
- Modification of the diagnostic template into a surgical template by marker removal.
Main Results:
- The diagnostic template with the radiopaque marker facilitated artifact-free 3D bone evaluation.
- The template provided a reliable guide for assessing bone dimensions and implant angulation.
- The diagnostic template was successfully converted into a surgical template.
Conclusions:
- The described diagnostic template is an effective tool for precise 3D bone evaluation in implant dentistry.
- The use of a radiopaque marker enhances CT accuracy for implant planning.
- The template's dual functionality simplifies the transition from diagnosis to surgical guidance.
