Overview of Scan Bodies and Intraoral Scanning

  • Introduction to Scan Bodies

    • Scan bodies are transfer copings screwed onto implants.

    • Made from materials like titanium or peak, specific to implant brands.

    • Critical to use the correct scan body specific to the implant type being restored.

  • Benefits of Using Scan Bodies

    • Simplifies the process of implant restoration compared to traditional impressions.

    • Enhances fit and longevity of restorations.

    • Improves communication with labs.

Scanning Process with ARL Scan 3 Intraoral Scanner

  • Software Setup

    • Create a new order and input patient details.

    • Select the relevant tooth (e.g., tooth number 2) and confirm it is implant-based (screw retained/abutment).

    • The implant icon appears in the software indicating scan body scanning.

  • Step-by-Step Scanning Strategy

    1. Initial Scanning Without Healing Abutment

      • Remove the healing abutment and scan the arch, capturing the emergence profile of gingiva.

    2. Scanning the Implant Site

      • Screw in the scan body and scan the specific area; capture the emergence profile and contact areas of adjacent teeth.

      • It is not essential to capture internal details of the implant.

    3. Scanning the Opposing Arch and Bite

      • After scanning the implant site, scan the opposing arch and then the bite, ensuring the healing abutment is returned.

Detailed Scanning Procedure

  • Scanning the Scan Body

    • Clear the area around the implant in the software.

    • Insert the scan body and scan the area without having to rescan the whole arch.

    • Focus on capturing all external surfaces of the scan body; internal screw channels are not critical.

  • Tips for Effective Scanning

    • Align the flat side of the scan body facing the buccal side for accurate positioning.

    • Ensure that the scan body is undamaged and of the correct height for proper exposure.

    • Keep the scan body clean, free from blood and saliva.

Next Steps After Scanning

  • Finalizing Scans

    • Move to opposing arch scan after the scan body scan.

    • Full arch scans are recommended for accurate occlusion.

    • Complete by scanning the bite and ensuring the scan body is removed.

  • Post-Scanning Process

    • Click the final check button; the software processes the scans.

    • Send the scans to the lab for fabrication of the implant restoration.

Conclusion

  • Advantages of Intraoral Scanning

    • Makes implant reconstruction easy and profitable for dental practices.

    • Full arch scans for more extensive restorations may require additional verification techniques.
