Overview: This article provides step-by-step instructions for performing the implant crown and bridge scanning workflow using Dandy Chairside software. Users will learn how to capture opposing arches, emergence profiles, and scanbodies to ensure accurate restoration fit.
Patient Scanning Process
Capturing the Opposing Arch and Gingiva
Scan the opposing arch: Scan the full opposing arch completely before clicking Next.
Prepare the implant site: Remove the healing cap from the implant.
Scan the emergence profile: Scan the emergence profile and the full arch immediately after removing the healing cap.
-
Capture gingival data: Click Start scan and begin scanning directly on the implant site to capture the emergence profile.
Note: Scan the gingival tissue quickly before the tissue collapses.
- Scan adjacent areas: Capture the surrounding gingiva and the contact points adjacent to the implant site.
Verify data: Review the full arch scan for missing data or visible distortion.
Mark the tooth: Select Mark tooth, click the gingival tissue at the implant site, and then click Next.
Verifying Scan Body Seating
Seat the scan body: Place a compatible scan body into the implant site.
-
Capture a radiograph: Use an x-ray unit to capture a periapical or vertical bitewing radiograph to confirm the scan body is fully seated.
Paralleling Technique: Position the sensor or x-ray plate parallel to the scan body angle and direct the x-ray beam perpendicular to the sensor.
Bisecting Technique: Position the sensor or x-ray plate at an angle behind the scan body and direct the x-ray beam perpendicular to the imaginary plane bisecting the scan body and sensor.
Confirm interface: Adjust x-ray opacity and contrast to ensure the internal connection is visible and that no gap exists between the implant and scan body.
Scan the scan body: Begin scanning on the adjacent tooth and use a twist technique to capture the occlusal and lateral surfaces of the scan body.
Finalize arch data: Check the scan for holes, capture any missing data, and click Next.
Aligning the Bite
Replace healing components: Remove the scan body and re-seat the healing abutment.
Prepare the patient: Instruct the patient to bite down firmly and remain still.
Capture bite scans: Start the scanner on the most posterior teeth and move the scanner in an upward and downward motion until the software automatically aligns the bite.
-
Manual alignment: If auto-alignment fails, manually align the arch scans or click Reset to repeat the bite capture.
Review and Finalization
Reviewing Scan Accuracy
Review the completed scans and verify the following details before submission:
Occlusion: Confirm the patient's occlusion is accurately represented.
Data Integrity: Ensure there is no missing or distorted data that could compromise the restoration fit.
Using Review Tools
Undercut Tool: Use this tool to confirm the final restoration can be designed with appropriate contact points.
Stone Tool: Use this tool to evaluate the digital model for any scanning distortions.
Annotate Scans Tool: Edit screenshots of the scans to include specific notes for the dental designer.
Final Steps
Rescan: If a scan appears inaccurate, click A scan looks bad? Re-scan it.
Order: If the scans are accurate, click Start Ordering to proceed to the checkout.
Encode and Scannable Healing Abutment Workflow
For Encode healing abutments, follow this modified scanning sequence:
Preserve the healing cap: Do not remove the healing cap during the initial scan.
Scan the emergence profile: Scan the healing abutment and the full arch together.
Mark the abutment: Select Mark tooth, click the healing abutment, and click Next.
Capture abutment data: Use the twist technique on the adjacent tooth to capture the occlusal and lateral surfaces of the healing abutment.
Complete the case: Capture bite scans and proceed to the Review Steps.
