How to take Digi-Denture Impressions

Pre-Scan Checklist

• Ensure the scanner head is clean & connected.
• Set the patient in a reclined position for the impression scan and sitting upright while taking the bite.
• Make sure you have required tools for soft tissue retraction on hand. This is especially important for edentulous patients to maintain a clear view of the scanner head.
• Create the case on the IOS system, including shade, case standard and any additional notes for your technician.

General Scanning Tips

• Move the scanner smoothly and continuously.
• Make sure each image capture frame overlaps the last one.
• Check as you go and at the end for stitching errors and data holes, rescanning affected areas as needed.
• When scanning partially edentulous cases, the key focus should be on a seamless capture of the patient’s remaining dentition and the saddle area. Ensure all teeth are captured first before moving to the edentulous residual ridge.

Scanning Pathways

How to Scan A Reference Denture

If required, reline the existing denture before proceeding to scan it using the following technique. Note that it is essential to capture the edges of the denture during this process to avoid stitching errors.

Example Case Workflows

Case: Partial with stable bite

• Scan upper & lower arches, making sure to include full palate & sulcus.
• Scan the patient’s bite directly (no denture in place).
• Send all scans to lab requesting a Digi-Denture.

Case: Partial without a stable bite

• Scan upper & lower arches, making sure to include full palate & sulcus.
• Scan the existing denture outside the mouth (reline beforehand if necessary).
• Scan relevant arch with denture in situ.
• Scan the patient’s bite directly (no denture in place).
• Send all scans to lab requesting a Digi-Denture.

Case: Fully edentulous with existing denture

• Reline dentures if necessary.
• Scan dentures fully outside of the mouth.
• Scan soft tissue upper & lower.
• Scan the bite with dentures in situ.
• Send all scans to lab requesting Digi-Dentures.

Case: Fully edentulous with no existing denture

• Scan soft tissue upper & lower, send to lab requesting bite block.
• Proceed as usual with bite block stage (marking lip line, centre & canines).
• Scan bite blocks fully outside of the mouth.
• Scan soft tissue upper & lower.
• Scan the bite blocks in situ.
• Send all scans to lab requesting Digi-Dentures.
