Overview: Evaluate immediate denture scans for palate data, retro-molar pads, and bite alignment to ensure accurate appliance fit and production.
Immediate Denture Scan Requirements
To produce a high-quality immediate denture, the digital scan must meet specific anatomical and alignment criteria. Ensure each denture scan includes the following characteristics:
Vestibule and Vibrating Line Extension: The denture scan must capture the full extension of the vestibule and the vibrating line.
Anatomical Arch Coverage: Capture the full arch from the molar region to the midline.
Data Integrity: Verify that the denture scan has no missing data points or "lifted" sections where the scanner lost tracking.
Bite Alignment: Ensure the bite scan shows an accurate relationship between the upper and lower arches.
Common Immediate Denture Scan Errors
Scanning errors can lead to ill-fitting appliances or production delays. Avoid these common issues during the denture scanning process:
Missing Palatal Data: Do not submit scans with holes or missing data in the palate area, as this data is crucial for denture stability.
Incomplete Retro-molar Pads: The denture scan must extend to include the retro-molar pad to ensure proper posterior support.
Misaligned Arches: Review the bite relationship to confirm the arches are not shifted or inaccurately recorded in the software.
