Tech tip: Intraoral scanning vs. traditional impressions

There are a lot of options out there for capturing dental impressions. ClearCorrect accepts scans from most intraoral scanners on the market, including CEREC,Ormco Lythos3M True DefintionCarestreamiTero3Shape TRIOSE4D PlanScan and Motion View Ortho Insight 3D scanners.

While we happily accept either scans or traditional PVS/VPS impressions, we also know that 3D technology has had a significant impact on dentistry and many doctors are switching to intraoral scanners.

If you're asking yourself whether you should switch, this comparison might help you make your decision:

Advantages of scans

  • More comfortable for patients
  • Fewer “re-takes”
  • Less staff time per impression
  • Higher accuracy
  • Minor errors can usually be patched
  • No need to stock expensive PVS material or impression trays
  • No shipping hassles or delays
  • Records can be submitted electronically for faster turnaround
  • $25 discount on ClearCorrect cases
  • 3D models can be stored indefinitely without taking up physical space
  • Digital model can be reviewed in real-time instead of waiting for setup

Disadvantages of scans

  • Accurate results depend on mastering new techniques
  • Some scanning carts take up space in the office
  • Data can be incomplete
  • Upfront integration costs
  • Per-scan or subscription costs for some models
  • Can't be used to pour up stone models

Advantages of traditional impressions

  • Familiar impression-taking technique
  • Minimal upfront integration costs
  • Common, widely-available materials

Disadvantages of traditional impressions

  • Taking high-quality impressions requires practice
  • Impressions must be shipped for processing
  • Fewer conversion steps mean less degradation of quality
  • Higher costs for materials and staff time
  • Space & cost to stock materials & supplies (i.e. impression trays, light body and heavy body PVS, adhesive, etc.)
  • Patients find the process uncomfortable
  • Defects in the impression require a re-take which can be costly in terms of time and inconvenience
  • Impressions cannot be easily patched to fix certain spots, they must be retaken from scratch
  • Defects in impressions are not always visible to the untrained eye
