At this time LightForce is unable to create other radiographic images out of CBCT scans, Panorex and Cephalometric images must be created and submitted separately. Panorex is require for LightForce treatment

Unsupported Scenarios & Known Issues

  1. Cases where intraoral and CBCT scans were taken at different times with major clinical changes occurring in-between (e.g. tooth extraction, implant addition, primary tooth exfoliation, aligner or appliance treatment)

  2. Staged and Mixed Dentition cases are not currently supported

  3. Roots for canine substitution or any other tooth substitution - Currently roots are not supported for cases where there are tooth substitutions in the LightPlan

Artifacts on roots

Some roots may appear with extra artifacts based on the root segment. These will still be planned.
