  • Treatment provider: Dr. George Michelinakis
  • Solution used: 3Shape TRIOS intraoral scanner
  • By using an intraoral scanner, the patient, who had recently undergone radiotherapy and chemotherapy, did not experience any discomfort or pain associated with the conventional impression technique.


  • Clinical benefits of intraoral scanning. The use of the TRIOS scanner in this extremely challenging case is proven successful and serves as a base for formulating a new digital impression protocol for our referral patients.
  • Fewer impression appointments (one appointment) were needed in contrast to the 2 or 3 appointments needed for conventional impressions for maxillectomy patients.
  • Intraoral STL scan data exported into CAD design software. STL data is imported into CAD software (Dental Wings Productivity Package, Dental Wings) and the obturator and RPD framework were designed.
  • Digital workflow benefit. Communication and treatment planning and execution of the plan with the lab technician is favored tremendously by the digital impression procedure according to Dr. Michelinakis.
