Rehabilitation of a maxillectomy patient using digital workflow

Patient with Squamous Cell Carcinoma (SCC) of his right premaxilla and nasal cavity in need of a removable partial denture obturator. This case exhibits the merits of intraoral scanning in the hemimaxillectomy patient group.

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.

PREVIEW OF THE CASE

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.
