Implant-supported full-arch rehabilitation with immediate loading using two different digital impression techniques:...

Immediate full-arch loading is a highly complex and technique-sensitive procedure. Digital impression techniques aim to replace conventional analog systems to carry out dental treatments in a more predictive, safer, and less time-consuming way. This case report describes a patient with a guarded periodontal prognosis, who was rehabilitated with implant-supported fixed prostheses after full-mouth extractions. Immediate full-arch loading was performed by means of two digital impression systems: photogrammetric technology with PIC dental in the maxillary arch, and MedicalFit in the mandible. Immediate provisional prostheses in acrylic resin (polymethyl methacrylate) were milled and placed within 12 hours after implant placement surgeries. Both provisional structures fitted properly providing adequate esthetics and function. After the implant osseointegration period, final digital impressions were registered, and definitive zirconia full-arch implant-supported prostheses were delivered. The 24-month follow-up did not show biologic or mechanical complications.
