RESUMO
Conventional implant impression techniques may introduce distortions in the framework that can lead to a lack of accuracy of the prostheses. Misfit between the restoration and the implants facilitates the occurrence of biomechanical failures and prostheses complications due to inadequate stress dissipation. Digital impressions present an alternative to eliminate procedural distortions by improving the fit between the restoration and the implants. Among the different types of digital impressions, photogrammetry has emerged as an alternative for multiple implant impressions. This case report describes photogrammetric technique for a full-arch rehabilitation in All-on-four of a 68-year-old patient with a fixed implant-supported restoration on the mandible. Photogrammetric technique has demonstrated to be a successful digital alternative to conventional multiple-implant impression. Esthetics and function remained stable over a follow-up period of 1 year. No biomechanical or biologic complications were observed.
