OBJECTIVES: The aim of the present study was to describe a proof of concept digital workflow for the implant-prosthetic treatment in partially edentate patients and evaluate its clinical performance. METHODS: A 55-year-old woman with a Kennedy class III bilateral edentulism in the mandible has been selected for a computer guided implantology according with the Smart Fusion® protocol (NobelBiocare, Kloten, Switzerland). After the template-guided implant placement, an immediate loading of the implants has been performed. QuickTemp conical temporary abutments were selected to deliver immediately prefabricated cement-retained provisionals. Two months after an impression was taken with an intraoral digital scanner (3Shape Trios3, Copenhagen, Denmark). The provisional restoration optical scanning was used to transfer the functionalized prosthetic contour to be duplicated into the definitive porcelain fused to zirconia restoration cemented on customized titanium abutments. RESULTS: A satisfying esthetic and functional result has been achieved. No biological and mechanical complications were recorded. CONCLUSIONS: The investigated fully digital implant-prosthetic protocol provided a smooth, complication free and time effective treatment alternative to the conventional workflow. Besides the fully digital workflow allowed the surgical and prosthetic decision making and the communication within the dental team and with the patient. Further improvements heading to a direct match between the intraoral scan and the CBCT are strongly advised in order to create the so-called virtual patient.
