Actual (reported)The digital workflow in dental implantology has been used for planning the cases with the intraoral scanners and computer tomography, together helping clinicians to be more accurate and precise. Today, thanks to digital technology clinicians can plan from surgical to the final prosthesis using 3D models and cad-cam machines. The aim of this research is to validate the full digital workflow for the single-tooth implant rehabilitation. A total of 19 patients (22 implants) were included in the present study with mean follow-up time of 2 years. A full-digital workflow was performed on each patient through the design and printing of a surgical guide, the taking of the impression with an intraoral scanner and the CAD-CAM design of the crowns.

Early peri-implantitis and failed osseointegration.
For all patients included in the study, a digital impression was taken using an intraoral scanner. A CBCT exam was performed on the mandibular or maxillary jaw with the missing tooth. The stl. and the dicom. files were then superimposed to allow the surgical planning. Then it was elevated and reflected to increase the volume on the buccal side and exposed the bone surface. After this point, the implant was inserted, and another digital impression was taken. Sutures 6.0 were positioned after healing abutment positioning to stabilize the soft tissues. The final abutment and the provisional were designed and manufactured using cad-cam technology. One week thereafter, definitive abutment was positioned. Provisional restoration was then cemented using provisional cement removing all the possible occlusal contacts both in protrusive and in lateral positions. Three months thereafter, once osteointegration was obtained, definitive zirconia restoration was positioned and cemented.
