The current retrospective study was performed in a private clinic in Rome, Italy, where all patients treated by the same operator between January 2017 and June 2020 were consecutively enrolled:

• Patients older than 18 years
• Patients in good health (Asa 1 or Asa 2)
• Patients with healthy periodontium (probing pocket depth ≤ 4 mm, no bleeding on probing)
• Patients not requiring bone augmentation procedures Patients requiring a single implant supported reconstructions were included in the present study.

Surgical and prosthetic workflow For all patients included in the study, a digital impression was taken using an intraoral scanner (CS3600, Carestream Dental, Atlanta, Ga). During the same day, a CBCT (CS9000 3D, Carestream Dental, Atlanta, Ga) 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 (RealGuide, 3Diemme, Cantù, Italy).
