University of Malta Associate Professort Dental Surgery Mater dei Hospital, MSD, Block 1, Level 2 MALTA Msida Msida 2090 551132662049 +35699729634 School of Dentistry, University of São Paulo.

The aim of this report is to present a digital workflow technique to design a customized abutment for provisionalization of an immediate-placed implant based on the natural emergence profile of the tooth to be extracted. The workflow involves the combination of intraoral and CBCT scans, from which three-dimensional (3D) reconstructions of soft tissue and alveolar bone, as well as of the tooth to be extracted are obtained and exported as STL files. The files are imported to a computer-aided design (CAD) software, in which a virtual wax-up and custom abutment design are performed considering the natural emergence profile of the patient's tooth prior to extraction.
