Implant scanning workflows require the recording of scans containing different information, including the soft tissue, tooth, and implant position of the arch being restored, antagonist arch, and maxillomandibular relationship. Implant scanning workflows vary depending on the implant scanning technique selected for recording the position of the implants being restored and the clinical condition of the patient. This manuscript describes an implant scanning workflow for fabricating an implant-supported prosthesis in which an intraoral photogrammetry system was used for recording implant positions. Additionally, coded healing abutments were used to capture the soft tissue information scan. This coded healing abutments avoided the need for the posterior alignment between the soft tissue and implant position information scans in computer-aided design programs and solved clinical complications such as the movement or dislodgement of the fiducial markers or fixation screws used to guide the alignment of the different scans. Understanding the different digital workflows allows dental professionals to record the necessary information for fabricating implant-supported prostheses efficiently.
