Fabrication of three implant-supported crowns using a digital workflow: a case report

Accurate working impression is an essential requirement for the fabrication of implant prosthesis, and digital impressions have recently become more popular. In this case report, a completely digital workflow is introduced for the fabrication of three single-unit screw-retained implant crowns on the posterior maxilla by a dental student, under supervision. This approach involved the use of an intraoral scanner to capture a digital impression of the three implants and their surrounding mucosa, the opposing arch, and occlusion. The use of intraoral scanners and digital impressions illustrated an efficient and patient-friendly method of capturing the necessary data to fabricate a well-fitted prothesis. The aim of this case report is to examine a fully digital approach in the production of multiple single-unit implant crowns.
