Digital implantological workflow for a CAD/CAM immediate long-term temporary restoration for the edentulous maxilla.

The rehabilitation of the edentulous jaw using angulated implants and screw-retained retrievable fixed prosthetic dentures is a well-established treatment method. Possible advantages include the option to avoid bone augmentation, to provide an immediate long-term provisional restoration, and, where appropriate, to perform a minimally invasive procedure. A variety of prosthodontic solutions are available for the definitive restoration, not least allowing the patient's financial situation to be accommodated. Implementing this concept requires systematic planning and an exacting surgical procedure. It makes sense to rely on a computer-assisted process for this purpose as it standardizes the procedure and makes it reproducible, with all the benefits this entails. The present report highlights the consistent integration of virtual planning and computer-aided design/computer-aided manufacturing (CAD/CAM), from the surgical template to the immediate long-term provisional restoration. The relevant procedures are described in general terms and illustrated by a patient case.
