Complete Digital Restoration: Implant-Supported Prosthesis Using Rapid Prototyping and a Model-Free Approach

This report presents a completely digital workflow utilizing digital intraoral scanning, rapid prototyping techniques, and a monolithic final restoration. A complete fixed prosthesis supported by six implants was used to replace a patient's periodontally compromised mandibular natural dentition. A staged approach was used in which a series of milled and 3D-printed provisional restorations were fabricated to help the patient transition to the dental implant rehabilitation. This cast-free approach allowed for increased patient comfort and greater time efficiency in clinical steps, as each provisional was digitally preplanned and readily available to the clinician before each step.
