Fully digital versus conventional workflow: Are removable complete overdentures equally good? A randomized crossover trial.

Introduction: Implant-supported removable complete overdentures (IODs) are a common treatment in case of edentulism and malfunctioning of the conventional denture. Manufacturing IODs in a conventional way (C-IODs) is time-consuming, but in a digital workflow, this can be done in three sessions. Digitally produced IODs (3D-IODs) are also more advantageous than C-IODs because lost or broken 3D-IODs can be swiftly reproduced as the digital design is always available.

Fully digital workflow for producing implant-supported overdentures milled from PMMA on titanium bars using PEEK as the female part/sliding mechanism in three clinical visits: A case report.

Purpose: To prove that a fully digital workflow, even for registration of the maxillomandibular relationship, can be employed to produce implant-supported overdentures and demonstrate that CAD/CAM techniques can be used to mill permanent implant-supported overdentures from polymethylmethacrylate discs, using polyetheretherketone as the sliding mechanism.

Materials And Methods: An edentulous 64-year-old woman received six implants in the maxilla after a bone augmentation procedure and two implants in the mandible. Five months after implant placement, intraoral scans were taken of her original complete dentures, of each prosthesis individually, and of both in centric relation, and another was taken of both edentulous arches, including the scan bodies.
