Clinical Study Investigating the Efficiency and Complications Related to Two Different Procedures Used for the Preparation of Dentures Applied in Patients With Edentulous

Sponsor: University of Zurich

Summary

The principal aim of the study is to evaluate the prosthetic complications with CAD-CAM fabricated provisional prostheses and denture conversion prostheses after 3 months of function. Supported restorations are now a predictable treatment modality for the rehabilitation of complete and partially edentulous jaws.Immediate loading of the placed implants is performed for the rehabilitation of the edentulous arch to improve patients' function. This can be usually done by converting the existing denture base of the patient or by making a CAD- CAM milled provisional prosthesis integrating digital workflow. A laboratory fabricated denture base can be converted into a screw-retained provisional prosthesis post implant placement. This is known as conversion prosthesis. However, drawbacks of these prostheses include increased chairside time for the clinician leading to inconvenience for the patient and a potential for an error in prosthesis fabrication. With the introduction of CAD-CAM technology, it is now possible to fabricate a provisional restoration using digital workflows. This workflow would help the clinicians save a considerable amount of chairside time and obtain potentially stronger restorations better polished and without contamination of surgical field. Studies assessing the soft tissue response and patient-reported outcome measures between denture conversion and CAD- CAM fabricated provisionals are currently lacking in the literature.
