  • Title: A fully digital approach for implant fixed complete dentures: A case report.
    Author: Meneghetti P, Moura GF, Tavelli L, Li J, Siqueira R, Wang HL, Mendonça G.
    Journal: J Esthet Restor Dent; 2021 Dec; 33(8):1070-1076. PubMed ID: 34213055.
    Abstract:
    INTRODUCTIONS: Intraoral scanner has been widely used for implant impression in partially edentulous cases; however, its accuracy in the impression of full-arch implant is still questionable. CLINICAL REPORT: This clinical report presents a technique to check the accuracy of intraoral scanning for complete-arch implant restorations using an implant index cast (The Glossary of Prosthodontic Terms 9th Edition) and a three-dimensional printed cast. A clinical case of immediate loading on a maxillary edentulous patient illustrates the application of an implant index cast in implant fixed complete dentures (IFCDs). DISCUSSION: The implant index cast was fabricated based on the immediate interim prosthesis and provides effective control of the fit of scanned files and printed models. Therefore, this approach allows a more predictable and accurate fit of the final prosthesis. CLINICAL SIGNIFICANCE: In this article, we present a technique to check the accuracy of the final prosthesis without the need for a conventional impression and final cast in a digital workflow. This proposed approach is demonstrated through a case report of a maxillary edentulous patient restored with immediate loaded IFCDs.
