Esthetic rehabilitation for a Kennedy Class IV patient using detachable 3D printing diagnostic denture and removable partial denture with polyetheretherketone framework

Abstract

For patients with high aesthetic expectation, using removable partial dentures (RPDs) to restore the missing teeth in the aesthetic area rapidly and obtain the patients' approval is challenging. This case described an alternative digital protocol to solve this situation. A detachable 3DP diagnostic denture was involved in the procedure, which not only allowed patient to evaluate the possible outcome of the RPD, but also can be duplicated to form a definitive RPD, by bonding a milled PEEK framework and a customized PMMA dentition containing posts, using a thermoplastic compression molding (CM)process.
