A Completely Digital Workflow of an Interim Complete Arch Fixed Implant Prosthesis Using a Novel High-Performance 3D Printed Polymer

Abstract

The advent of osseointegration has offered a quantum shift in treatment planning patients with missing teeth. Patients with a terminal dentition or edentulous arch have become candidates for a fixed rehabilitation with immediate function. A striking limitation of this modality, however, has been the mechanical failure rate of the reconstructions, especially the interim prostheses. This clinical report describes a completely digital workflow and additive manufacturing of an interim complete arch fixed implant prosthesis, immediately placed after extraction. The prosthesis is supported by four immediately loaded implants on the maxillary arch, using stackable guides and the use of a novel 3D printed high-performance UDMA to improve precision, efficiency, and prosthetic stability.
