Title: Clinical workﬂow for digital dentures and future prospects

Abstract

Recent advances in digital technology have enabled the application of digital workflows to complete denture fabrication. This paper outlines a clinical digital denture workflow starting with the digitization of the denture space by three-dimensional (3D) scanning existing dentures, focusing on the approach implemented at the authors’ university. The workflow includes 3D scanning of current dentures, fabrication of 3D-printed copy dentures for impression and jaw relation records, computer aided design (CAD)-based denture design, and final fabrication using either milling or 3D printing. In addition, the paper also covers emerging technologies such as assembly dentures and jetted dentures, and discusses the potential role of digital dentures in improving efficiency and quality of removable prosthodontic treatment in a super-aged society.

Title: Space dentistry: innovations in space-based dental medicine

Abstract

With the advancement of space development and the advent of the era of space tourism, dental care in space environments is becoming a realistic issue. Space-related factors, including microgravity, cosmic radiation, and closed environments, affect systemic physiology as well as jawbone metabolism, the oral environment, and immune responses, potentially altering the onset and progression of dental diseases. This paper outlines the concept and research background of space dentistry and discusses how knowledge obtained from the extreme environment of space may contribute to improving dental care on Earth.

Title: Tooth bleaching, adhesion, and universal-shade resin composites

Abstract

Since the beginning of the 21st century, advancements in adhesive dentistry originating in Japan, together with the integration of novel technologies, have significantly enhanced the ability to address patients’ aesthetic demands. Nevertheless, despite being a minimally invasive procedure and widely requested by patients, tooth bleaching presents clinical challenges, particularly with regard to the execution of adhesive restorative procedures immediately following bleaching. Recently developed universal-shade resin composites, characterized by their superior color-matching performance, may offer a novel clinical paradigm in which restorative treatment is undertaken prior to subsequent bleaching.
