Topical Collection Information
Dear Colleagues,
Digital technologies are reshaping dental practice. With new materials, new application procedures, and clinical protocols, they are widening the available options for oral rehabilitation. Digital dentistry is constantly contributing to the standardization and quality improvement of dental treatments, facilitating the effectiveness and efficiency of dental offices and laboratories. Transforming all options made available by digital dental technologies into an opportunity to make oral rehabilitation affordable for patients while keeping profitability in mind for oral healthcare providers may be boosted by the dissemination of the current state of the art and research for future applications. As such, the aim of this topical collection is to promote knowledge sharing regarding what is immediately applicable to clinical practice and the current issues or challenges that ongoing or future research can address.

Three-dimensional (3D) printing is transforming dentistry by enabling precise and personalized treatments in prosthodontics, orthodontics, and endodontics. However, challenges such as high costs, material limitations, and post-processing requirements hinder its broader adoption. This scoping review aims to explore and map the breadth of evidence regarding the clinical applications, benefits, and limitations of 3D printing in these disciplines, while identifying research gaps and future opportunities. A scoping review was conducted following the PRISMA for scoping reviews framework. Research from PubMed, Google Scholar, and Scopus was systematically searched, covering studies from January 2006 to November 2024. Key topics included applications, material properties, and technological challenges in prosthodontics, orthodontics, and endodontics. Results: In prosthodontics, 3D printing facilitates the fabrication of crowns, bridges, and dentures with high accuracy, though material strength and stability remain challenges. Orthodontics benefits from 3D-printed aligners and diagnostic models, improving patient comfort and treatment precision, but issues with material durability persist. In endodontics, 3D-printed surgical guides and training models enhance procedural accuracy and educational outcomes. Across disciplines, 3D printing reduces production time and enhances customization but incurs high costs and requires significant post-processing. This scoping review highlights the transformative potential of 3D printing in dentistry, providing an overview of current and future advancements and limitations. While 3D printing has improved precision, efficiency, and patient satisfaction, material and cost-related barriers remain. Future research should address these challenges to expand its clinical applicability and enhance personalized dental care.

Background: Mucostatic impressions have been always indicated in thin, sharp, or flabby ridges, and have been addressed for their beneficial effect on long-term residual ridge stability. Nonetheless, a purely mucostatic impression was not possible until intraoral scans became available. This provides an option for digital removable denture which is biologically sensible but might reduce retention in comparison with a mucocompressive impression with border molding. On the other hand, pressure applied to the mucosa may have harmful effects on the long-term residual ridge stability, causing higher resorption and ultimately reduced denture retention. Hence, the possibility to merge mucostatics and mucocompressive philosophies would be a clinically and biologically sensible option for oral rehabilitation in aging populations where patients will potentially wear dentures for longer periods. This possibility is demonstrated in this technical report with a cast-free digital workflow. Technique: Baseplates for occlusion rims, closely adapted to the mucosa, were designed on intraoral scans of edentulous arches and, once 3D-printed, used to register maxillomandibular relations and information for tooth arrangement, as well as to perform border molding. Occlusion rims were then scanned and, within the 3Shape Dental System 2024 software program, the intaglio surfaces of their baseplates were segmented and inverted to obtain the digital master casts which incorporated the precise reproduction of the molded borders. Then, denture design was performed and manufactured; no limitations regarding manufacturing options are applicable to the presented technique. Conclusions: The potential benefits (i.e., improved retention in the initial period after denture delivery and the preservation of tissues) of the presented digital cast-free workflow, based on merging mucostatic and mucocompressive philosophies to obtain dentures with a mucostatic intaglio surface and functional borders, are sensible clinical outcomes which recommend the clinical application of the technique, although further validation, especially in the long term, is required.
