Revolutionary fabrication technologies such as three-dimensional (3D) printing to develop dental structures are expected to replace traditional methods due to their ability to establish constructs with the required mechanical properties and detailed structures. Three-dimensional printing, as an additive manufacturing approach, has the potential to rapidly fabricate complex dental prostheses by employing a bottom-up strategy in a layer-by-layer fashion. This new technology allows dentists to extend their degree of freedom in selecting, creating, and performing the required treatments. Three-dimensional printing has been narrowly employed in the fabrication of various kinds of prostheses and implants. There is still an on-demand production procedure that offers a reasonable method with superior efficiency to engineer multifaceted dental constructs. This review article aims to cover the most recent applications of 3D printing techniques in the manufacturing of dental prosthetics. More specifically, after describing various 3D printing techniques and their advantages/disadvantages, the applications of 3D printing in dental prostheses are elaborated in various examples in the literature. Different 3D printing techniques have the capability to use different materials, including thermoplastic polymers, ceramics, and metals with distinctive suitability for dental applications, which are discussed in this article. The relevant limitations and challenges that currently limit the efficacy of 3D printing in this field are also reviewed. This review article has employed five major scientific databases, including Google Scholar, PubMed, ScienceDirect, Web of Science, and Scopus, with appropriate keywords to find the most relevant literature in the subject of dental prostheses 3D printing.

Background Arts‐based methodologies and methods (ABM) can elicit rich and meaningful data with seldom‐heard groups and empower participants in research. Young people with complex psychosocial needs could be better engaged in research using arts‐based approaches to overcome communication and literacy issues as well as distrust of those with power, including researchers. A critical review of the use and impact of ABM among this population is timely. The purpose of this review is to synthesize and examine the experience and use of ABM with young people with complex psychosocial needs. Methods A systematic narrative literature review was conducted with a search of the literature from 2009 to 2021. All abstracts were reviewed independently by two authors and full papers were screened for eligibility against inclusion and exclusion criteria. Data synthesis focused on a descriptive numerical summary and a thematic analysis focused on key patterns across papers relating to the review objectives. Results and Discussion A total of 25 papers were included. The most common issues of focus were mental health (n = 10) and homelessness (n = 11) and methods using Photovoice (n = 12) and Body Mapping (n = 5). Individual interview data (n = 20) were the most commonly analysed, followed by created works (n = 19). Less than half the studies involved young people in the interpretation of the data collected. Knowledge translation was not described in almost half the studies, with public exhibits (n = 7) and forums with service providers (n = 4) being the most common activities. Key themes across the studies were valued over traditional methods in eliciting data, ABM as an approach to engage these young people in research and the impact of the use of ABM on participants and on key stakeholders through knowledge translation. Conclusions The growing field of ABM presents opportunities to enhance research with young people with complex psychosocial needs by promoting meaningful exploration of experiences, engaging participants in research and strengthening knowledge translation. The involvement of young people in the interpretation of data and ensuring that knowledge translation occurs are key areas for future attention. Patient or Public Contribution The findings of this review will inform future research to improve the engagement of young people with complex psychosocial needs in research and promote power sharing between researchers and research participants.
