###### Abstract  
Additive manufacturing (AM) has emerged as a transformative technology in dentistry, enabling the production of patient-specific dental applications with reduced costs and fabrication times. Despite the growth of applications, a consolidated understanding of current 3D printing technologies, materials, and performance in dental settings remains fragmented. Here, we perform a Systematic Literature Review (SLR) using the PRISMA protocol, retrieving 19 closely related primary studies. The evidence is synthesized across three axes: application domain, AM technology, and critical quality parameters. Dental restorations, prosthetics, crowns, and implants are the most common applications, while fused deposition modeling, stereolithography, digital light processing, selective laser sintering, and laser-directed energy deposition are the most used technologies. AM materials include polymers, metals, and emerging biomaterials. Key quality determinants include dimensional accuracy, wear and corrosion resistance, and photosensitivity. Notably, biocompatibility and cytotoxicity remain underexplored yet critical factors for ensuring long-term clinical safety. The evidence also suggests a lack of in vivo studies, insufficient tribological and microbiological testing, including limited data degradation pathways of AM materials under oral conditions. Understanding that there are disconnects between the realization of the clinical and the economic benefits of 3D printing in dentistry, future research requires standardized testing frameworks and long-term biocompatibility validation. additive manufacturing; 3D printing technology; dentistry; dental application; dental prosthetics; dental implant; dental crown; dental restoration 2  
technologies in dental prosthetics [10; 11]. The application of 3D printing technology enables faster, but equally precise, production of prostheses and implants, as well as simple design changes and the production of products with very complex geometry [12; 13], while the expansion of these technologies will make production prices more affordable. According to Ref. [14], the application and choice of 3D printing technology in dentistry directly depend on the type of material used. Thus, for crowns or bridges made of metal alloys or ceramics, selective laser sintering (SLS), selective laser melting (SLM), and direct metal laser sintering (DMLS) technologies are frequently used, while fused filament fabrication (FFF) or fused deposition modeling (FDM) technologies are most often used for the production of implants and prostheses made of polymer-based composites. However, recently, new materials that need to meet numerous demands about characteristics, such as mechanical and aesthetic, as well as antimicrobial properties, have been increasingly investigated [15]. To identify research gaps and formulate Research Questions (RQs), the following paragraph presents an analysis of review papers. A literature review of the main types of additive manufacturing (AM) technologies with a focus on mechanical characterization is presented by [PERSON] et al. [16]; the authors compared the advantages and disadvantages of the analyzed materials from the aspect of applications in orthopedics, dentistry, prosthetics, etc. A literature review with a focus on the cytotoxicity of acrylic resin materials used in digital light processing (DLP) or stereolithography (SLA) printing technologies in prosthodontic appliances is presented by [PERSON] et al. [17]; the authors searched the Scopus, Embase, and Ovid MEDLINE databases, concluding that there are no significant differences in the biocompatibility of the available resins or washing solutions. A review of the biomedical applications of titanium alloys, where the properties of titanium and its alloys for orthopedic implants and dental prosthetics are analyzed, is presented by [PERSON] et al. [18]; the authors focused on the specific parameters of titanium alloys compared to other materials, as well as the limitations of titanium alloys in biomedicine.
