###### Abstract
[30]; the authors considered the characteristics of metallic materials from various aspects, such as tooth anatomy, wear mechanism, dental implants classification, implant materials, and manufacturing techniques. A literature review from the aspect of analyzing shape memory polymeric materials for biomedical applications is presented by [PERSON] et al. [31]; the authors analyzed the type and application of these materials in various fields, such as neuromedicine, dentistry, orthopedics, oncology, etc. A review of polymeric denture base materials is presented by [PERSON] et al. [32]; the authors searched PubMed, Embase, and Scopus databases to determine the types, applications, properties, and manufacturing technologies of these polymers, while the limitations related to the physical and mechanical properties that affect the application of PMMA in dentistry were given. Based on the analysis of the available review papers, the following research gaps were determined: (i) more detailed biocompatibility tests are needed before the materials used in 3D printing in dentistry can be used safely, (ii) a lack of clinical studies on the biocompatibility of polymers in terms of their safe use in humans, (iii) a lack of clinical evidence for titanium cytotoxicity, (iv) limited attention is given to the accuracy, surface treatment, and staining of denture base material, (v) a lack of comparative studies directly comparing 3D printing to traditional technology (considering the fit, comfort, and biocompatibility of dental applications), and (vi) a lack of studies assessing the effectiveness of different surface treatments to mitigate potential plaque accumulation. On the other hand, our research includes the latest use of additive technologies in dentistry from various perspectives over the past 5 years, which is the goal of this systematic review. Depending on the type of material as well as the additive technology used to produce dental applications, the parameters that affect the characteristics of the final product (dental crown, dental prosthesis, etc.) will be determined and discussed in detail. The selected parameters will be compared to determine the most commonly used materials and technologies with the best suitability for dental applications. Limitations that affect the effectiveness of the application of 3D printing in dentistry will also be given. Accordingly, the following RQs were used:  
RQ1: What are the most common applications of additive manufacturing in dentistry?RQ2: Which technologies and materials are most prevalent in dental applications? RQ3: Which parameters affect the quality and safe usage of 3D-printed dental applications? The manuscript is structured as follows: the first section presents the motivation and goal of the research, as well as the research gaps in the review papers, based on which the RQs were formed; the second section provides an in-depth explanation of SLR, including the search strategy and extraction of evidence from the selected studies; the third section presents an initial analysis of the articles chosen to determine the used AM technologies, materials, and their parameters; the fourth section provides detailed research results using synthesized content-based data, which includes descriptive and inferential statistics; the fifth section presents a discussion of the results according to the RQs; and the sixth section contains concluding remarks, limitations and implications, as well as future research.
