This narrative review explores the role of additive manufacturing (AM) technologies in the production of dental implants, focusing on materials and key AM methods. The study discusses several materials used in implant fabrication, including porous titanium, trabecular tantalum, zirconium dioxide, polymers, and composite materials. These materials are evaluated for their mechanical properties, biocompatibility, and suitability for AM processes. Additionally, the review examines the main AM technologies used in dental implant production, such as selective laser melting (SLM), electron beam melting (EBM), stereolithography (SLA), selective laser sintering (SLS), and direct metal laser sintering (DMLS). These technologies are compared based on their accuracy, material limitations, customization potential, and applicability in dental practice. The final section presents a data source analysis of the Web of Science and Scopus databases, based on keyword searches. The analysis evaluates the research trends using three criteria: publication category, document type, and year of publication. This provides an insight into the evolution and current trends in the field of additive manufacturing for dental implants. The findings highlight the growing importance of AM technologies in producing customized and efficient dental implants.

Each component implemented in a robotic system requires a priority on low weight, flexibility, and durability. These key parameters for creating a stable yet flexible device can be achieved by applying polymer materials in the construction, not only in the static parts of the skeleton but also in the design and production of robotic grippers. This concise review highlights the possibilities of using polymers as the primary fabrication material for the specific area of “soft grippers” used in dental production. The main part of the article is devoted to analyzing polymer materials—specifically SMPs—their modifications, the characteristics of their primary properties, and the specifics of their use in robotic grippers. The article also provides information on the current state of research conducted over the last decade, through a brief overview obtained from the renowned Web of Science and Scopus databases. As part of the overview, we used basic keywords relevant to the analyzed issue: soft, gripper, and polymer. The review results indicate continuous growth in the number of publications, with the highest increase recorded in 2016 compared to 2016, showing more than a fourfold increase. The lowest increase was recorded in 2020 compared to 2019, where the publication rate was stagnant. The most frequently published documents are Articles, comprising 80.1% to 68.3% (more than 5000 publications). The most popular categories in which documents were published are Engineering 27.1%, (more than 4500 publications) and Materials Science Multidisciplinary 45.2% (more than 180 publications). Based on this review, the importance and need for research into this issue and its analysis can be confirmed, not only in practical applications but also within theoretical reviews and summaries.

This article focuses on research in the machining of zirconia crowns for dental implants. Its goal is to find the most suitable cutting parameters that significantly affect the final surface roughness of the crowns for dental implants. This study conducts investigations and experiments to specify the cutting parameters that achieve the optimal surface roughness of zirconia crowns for dental implants. The experiments were designed to precisely determine the cutting parameters that influence the surface roughness of zirconia crowns. The results of this study provide important insights for improving the manufacturing process of zirconia crowns with the specified most suitable cutting parameters. This research contributes to the enhancement of zirconia crown manufacturing techniques and the improvement in the quality and effectiveness of dental implants.

This study focuses on streamlining the manufacturing process for milling dental prosthetic components from biopolymer materials in order to achieve the best possible surface roughness. Various combinations of cutting parameters were systematically tested in experiments, and their impact on the final surface roughness of the material was analyzed. The study provides a comprehensive view of how variations in cutting speed, feed per tooth and cutting depth affect the final surface quality. The results show that the appropriate configuration of cutting parameters can significantly improve surface roughness, reducing the need for additional finishing and increasing production efficiency. The findings provide valuable information for the manufacture of polymer-based dental prosthetic components, support process optimization, and contribute to the development of accurate and reproducible computer-aided design and computer-aided manufacturing (CAD/CAM) manufacturing procedures. A full factorial design of experiments (DoE) approach was applied to evaluate the influence of cutting speed, feed per tooth, and cutting depth on the resulting surface roughness. The results confirmed that feed per tooth represented the most influential machining parameter affecting the resulting Ra values. The optimized cutting conditions resulted in the lowest surface roughness and improved process stability compared to manufacturer-recommended machining conditions.
