Special Issue Information

Dear Colleagues,

Welcome to this Special Issue of our online journal, delving into the transformative realm of 3D printing in dentistry. As the guest editor, I am delighted to present a collection of articles exploring cutting-edge technologies, influencing factors, and diverse applications shaping this revolutionary field. From custom prosthetics to intricate dental models, 3D printing has redefined precision and efficiency in oral healthcare. Join us on a journey through the evolving landscape where technology converges with dentistry, unraveling endless possibilities that promise to redefine patient care and propel dental practices into a new era of innovation.

In the ever-evolving dental care landscape, the integration of 3D printing technologies serves as a powerful catalyst, reshaping conventional approaches to diagnosis, treatment, and personalized patient care. This compilation delves into the forefront of dental technology, analyzing influential factors steering its trajectory. From materials science advancements to streamlined workflow processes, we explore the complexities of 3D printing applications, showcasing its revolutionary impact on precision dentistry, personalized prosthetics, and the optimization of clinical practices.

This technology accelerates production, reduces costs, and enables personalized solutions, fundamentally reshaping the dental landscape by amalgamating digital design with tangible outcomes for improved patient care and practitioner convenience.

Dental implant bed preparation involves surgical drilling. Heat generated in this process can cause a temperature elevation beyond the bone damage limit (10 °C), affecting the osseointegration of the implant. Surgical templates ensure accurate implant placement, but they limit the access of the irrigation fluid. This study evaluated the hypothesis that surgical guides with internal cooling prevent bone heating more effectively than classical guides. To eliminate biological variability, this study was conducted on artificial bone pieces that mimic the bone density of the human mandible. We created a surgical template that incorporated four pairs of guides—one classical (CLA) and one with internal cooling (INT) in each pair. For each specimen, we randomly selected the type of surgical guide to start with and performed four osteotomies with a 2.7 mm-diameter drill; then, we widened each hole with a 3.3 mm drill and finalized it with a 3.7 mm drill. The temperature was recorded by thermocouples placed at 0.8 mm from the prospective edge of the final osteotomy. In 168 measurements (12 osteotomies on 14 specimens) conducted for each type of surgical guide, the mean temperature rise was 7.2 ± 4.9 °C (mean ± standard deviation) for CLA and 5.0 ± 3.8 °C for INT. The mean differences between temperature elevations were 1.5 °C, 2.1 °C, and 3.0 °C for the first, second, and third drill, and they were statistically significant: the p-values of Student’s t-test were 0.004, 0.01, and 0.001, respectively. Although the mean temperatures remained safe, temperature rises exceeded 10 °C in 23.8% (9.5%) of the osteotomies performed in the presence of CLA (INT). Taken together, our results suggest that surgical guides with internal cooling ensure a significant drop in the temperature rise caused by implant site drilling. Full article

Dental prostheses have been fabricated using various selective laser melting (SLM) machines; however, the impact of the type of machine on the microstructure and mechanical properties of Co–Cr–Mo alloys remains unclear. In this study, we prepared samples using two SLM machines (the small M100 and mid-sized M290) with different beam spot sizes (40 and 100 µm, respectively). The microstructures and tensile properties of the heated (1150 °C for 60 min) and as-built samples were evaluated. The grain sizes of the M100 samples were smaller than those of the M290 samples due to the small beam spot size of the M100 machine. Both heated samples exhibited recrystallized equiaxed grains; however, the amount of non-recrystallized grains remaining in the M290 sample exceeded that in the M100 sample. This suggests that the M100 samples recrystallized faster than the M290 samples after heating. The elongation of the M100 samples was higher than that of the M290 samples in the as-built and heated states, owing to the smaller grain size of the M100 samples. A comparison of the M100 and M290 SLM machines indicated that the M100 was suitable for producing dental prostheses owing to its good elongation and rapid recrystallization features, which shorten its post-heat-treatment duration.
