“…These results demonstrate a correlation between the laser-induced increase in surface roughness (as seen in the Ra and Rq values) and an enhancement in hydrophilicity. This is consistent with previous studies that have shown that introducing roughness can amplify the hydrophilic nature of materials with intrinsically hydrophilic surface chemistry [42,43].…”

The performance and long-term durability of dental implants hinge on the quality of bone integration and their resistance to bacteria. This research aims to introduce a surface modification strategy for zirconia implants utilizing femtosecond laser ablation techniques, exploring their impact on osteoblast cell behavior and bacterial performance, as well as the integral factors influencing the soft tissue quality surrounding dental implants. Ultrafast lasers were employed to craft nanoscale groove geometries on zirconia surfaces, with thorough analyses conducted using x-ray diffraction, scanning electron microscopy, atomic force microscopy, and water contact angle measurements. The study evaluated the response of human fetal osteoblastic cell lines to textured zirconia ceramics by assessing alkaline phosphatase activity, collagen I, and interleukin 1β secretion over a 7 day period. Additionally, the antibacterial behavior of the textured surfaces was investigated using Fusobacterium nucleatum, a common culprit in infections associated with dental implants. Ciprofloxacin (CIP), a widely used antibacterial antibiotic, was loaded onto zirconia ceramic surfaces. The results of this study unveiled a substantial reduction in bacterial adhesion on textured zirconia surfaces. The fine biocompatibility of these surfaces was confirmed through the MTT assay and observations of cell morphology. Moreover, the human fetal osteoblastic cell line exhibited extensive spreading and secreted elevated levels of collagen I and interleukin 1β in the modified samples. Drug release evaluations demonstrated sustained CIP release through a diffusion mechanism, showcasing excellent antibacterial activity against pathogenic bacteria, including Streptococcus mutans, Pseudomonas aeruginosa, and Escherichia coli.

“…Conventionally, orthodontic model analysis entails constructing plaster models of the upper and lower teeth and manually taking measurements [9]. Dental models are essential in fabricating the crown prosthesis, where crown refers to the part that covers the top of the tooth, preoperative preparations for implantation, and orthodontic model analysis [10,11,26]. Plaster models are integral to orthodontic patient profiles and are widely used throughout treatment.…”

Accurate analysis of dental models is crucial for diagnosing and treating malocclusion successfully. Traditional measurement techniques, however, often fail to accurately measure teeth in crowded conditions. In this study, we introduce Fusion Analyser, an innovative software tool capable of calculating key dental indicators, thereby advancing the scope of digital dental model analysis. Our unique Fusion Analyser framework employs segmentation discs on teeth to enhance the accuracy of the anterior Bolton's ratio, outperforming the widely-used 3Shape software when dealing with crowded teeth. The Fusion Analyser framework exhibits performance commensurate with the established gold standard, as evidenced by high scores across a range of evaluation metrics, thereby validating its accuracy, stability, and efficiency. The potential of the Fusion Analyser framework as an auxiliary tool for dentists, particularly in diagnosing and strategizing treatment plans for malocclusion, is underscored.
