Resumen de: WO2025166097A1
Disclosed are systems and methods of a decision intelligence (DI)-based computerized framework that automatically and/or dynamically implements a color algorithm for performing staining and glazing dental restorations. The framework operates by leveraging determined color variations through AI/ML-based analysis that generate detailed color maps, which can be translated into precise printing instructions controlling the mixture and layering of dental-grade glazing materials. A printing system can employ multiple print heads with varying base colors and opacity levels to create microscopic color gradients and translucency effects matching natural tooth enamel. The disclosed automated processing applies personalized color patterns in microscopically thin layers, ensuring consistent glaze thickness while replicating regional variations across the tooth surface. Such approach eliminates manual glazing variability while achieving superior customization compared to traditional pre-set patterns, resulting in dental restorations that integrate seamlessly with existing teeth.

The present invention relates to a method for activating natural killer cells, comprising a step of providing electrical stimulation to natural killer cells. Specifically, electrical stimulation under predetermined conditions is applied to natural killer cells by applying an electrical stimulation system established through a 3D-printed electrical stimulation device and a function generator. Here, cancer cell-killing ability and calcium ion-mediated mechanisms are analyzed among induced intracellular effects. In addition, with respect to the natural killer cells produced according to the present invention, a method capable of enhancing the efficacy of a cell therapeutic agent without introducing genetic modification is presented, and the cells can be used to study the correlation between the cancer cell-killing ability and the intracellular calcium ion levels of electrically stimulated natural killer cells.
