Researchers have developed a novel deep reinforcement learning framework to automate the planning of 3D geometric tooth alignment trajectories for digital orthodontics. The system formulates the planning as a Markov Decision Process, utilizing a Transformer-based agent and a dynamic masking scheme to manage complex spatial interactions and ensure path efficiency while avoiding collisions. A two-stage curriculum learning strategy further enhances training stability and path discovery. Evaluations on a dataset of 10,000 expert-designed treatment plans show the method outperforms existing baselines in safety and geometric efficiency. AI
