Purpose of Review <p>This scoping review aims to explore the impact of four-dimensional (4D) technologies in orthodontic therapy, focusing on the integration of artificial intelligence (AI), dynamic imaging, motion capture, shape-memory materials, and reconstruction techniques. The review seeks to assess how these innovations contribute to enhanced treatment planning, diagnostics, and patient outcomes in orthodontics, highlighting their potential for improving personalized care and precision.</p> Recent Findings <p>The studies reviewed indicate the growing role of 4D technologies in orthodontic practices. Key advancements include the use of time-resolved imaging systems such as CT, MRI, and PET scans, combined with motion capture technologies like Di4D, which allow for precise real-time tracking of facial and skeletal movements. Reconstruction methods, including PRIOR (Probabilistic Image Reconstruction), improve temporal accuracy in imaging. Furthermore, the 3dMD face system offers detailed 3D imaging for facial analysis, while smart materials such as shape-memory polymers enable more responsive orthodontic appliances. AI is also playing an increasingly vital role in treatment planning, helping to predict progress, refine decision-making, and optimize patient-specific treatment strategies.</p> Summary <p>4D technology represents a transformative advancement in orthodontic practice, offering significant improvements in the personalization, efficiency, and overall effectiveness of treatments. The integration of AI, dynamic imaging, motion capture, smart materials, and advanced reconstruction techniques enables clinicians to tailor treatments with greater precision and accuracy, ultimately leading to enhanced patient satisfaction and better long-term outcomes. As these technologies continue to evolve, they hold immense potential for driving future innovations in orthodontics.</p>
