Abstract
Orthodontics has undergone a revolutionary transformation during the twenty-first century due to rapid advancements in digital dentistry, artificial intelligence, biomaterials, three-dimensional imaging, computer-assisted treatment planning, and esthetic orthodontic systems. Traditional fixed mechanotherapy has increasingly evolved into a sophisticated interdisciplinary specialty integrating biomechanics, software engineering, regenerative biology, craniofacial imaging, and minimally invasive therapeutic strategies. Across the world, the orthodontic industry has witnessed accelerated adoption of clear aligners, temporary anchorage devices (TADs), self-ligating brackets, CAD/CAM systems, teleorthodontics, and AI-assisted predictive treatment planning. India, one of the fastest-growing dental healthcare markets globally, is simultaneously experiencing substantial expansion in orthodontic awareness, digital dental infrastructure, aligner manufacturing, and cosmetic dentistry demand. However, disparities remain in affordability, technological accessibility, training standards, and rural orthodontic care. This cross-sectional comparative review critically evaluates the latest developments in orthodontics in India and globally, focusing on technological innovation, treatment efficiency, clinical outcomes, patient-centered care, digital transformation, and future trends.

Introduction
Orthodontics has historically represented one of the most technically demanding and scientifically dynamic branches of dentistry. Traditionally centered upon fixed appliances, arch wires, brackets, and biomechanical tooth movement, the discipline has progressively evolved into a technologically integrated specialty combining engineering, computer science, craniofacial biology, imaging sciences, biomaterials, and precision digital healthcare.
The global orthodontic landscape has changed dramatically over the past two decades because of increasing esthetic awareness, patient demand for minimally visible appliances, advances in biomedical imaging, and the emergence of digital dentistry ecosystems. Contemporary orthodontics now incorporates intraoral scanners, computer-assisted treatment planning, artificial intelligence-based movement prediction, 3D printed appliances, robotic aligner fabrication, remote treatment monitoring, and skeletal anchorage systems.
