The rapid development of digital technology has made the processes of orthodontic data collection, diag⁃ nosis, design and treatment more accurate, comprehensive, convenient and safe and has improved the clinical efficiency of orthodontists. Safe, non⁃invasive, rapid three⁃dimensional facial imaging and digital dental models have enabled ortho⁃ dontists to collect accurately visualized case data. In addition, during diagnosis and design, orthodontists can compre⁃ hensively analyze teeth, jaws, and cranial surfaces in 3 dimensions. Through advances that range from digitized whole⁃ dentition information to computer⁃replicated design and computer⁃aided manufacturing, invisible orthodontic technology without brackets has become one of the best manifestations of the combination of digital technology and oral orthodon⁃ tics. In addition, individualized fixed orthodontic devices have become widely used in orthodontic clinics. In this paper,the applications of digital technology in orthodontic clinics is described. It is hoped that orthodontists will be able to use digital technology rationally to benefit increasing numbers of patients with orthodontic demands.
