Future perspectives of digital twin technology in orthodontics☆

Orthodontic treatment is a subject of prevention, treatment and prognostic care for malocclusion. The complexity and multimodality of orthodontic treatment restrict the development of intelligent orthodontics, due to the different growth and development characteristics of patients with different treatment stages and the different prognosis of treatment at different stages. Digital twin technology can effectively solve the problems of orthodontics ,due to its ability to interpret the deep information of big data. Building upon medical knowledge, this paper succinctly summarizes the application of digital twin technology in key areas of orthodontics, including precision Medicine, personalized orthodontic treatment, prediction of soft and hard tissues before and after orthodontic treatment, and the orthodontic cloud platform. The study provides a feasibility analysis of an intelligent predictive model for orthodontic treatment under multimodal fusion, offering a robust solution for establishing a comprehensive digital twin-assisted diagnostic paradigm.
