Periodontal disease is one of the common diseases affecting our population, and the third oral epidemiological survey in China showed that the prevalence of periodontitis in the population over 35 years of age is 80-90%. Periodontal disease is a chronic progressive disease caused by multiple factors, and its development often causes loosening, displacement and elongation of teeth and missing teeth, thus causing secondary malocclusion and occlusal trauma, while malocclusion can further damage periodontal tissues or aggravate periodontal disease. Therefore, proper orthodontic treatment can provide a healthy periodontal environment and a well-functioning dentition for those with malocclusion and poor occlusion, which can contribute to the treatment of periodontal disease and can consolidate the therapeutic effect, and is an important part of comprehensive serial treatment for periodontal disease. However, due to the reduced amount of periodontal supporting tissue (alveolar bone) and slow bone remodeling in the special pathological state of periodontal disease, personalized and precise control of orthodontic force magnitude and tooth movement speed is required. The traditional bracket orthodontic technology cannot achieve personalized and precise control of orthodontic force and tooth movement. In recent years, with the help of computer science, 3D printing technology, material science and biomechanics development, digital invisible orthodontic technology can achieve precise control of orthodontic force and tooth movement, which has become a new strategy for periodontal disease sequential treatment in recent years.
