Abstract:

The aesthetic demands of teeth by the public have improved with the increase in the living standard. Orthodontics, which is a method of aesthetic dentistry, is becoming increasingly important. Orthodontic treatment mainly involves the appli-cation of orthodontic force to the teeth and guides the reconstruction of the periodontal tissue, thereby changing the position of the teeth at the occlusal bone. Orthodontic treatment can also improve the dental occlusion caused by dentition crowding and teeth mobility to achieve long-term stability of periodontal tissue. The number of patients with periodontal disease is high in China, and the number of patients with periodontal disease that are eager to receive orthodontic treatment is increasing. Hence, the periodontal status during the orthodontic therapy should be explored along with periodontal therapy and orthodontic treatment. This article briefly demonstrates the assessment criteria of periodontal status before orthodontic treatment, the oppor-tune moment selection for orthodontic treatment, and the supportive periodontal therapy. This study helps dentists develop individualized treatment programs and win a balanced, stable, and aesthetic impression.
