Abstract

Different types of malocclusion have different craniomaxillofacial morphology and occlusal contact, and the crown-root ratio of teeth is closely related to them. Unhealth crownl-root ratio will affect the long-term stability of teeth. Studies at home and abroad suggest that crown-root ratio has ethnic and gender differences. In orthodontic treatment design, orthodontists should analyze the changes in crown length and crown-root ratio according to the patient's gender, ethnicity and other comprehensive judgments, so as to better estimate the treatment risk, maintain the health of periodontal tissues, and then establish a good occlusal relationship, maintain arch stability, and finally obtain a good treatment effect.
