Abstract:
Objective To investigate the correlation between Angle’s class Ⅲ patients’ occlusion plane and anterior overbite by controlling the changes in occlusion plane during orthodontic treatment. Methods In total, 90 Angle’s class Ⅲ adult orthodontic patients were selected as the experimental group, and 30 normal adults were selected as the control group. According to the overbite, the class Ⅲ patients were divided into three groups, and 14 indicators were measured. ANOVA and multiple comparison analysis were used to analyze the difference between class Ⅲ patients, and linear analysis was used to analyze the correlation between anterior overbite and anterior-posterior occlusion plane. Results In class Ⅲ patients, posterior occlusion plane and anterior overbite size were negatively correlated (r=-0.24, P<0.05), whereas anterior occlusal plane and anterior overbite size were positive correlated (r=0.23, P<0.05). Conclusion The shape of the occlusion plane varies in different anterior overbite patients. During orthodontic treatment in different overbite class Ⅲ patients, the vertical height of the posterior teeth and the rotation of the occlusion plane should be controlled.
