Abstract

Abstract: Objective: To explore the depth of Spee curve between Angle II patients with different ages. Methods: The three-dimensional digital model and lateral slices of the skull of 88 Class II patients who were admitted to the Department of Orthodontics, the First Hospital of Shanxi Medical University from July 2015 to July 2019 were collected. They were divided into two groups according to age: youth group (13 years old ≤ age ≤ 18 years old) and adult group (age > 18 years old). The components were grouped into a high angle group, a mean angle group, and a low angle group according to the GoGn-SN angle. The Spee curve depth of each group was measured and statistical analysis was performed. Results: There was a statistically significant difference in the depth of Spee curve between the Young's class II and the adult group (P＜0.05). There was a statistically significant difference in the depth of the Spee curve between the Class II and different vertical bone types (P＜0.05). Conclusion: The Spee curve depth of Angle II patients gradually decreases with age.

Key words: age, Spee curve, class Ⅱ
