Abstract

OBJECTIVE

To estimate and compare the duration of the pubertal growth peak in Class I and Class III subjects.

MATERIALS AND METHODS

The data examined consisted of pretreatment lateral cephalometric records of 218 skeletal Class I or Class III subjects (93 female and 125 male subjects) of white ancestry. The duration of the pubertal peak was calculated from the average chronological age intervals between stages CS3 and CS4 of the cervical vertebral maturation in Class I vs Class III groups (t-test).

RESULTS

In skeletal Class I subjects, the pubertal peak had a mean duration of 11 months, whereas in Class III subjects it lasted 16 months. The average difference (5 months) was statistically significant (P < .001).

CONCLUSIONS

The growth interval corresponding to the pubertal growth spurt (CS3-CS4) was longer in Class III subjects than in subjects with normal skeletal relationships; the larger increases in mandibular length during the pubertal peak reported in the literature for Class III subjects may be related to the longer duration of the pubertal peak.

摘要

目的

估计和比较 I 类和 III 类患者的青春期生长高峰持续时间。

材料与方法

本研究纳入了 218 例白人骨性 I 类或 III 类错颌(93 名女性和 125 名男性)患者的治疗前侧位头颅侧位片。通过比较 I 类和 III 类组颈椎成熟度 CS3 到 CS4 阶段的平均年龄间隔来计算青春期高峰的持续时间(t 检验)。

结果

在骨性 I 类患者中,青春期高峰的持续时间平均为 11 个月,而在 III 类患者中则持续了 16 个月。平均差异(5 个月)具有统计学意义(P <.001)。

结论

与正常骨骼关系的患者相比,III 类患者的生长高峰期(CS3-CS4)的生长间隔更长;文献中报道的 III 类患者下颌长度在青春期高峰时的更大增长可能与青春期高峰持续时间更长有关。
