Hubungan Usia Skeletal terhadap Postur Kranioservikal pada Maloklusi Kelas I, II, dan III Skeletal di RSGM USU

Abstract

Skeletal age is considered the most reliable method for assessing growth in orthodontic treatment planning. The aim of this study was to evaluate the differences and relationships between craniocervical posture and skeletal malocclusions based on skeletal age at different stages of growth. This research is an analytic descriptive study with a cross-sectional design. A total of 72 lateral cephalograms were analyzed, consisting of patients at cervical vertebral maturation (CVM) stages CS1 to CS6 presenting with skeletal Class I, II, and III malocclusions. Landmark identification was performed manually, and measurements were carried out using CorelDRAW software. Differences in craniocervical posture across skeletal Class I, II, and III malocclusions based on skeletal age were analyzed using the ANOVA test. Sex-based differences in craniocervical posture were assessed using the unpaired t-test. The relationship between craniocervical posture and skeletal morphology at each growth stage was analyzed using Pearson’s correlation test. The ANOVA test result showed significant differences during the circumpubertal and postpubertal periods in craniocervical posture among the malocclusion groups. The unpaired t-test result showed revealed a significant difference only in the CVT/HOR and cervical curvature variables between males and females. Pearson’s correlation test result showed indicated a significant relationship between craniocervical posture and skeletal morphology only during the circumpubertal period.
