This study was to evaluate and compare differences of the cervical vertebral skeletal maturityof normal occlu¡þsion and skeletal Class Ill malocclusion. Normal occlusion (172 girls) and skeletal Class Ill malocclusion(191 girls) were classified according to diagnosis stone model and lateral cephalogram of Korean girls aging from 8 to 12 years. The concavity of inferior border, vertico-horizontal ratio of cervical vertebrae were observed and mea¡þsured according to age. Differences of the cervical vertebral skeletal maturity were evaluated. The results were as follows
1. The concavity of inferior border of the 2nd to 6th vertebrae of normal occlusion and skeletal Class III had uniformly increased with age.
2. The vertico-horizontal ratio of the 3rdto 6th vertebrae of girls with normal occlusion and skeletal Class II had uniformly increased with age.
3. There was no significant difference in cervical vertebral skeletal maturity between normal occlusion and skeletal Class II< malocclusion in the concavity of inferior border of the 2nd to 6th vertebrae and in the ver¡þtico-horizontal ratio of the 3rd to 6th vertebrae.
The results in the study indicate that there is no significant difference of cervical vertebral skeletal maturity between girls with normal occlusion and skeletal Class IQ malocclusion.
