초록
The present study was conducted to assess the growth changes of human chin in childhood and adolescence at various stages of skeletal maturation using metallic implant installed in mandibular body. Lateral cephalographs including 23 subjects (9 males and 14 females) between 7-18 years old were used, which had been taken at University of California in San Francisco and kept at University of the Pacific. Three lateral cephalographs were chosen for each subject according to CVM (Cervical Vertebral Maturation) method (CVM stage 1 to 2, CVM stage 3 to 4, and CVM stage 5 to 6) which assess the extent of the skeletal maturation using the second, third, and fourth cervical vertebrae. V-ceph was used in order to mark the 8 landmarks (S, N, A, B, Pog, Me, Go, Imp) on lateral cephalographs and obtain 8 angular and linear measurements(ANB, SNPog, SN-GoMe, Imp-B, Imp-Pog, B-Pog//GoMe, GoMe B, GoMe Pog). Among 8 measurements, ANB, SNPog, SN-GoMe, B-Pog//GoMe, GoMe B showed statistically significant growth changes at various stages of skeletal maturation according to CVM method, while there were no significant differences on Imp-B, Imp-Pog, GoMe Pog. The results suggest that the increasing prominence of human chin is greatly influenced by the vertical growth of B point area, in addition to the change and growth in chin and mandible proper.
Abstract
The present study was conducted to assess the growth changes of human chin in childhood and adolescence at various stages of skeletal maturation using metallic implant installed in mandibular body. Lateral cephalographs including 23 subjects (9 males and 14 females) between 7-18 years old were used, which had been taken at University of California in San Francisco and kept at University of the Pacific. Three lateral cephalographs were chosen for each subject according to CVM (Cervical Vertebral Maturation) method (CVM stage 1 to 2, CVM stage 3 to 4, and CVM stage 5 to 6) which assess the extent of the skeletal maturation using the second, third, and fourth cervical vertebrae.
