Note (General)We used cephalograms to investigate the correlation between the craniofacial morphology of skeletal Class I craniofacial morphology in Japanese adults and the mandibular symphysis, measuring the angles between the mandibular plane and symphysis, and the angles between the symphysis and mandibular central incisor. We observed the correlations between ∠SNA and Thickness Point B and Thickness Pogonion; between ∠SNB and Thickness Point B and Thickness Pogonion; between ∠ANB and Idm - Me; between FMA and Idm - Me, Thickness Point B, and Thickness Pogonion; between IMPA and ∠Idm - X to MP, ∠L1 to Idm – X, Thickness Point B and Thickness Pogonion; and between Gn-Cd and Idm - Me and Thickness Pogonion. In females, correlations were observed between ∠SNA and Thickness Point B and Thickness Pogonion (mm); between ∠SNB and ∠Idm - Me to MP, Thickness Point B, and Thickness Pogonion; between FMA and ∠Idm - Me to MP, ∠Idm - X to MP, ∠X - Me to MP, Idm - Me, and Thickness Point B; between IMPA and ∠Idm - Me to MP, ∠Idm - X to MP, ∠L1 to Idm – X, and Thickness Point B; and between Gn-Cd and Idm - Me. These results suggested the importance of monitoring movement of the mandibular anterior teeth during orthodontic treatment because skeletal differences affect the inclination of these teeth and the morphology of the symphysis.
