A Study on the Correlativity Between the Head and Face and the Maxillary Arch in Korean

the author studied the corelaticity between the head and face and the macillary arch in Korean. This study was undertaker in 336 persons at age from 8 to 19 years who normal occlusion by means of angle´s classification. The followion results were obrained. 1. The corelative coefficient between the Height of Head and Face (H.H.F.) and the Arch Length (A.L.) was 0.203-0.543. 2. The corelative coefficient between the Bizygomatic width (z.w.) and the Bicanine width (c-c) was 0.203-0.543. 3. The corelative coefficient between the Bizygomatic width (z.w.) and the Bimolar width (M-M) was 0.206-0.600. 4. The corelative coefficient between the Face shape (Index a) and Maxillary arch shape(Insex c) was 0.232-0.404. 5. The corelative coefficient between the Face shape (Index a) and Maxillary arch shape(Index d) was 0.221-0.401. 6. There was no corelativity between the Anterior-posterior width of head (A.P.W.) and Arch Length (A.L.), Head shape (Index b) and Maxillary arch shape (Index c, Index d).
