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).
