Abstract:
It has been a long time since the cephalometrics was introduced to orthodontic field for diagnosis and treatment planning, but it's main concern was limited to hard, skeletodental tissue. It is well known that perioral and facial soft tissue determine the position of individual teeth and that the abnormality in size and shape of the soft tissue are able to cause malformed occlusion. Because of our lack of knowledge about resultant morphologic changes in the relationship between skeletal pattern and specific pattern of lingual and facial muscles, we can't help setting greater value on only abnormalities of teeth in the skeletal intettelationship. In a point of view that the orthodontist is dealing primarily with muscular structures atound the dentition, the tongue, lipsm and cheeks, theregore it may be desirable to estimate these structure and their potentral influence on the dentition on developmental and time base. The author hit upon on idea of the aspect above, so studied on the intermaxillary space and tongue space and this study used the data from cephalometric films of 33 male and 40 female subject aged from 6 to 11 years of normal Korean children. Followion results were obtained: 1. Means and stadatd debiation of Korean children were obtained. 2. Yearly increment of each variables were obtained. 3. There is the correlationship more than average among the variables except posterior intermaxillary heigh item. 4. There are differences between male children and female children in all variables except posterior intermaxillary space item. 5. All variables increased as the age increased except posterior intermaxillary height item of male children.
