ABSTRACT
The purpose of this study is to examine the initial reaction of craniofacial complex to the traction of headgears which are frequent used in clinical practice by using holographic interference method. Changes In the fringe pattern according to the traction conditions (outer bow length, load amount, direction) were compared. Human dry skull was used as experimental material, the results were as follows. 1. The density of fringes Increased with an increase in load. 2. Maxillary headgear affected circummaxillary bones-temporal bone, zygomatic bone, nasal bone, frontal bone, sphenoid bone as well as maxilla. 3. The most upward-backward displacement was observed in a high pull head gear (30degrees), this is though to be a optimal direction for supressing the growth of the maxilla.
