| Research Abstract |
The purpose of this study was to examine the possibility of three-dimensional craniofacial form control by the growth control of the suture using i nternalized d evice made of Ni-free Ti-based s hape m emory a lloy from the bi omedical engineering aspect. The animal experiment model which loads mechanical force on the suture of a growth phase rat cranium was produced. Biological and m orphometric al evaluation for the reaction of the suture against the mechanical stress was done in this study.
As a result, it was suggested that three-dimensional form control of craniofacial regions could be performed by the device using a new shape memory alloy.
