実時間ホログラフィ干渉法による中顔面骨の変形解析

Abstract

The displacement of human dried facial bone was measured and considered by real time holographic interferometry, when the loads of various directions and amounts were applied on the zygomatic bone and maxilla. The relations between places subjected to the loads and their deformations were discovered from consideration of the fringe pattern. The fracture patterns of maxilla and zygomatic bones were classified into 12 groups according to the loading areas. For the orbital floor, the fracture patterns were summarized in 4 groups. These results give suitable aspects for surgical treatment of the fracture of mid-facial bone.
