Mechanical Evaluation of Orthodontic Treatment Using Electronic Speckle Pattern Interferometry - Horizontal Movement of Each Molar

摘要

The deformation of a lower jaw dentition model subjected to horizontal loads to each molar was measured using an electronic speckle pattern interferometry (ESPI) technique. The model consisted of fourteen teeth and a supporting structure, which are made of epoxy resin and polyurethane resin, respectively. A horizontal load was given on each premolar and molar Results indicated that the deformation of the supporting structure depends on the kind of a tooth subjected to the load.
