摘要：
A new method to study the displacements of human teeth in three‐dimensional space is presented. This non‐invasive technique uses recent developments in the double‐exposure pulsed laser holography to measure the displacements of maxillary central incisors of the human with an accuracy of 0.05 μm. The incisor was loaded with a force of 300 grams in the lingual‐labial direction parallel to the occlusal plane. The holographically determined displacements at a point on a crown were then reduced to obtain the center of rotation and also to compute the displacements at the alveolar crestand the apex.
