Analysis of stresses on primary anterior teeth during trauma : Influence of root resorption of maxillary primary central incisors

Abstract

We used the finite element method to analyze stresses and displacement during trauma to the maxillary primary central incisors, alveolar bone, and the successive permanent tooth germs for different degrees of primary root resorption. We found that the teeth and alveolar bone were displaced more for teeth that had greater resorption. We also found that greater resorption resulted in less stress in the tooth, although it produced greater stresses in the alveolar bone.
