Purpose:
To study the stresses and movement of central incisor with three-dimensional dynamic finite element method, in order to understand and describe the process of occluding.
Methods:
A three-dimensional dynamic finite element model of central incisor was established, and the definition of contact between the surfaces of occlusive contact was defined as Hard Contact (ABAQUS) to simulate the process of occluding.
Results:
The stresses on the central incisor varied with the time of overbite and the movement of teeth during dynamic occluding. Higher stresses were observed in the areas of buccal-lingual cervical marginal on the upper teeth, but in the near-far cervical marginal on the lower.
Conclusions:
Dynamic finite element method can help to picture the process of articulation and the conditions of teeth momentarily, and could be used for the research of oral biomechanics effectively.
