ABSTRACT
Aim:
The present study aimed to analyze the stress distribution in the dentoalveolar structures of a maxillary central incisor submitted to two situations of impact loading. Materials andMethods:
The following loading forces were applied using a three-dimensional finite element model a force of 500 N at an angle of 45° on the buccal surface of the crown and a 2000 N force acting in the same direction and surface of the tooth.Results:
Harmful stress was observed in the second situation, suggesting damage to both the tooth and adjacent tissue. However, the damage found in soft tissues such as dental pulp, was negligible.Conclusion:
Injuries resulting from the traumatic situations were more damaging to the integrity of the tooth and its associated hard-tissue structures.
