Abstract: Objective This study aims to compare stresses of the mandibular first premolar restored with master fiber post only or combined with auxiliary fiber post.Methods A total of 19 normal mandibular first premolars were selected and scanned by cone-beam computed tomography(CBCT). Premolars with flat root canal were selected and treated using standard randomized controlled trial procedures and post-space preparation. Then, a repeat CBCT scan was conducted on the prepared tooth. Three-dimensional models were established according to results of CBCT scan. The model using the master fiber post only was named A, and another model that used master fiber post in combination with auxiliary post was labeled B. Two models were loaded in three different directions, and corresponding stress distributions were analyzed. Results After comparing A and B, results showed that stress distribution between tooth tissue and fiber post features no significant difference with loading force angle and long axis of tooth. Peak value of von Mises stress in models A and B increased significantly as loading angle increased.Conclusion Auxiliary fiber post poses minimal influence on premolar restoration after exposure to stress. However, this influence intensifies on loading angles.

Key words: three-dimensional finite element analysis, stress, master fibre post, auxiliary fibre post, premolar
