Abstract EN
Endodontically treated teeth are restored by different types of posts.
The study is to evaluate the stress distribution in endodontically treated teeth restored with prefabricated post: parallel (with different thread numbers and different materials) and tapered (with different coronal diameter and different materials).
Materials and methods: The models are two-dimensional bucco-lingual section of maxillary central incisor with its supporting structure restored with parallel and tapered prefabricated post mad of two types of material, composite core and ceramic crown.
A 100N force applied separately in three directions vertical, oblique and horizontal.
Results: the maximum equivalent Von Mises stresses of all models subjected to vertical load are located within post material, while with oblique and horizontal loads are located at post surface on the labial side.
Conclusion: Load directions and post materials have much greater effect than post designs on the stress distribution.
The thickness of the dentin wall is directly proportional to the ability of the tooth to withstand the occlusal loads
