Dentin post: A new method for reinforcing the tooth

[摘要] Ideal coronal reconstruction of a fractured tooth is still a challenge for restorative dentistry. Many post systems are available but none of them have all the ideal biological and mechanical properties. In this case report a «DQ»dentin post«DQ» was used for the reinforcement of fractured endodontically treated tooth by virtue of its biomimetic property. Following root canal treatment, a post space was prepared. A direct wax impression was made of the post space. A freshly extracted maxillary cuspid was used to prepare a dentin post, which was then verified in the post space. The dentin post was then luted with dual-cure resin in the canal. Biological dentin posts are considered a good alternative to conventional post systems as they preserve internal dentin walls and provide excellent adhesion and resilience, similar to the natural tooth structure.
