Adhesive procedures have changed the way to restore endodontically treated teeth (ETT). It started with the shift from cast post-and-core to fiber post. The original focus on material strength also shifted towards failure modes, revealing that catastrophic failures are still a concern when restoring ETT even with fiber posts. As an alternative, postless approaches have been proposed in order to improve the chances of repair. The goal of this presentation is to address the current knowledge on adhesive approaches to restore ETT with extensive coronal tissue loss and to present an alternative to the traditional “retention and resistance form” approach . The role of the ferrule, the post type effect on catastrophic failures and postless alternatives as endocrowns and postless build-ups will be discussed. New researches are presenting promising results with a more biomimetic approach for the restoration of broken down ETT, specially in the anterior region. In addition, new research data indicates that bonding enhancement on ETT can be obtained when performing immediate denting sealing prior to root canal (re)treatment, a concept known as Immediate Pre-endo Dentin Sealing (IPDS).​​

OBJECTIVES: At the completion of the course, participants will be able to:

​

• Describe the role of the ferule, post type and presence of a post in the catastrophic failures of endodontically treated teeth

• Understand the importance of preventing catastrophic failures with more biomimetic approaches when restoring broken down endodontically treated teeth

• Comprehend the reasons and steps of Immediate Pre-endo Dentin Sealing (IPDS) concept for bonding optimization in teeth to be submitted to root canal (re)treatment.
