Retreatment of root canal failures provide unique challenges. Many times the canal has been transported and/or the survivability of the tooth is jeopardized due to the removal of excessive amounts of dentin with the original root canal procedure. Successful treatment requires a thorough understanding of the causes of failure, the prognosis of each possible approach to treatment and technologies and materials that allow us the best possibility of biologic success as well as maximum potential for survivability of the tooth. This CE webinar will discuss the causes of failure and the theoretical strategies for success. New technologies will be presented that allow us to disinfect the canal maximally with minimal destruction of the remaining tooth structure. Where retreatment is deemed to be too dangerous or the prognosis is not good enough, surgical approaches with new bioceramic root repair materials will be discussed.
Upon completion of this CE webinar, the student will be able to:
• Understand the causes of root canal failures
• Understand the theoretical approaches to successful retreatment
• Understand which strategies are best in each case for maximal success
• Understand new technologies and materials that allow us a higher potential for successful retreatment

XP-3D Shaper
Brasseler USA’s XP-3D Shaper features exclusive MaxWire Technology that allows the instrument to expand and become more robust when exposed to body temperature. Once an adequate glide path is established, the XP-3D Shaper is able to clean the entire canal without the need for multiple fi les. The XP-3D Shaper features a small flexible core (#30/.01) that is resistant to cyclic fatigue. The unique serpentine design allows the instrument to gently abrade the inner walls of the root canal without the stress associated with conventional NiTi fi les. The XP-3D Shaper features a free-floating adaptive core that allows the smaller central core of the instrument to move freely and adapt to the canal’s natural anatomy.
