SPG Webinar: Improving Posts & Cores

Presenters: Dr Ben Lee, Dr Johnson Chou, Dr Agnes Lai & Dr Zoe Potres Sometimes an endodontically treated tooth may require a post and core before the definitive crown. But when do you need a post, and which type of post and core should you place? When should you choose between direct vs. indirect posts? Can posts even “strengthen” teeth? These questions are often debatable and the answers can vary significantly between clinicians. This webinar aims to explore the best available evidence and to provide some clarity on this topic. We will cover direct vs. indirect posts including post materials of: metal, fibre reinforced composite resin, ceramic and gold. Questions that will be answered in this webinar include: - When do you need to place a post? - When should you consider an indirect post and core? - How to predictably carry out an indirect post and core? - Flexible vs rigid post, which is better? - Which post is the “best”? - What is the best way to prepare a post-space? - What bond should you use? - What core material should you use?
