Lecture Topics
The general theme of the day will revolve around interdisciplinary treatment. The lectures will encompass various areas of this topic with reference to the current evidence. The wisdom of placing implants in the aesthetic zone will be discussed and together with alternative treatment options. The management of cases with missing teeth and bony deficiencies will be explored. Finally, the concepts of implant site preparation and forced eruption to develop bone and soft tissue will be explored. This will inform the audience of the principles that need to be addressed in order to lay the foundation for the interdisciplinary team to carry out the restorative phase of treatment optimally.
