The science of implantology is always evolving and its something you don’t want to fall behind on. Dr. Alex Volchonok is here to present his work on horizontal and vertical bone ridge dimensional changes in immediate implant placement in a way that is relevant to your practice. Whether you place implants or restore them. Dr. Volchonok will surely advance your foundational understanding about implants!

Lesson Objectives

  1. Understand why the buccal plate is so vulnerable to resorption after a natural tooth is lost 
  2. Develop a foundation for how alveolar bone maintains its blood supply 
  3. Learn how the soft tissue adjacent to an implant can be supported and maintained 
  4. Learn of techniques to achieve a more esthetic outcome with anterior implants
