Learning outcomes:
At the conclusion of this session, the audience will be able to:
- Understand backgrounds for the development of the All-on-4 concept
- Describe the patient benefits for a treatment concept that is based on a maximum patient comfort on minimal amount of implants.
- Explain the clinical benefits and the clinical significance for all-on-4 concept compared to other concepts using evidence-based science.
- Discuss the long-term clinical results.
- Summarize why a fixed overdenture on four implants can be considered as a serious treatment alternative for a removable overdenture on two implants.
