All-On-Four 

What is the All-on-4® treatment concept?
The All-on-4® treatment concept is a cost-efficient, graftless solution that provides patients with a fixed full-arch prosthesis on the day of surgery.
Characteristics include:
- Full-arch rehabilitation with only four implants
Two straight anterior implants and two implants tilted up to 45º in the posterior - Immediate Function (fixed provisional bridge)
For patients meeting criteria for immediate loading of implants - Graftless procedure
Bone grafting is avoided by tilting the posterior implants, utilizing available bone
The All-on-4 treatment concept provides edentulous and soon-to-be edentulous patients with a fixed full-arch restoration on the day of the surgery.
