Which fixed restoration technique uses four angled implants to support a full bridge for immediate function in the upper arch?
All-on-4 protocol
The All-on-4 protocol is a specific application within the category of Full Arch Restoration, designed to replace an entire set of teeth in either the upper or lower arch using a fixed, non-removable bridge. This technique relies on placing precisely four strategically angled implants, often Endosteal or sometimes Zygomatic in severe cases, to anchor the entire prosthetic bridge. A major advantage of this approach is the potential for Immediate Load protocols, meaning patients may receive a provisional, functional set of teeth on the same day as the surgery, significantly reducing the downtime associated with healing periods required for other methods. The All-on-6 variation is similar but adds two extra implants for enhanced stability, often recommended for patients exhibiting heavy biting habits.
