What does the All-on-4 full-arch implant procedure involve?

The All-on-4 technique uses four strategically placed dental implants in the jawbone to support a full-arch fixed prosthesis. Two anterior implants are placed vertically, while two posterior implants are angled to maximize bone contact and avoid anatomical structures like the sinus nerve. This allows for same-day delivery of a temporary fixed bridge, with a permanent prosthesis fitted after 3–4 months of osseointegration. The procedure is performed under local anesthesia or sedation and typically requires one surgical session.
