What Is All-on-4 / All-on-6 Dental Implants?
Full-arch implant treatment replaces a complete upper or lower dental arch with a prosthesis supported by strategically positioned implants. In an All-on-4 concept, four implants are used; in an All-on-6 approach, six implants support the arch. These labels do not by themselves determine which plan is safer or more appropriate. Bone distribution, jaw anatomy, opposing teeth, bite forces, parafunctional habits, hygiene access, existing infection and prosthetic design all matter.
