How long does All-on-4 last?

All-on-4 longevity depends on two components:

The implants (titanium posts): - Designed to last a lifetime - 95%+ success rate at 10+ years - Fused permanently with bone - Rarely need replacement

The prosthesis (teeth): - Acrylic: 10-15 years typical - Zirconia: 20+ years typical - Normal wear requires eventual replacement - Can be replaced without new surgery

Factors affecting longevity: - Oral hygiene habits - Regular professional cleanings - Avoiding smoking - Managing teeth grinding - Overall health

How to maximize lifespan: - Water flosser daily - Regular dental visits - Night guard if you grind - Don't use teeth as tools - Quit smoking

Most patients get 20+ years from their All-on-4 before needing prosthesis replacement. The implants themselves typically last the rest of your life.
