All-on-4 implants have a track record of durability, with evidence suggesting they can last for 10-20 years, given proper maintenance. However, outcomes may differ based on individual circumstances, including health factors and anatomical differences, which can impact the implants' long-term performance. Routine daily cleaning under the bridge at home and regular 6-month check-ups at the dentist will be essential to getting the implants and bridges lasting as long as possible.
