Bookimed Expert Insight: While All-on-2 is the most budget-friendly option, data shows it is technically sensitive. Clinics like Luxdentica or Implantis Dental Clinic often suggest All-on-4 for the upper jaw because 2 implants rarely provide enough support for softer maxillary bone. Choosing All-on-2 for the mandible (lower jaw) is a proven strategy for patients with high bone density looking to minimize surgical intervention.
Patient Consensus: Many appreciate the immediate comfort and lower price of All-on-2, but heavy chewers often find the stability insufficient for tough foods. Patients recommend getting a CBCT scan first to ensure bone quality, as failing implants in an All-on-2 setup can lead to expensive redos.
