The term All-on-4, also known as All-on-Four and All-in-Four, refers to 'all' teeth being supported 'on four' dental implants. The name All-on-4 is a registered trademark of Nobel Biocare, used globally for both dental products and services.
All-on-4 (also written All-on-Four or All-in-Four) is a prosthodontic treatment concept in which a full arch of replacement teeth is supported on four dental implants — the name refers to 'all' the teeth being carried 'on four' implants. It is used for total rehabilitation of edentulous (toothless) patients, or of patients whose remaining teeth are badly broken down, decayed or compromised by gum disease, in the upper jaw (maxilla), the lower jaw (mandible), or both. Four implants are placed, positioned towards the front of the jaw where bone density tends to be higher, and these support a fixed prosthesis carrying roughly 10 to 14 teeth. A distinctive feature of the concept is that the prosthesis is fitted immediately — typically within about 24 hours of surgery — rather than after a prolonged healing period. The final teeth are commonly made of PMMA (acrylic) or denture teeth over a titanium framework. The approach has evolved to include an 'All-on-Bar' variation, in which a milled titanium bar is added to link the implants so they work together; this is intended to protect the implants and to provide a longer-lasting restoration than a chairside-repaired conversion denture. All-on-4 is a registered trademark of Nobel Biocare and is used internationally for the associated dental products and services.
Other clinically reasonable options for the same condition. The right alternative depends on the patient's specific anatomy, comorbidities, and goals — discuss with a treating clinician rather than self-selecting from this list.
Two additional implants distribute load better in patients with strong bite forces; higher cost.
Best for partial edentulism; significantly higher cost than full-arch fixed prosthesis.
Lowest-cost option for full-arch tooth loss; removable, lower bite force.

Average recovery for All-on-4 Dental Implants is 0 days. Individual recovery varies — always follow your surgeon’s specific guidance.
Immediate
First 24–48 hours post-procedure. Monitoring, anaesthesia recovery, initial pain management. Most clinics expect you to remain on-site or nearby.
Early recovery
Wound care, swelling or bruising peaks, restricted activity. Typical window for follow-up visits and drain removal if applicable. Travel is usually not advised.
Intermediate recovery
Gradual return to non-strenuous daily activity. Many international patients fly home during this window. Surgeon may require medical clearance for long-haul travel.
Full recovery
Return to full activity, exercise, and work. Final results may still be settling. Final follow-up with local doctor recommended.

All-on-4 is a treatment concept in which a full arch of replacement teeth is supported on four dental implants. The name reflects 'all' the teeth being carried 'on four' implants, and it is used to rehabilitate edentulous jaws or jaws with badly compromised teeth.
Four implants are placed per arch, positioned towards the front of the jaw where bone density tends to be higher. They support a fixed prosthesis that carries roughly 10 to 14 teeth.
A distinctive feature of All-on-4 is that the fixed prosthesis is placed immediately, typically within about 24 hours of surgery, rather than after a long healing period.
The prosthesis teeth are commonly made from PMMA (acrylic) or denture teeth over a titanium framework.
All-on-Bar adds a milled titanium bar that links the implants so they work together. It is intended to protect the implants and to provide a longer-lasting restoration than a chairside-repaired conversion denture.
Yes. All-on-4 is a registered trademark of Nobel Biocare and is used internationally for the associated dental products and services.
All-on-4 Dental Implants is a variant of Dental Implants. See the parent procedure for the broader category context.
