All-on-4 Implants Explained: Who's a Candidate?

A full arch of new teeth anchored to just four implants. Here's how it works and who it's actually designed for.

All-on-4 was developed specifically for patients missing most or all of their teeth in an arch, offering a fixed, non-removable alternative to traditional dentures using far fewer implants than replacing every tooth individually would require.

How four implants support a full arch

Rather than placing an implant for every missing tooth, All-on-4 uses just four strategically angled implants — two placed straight in the front of the jaw and two angled toward the back, where bone is typically denser. A full prosthetic arch of teeth is then fixed onto those four implants, distributing bite force evenly across all of them.

Who's typically a candidate

  • Patients missing most or all teeth in an upper or lower arch
  • Patients currently wearing a full denture who are frustrated with slipping, discomfort, or diet restrictions
  • Patients with some bone loss who might not qualify for individual implants everywhere, since the angled back implants make use of the bone that remains
  • Patients who want a fixed, non-removable result rather than a removable denture

How it compares to traditional dentures

  • All-on-4 is fixed in place and never comes out, unlike a removable denture
  • It restores significantly more bite force, so diet restrictions are far less limiting than with a traditional denture
  • It stimulates the jawbone the way natural teeth do, slowing the bone loss that accelerates under a denture
  • There's no denture adhesive, clicking, or slipping to manage

What the timeline looks like

Many patients receive a temporary fixed arch on the same day as implant placement — walking out with a functional set of teeth rather than going without. The final, more durable prosthetic arch is fitted a few months later, once the implants have fully integrated with the bone.

Is it right for you?

A 3D scan and consultation can confirm whether your bone structure supports All-on-4 or whether a bone graft would be needed first. For patients tired of a removable denture or facing the loss of most of their remaining teeth, it's worth a conversation before assuming a traditional denture is the only option.
