All-on-X · Full-arch options

All-on-X dental implants in Miami

All-on-X is the family name for replacing a whole arch of teeth on dental implants — fixed teeth that stay in, or a denture that snaps onto implants. Here is how the options compare, and how we help you choose.

Free for full-arch consultations: exam and 3D CBCT scan included. No obligation.

Medically reviewed by Dr. Rodolfo Rodriguez, DMD · Updated

What "All-on-X" means

The X stands for the number of implants holding a full arch of teeth. All-on-4 uses four, All-on-6 uses six, and some plans use five. The idea is the same: instead of replacing each tooth with its own implant, a few carefully placed implants carry the whole arch.

The number isn't picked from a menu. It comes from your 3D CBCT scan — where your bone is, how dense it is, and how you bite. For a closer look at four versus six, read All-on-4 vs All-on-6.

Fixed or removable: the full-arch options

  • A fixed full arch (All-on-4, All-on-6). A bridge screwed onto the implants. You don't take it out; only the dentist does, at maintenance visits. It's the closest thing to having your own teeth again. See All-on-4 dental implants.
  • A snap-in denture on implants. A denture that clicks onto two or more implants, so it stays put when you eat and talk but comes out for cleaning. See implant-supported dentures.
  • A traditional denture. It rests on the gums, with no implants. It's the simplest option, and still the right one for some people. See dentures.

How they compare

  • Stability. A fixed arch doesn't move. A snap-in denture is held firmly but can be removed. A traditional denture relies on fit and suction, and can shift.
  • The roof of your mouth. A fixed upper arch leaves the palate uncovered, so food tastes the way it should. A traditional upper denture covers it.
  • Bone. Implants carry chewing forces into the jawbone, which helps preserve it. Without implants, the bone under a denture slowly shrinks, which is why dentures need relining over time.
  • Daily care. A fixed arch is brushed in place and cleaned underneath with a water flosser. Snap-in and traditional dentures come out to be cleaned.
  • Time. Dentures usually take fewer visits. Implant treatment takes months from start to finish, although in suitable cases fixed provisional teeth go in within 24 hours of surgery.

Who is a candidate

Full-arch treatment is usually considered when most or all of the teeth in an arch are missing, failing, or loose from gum disease, or when a denture no longer works for you. Your general health, diabetes control, smoking or vaping, and certain bone medications are part of the picture — they may change the plan or the timing rather than rule treatment out.

Many people who were told they don't have enough bone for implants still have options once the 3D scan shows exactly where the bone is.

Your free consultation

The first visit is free for anyone considering full-arch treatment. It includes an exam and a 3D CBCT scan taken here in the office, and there's no obligation to go ahead. You'll leave knowing which options fit your mouth, what each involves, and the total for the one you choose — in writing.

What treatment involves

Planning

Dr. Rodriguez plans every implant on your scan before surgery day, and places them with a printed surgical guide or freehand, depending on your anatomy.

Surgery day

Any remaining teeth are removed and the implants placed, usually in a single visit, with local anesthesia alone, oral sedation or IV sedation — your choice with Dr. Rodriguez.

Teeth while you heal

In suitable cases, fixed provisional teeth are attached within 24 hours of surgery. If the implants need time first, you'll wear a temporary in the meantime.

Your final teeth

Once the implants have bonded with the bone, your final arch is made. Fixed bridges are designed with our in-house ceramist and fitted to your face and your bite.

Cost and financing

The cost depends on one arch or two, the number of implants, any extractions or grafting, sedation and the type of final teeth. What affects the cost of full-arch implants explains each factor. We're currently out of network with dental insurance and submit claims as a courtesy. Financing is available:

FAQs

Is All-on-X the same as All-on-4?
All-on-4 is one kind of All-on-X: a full arch on four implants. All-on-X covers four, five, six or more, chosen from your scan.
Which is better, fixed teeth or a snap-in denture?
Neither is right for everyone. Fixed teeth feel more like your own; a snap-in denture usually needs fewer implants, costs less and comes out for cleaning. We'll show you what each would mean for your mouth.
Can I switch from a denture to implants later?
Often, yes. The longer teeth have been missing, the more the bone may have shrunk, so it's worth having a scan sooner rather than later.
How long does full-arch treatment take?
Surgery is usually one visit. The implants then need several months to bond with the bone before the final teeth are made. Your timeline is part of your written plan.
Is the consultation really free?
Yes, for full-arch consultations. It includes an exam and a 3D CBCT scan, with no obligation to start treatment.
