All-on-4 · Full-arch implants
All-on-4 dental implants in Miami
A full arch of fixed teeth, held by four to six implants. It doesn't come out at night, it doesn't move when you eat, and in suitable cases your fixed teeth are in place within 24 hours of surgery.
Free for full-arch consultations: exam and 3D CBCT scan included. No obligation.

What All-on-4 is, and what it isn't
All-on-4 replaces every tooth in an arch — upper, lower or both — with one fixed bridge held by four dental implants. The two front implants go in straight. The two back implants are angled, so they can reach firmer bone toward the front of the jaw and stay clear of the sinus above and the nerve below. That angle is often what lets us avoid bone grafting.
The bridge is screwed onto the implants. You don't take it out; only the dentist does, at maintenance visits. There is no adhesive, and on the upper jaw nothing covers the roof of your mouth.
It is not a denture. A denture rests on the gums and moves when you bite. A full-arch bridge is anchored in bone, so you chew with your whole mouth again, with no sore spots or slipping.
All-on-4, All-on-6, full-arch: which one?
These are the same idea with a different number of implants. "All-on-X" and "full-arch implants" are the general names; All-on-4 and All-on-6 say how many implants carry the bridge.
Four implants are enough for many arches. Six spread the load further when there is enough bone, when the bite is heavy, or when you grind your teeth. The number comes from your 3D scan and your bite — not from a package price.
- Four implants when the bone allows a stable plan with fewer fixtures, often without grafting.
- Six implants when there is bone to place them and the extra support is worth it.
- Another approach — individual implants, an implant bridge, or keeping teeth that can be saved — when that serves you better. We'll tell you if it does.
Is it right for you?
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 has stopped working for you. Many people who were told they don't have enough bone for implants are still candidates once the 3D scan shows where the bone is.
At the consultation, Dr. Rodriguez looks at:
- How much bone you have, and where it is solid (this is what the CBCT scan shows)
- The health of your gums and any remaining teeth
- Your medical history and medications — especially diabetes control, smoking or vaping, bone-strengthening medications given by IV, and any radiation treatment to the head or neck
- How you bite, and whether you clench or grind
- What you want from your new teeth
Some of these don't rule treatment out; they change the plan or the timing. If full-arch isn't the right choice for you, you'll hear that plainly, with the options that are.
Your free consultation: exam and 3D CBCT scan
The first visit is free for anyone considering full-arch treatment. It includes a dental exam and a 3D CBCT scan, taken here in the office. There's no obligation to go ahead.
A CBCT scan is a three-dimensional X-ray of your jaws. It shows the height, width and density of the bone, the position of the sinus and nerves, and the roots of any teeth you still have. It is the difference between a plan and a guess, and it's why we don't quote full-arch treatment over the phone.
You'll leave knowing whether you're a candidate, how many implants your plan would use, which teeth would come out, the sedation options, the timeline, and the total cost — in writing, so you can take it home and think.
Please bring a list of your medications. If you've had a CBCT scan elsewhere recently, bring it too.

How treatment works

Stage 01
Consultation & CBCT
A three-dimensional scan shows exactly how much bone you have and where it is solid. It is the difference between a plan and a guess, and it is why we will not quote a full arch over the phone.

Planning and surgical guides
Every implant position is planned on your scan before surgery day. For some cases Dr. Rodriguez uses a printed surgical guide made from that plan; for others he places the implants freehand, following the same plan. Which one depends on your anatomy and the plan — the planning happens either way.
Surgery day
Any remaining teeth are removed, infection is cleaned out, and the implants are placed, usually in a single visit. You choose the level of sedation with Dr. Rodriguez:
- Local anesthesia only — you're numb and awake.
- Oral sedation — a prescribed medication taken before the appointment to help you relax.
- IV sedation — deeper sedation given through a vein.
With any sedation you'll need someone to drive you home and stay with you for the rest of the day.
Fixed teeth within 24 hours
In suitable cases, a fixed provisional bridge is attached within 24 hours of surgery, so you don't go home without teeth. Whether that's possible depends on how firmly the implants are held by the bone on the day. If they need time first, you'll wear a temporary until they're ready, and we'll have told you that possibility in advance.
Healing
The implants bond with the bone over the following months. During that time you eat a soft diet, keep the area clean, and come in for check-ups so we can watch the healing. Many people are back at work within a few days; how you feel depends on how many extractions you had and your own healing.
The final arch
Once the implants have healed, the provisional is replaced with your final bridge. It's designed with our in-house ceramist — tooth shape, length, color and gum line fitted to your face and your bite — and tried in before it's finished.
Living with full-arch implants
Implants can't get cavities, but the gums and bone around them can get infected if they aren't kept clean. Daily care takes a few minutes:
- Brush twice a day, including where the bridge meets the gums
- Clean under the bridge daily with a water flosser or the brushes we show you how to use
- Wear a night guard if you grind
- Come in for maintenance visits; at some of them we remove the bridge to clean it and check the implants
With that care, the implants are meant to last for many years. The teeth on top wear like any restoration and may need repair or replacement over time.
Risks and limitations
This is surgery, and it should be weighed like surgery. Most people heal without problems, but you should know what can happen:
- Swelling, bruising and discomfort for several days after surgery
- An implant that doesn't bond with the bone and has to be replaced
- Infection around implants (peri-implantitis), more likely with smoking, poorly controlled diabetes or poor cleaning
- Temporary or, rarely, lasting numbness of the lip or chin when implants are placed in the lower jaw
- A provisional bridge that chips or breaks during healing
- A period of getting used to speaking and eating with new teeth
Dr. Rodriguez will go through the risks that apply to you at the consultation, and you'll sign a consent that lists them before anything is done.
Cost and financing
We don't give full-arch prices over the phone or online, because they depend on things only an exam and a scan can tell us: one arch or two, four implants or six, how many teeth need to come out, whether any grafting is needed, the sedation you choose, and the material of your final bridge. After your free consultation you get a written plan with the total.
Most patients spread the cost with financing. We work with:
