All-on-4 describes a full arch of fixed teeth supported by four implants, with the rear implants angled to make use of available bone and avoid the sinus. Variants using five or six implants are common, and the choice depends on your anatomy rather than on marketing.
It is also the treatment where medical travel arithmetic works best, because the cost difference between a Colombian plan and a US plan is measured in tens of thousands of dollars rather than hundreds. Two sets of flights barely dent that gap.
The structure of the treatment
The distinguishing feature of full-arch work is that you do not go home with a gap. Remaining teeth are extracted, implants are placed, and a fixed temporary bridge is screwed onto those implants — often within the same visit or a day or two after. You fly home with fixed teeth in your mouth.
Those teeth are temporary. They are designed to be functional and to look reasonable while the implants integrate, but they are usually acrylic, they are not the final aesthetic result, and they are not built for years of use.
| Stage | Where | Duration | What happens |
|---|---|---|---|
| Trip one | Medellín | 10–14 days | CBCT, extractions, implant placement, fixed temporary bridge, review appointments and adjustments. |
| The gap | Home | 4–6 months | Integration and gum remodelling, wearing the temporary. Soft diet for a substantial part of it. |
| Trip two | Medellín | 7–12 days | New impressions, framework try-in, aesthetic try-in, then the definitive bridge fitted and adjusted. |
Why the second trip needs proper time
People underestimate trip two. The definitive bridge is not simply collected — it is built through a sequence of appointments with lab work between each one. Impressions are taken, a framework is tried in and checked for passive fit, a tooth arrangement is tried in for appearance and bite, adjustments are made, and only then is the final bridge finished and fitted.
Each of those steps involves a day or more in the lab. Booking five nights for this stage is how people end up rebooking flights. Ten days is a realistic minimum and twelve is more comfortable.
The soft diet is longer than people expect
While the implants integrate, the temporary bridge must not be overloaded. That means avoiding hard and chewy foods for a significant portion of the healing period — the specifics come from your surgeon, but plan on months rather than weeks of genuine dietary restriction.
This matters for planning. If you have a wedding, a major work commitment, or a holiday that revolves around eating, think about where it falls in the schedule before you set the surgical date.
Material choice for the final bridge
The definitive restoration is generally one of:
- Acrylic teeth on a titanium bar. The most economical definitive option. Repairable, lighter, but the acrylic wears and stains over years and teeth can occasionally debond.
- Monolithic zirconia. A single milled ceramic piece. Highly wear-resistant and stain-resistant, heavier, and considerably more expensive. Repair generally means remaking.
- Porcelain layered onto a zirconia or titanium framework. Best aesthetics, with some risk of porcelain chipping under heavy bite forces.
The price spread between these is large and is the main reason full-arch quotes vary so widely. When comparing two quotes, confirm you are comparing the same material — a zirconia quote against an acrylic quote is not a comparison.
Full-arch pricing is normally quoted per arch. If you need both upper and lower, the figure roughly doubles. Some advertised prices refer to one arch with an acrylic provisional and quietly exclude the definitive bridge, which is the most expensive component. Ask directly: does this figure include the final restoration, and for which arch?
Typical 2026 ranges
| Configuration | Medellín | Typical US range |
|---|---|---|
| Four implants, acrylic definitive bridge | $6,500–9,500 | $20,000–26,000 |
| Four to six implants, zirconia definitive | $9,000–13,000 | $26,000–35,000 |
| Extractions, if required | $400–1,200 | $1,500–4,000 |
Typical 2026 ranges for planning purposes, not quotes. Complex cases involving grafting, zygomatic implants, or significant bone reduction sit outside these figures.
Maintenance after you are finished
A fixed full-arch bridge is not removable by you, and food debris accumulates beneath it. Cleaning requires specific technique with interdental brushes and a water flosser, and the bridge should be professionally removed, cleaned, and re-torqued roughly once a year.
That annual maintenance can usually be done by a dentist at home, but only if they can access the system. Before you travel, establish two things: which implant system and prosthetic components are being used, and whether a local dentist is willing to service the work. Turning up at a local practice in three years with an unidentified system and no records is the situation you are trying to avoid.
Who this pathway suits
Full-arch treatment abroad tends to work well for people who have already made the decision that their remaining teeth are not salvageable, who can commit to two trips several months apart, and who have arranged local follow-up in advance.
It works badly for people who are still deciding whether to extract salvageable teeth. Extraction is irreversible, and a plan built around removing teeth that could have been saved is a bad plan regardless of price. If any part of you is uncertain, get an independent opinion from a periodontist at home before committing — one that is not attached to whoever is selling the arch.
