What Is All-on-4?

All-on-4 is a full-arch restoration built on dental implants (trồng răng implant): four titanium implants are placed into the jawbone and used to support a complete fixed bridge of 10 to 14 teeth. Unlike dentures (hàm tháo lắp), the bridge is screwed in and does not come out. Unlike individual implants, only four anchor points are needed per arch, which means the surgery is shorter, costs less, and is often possible for patients who have lost some bone.

The two back implants are placed at an angle. This tilt lets them engage denser bone further back in the jaw and avoid areas where the sinus sits or where bone height is too low for an upright implant. The angled placement is the defining feature of the All-on-4 concept: it is a deliberate design choice that often lets the system work without bone grafting.

Same-day loading (also called immediate function) is common with All-on-4. Where the bone allows, a temporary bridge is attached during the same surgical appointment, so patients leave the clinic with fixed teeth on the day of surgery. Your dentist decides whether this suits your case.

All-on-4 vs All-on-6 vs All-on-X

Three full-arch implant approaches are common. In Phu Quoc, Tri Hao Dental Clinic publishes prices for All-on-4 and All-on-6. The table below compares them on the points that matter most to international patients.

Candidacy and Contraindications

Who qualifies for All-on-4?

• Full arch tooth loss, or near-complete loss (only a few teeth remaining in the arch)
• Patients with removable dentures seeking a fixed alternative
• Patients with failing teeth (severe decay, gum disease, root fractures) where saving individual teeth is not viable
• Enough remaining bone: the four implant sites need adequate height and width; the angled back implants allow working around some loss
• Non-smokers, or smokers willing to stop for the period before and after surgery that their dentist advises
• Controlled general health: no active infection, blood sugar within a range your doctor is happy with

Contraindications

• Active infection or gum disease: all infection must be cleared before surgery; this may need a preparatory visit or treatment by a local dentist before travelling
• Uncontrolled diabetes: poor blood sugar control impairs healing of the implants into the bone and increases the risk of failure; ask your doctor whether your levels are suitable
• Heavy smoking: nicotine reduces blood supply to bone and raises the risk of implant loss
• Active chemotherapy or radiation to the jaw: implant placement must wait until treatment is complete and the oncologist has cleared the patient
• Bisphosphonate use (high-dose IV): low-dose oral bisphosphonates are generally manageable after a risk discussion; a history of IV bisphosphonates is a contraindication
• Severe bone loss leaving too few implant sites: in these cases zygomatic implants or bone grafting before All-on-4 may be needed; a 3D scan will show this

Bridge Materials: What You Get at Each Price Point

The implants themselves are titanium in all cases. What changes is the bridge: the prosthesis that forms your visible teeth. Three material options are common. Tri Hao says its published All-on-4 price includes all-ceramic teeth; ask any clinic what the temporary and the final bridge are made of before you agree a price.

Note: A PMMA temporary bridge is often fitted on surgery day and replaced by the final bridge at the second visit. This lets the bite be adjusted while the implants heal into the bone, before the permanent bridge is made.

All-on-4 Cost by Country (Per Arch, 2026)

Note: Phu Quoc prices are indicative and converted at indicative rates and rounded; only a written quote for your own case applies. Tri Hao's list has been held on SmileJet since May 2026 and confirmed in quotes to October 2026. Phu Quoc Luxury Dental Clinic does not publish an All-on-4 price. Add flights and accommodation for two trips when you compare.

The Two-Visit Protocol: Day-by-Day

All-on-4 usually follows a two-trip plan. The implants need several months to heal into the bone before the final bridge is made, and this cannot be rushed. The outline below is typical; your dentist sets the schedule for your case.

Aftercare and Hygiene

A fixed All-on-4 bridge can last many years with proper maintenance. Poor hygiene is a common cause of peri-implantitis, an infection around the implant that can cause bone loss and implant failure. These are the essential care steps.

• Water flosser, daily. The space between your bridge and your gums traps food. An oral irrigator is an effective way to clean this space. Use it after meals if possible, and at least every evening.
• Soft-bristle brush twice daily. Use a non-abrasive toothpaste. Clean the bridge surfaces, the gum margins, and the cheek-facing sides thoroughly.
• Interdental brushes. Use around the connections where the bridge meets the gum. Ask your clinic which brush size to use.
• Regular professional cleaning. Your local dentist can clean the bridge and check the gums. Bring copies of your Phu Quoc clinic records to each appointment.
• Avoid chewing ice. Hard, sudden forces are a common cause of PMMA bridge chipping and can stress even zirconia.
• No hard foods while the implants heal. Bones, hard bread crusts, raw carrots and hard nuts are off the list until your dentist clears them.
• Night guard for grinders. If you grind at night, discuss a night guard with your dentist once the final bridge is fitted. Untreated grinding can fracture even titanium-porcelain bridges over time.

Why Phu Quoc Recovery Works for All-on-4 Patients

The week or so you stay for All-on-4 surgery doubles as a rest period after surgery. Many patients treated near home go straight back to work, commuting and daily stress, which is not ideal for recovery.

Phu Quoc changes this. Both clinics are in Duong Dong, the main town, with Long Beach running south of it. Patients there tend to follow the recommended recovery habits naturally: less activity, plenty of fluids, rest and soft food. Vietnamese soups (pho, bun bo Hue), steamed fish, rice porridge and fruit smoothies are easy to find, and many of them suit a post-surgical diet.

Ask your dentist when you can swim after surgery. Snorkelling and diving are generally off the list during the first visit, because of pressure changes and exertion. On the second visit your dentist can tell you whether they are allowed.

Getting there: Phu Quoc International Airport (PQC) is about a 1-hour flight from Ho Chi Minh City. Foreigners arriving directly in Phu Quoc can stay up to 30 days without a visa under the island's special visa exemption; rules change, so check before booking.
