Full mouth dental implants: your options compared

Full mouth dental implants replace all the teeth in one or both jaws using implants. There are four main ways to do it: individual implants with crowns, bridges on several implants, a fixed full-arch bridge on four or six implants (such as All-on-4), or a removable denture that clips onto implants. The right choice depends on your bone, your health, how easily you can clean, and your budget, and every option takes more than one trip to Vietnam.

The American Dental Association describes implants as posts placed in the jaw that act as anchors for replacement teeth. When several teeth are missing, the ADA says they can be replaced with custom-made bridges or dentures that fit your mouth and your implants.

The options at a glance

Option	How it works	Fixed or removable	Best suited to
Single implants	One implant and crown per missing tooth	Fixed	People missing some teeth, with good bone where the teeth are
Bridges on implants	A bridge of several teeth on two or more implants	Fixed	Gaps of several teeth in a row
Fixed full-arch bridge (All-on-4, All-on-6)	One bridge for the whole jaw on four or six implants	Fixed, only a dentist removes it	People losing or missing all teeth in a jaw
Implant denture	A denture that clips onto two or more implants	Removable, you take it out to clean	People who want more stability than a denture, or have a lot of bone loss

Single implants and implant bridges

If you still have some healthy teeth, replacing the missing ones with single implants or short bridges on implants keeps your own teeth where possible. Each implant needs enough bone, and replacing many teeth this way means many implants. The dental implants page explains how a single implant is placed and restored.

Fixed full-arch bridges: All-on-4 and All-on-6

A fixed full-arch bridge replaces every tooth in one jaw with a single bridge screwed onto implants. It stays in your mouth, so it feels closer to natural teeth than a denture.

The research on these bridges is encouraging. A Japanese study of 561 jaws followed for up to 17 years found implant-level survival of 97.4% in the upper jaw and 98.9% in the lower jaw. A study of 943 patients in Lisbon found similar survival with four implants and six implants, 98.4% and 98.7% at 5 years. Both studies looked back at patients of experienced teams, so ask about your own surgeon's experience.

Our guide to All-on-4 dental implants covers this option in detail, including temporary bridges and how the trips work.

Implant dentures

An implant denture, also called an overdenture or snap-on denture, clips onto implants with attachments. You take it out to clean it, but it doesn't slide around like an ordinary denture. A review of implant dentures notes they're often preferred when there's significant bone loss, because the denture's base supports the lips and face. They need maintenance: the most common job is replacing worn inserts in the attachments.

How to choose

Question	Why it matters
How much bone do you have?	Some options need more bone than others. A CBCT scan shows it.
Do you want teeth you can take out?	Implant dentures come out for cleaning. Fixed bridges don't.
How easily can you clean?	Fixed bridges need careful cleaning around the implants. Dentures can be cleaned out of the mouth.
What's your health like?	The ADA says chronic illnesses such as diabetes may interfere with healing, and tobacco slows it.
How many trips can you make?	Every option needs at least two trips to Vietnam, and check-ups afterwards.
What can a dentist at home maintain?	Ask which implant and attachment systems your home dentist can service.

Age on its own is rarely the deciding factor. The ADA says overall health matters more than age, and a 2025 review of 27 studies found good 5-year implant survival in patients over 75. See dental implants for seniors for health conditions and medicines that matter.

Planning full mouth implants in Vietnam

1. Send records for a first opinion. A panoramic X-ray or CBCT scan, photos, and a list of your health conditions and medicines. Dental X-rays and scans explains which files to request.
2. Compare written plans. Ask two or three clinics for a plan that names the option, the number of implants, the implant system, the materials and the number of trips. Our guide to choosing a clinic lists the checks.
3. Plan at least two trips. The ADA says the bone can take up to several months to grow around an implant before the final teeth go on. Planning your visits shows a typical implant trip, and the trip planner builds a sample schedule.
4. Allow recovery time before flying. Read flying after dental treatment and ask your surgeon.
5. Arrange care at home. Fixed bridges and implant dentures both need regular check-ups. Find a dentist at home who will see you before you travel.

Questions to ask the clinic

• Which full mouth option do you recommend for me, and why?
• How many implants will I have in each jaw?
• Which implant system and attachments do you use?
• Will I have temporary teeth while I heal? Fixed or removable?
• How many trips, and how long is each one?
• What does the warranty cover after I fly home?
• Which records will I take home?
