What is All-on-4?

All-on-4 is a full-arch tooth replacement technique. Four titanium implants are placed into the jawbone and a complete set of fixed prosthetic teeth is attached to those four implants. The result is a permanent, non-removable bridge that looks and functions like natural teeth.

The technique was developed by Nobel Biocare and relies on a specific placement geometry. The two front implants are placed vertically. The two rear implants are placed at an angle of up to 45 degrees. This angled placement serves two purposes: it allows the implants to engage more bone volume in the jaw, and it positions the rear anchor points further back in the arch without the need to go into areas where nerves or the sinus cavity might obstruct vertical placement. This is why All-on-4 can work in jaws with moderate bone loss where traditional implants might require bone grafting.

The bridge is attached to the four implants on the day of surgery. This immediate loading means patients leave the clinic the same day with a full set of teeth. That provisional bridge is a temporary one made from acrylic. The permanent final bridge is fitted at the second visit, 3-6 months later, after the implants have bonded fully to the bone.

The procedure replaces one full arch (either upper or lower jaw) per surgical session. Patients needing both arches replaced require two sets of implants and two bridges. Pricing in this guide is quoted per arch.

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

Three related treatment approaches are often grouped together. Here is how they differ:

The terms All-on-4 and All-on-X are sometimes used interchangeably by clinics. When you receive a treatment plan, confirm the exact number of implants and the implant brand being recommended.

Who is a Good Candidate?

All-on-4 suits a wide range of patients with full-arch tooth loss or failing dentition. You are likely a strong candidate if:

• You are missing most or all teeth on one or both arches
• You have multiple failing teeth with advanced decay or gum disease that cannot be saved cost-effectively
• You are currently wearing a removable denture and want a permanent fixed alternative
• You have moderate bone loss but still enough ridge height and width for angled implant placement (confirmed by CBCT scan)
• You are in good general health with controlled medical conditions
• You are a non-smoker or willing to stop smoking at least 8 weeks before and after surgery

A CBCT (cone-beam CT) scan taken at your clinic in Ho Chi Minh City gives the treating surgeon precise bone volume measurements. Many patients who were told at home that they need extensive grafting are found to have enough bone for angled All-on-4 placement after a CBCT assessment.

Who is Not a Candidate?

All-on-4 is not appropriate for everyone. The following conditions are contraindications or factors that require specialist evaluation before proceeding:

The clinics listed in this guide conduct a thorough pre-treatment assessment including health history review and CBCT imaging before confirming that All-on-4 is suitable for you.

Bridge Material Options and Cost

The bridge material is the main driver of cost variation within the All-on-4 price range. Three materials are available at Ho Chi Minh City clinics:

Most international patients choose zirconia monolithic for the final bridge due to its superior longevity and appearance. The temporary bridge placed at Visit 1 is always acrylic regardless of what final material is chosen.

Your prosthodontist will discuss which material best suits your bite force, facial aesthetics, and budget during the treatment planning appointment at Visit 1.

Cost Comparison: Ho Chi Minh City vs Other Countries

The table below compares All-on-4 per arch costs across major source markets. These figures are for the implants and final bridge combined and do not include flights and accommodation, which add approximately USD 2,000-3,500 per person for two visits from Australia or New Zealand.

Even accounting for two return flights and accommodation in Ho Chi Minh City, patients from Australia and New Zealand typically save USD 10,000-18,000 per arch compared to having treatment at home. For patients needing both arches, total savings can exceed USD 30,000.

The Two-Visit Protocol Explained

All-on-4 for international patients in Ho Chi Minh City follows a two-visit protocol. This is important to plan for before you commit to treatment. Here is what each visit involves:

Same-Day Teeth: When It Is Possible

All-on-4 includes same-day loading of a temporary bridge as standard. You leave surgery with teeth. This is not the same as leaving with your final permanent bridge, which requires the healing period.

Some patients ask whether they can receive their permanent zirconia bridge in a single visit and skip the second trip. This is possible in limited cases where:

• The patient has sufficient bone density and the CBCT shows excellent implant primary stability
• No extractions are needed in the same session
• The patient is willing to accept an acrylic permanent bridge rather than zirconia (since zirconia fabrication requires laboratory time after osseointegration is confirmed)

Single-visit permanent bridge placement is not recommended for most international patients. A permanent bridge placed before full osseointegration carries a higher risk of failure and repeat surgery. The two-visit protocol is the medically appropriate standard for predictable long-term outcomes.

Your clinician will advise you during treatment planning whether a compressed or single-visit approach is appropriate for your specific case.

Aftercare and Long-Term Hygiene

Proper aftercare protects your implant investment and determines long-term outcomes. Here is the standard protocol:

Well-maintained All-on-4 implants have a reported 10-year survival rate of over 94% in clinical literature. Hygiene compliance is the single most important factor in long-term success.
