5 Reasons All-on-4 Is Changing Lives for Edentulous Patients in Vietnam

For patients who have lost all or most of their teeth — whether through decay, gum disease, injury, or years of wearing ill-fitting dentures — the options have historically been limited to conventional removable dentures or an expensive and time-consuming sequence of individual implants. All-on-4 changed that equation permanently when Nobel Biocare validated the protocol in the late 1990s. Since then, it has transformed the lives of millions of edentulous patients worldwide who now have fixed teeth where removable appliances once caused daily frustration.

Vietnam has emerged as one of the most popular destinations for All-on-4 treatment among international patients, particularly from Australia, the United Kingdom, and New Zealand — countries where the cost of full-arch implant rehabilitation is prohibitive for most patients without access to health insurance that covers major dental work. At Picasso Dental Clinic in Hanoi, the All-on-4 team performs this procedure regularly for patients who arrive toothless or nearly toothless and leave with a complete, fixed, functional smile.

These five reasons explain why All-on-4 has the power to fundamentally change the daily life of an edentulous patient — and why so many are choosing to have it done in Vietnam.

Reason 1: Fixed Teeth on the Same Day as Surgery

The most immediate transformation All-on-4 delivers is a set of fixed teeth on the day of surgery — not a temporary denture, not a gap, but a full bridge that is screwed to the implants and cannot be removed by the patient. This is the single most impactful difference between All-on-4 and all previous options for edentulous patients.

Conventional dentures are removed nightly, stored in water, and must be cleaned separately from normal oral hygiene routines. They move during eating and speaking. They require adhesives. As the jawbone continues to resorb without tooth roots stimulating it, the denture becomes progressively looser until it is nearly useless without significant adhesive application.

On the morning of All-on-4 surgery, the patient arrives — often having worn a denture for years — and by the afternoon they leave with a fixed bridge. They eat in the clinic’s recovery area before going home. They speak without clicking or shifting. They go to sleep without removing anything. For most All-on-4 patients, this single day represents the most significant change in their quality of life in years, sometimes decades.

The temporary bridge placed on surgery day is made from an acrylic material designed for the osseointegration healing period. It is fully functional for eating soft to medium-consistency foods and looks presentable enough that most patients comfortably socialise throughout the healing phase. After 3 to 6 months, when the implants are confirmed to have fully integrated with the bone, the permanent prosthesis — typically a more durable zirconia bridge — is fabricated and fitted.

Reason 2: No Bone Grafting Required for Most Patients

One of the barriers that historically prevented many edentulous patients from accessing dental implants was bone volume. After teeth are lost and dentures are worn for years, the jawbone resorbs progressively — losing height and width as it no longer receives the mechanical stimulation of tooth roots. Patients who present for implant consultations a decade after losing their teeth often have significantly reduced bone volume, leading to assessments that they “don’t have enough bone” for implants.

The All-on-4 protocol was specifically engineered to overcome this limitation. By angling the two posterior implants at 30 to 45 degrees, the surgical team can access bone that remains higher in the jaw — away from the areas of maximum resorption at the back of the arch. In the lower jaw, this angulation avoids the inferior alveolar nerve. In the upper jaw, it avoids the maxillary sinuses. In both cases, it allows four implants to be placed with sufficient anchorage for immediate loading, even in jaws where traditional implant placement would require extensive bone grafting.

For many patients, this means the difference between a treatment plan that includes a bone graft procedure requiring 6 to 9 additional months of healing — and dramatically higher cost — and a treatment plan that can be completed in a single surgical day. A CBCT scan at Picasso Dental Clinic before your All-on-4 consultation will confirm whether your jaw anatomy allows for bone-graft-free All-on-4 placement.

Reason 3: Eating Without Restriction Returns

Patients who wear conventional complete dentures commonly describe a progressive narrowing of their diet. Apples are cut into small pieces or avoided. Corn on the cob is off the table. Steak requires significant effort and concentration. Crusty bread is managed cautiously. Any food that requires biting into with incisors — the front teeth — is potentially destabilising to a lower denture. Social meals become a source of anxiety rather than pleasure.

The bite force transmitted through an implant-supported fixed bridge is categorically different from that of a removable denture. Implants anchor into the jawbone and transmit bite forces directly to the bone, in the same way that natural tooth roots do. The mechanical stability of four implants supporting a full arch allows patients to eat an unrestricted diet — not carefully managed, not strategically selected, but genuinely unrestricted within reasonable common sense for any prosthetic restoration.

All-on-4 patients at Picasso Dental Clinic consistently report that the ability to eat normally is the most frequently mentioned quality-of-life improvement, above even the aesthetic changes. The patient who arrives unable to eat a full meal without discomfort or embarrassment and who leaves able to order anything on a restaurant menu experiences a functional restoration that extends to nutrition, social confidence, and general wellbeing.

During the healing phase with the temporary bridge, patients are advised to avoid very hard foods — hard nuts, ice, raw carrots — to protect the implants while osseointegration completes. Once the final prosthesis is fitted, dietary restrictions are largely lifted.

Reason 4: The Jawbone Stops Shrinking

The least visible but clinically most important benefit of All-on-4 is what it does to the jawbone. Dental implants are the only tooth replacement option that replicates the mechanical function of a tooth root — transmitting bite forces into the bone during normal use. This stimulation is what signals the body to maintain bone density and volume in the jaw.

Without this stimulation — as occurs with conventional dentures resting on the gum surface — the jawbone continues to resorb. Over a decade, a patient who has worn conventional dentures can lose 40 to 60% of their original bone volume. This bone loss changes the shape of the face: the lower third collapses inward, the chin rotates toward the nose, the cheeks appear hollow, and the facial profile develops the classic features of long-term edentulism — changes often described as appearing much older than actual age.

All-on-4 implants placed in the jawbone halt this process. The four titanium posts transmit mechanical load into the surrounding bone at each implant site, preserving bone density at those locations and dramatically slowing the resorption process across the arch. Patients who have All-on-4 placed after years of denture wear often notice that their facial profile is supported in a way it has not been since their natural teeth were lost.

This benefit compounds over time. A patient with All-on-4 at age 60 will have significantly more bone preserved at 70 than a patient who continued wearing conventional dentures for the same decade. That preserved bone has clinical value: if prosthetic work is ever needed in the future, there is a jaw to work with.

Reason 5: The Cost in Vietnam Makes It Accessible

In Australia, a full-arch All-on-4 procedure — including the four implants, abutments, and the final prosthetic bridge — typically costs $25,000 to $40,000 AUD per arch. For a patient needing both upper and lower arches restored, the total bill can reach $50,000 to $80,000 AUD. Private health insurance in Australia covers a small fraction of this through major dental extras, and the Medicare system does not cover dental treatment at all. The result: most edentulous patients in Australia who cannot access this treatment simply continue wearing conventional dentures, with all the limitations that entails.

At Picasso Dental Clinic in Hanoi, All-on-4 is priced at $8,000 to $12,000 USD per arch depending on the implant system (Osstem, Dentium, Straumann, or Nobel Biocare) and any additional procedures required. After adding return flights from Sydney ($600 to $900 AUD), a 10 to 14 day stay in Hanoi ($800 to $1,400 AUD for accommodation), and all ancillary costs, the total trip expenditure for one arch is typically $12,000 to $18,000 AUD — a saving of $10,000 to $25,000 AUD compared to Australian pricing for the same procedure.

For patients needing both arches, the savings are proportionally larger. Patients who have been told they cannot afford All-on-4 at home routinely discover that the total cost of treatment in Vietnam — including everything — falls within a budget they can manage, often without financing.

All-on-4 at Picasso Dental Clinic, Hanoi

The All-on-4 team at Picasso Dental Clinic uses Nobel Biocare, Straumann, and Osstem implant systems depending on the patient’s clinical needs and budget. The surgical planning begins with a CBCT scan that allows the implantologist to plan exact implant positions in three dimensions before the procedure begins, reducing surgical time and improving accuracy.

International patients can send existing panoramic X-rays or CBCT scans for a remote assessment before booking travel. The patient coordinator team works with each patient to build a treatment schedule around their planned stay, ensuring the surgical day, any required extractions, and post-operative check appointments are sequenced efficiently within the visit.
