Full-Mouth Dental Implants – All-on-X

For patients who have lost multiple teeth or an entire dental arch, All-on-X full-mouth dental implants are one of the fixed restoration options that may be considered as an alternative to traditional removable dentures.

This article explains what All-on-X is, who it may be suitable for, and what you should know before considering treatment costs.

1. What Is All-on-X?

All-on-X is a dental implant technique that uses a limited number of implants — commonly referred to as All-on-4 or All-on-6 depending on the number of implants — to support a fixed bridge for an entire dental arch.

Instead of placing one dental implant for every missing tooth, the dentist strategically positions the implants in areas where sufficient jawbone is available, then attaches a full-arch fixed bridge supported by the implants.

2. Who Is All-on-X Suitable For?

All-on-X may be considered for patients who:

• Have lost all teeth in one dental arch, either the upper or lower jaw.
• Currently wear removable dentures and want a fixed restoration.
• Have multiple loose or severely damaged teeth that require full-arch extraction.

Whether All-on-X is suitable for you depends on your jawbone condition and overall oral health.

The dentist will assess your condition through an in-person examination and diagnostic imaging before making a treatment recommendation.

3. How Is All-on-X Different from Individual Dental Implants?

Individual dental implants use a separate implant for each missing tooth and may be suitable when only a limited number of teeth are missing or when teeth are missing in different areas.

All-on-X uses fewer implants to support a fixed full-arch bridge and is generally considered for patients who have lost most or all teeth in one dental arch.

The most appropriate option depends on each patient’s individual condition. There is no single treatment approach that is suitable for every case.

Advantages

• Fixed restoration that does not need to be removed like traditional dentures.
• Requires fewer implants than replacing each missing tooth individually.
• May shorten treatment time compared with placing individual implants sequentially, depending on the patient’s condition.

Limitations and Considerations

• Not every patient has sufficient jawbone conditions for immediate treatment.
• Bone grafting may be required before implant placement, which can extend the treatment timeline.
• The full-arch bridge requires proper daily cleaning according to the dentist’s instructions to maintain long-term oral health and treatment outcomes.

4. Implant Systems Recommended for All-on-X at Viet Nga

According to the Viet Nga Dental Price List, the following two implant technology groups are recommended for full-arch All-on-X treatment:

The warranty period and integration time above apply to each individual dental implant. The number of implants required for an All-on-X case will be determined by the dentist based on your specific jawbone condition.

5. The Role of Cone Beam CT in All-on-X Treatment Planning

Before developing an All-on-X treatment plan, the dentist will typically recommend a 3D Cone Beam CT scan to evaluate the density and volume of the jawbone.

The 3D CT images help identify areas with sufficient bone for implant placement and allow the dentist to determine the appropriate number and position of implants before treatment begins.

General Treatment Process

1. Initial examination to assess the teeth and jawbone.
2. 3D Cone Beam CT scan for treatment planning.
3. The dentist recommends the appropriate number of implants and implant system.
4. Dental implant placement.
5. Integration period of approximately 2–4 months, depending on the implant system used.
6. Placement of the fixed full-arch bridge.

6. Bone Grafting for All-on-X

For patients who have been missing teeth for a long time, the jawbone at the implant site may have deteriorated and no longer provide sufficient volume for immediate implant placement.

In such cases, the dentist may recommend bone grafting (3,000,000 VND/site) before or during implant placement. Whether bone grafting is required will be determined through a 3D CT scan and clinical examination.

7. Cost of Full-Mouth All-on-X Dental Implants

The cost of an All-on-X treatment depends on:

• The number of dental implants required, as determined by the dentist.
• The implant system selected (France/Germany or Switzerland).
• The type of full-arch bridge and restoration material.
• Whether bone grafting is required.

Because All-on-X treatment is individually planned for each patient, the dentist will provide a specific quotation after an examination and 3D CT scan.

Aftercare Following Treatment

After the fixed bridge is placed, you should clean the gumline and areas around the dental implants according to your dentist’s instructions and attend regular follow-up appointments to monitor implant integration.

If you experience unusual symptoms such as persistent swelling or pain, or if the bridge becomes loose, contact the dental clinic promptly for an evaluation.

FREQUENTLY ASKED QUESTIONS

1. How many implants are needed for All-on-X?

The number of implants — typically 4–6 implants per dental arch — depends on the patient’s jawbone condition and individual treatment plan. It is not fixed for every case.

2. How is All-on-X different from removable dentures?

All-on-X is a fixed restoration supported by dental implants, while removable dentures are not anchored to implants in the jawbone and can be removed for cleaning.

3. Who may not be suitable for All-on-X?

Patients with insufficient jawbone conditions or certain systemic health conditions that may affect implant treatment require an individual assessment by the dentist before treatment suitability can be determined.

4. How long after All-on-X treatment before I can eat normally?

Recovery time varies depending on each patient’s condition and healing process. During your consultation at Viet Nga Dental Clinic, the dentist will provide specific guidance based on your treatment plan.
