All-on-4 and All-on-6 dental implants are two of the most effective full-arch restoration options for people who have lost multiple teeth. This guide explains the differences, benefits, costs, ideal candidates, and why Worldwide Dental Hospital is a trusted destination for full-mouth implant treatment in Vietnam.

Understanding Full-Arch Implant Solutions
Why Full-Arch Implants Are Growing in Popularity
Many patients who suffer from complete tooth loss or severe dental problems look for a permanent solution that restores both function and aesthetics. Traditional dentures are affordable, but they are often unstable, uncomfortable, and less natural in appearance. Full-arch implant systems, such as All-on-4 and All-on-6, provide a fixed, long-lasting alternative that feels remarkably close to natural teeth.
What Are Full-Arch Implant Bridges?
Instead of replacing each missing tooth individually, full-arch implant systems support an entire row of teeth using just 4 or 6 strategically placed implants. This approach allows patients to chew better, smile confidently, and maintain healthy bone structure without the discomfort of removable dentures.
What Is the All-on-4 Implant System?
How All-on-4 Works
The All-on-4 concept uses four implants placed in specific angles to support a full arch of replacement teeth. Two implants are placed vertically at the front of the jaw, and two are inserted at an angle at the back to maximize bone contact.
Advantages of All-on-4
- Fewer Implants Required
Only four implants are needed, making the procedure less invasive and reducing overall cost. - Suitable for Patients With Low Bone Density
The angled back implants often reduce the need for bone grafting. - Faster Treatment
Many patients can receive a temporary fixed bridge within 24–72 hours. - More Affordable
Since it uses fewer implants, the All-on-4 system typically costs less than All-on-6.
Limitations of All-on-4
- Less Support Compared to All-on-6
With only four implants, the distribution of chewing force is more limited. - Not Ideal for Severe Bite Forces
Patients with strong clenching or grinding habits may need more implants for stability. - Less Suitable for Severe Bone Loss
Although angled implants help, patients with extreme bone resorption may still require additional procedures.

What Is the All-on-6 Implant System?
How All-on-6 Works
The All-on-6 solution uses six implants placed across the jawbone. This increases stability, distributes bite pressure more evenly, and provides a stronger foundation for the final bridge.
Advantages of All-on-6
- Greater Stability and Strength
Six implants offer more balanced support, especially for long-span bridges. - Better Long-Term Durability
More implants mean better load distribution, reducing the risk of implant overload. - Ideal for Patients With Adequate Bone Density
Patients with healthy bone levels benefit from increased implant contact and improved function. - Higher Chewing Efficiency
The additional implants allow for stronger bite force and better chewing performance.
Limitations of All-on-6
- Higher Cost
More implants result in a higher total treatment fee. - May Require Bone Grafting
Patients with insufficient bone may need sinus lift or grafting before placing additional implants. - Slightly Longer Surgical Time
Placing six implants requires more precision and time compared to four.

Key Differences Between All-on-4 and All-on-6
Number of Implants
- All-on-4: Four implants
- All-on-6: Six implants
The additional implants in All-on-6 provide enhanced stability.
Stability and Load Distribution
All-on-6 distributes the biting force more evenly across the jaw, reducing the risk of overload and complications.
Bone Requirements
All-on-4 is often recommended for patients with reduced bone density because the angled implants compensate for bone loss. All-on-6 requires more bone support.
Longevity
While both systems can last decades, All-on-6 generally provides greater long-term predictability thanks to better load sharing.
Treatment Cost
All-on-6 is more expensive due to the additional implants and potential need for grafting.
Which Treatment Is Right for You?
All-on-4 May Be Best If You:
- Have moderate bone loss
- Want to avoid bone grafting
- Prefer a lower-cost full-arch solution
- Need a faster treatment timeline
- Are looking for a minimally invasive option
All-on-6 May Be Best If You:
- Want maximum stability and longevity
- Have sufficient bone volume
- Want the highest level of chewing function
- Prefer a more durable and robust structure
- Want better long-term implant distribution
Worldwide Dental Hospital provides full diagnostic evaluations—including CBCT imaging—to determine the safest and most predictable option for each patient.

Step-by-Step Procedure for Both All-on-4 and All-on-6
Step 1: Consultation and Diagnostic Imaging
- Full oral examination
- CBCT scan to assess bone structure
- Bite evaluation and digital treatment simulation
- Discussion of options and expected outcomes
Step 2: Treatment Planning
The dental team creates a detailed plan that includes implant positions, bone support, and prosthetic design. Digital planning reduces surgical risk and improves accuracy.
Step 3: Implant Placement Surgery
- Local anesthesia or sedation
- Removal of damaged teeth (if needed)
- Placement of 4 or 6 implants
- Immediate placement of a temporary bridge (when applicable)
Step 4: Osseointegration
Implants fuse with the bone over 3–6 months. Patients receive instructions on dietary care, oral hygiene, and follow-up visits.
Step 5: Final Prosthetic Placement
After healing, the final bridge is designed using premium materials such as zirconia or hybrid ceramic for maximum strength and aesthetics.
