All-on-4 vs All-on-6 Dental Implants: Which Is Better?

If you are considering full-arch tooth replacement, you have probably encountered two popular options: All-on-4 and All-on-6 dental implants. Both treatments offer permanent solutions for missing teeth, but they differ in implant count, stability, bone requirements, and cost. Understanding which option suits your unique situation can help you make a confident decision about restoring your smile.

At TruSmile Now, Dr. Wremaine Wilson, DDS, brings a passion for transformative dental care to every implant case. With training in general, cosmetic, and implant dentistry, Dr. Wilson focuses on helping patients regain full function and confidence through permanent tooth replacement solutions.

The choice between All-on-4 All-on-6 implants depends on several factors including your bone density, budget, lifestyle needs, and long-term goals. This guide breaks down everything you need to know about both options so you can have an informed conversation with your dentist.

🦷 WHAT ARE ALL-ON-4 ALL-ON-6 IMPLANTS?

Both All-on-4 All-on-6 implants are full-arch restoration techniques that replace an entire upper or lower set of teeth using strategically placed titanium posts. These posts fuse with your jawbone through a process called osseointegration, creating a stable foundation for a custom prosthetic arch.

All-on-4 uses four implants per arch, typically placed at specific angles to maximize contact with existing bone. The posterior (back) implants are angled at up to 45 degrees, which allows them to avoid areas with insufficient bone and provides immediate stability.

All-on-6 uses six implants per arch, providing two additional support points. These extra implants are usually placed vertically in the front and mid-arch regions, creating a broader distribution of chewing forces across the jawbone.

According to peer-reviewed research on implant survival rates, both techniques demonstrate excellent long-term success when performed by experienced clinicians. The American Dental Association recognizes these procedures as effective solutions for edentulous patients seeking fixed prosthetic rehabilitation.

⚖️ KEY DIFFERENCES BETWEEN ALL-ON-4 ALL-ON-6 IMPLANTS

Understanding the distinctions between All-on-4 All-on-6 implants helps you evaluate which approach aligns with your oral health status and personal preferences.

Number of Implants and Placement

The most obvious difference is the implant count. All-on-4 uses four strategically angled implants, while All-on-6 adds two more for enhanced support. The additional implants in the All-on-6 system create more contact points with your jawbone, which can improve load distribution during chewing and biting.

Bone Density Requirements

All-on-4 was specifically designed for patients with moderate to severe bone loss. The angled posterior implants engage denser bone in the front of the jaw, often eliminating the need for bone grafting. All-on-6 typically requires slightly better bone quality and volume since it uses more vertical implant placements that need adequate bone height and width.

Stability and Force Distribution

With six implants instead of four, All-on-6 distributes chewing forces across more support points. This can reduce stress on individual implants and may offer enhanced stability for patients with strong bite forces or those who prefer particularly hard or chewy foods. However, properly executed All-on-4 also provides excellent stability for most patients.

Cost Considerations

Because All-on-6 requires two additional implants, the procedure typically costs more than All-on-4. At TruSmile Now, All-on-4/6 with PMMA starts at $9,999 and All-on-4/6 with Zirconia starts at $13,999. The exact price depends on your specific case, material choice, and whether any preparatory procedures are needed.

We offer flexible payment plans through Cherry to make treatment affordable, regardless of which option you choose.

Treatment Timeline

Both procedures can often be completed with same-day temporary teeth. The surgical time for All-on-6 may be slightly longer due to the additional implant placements, but many patients receive their provisional prosthesis on the same day as surgery. Final restoration typically occurs after 3-6 months of healing.

✅ WHICH OPTION IS BETTER FOR YOU?

There is no universal answer to whether All-on-4 All-on-6 implants are superior. The best choice depends on your individual circumstances.

All-on-4 May Be Better If:

You have significant bone loss and want to avoid bone grafting procedures. The angled implant technique works well even with reduced bone volume, making it an excellent option for patients who have worn dentures for years or experienced extensive bone resorption.

Budget is a primary concern. With fewer implants required, All-on-4 typically costs less upfront while still delivering permanent, functional results.

You want a proven, time-tested solution. All-on-4 has decades of clinical research supporting its effectiveness and has helped millions of patients worldwide regain their smiles.

All-on-6 May Be Better If:

You have adequate bone density and want maximum stability. The additional implants provide extra support that some patients find reassuring, particularly those with strong bite forces.

You want enhanced redundancy. If one implant develops issues over time, the remaining five implants in an All-on-6 system can continue supporting your prosthesis more easily than the remaining three in an All-on-4 configuration.

Your dentist recommends it based on your anatomy. Some jaw shapes and bone patterns are better suited to six-implant placement, and your dentist can identify this during your 3D imaging evaluation.

📊 SUCCESS RATES AND LONG-TERM OUTCOMES

Both All-on-4 All-on-6 implants demonstrate excellent success rates when placed by experienced surgeons. Clinical studies show survival rates above 95% at five years for both techniques when patients follow proper maintenance protocols.

The additional implants in All-on-6 may offer slightly better outcomes in specific situations, particularly for patients with parafunctional habits like teeth grinding. However, the difference in success rates between the two approaches is minimal when case selection is appropriate.

Long-term maintenance is similar for both options. You will need regular professional cleanings, daily home care with specialized tools, and periodic checkups to ensure your implants remain healthy. At TruSmile Now, we provide comprehensive aftercare instructions and ongoing support to maximize the longevity of your restoration.

🔬 HOW THE PROCEDURE WORKS

Whether you choose All-on-4 or All-on-6, the treatment process follows similar steps. Understanding what to expect can help reduce anxiety and prepare you for your transformation.

Step 1: Comprehensive Evaluation

Your journey begins with a thorough examination including a free 3D Cone Beam CT scan at TruSmile Now. This advanced imaging allows Dr. Wilson to assess your bone quality, sinus position, nerve location, and overall anatomy to determine which approach suits you best.

Step 2: Treatment Planning

Using digital planning software, your surgical team maps out the precise position, angle, and depth of each implant. This virtual planning ensures optimal placement and allows fabrication of your provisional prosthesis before surgery day.

Step 3: Implant Surgery

On surgery day, any remaining teeth are removed if necessary, and the implants are placed according to the digital plan. Most patients receive IV sedation for comfort. The procedure typically takes 2-3 hours per arch.

Step 4: Immediate Provisional Teeth

In most cases, you will leave with a temporary prosthesis attached to your new implants the same day. These provisional teeth allow you to eat soft foods and smile confidently while your implants heal.

Step 5: Final Restoration

After 3-6 months of healing, your permanent prosthesis is fabricated in our state-of-the-art in-house dental lab. This final restoration is custom-designed for optimal aesthetics, function, and durability. You can choose between PMMA (a high-quality acrylic) or zirconia (a premium ceramic material).

💰 COST COMPARISON AND FINANCING

Cost is often a deciding factor when comparing treatment options. While All-on-6 typically costs more due to the additional implants, the price difference may be less significant than you expect.

At TruSmile Now, transparent pricing helps you plan your investment with confidence:

• All-on-4/6 with PMMA: Starting at $9,999 (1 Year Warranty)
• All-on-4/6 with Zirconia: Starting at $13,999
• New Patient Special: $49 (includes exam, X-rays, and consultation)

Many patients qualify for insurance coverage, particularly if tooth loss affects your ability to eat or speak properly. We accept most major insurance plans including Delta Dental, Cigna, UnitedHealthcare, MetLife, Aetna, and Blue Cross Blue Shield. We also accept Medicare Part B for medically necessary treatments.

For out-of-pocket expenses, we offer flexible payment plans through Cherry with low monthly payments that fit most budgets.

❓ FREQUENTLY ASKED QUESTIONS

Is All-on-6 stronger than All-on-4?

All-on-6 distributes chewing forces across six implants instead of four, which can provide additional stability and redundancy. However, properly placed All-on-4 All-on-6 implants both offer excellent strength for normal eating and function. The best choice depends on your bone quality and individual needs.

Can I get All-on-6 if I have bone loss?

All-on-6 typically requires better bone quality than All-on-4 since it uses more vertical implant placements. If you have significant bone loss, All-on-4 may be recommended, or bone grafting might be suggested before All-on-6 placement. A 3D CT scan during your consultation will determine which option suits your anatomy.

How much more does All-on-6 cost compared to All-on-4?

The cost difference varies by practice and case complexity, but All-on-6 typically costs a few thousand dollars more due to the additional implants. At TruSmile Now, both procedures start at similar base prices, with final cost determined by your specific needs and chosen materials. We provide detailed cost breakdowns during your free consultation.

Does All-on-6 last longer than All-on-4?

Both treatment options can last 20+ years with proper care. The longevity depends more on factors like oral hygiene, regular dental visits, bone quality, and overall health rather than the number of implants. Clinical studies show comparable long-term success rates for both approaches when performed correctly.

Can I switch from All-on-4 to All-on-6 later?

In some cases, additional implants can be added to an existing All-on-4 restoration if needed, though this requires adequate bone and careful planning. However, most patients find that their initial choice serves them well for life. Discussing your long-term goals during initial planning helps ensure you select the right option from the start.

Which option is better for someone with diabetes?

Both options can work well for patients with controlled diabetes. Some dentists prefer All-on-6 for diabetic patients because the additional implants provide extra support if healing is slower. However, the most important factor is maintaining good blood sugar control before and after surgery. Your medical history will be carefully reviewed during your consultation.
