All-on-4 vs All-on-6: Which Full-Mouth Implant Solution Is Right for You?

When your remaining teeth are failing or already lost, full-mouth dental implants are the modern answer. Two protocols dominate the conversation: All-on-4 and All-on-6. Both restore a full arch on the same day. Both avoid removable dentures. Both can transform your quality of life.

They are not the same treatment, though. Choosing between them is a clinical decision based on your bone quality, your bite force, your medical history and your budget. This guide explains the real differences, the price in Turkey in 2026, and the specific factors that push a case one way or the other.

What Is All-on-4?

All-on-4 is a protocol developed by Dr. Paulo Malo in Portugal in the late 1990s. The concept is elegant: instead of placing one implant per tooth, four strategically positioned implants support an entire fixed bridge of 10 to 14 teeth.

The trick is that the two posterior implants are tilted up to 45 degrees, which does three things:

• Avoids major anatomical structures (the sinus in the upper jaw, the inferior alveolar nerve in the lower jaw)
• Uses the densest remaining bone
• Eliminates the need for bone grafting in most cases

This makes All-on-4 the go-to solution for patients with significant bone loss who do not want to wait 6 to 12 months for grafting.

What Is All-on-6?

All-on-6 follows the same philosophy but adds two more implants, usually one on each side in the premolar region. Instead of four, you have six support points.

The extra implants provide:

• Better load distribution across the arch
• Lower peri-implant stress per implant
• Shorter cantilever (the unsupported section of the bridge at the back)
• Better survival rate in patients with heavy bite force

All-on-6 requires more bone volume, so it is typically reserved for patients whose anatomy allows it or who have done prior bone grafting.

Head-to-Head: Key Differences

Factor	All-on-4	All-on-6
Implants per arch	4	6
Bone requirement	Low (angled implants avoid grafting)	Moderate to high
Surgical time	2 to 3 hours per arch	3 to 4 hours per arch
Immediate load (temporary bridge same day)	Yes	Yes
Final bridge timing	3 to 4 months later	3 to 4 months later
Survival rate at 10 years	92 to 96 percent (published studies)	95 to 98 percent (published studies)
Best for	Moderate to severe bone loss, lower budget	Strong bite force, preserved bone, long-term priority
Price in Antalya (per arch, 2026)	3.800 to 5.500 EUR	4.500 to 6.800 EUR
Price in UK (per arch)	12.000 to 16.000 GBP	14.000 to 18.000 GBP
Price in Germany (per arch)	14.000 to 18.000 EUR	16.000 to 22.000 EUR

When All-on-4 Is the Right Answer

Choose All-on-4 when one or more of these apply:

• You have moderate to severe bone loss and you do not want grafting
• You want the lowest full-arch option without compromising long-term survival
• Your bite force is average (you do not grind your teeth aggressively)
• You want a same-day fixed solution to walk out with teeth on the day of surgery

Modern All-on-4 with angled implants and zirconia bridges is an evidence-based, well-documented protocol with over 20 years of follow-up data. It is not a compromise treatment. For the right case, it is clinically optimal.

When All-on-6 Is the Right Answer

Choose All-on-6 when:

• You have good bone volume or have completed prior grafting
• Your bite is heavy (bruxism, strong chewing pattern)
• You want the longest possible bridge lifespan
• You prefer redundancy: if one implant ever fails, five remain instead of three
• Cost is not the driving factor

All-on-6 distributes bite forces more evenly, which reduces long-term peri-implant bone stress. If your anatomy supports it and your budget allows it, All-on-6 is a slightly more conservative long-term play.

What About All-on-8?

Some clinics offer All-on-8. Clinically, going above 6 implants per arch rarely adds meaningful benefit for a fixed bridge. The additional surgical trauma is not justified by measurable improvement in survival or function. Be cautious of clinics that default to 8 implants per arch without a specific anatomic reason: it adds cost without adding outcome.

The Real-World Treatment Journey in Antalya

Whichever protocol you choose, the treatment looks like this in Antalya:

First trip (7 to 10 days):

• Day 1: Arrival, CBCT, treatment planning
• Day 2 to 3: Extractions if needed, implant placement (both arches if applicable), immediate temporary bridge placed
• Day 4 to 7: Rest, healing checks, minor adjustments to the temporary bridge
• Day 8 to 10: Final check, fly home

Home healing period: 3 to 4 months. Osseointegration happens in your jaw. You eat with the temporary bridge (soft diet for the first 4 to 6 weeks, then normal food).

Second trip (5 to 7 days):

• Day 1: Arrival, check of osseointegration, final impressions (digital scan)
• Day 2 to 4: Lab fabrication of final zirconia bridge
• Day 5: Try-in, bite adjustment
• Day 6 to 7: Final bridge placement, post-op check, fly home

Which Bridge Material Should You Choose?

Once the implants integrate, the bridge that sits on top is typically one of three materials:

• Acrylic over titanium bar. Cheapest. Prone to staining and chipping. We do not recommend it as a permanent solution.
• Zirconia monolithic bridge. Current gold standard. Extremely strong, stain-resistant, aesthetic with modern multilayer zirconia. Most serious Antalya clinics default to this for the final bridge.
• Porcelain fused to metal. Older technology, still used in some clinics. Metal can show through the gums over time. Generally replaced by zirconia in modern practices.

Ask your clinic which material is included in the quote. Zirconia final bridges add around 500 to 1.200 EUR per arch compared to acrylic but triple the lifespan.

How Much Does the Whole Thing Really Cost?

For a full upper and lower reconstruction in Antalya in 2026 with premium implant brands and zirconia final bridges:

• All-on-4 upper and lower: 7.500 to 11.000 EUR (total)
• All-on-6 upper and lower: 9.000 to 13.500 EUR (total)

These totals usually include:

• CBCT and treatment planning
• All extractions
• 4 or 6 implants per arch (premium brand, named on quote)
• Immediate temporary bridges
• Final zirconia bridges
• Hotel for both trips
• Airport transfers for both trips
• Coordinator and translator
• Lifetime warranty on implants, 10 years on the bridge

Compare this to 24.000 to 36.000 GBP in the UK or 28.000 to 45.000 EUR in Germany for equivalent work and the case for Antalya becomes very clear, provided you pick a serious clinic.

How to Choose Between All-on-4 and All-on-6 in Practice

You do not have to decide alone. A proper remote assessment decides this for you:

1. Send your panoramic x-ray or, ideally, a CBCT scan if you have one
2. The partner specialist reviews bone height, bone density and sinus pneumatisation
3. You receive a recommendation in writing with the specific reason for All-on-4 or All-on-6
4. If the case is borderline, you see both treatment plans with prices and make the choice yourself

At Manhetra we always send you both options if the case is borderline. We never push you into the more expensive protocol without a clinical reason.

Frequently Asked Questions

Will I have teeth the day of surgery?

Yes. Both All-on-4 and All-on-6 use immediate loading: a temporary acrylic bridge is screwed onto the implants the same day. You fly home with fixed teeth, not removable dentures.

Can I eat normally during the healing period?

Soft diet for 4 to 6 weeks (pasta, fish, eggs, soft vegetables). Then gradually return to normal food with the temporary bridge. Avoid chewing ice or biting into hard crusts until the final bridge is placed.

What if one implant fails during healing?

Implant failure rates for All-on-4 and All-on-6 are around 2 to 5 percent at 10 years. If one fails early, it is usually replaced during the second trip at no cost if within warranty. The bridge still functions on the remaining implants in the short term thanks to the multi-implant design.

Are All-on-4 and All-on-6 reversible?

The implants themselves are considered permanent once integrated, so the treatment is not reversible in the same way as removable dentures. This is why the initial planning is so important.

Do I need to avoid smoking?

Strongly recommended. Smoking significantly increases the risk of implant failure and peri-implantitis. Stop at least 2 weeks before surgery and ideally do not resume.

What about diabetics?

Well-controlled Type 2 diabetes is not a contraindication, but HbA1c should be below 7 percent before surgery. Your medical history is reviewed in detail before the treatment plan is finalised.

How do I find out which option is right for me?

Send us a panoramic x-ray or any recent dental imaging you have on WhatsApp. Our partner specialists review it and send back a specific recommendation (All-on-4 or All-on-6, one arch or both) with reasoning, within 24 to 48 hours.
