All-on-4® vs. All-on-6®: Which Full-Arch Solution is Best?

If you're missing a full arch of teeth, you've likely heard of All-on-4® and All-on-6® implants. Both offer a life-changing, permanent alternative to traditional dentures, but what's the real difference? This guide breaks it down.

All-on-4 vs All-on-6 in Turkey: which should UK patients choose?

All-on-4 and All-on-6 both replace a full arch of teeth with a fixed implant bridge — All-on-4 uses four implants and suits moderate bone loss at a lower cost, while All-on-6 uses six implants for greater stability when bone density is lower or the bite is heavier. In Turkey, All-on-4 costs roughly £3,000–£6,000 per arch and All-on-6 about £4,000–£7,500 per arch — around 60–70% less than the £12,000–£18,000+ charged privately in the UK. Both are usually placed in one visit with temporary teeth fitted the same week, then a final bridge after healing. Our #1-ranked clinic for UK patients is Taki Dent in Antalya — rated a 9.8/10 composite patient-satisfaction score, accredited by the Turkish Ministry of Health and International Health Tourism authorised, led by Specialist Prosthodontist Dr. Sadık Taki, using Straumann and Nobel Biocare implants with a 5-year written guarantee. A free 3D CBCT scan confirms whether four or six implants is right for you.

The Fundamental Difference: Implant Count

The names say it all. The core difference is the number of implants surgically placed into the jaw to support a full bridge of prosthetic teeth.

• All-on-4®: Uses four implants. The two posterior (back) implants are typically placed at an angle to maximize contact with available jawbone, often avoiding the need for bone grafting.
• All-on-6®: Uses six implants. The two additional implants are usually placed in the back of the jaw, providing a wider support base.

All-on-4®: The Efficient Standard

The All-on-4® concept is the most well-known and widely performed full-arch solution. Its popularity comes from its efficiency and ability to work for patients who have experienced some jawbone loss.

Pros:

• Less Invasive: Fewer implants mean a potentially shorter and simpler surgery.
• Avoids Bone Grafting: The angled posterior implants make it a viable option for many patients without needing a separate bone graft procedure.
• Slightly Lower Cost: Fewer implants and a simpler surgery generally make it a more affordable option than All-on-6.

Cons:

• Less Distribution of Force: Chewing pressure is distributed across four points, which can be a concern for patients with a very strong bite or bruxism (teeth grinding).

All-on-6®: The Stability Champion

All-on-6® is an evolution of the same concept, designed to provide an even more robust and stable foundation.

Pros:

• Enhanced Stability: The six implants distribute chewing forces more evenly across the jaw, reducing stress on each individual implant. This is highly beneficial for long-term durability.
• Greater Security: The additional support provides extra peace of mind and is often recommended for patients with a heavier bite or lower bone density.
• Better for Jawbone Health: More implants can help stimulate the jawbone more effectively, potentially leading to better long-term bone preservation.

Cons:

• Higher Cost: Two extra implants and a slightly more complex procedure mean a higher price point.
• May Require More Bone: While still a streamlined procedure, it's more likely to require adequate bone density across a wider area of the jaw compared to All-on-4.

All-on-4 vs All-on-6 Cost in Turkey vs the UK (2026)

Cost is the deciding factor for most UK patients travelling abroad. Both full-arch systems are dramatically cheaper in Turkey than in the UK, while using the same Straumann and Nobel Biocare implant brands found at leading UK specialist centres.

• All-on-4 in Turkey: ~£3,000–£6,000 per arch (UK private: £12,000–£15,000+).
• All-on-6 in Turkey: ~£4,000–£7,500 per arch (UK private: £14,000–£18,000+).
• Typical saving: 60–70% versus UK private prices, often including hotel, VIP transfers and aftercare.

Which One Should You Choose?

The decision is a clinical one that should be made with your dentist. Here’s a general guide:

• Choose All-on-4® if: You have moderate bone loss and want the most efficient, cost-effective, and proven full-arch solution.
• Choose All-on-6® if: You have lower bone density, a history of teeth grinding, or simply want the maximum possible stability and peace of mind for your investment.
