What is the difference between All-on-4 and All-on-6?

All-on-4 uses 4 implants per arch to support a full set of teeth — 2 straight at the front and 2 tilted at 30–45° at the back. All-on-6 uses 6 implants (4 straight + 2 tilted, or all straight in a wider arch distribution), providing greater surface area and load distribution. All-on-6 is stronger and better suited for patients with heavier bite forces or who want a 28-tooth bridge rather than 12-tooth.

How much does All-on-4 cost in Turkey vs All-on-6?

At Taki Dent Antalya using Nobel Biocare implants: All-on-4 costs £5,500–£7,000 per arch; All-on-6 costs £7,000–£9,000 per arch. Both arches (All-on-4 x2) costs approximately £11,000–£14,000; both arches All-on-6 costs £14,000–£18,000. UK private equivalent: £15,000–£20,000 per arch for All-on-4; £18,000–£25,000 per arch for All-on-6.

Who is a candidate for All-on-6 vs All-on-4 in Turkey?

All-on-4 is suitable for most edentulous (toothless) or near-edentulous patients. All-on-6 is recommended for: patients with heavy bite forces or bruxism, patients who want a fuller 28-tooth bridge (rather than 12-tooth), patients with sufficient posterior bone height to place 6 implants without tilting, and patients seeking maximum implant stability for psychological reassurance.

All-on-4 vs All-on-6 in Turkey: Which Is Right for You?

All-on-4 and All-on-6 are the two most common full-arch implant solutions for patients who have lost most or all of their teeth. Both replace an entire arch with a fixed, non-removable bridge — but the number of implants, the bridge design, and the clinical indications differ meaningfully. This guide explains exactly what each option involves and which is right for you.

What Is All-on-4?

All-on-4 was developed by Dr. Paulo Maló in collaboration with Nobel Biocare in the late 1990s and early 2000s. The concept is elegant: use 4 implants per arch (2 placed straight at the anterior, 2 placed at a 30–45° angle posteriorly) to support a full-arch fixed bridge — all in a single surgery, with immediate loading (teeth the same day).

The tilted posterior implants are the key innovation. By angling the rear implants, surgeons can avoid the maxillary sinus (upper jaw) and the inferior alveolar nerve (lower jaw) — dramatically reducing the need for bone grafting. This makes All-on-4 viable for many patients with significant bone loss who would otherwise need extensive pre-implant grafting procedures.

The standard All-on-4 bridge is a 12-tooth prosthesis (supporting the aesthetically and functionally important teeth visible when smiling and eating).

What Is All-on-6?

All-on-6 follows the same principle — full-arch rehabilitation with implant-supported bridge — but uses 6 implants rather than 4. The additional implants provide:

Greater load distribution: Force from biting and chewing is spread across 6 contact points rather than 4
Redundancy: If one implant fails to integrate (rare), the remaining 5 can still support the prosthesis
Compatibility with larger bridges: All-on-6 is frequently used with a 28-tooth zirconia bridge (full arch), not just 12 teeth
Reduced stress per implant: Each implant carries less force, potentially extending long-term prosthesis longevity

All-on-6 typically requires better bone quantity (or bone grafting) since placing 6 implants provides less flexibility to work around anatomical constraints than the tilted All-on-4 configuration.

All-on-4 vs All-on-6: Direct Comparison

Feature	All-on-4	All-on-6
Implants per arch	4	6
Teeth in bridge	12 (standard)	12–28 (full arch possible)
Bone grafting needed?	Rarely — tilted implants avoid anatomy	Sometimes — depends on bone volume
Same-day teeth?	Yes	Yes
Bite strength capacity	Good	Excellent
Antalya cost (per arch)	£5,500–£7,000	£7,000–£9,000
UK cost (per arch)	£15,000–£20,000	£18,000–£25,000
Treatment complexity	Standard	Moderate
Best for	Most patients, bone-loss patients	Heavy biters, bruxism, full 28-tooth bridge

Which Should You Choose?

Choose All-on-4 if:

You have significant bone loss and want to avoid bone grafting
You want the most cost-effective full-arch solution
You have a normal bite force (no confirmed bruxism)
A 12-tooth aesthetic bridge meets your needs

Choose All-on-6 if:

You have confirmed bruxism (teeth grinding) or a very strong bite
You want a full 28-tooth zirconia bridge (all teeth, not just the visible 12)
You have sufficient bone volume in the posterior regions
You want maximum redundancy and load distribution
You are willing to invest an additional £1,500–£2,000 per arch for the upgrade

The Full-Arch Process at Taki Dent, Antalya

At Taki Dent, full-arch rehabilitation (All-on-4 or All-on-6) follows a two-trip protocol:

Trip 1 (5–7 days in Antalya)

CBCT 3D scan and digital treatment planning
Extraction of any remaining failing teeth
Implant placement surgery (Nobel Biocare Active or Parallel CC)
Immediate loading: temporary acrylic bridge fitted same day
Return to UK with functional temporary teeth

Osseointegration at Home (3–6 months)

Implants fuse with jawbone. Normal eating with temporary bridge. Remote monitoring via WhatsApp.

Trip 2 (3–4 days in Antalya)

CBCT scan to confirm osseointegration
Digital impressions for permanent zirconia bridge
In-house CAD/CAM laboratory fabrication (24–48 hours)
Permanent zirconia bridge fitted — fly home

Conclusion

All-on-4 is the right choice for the majority of full-arch patients — it handles most clinical situations elegantly, avoids bone grafting, and delivers outstanding aesthetic and functional results. All-on-6 is the upgrade for patients with very high bite demands or who want the full 28-tooth bridge. Both are available at Taki Dent using Nobel Biocare implants at 70–80% below UK costs.
