All-on-4 vs All-on-6 Dental Implants: Which Is Right for You?

All-on-4 vs All-on-6 Dental Implants: A Complete Comparison

Four implants versus six implants. Both give you a full set of fixed teeth, but the engineering is different.

All-on-4 uses four dental implants to support a full arch of replacement teeth, while All-on-6 uses six implants for the same job. All-on-6 spreads bite force across more anchor points and works best when you have good bone density. All-on-4 was designed for people with less bone — it uses angled back implants to grab onto whatever bone you have left.

Your bone density matters most. But budget, jaw size, and whether you grind your teeth all play a role.

What Each Procedure Involves

All-on-4

Two straight implants go in the front. Two angled implants (usually 30-45 degrees) go in the back.

The angled placement is the clever bit. It reaches denser bone toward the front of your jaw, dodging the need for bone grafting in most cases. A full arch of 10-12 teeth attaches to these four implants, either the same day or after healing.

All-on-6

Six implants spread across your jaw: two front, two middle, two back. More anchor points mean more stability and stronger bite force.

The force from chewing gets distributed across six points instead of four. Less stress on each implant. Same full arch attached, but with better support underneath.

Side-by-Side Comparison

Factor	All-on-4	All-on-6
Number of implants per arch	4	6
Bone density required	Lower (angled implants compensate)	Higher (vertical placement standard)
Bone grafting typically needed	Rarely	Sometimes
Procedure time	2-3 hours per arch	3-4 hours per arch
Bite force distribution	Concentrated on 4 points	Spread across 6 points
Long-term durability	Excellent (15-25 years)	Excellent (20-30 years)
Suitability for full arch	Yes	Yes
Immediate loading possible	Yes (same-day teeth)	Yes (same-day teeth)
Recovery time	3-6 months full integration	3-6 months full integration
Implant failure impact	Loss of 1 implant is more critical	Greater redundancy if 1 implant fails

Cost Comparison

The price difference reflects the extra implants and longer surgery time.

Per-Arch Pricing

Treatment	UK Private Price	Turkey Price	Savings
All-on-4 (standard implants)	£12,000 - £15,000	£4,000 - £5,500	60-67%
All-on-4 (premium implants)	£15,000 - £20,000	£5,500 - £7,500	60-65%
All-on-6 (standard implants)	£15,000 - £18,000	£5,000 - £7,000	60-67%
All-on-6 (premium implants)	£18,000 - £25,000	£7,000 - £10,000	60-65%

Full Mouth (Both Arches)

Treatment	UK Private Price	Turkey Price	Savings
All-on-4 both arches (standard)	£22,000 - £28,000	£7,500 - £10,000	64-66%
All-on-6 both arches (standard)	£28,000 - £34,000	£9,500 - £13,000	62-66%

These prices include implants, prosthetic arch, consultation, imaging, and standard aftercare. Bone grafting costs extra if you need it.

When All-on-4 Works Better

You have bone loss. All-on-4 was invented for this exact problem. If traditional implants won't work because you don't have enough bone, All-on-4 might still be possible without grafting.

You want to skip bone grafting. Bone grafts add 3-6 months and significant cost. All-on-4's angled technique usually avoids this.

Budget matters. Two fewer implants = lower cost. For both arches, the savings add up.

Speed matters. Fewer implants mean shorter surgery and easier same-day teeth placement.

When All-on-6 Works Better

Your bone density is good. If bone loss isn't your main problem, six implants give better force distribution without needing the angled approach.

You grind your teeth. Bruxism puts serious stress on implants. Six anchor points handle this better than four.

You want maximum durability. If one implant fails (rare but possible), you still have five supporting the prosthetic while a replacement gets placed.

You have a larger jaw. Bigger jaw structures benefit from wider implant distribution across the full arch span.

You eat challenging foods. Steaks, nuts, crusty bread — the extra bite force capacity of All-on-6 handles demanding diets better.

Recovery Comparison

Recovery Stage	All-on-4	All-on-6
Immediate post-surgery swelling	Moderate (2-3 days)	Moderate to significant (3-5 days)
Soft food diet	2-4 weeks	2-4 weeks
Return to normal activities	3-5 days	5-7 days
Temporary prosthetic worn	3-6 months	3-6 months
Final prosthetic fitted	4-6 months post-surgery	4-6 months post-surgery
Full osseointegration	3-6 months	3-6 months

All-on-6 involves more surgical work, so expect slightly more swelling initially. By two weeks, comfort levels are similar for both procedures.

Getting Your Assessment

Your bone density, jaw structure, and bite habits determine which option suits you. An online dental assessment narrows this down before you travel.

A MyDentalFly assessment covers:

Which teeth need extraction or are already missing
History of bone loss or gum disease
Eating habits and lifestyle factors
Previous dental work and complications

Clinics use this information for preliminary recommendations and accurate quotes for both options. The final decision usually requires a 3D CBCT scan at the clinic, but the assessment gets you 90% of the way there.

Frequently Asked Questions

Can I get All-on-4 on one arch and All-on-6 on the other?

Yes. Your upper jaw (maxilla) typically has softer bone, making All-on-4 with angled implants practical. Your lower jaw (mandible) often has denser bone that supports All-on-6 well. Each arch gets treated based on its specific bone density.

How long do these implants last?

The titanium implants can last your lifetime with proper care. The prosthetic teeth typically last 15-25 years before needing replacement due to normal wear. All-on-6 may give slightly longer prosthetic life due to reduced stress per implant, but modern materials make the difference small.

How painful is the surgery?

Both procedures use local anaesthesia, often with sedation. No pain during surgery. Post-surgical discomfort peaks on days 2-3, then subsides. Most patients say it's less painful than they expected.

Do I need a second trip?

If you get same-day teeth, you receive temporary prosthetics on your first visit and return after 3-6 months for the permanent fitting. Some clinics offer remote monitoring during healing and can reduce the second visit to just 2-3 days for final fitting.

What implant brands do Turkish clinics use?

The same brands used in UK, USA, and European clinics. Premium options include Straumann (Swiss) and Nobel Biocare (Swedish). Standard options include Osstem (Korean) and MIS (Israeli). All have extensive research supporting their use in full-arch procedures. Your assessment helps determine which brand fits your case and budget.
