All-on-4 vs All-on-6: Which Full-Arch Implant Solution is Right for You?

When patients have lost most or all of their teeth, they face a choice between All-on-4 and All-on-6 — two protocols that look similar but differ in important clinical ways.

If you have been told you need full-arch tooth replacement — either because you have lost most of your teeth, or because remaining ones must be extracted due to severe disease — you have most likely encountered the terms All-on-4 and All-on-6. They sound similar, and on the surface they are: both place dental implants and a fixed bridge of teeth. But the clinical decisions behind choosing one over the other matter for the long-term outcome.

This guide explains the difference, who benefits from each, and how the decision is made at WeCare Dental Clinic in Antalya.

What All-on-4 Actually Is

All-on-4 was developed by Nobel Biocare and trademarked in the early 2000s. The concept: replace an entire arch of teeth (12 teeth) using only 4 strategically placed implants instead of the 6-8 used in traditional full-arch protocols.

The innovation is angle. The two front implants are placed vertically. The two rear implants are placed at a 30-45° angle, which lets them use the maximum available bone in the front of the jaw — bypassing areas where bone has shrunk after tooth loss.

A temporary acrylic bridge is screwed onto the four implants on the same day, which is why "teeth in a day" became the famous All-on-4 promise. The final permanent bridge (zirconia or hybrid) is placed 3 months later after osseointegration.

What All-on-6 Adds

All-on-6 places 6 implants per arch — 4 vertical + 2 angled. The additional 2 vertical implants in the middle of the jaw provide:

1. More bite-force distribution — load is spread across 6 anchors instead of 4

2. Better safety margin — if 1 implant fails (rare), the remaining 5 still support the bridge

3. Better long-term durability for patients with heavy bite forces (bruxism)

Who Should Get Each

All-on-4 is the right choice when:

You have moderate bone density (most patients)

You do not have severe bruxism or teeth grinding

You want the simplest, fastest treatment

Your budget needs to stay tight (4 implants vs 6)

You have moderate bone loss in the rear of the jaw

All-on-6 is the right choice when:

You have very heavy bite force (athletes, manual laborers)

You have a history of teeth grinding (bruxism)

You have very dense bone that can support more implants

You want the maximum safety margin against future implant failure

The dentist has noticed unusual occlusion patterns during examination

How the Decision is Made at WeCare

We do not make this decision based on price. The deciding factors are:

1. 3D CBCT scan analysis — measures bone volume in millimeters, identifies areas of severe atrophy

2. Bite force assessment — clinical examination of jaw movement, history of grinding, history of cracked teeth

3. Diabetic / smoker status — both increase implant failure risk; All-on-6 provides more redundancy

4. Patient age and life expectancy — younger patients (under 50) often benefit from the extra durability of All-on-6

5. Patient priority — fastest treatment vs maximum durability is sometimes a trade-off

In about 70% of cases, All-on-4 is the right answer. The other 30% benefit from All-on-6.

Surgical and Clinical Differences

Both have excellent long-term outcomes. The differences are real but small.

Same-Day Teeth — Realistic Expectations

The "teeth in a day" promise is real but with conditions. On day 2 of your visit:

1. Surgery is performed under local anesthesia + IV sedation if requested. 2-4 hours per arch.

2. The temporary acrylic bridge is screwed onto the implants while you are still in the chair.

3. You leave the clinic with a complete set of teeth.

What you get is a temporary fixed bridge. It is functional for soft-to-medium foods. It is aesthetically pleasing. But it is acrylic, not porcelain, and it is not designed for hard biting (steak, raw vegetables, hard bread). The temporary phase lasts 3 months while your implants integrate with the bone.

The final permanent bridge is placed at month 4. This is zirconia or hybrid (zirconia + acrylic), much more durable, and designed for normal everyday eating.

What the 3-Month Healing Phase is Like

This is the phase that surprises most patients. While you are at home with the temporary bridge:

Diet: Soft foods for 2 weeks (smoothies, mashed potatoes, soups, well-cooked pasta), then medium-soft for the remaining 10 weeks (fish, well-cooked vegetables, pasta, soft bread). Avoid hard foods (steak, raw apples, hard bread).

Hygiene: Brush gently around the bridge with a soft brush. Use the special interdental brush we provide for cleaning under the bridge.

Activity: Normal daily life. Avoid intense gym activity for 2 weeks; otherwise no restrictions.

Communication: WhatsApp check-ins from the clinic every 2-3 weeks. We monitor your progress and address any concerns.

Cost Comparison and Value

All-on-6 typically costs 20-25% more than All-on-4 because of the additional 2 implants. For most patients, this premium is worth paying if there is even a 50/50 case for needing more support — bone density is dense enough, or bite force is heavy.

For European medical tourism patients, the total cost of All-on-4 in Turkey (per arch, all-inclusive of hotel + transfers + multilingual coordinator) is roughly equivalent to 1/4 of UK private pricing or 1/3 of German private pricing.
