Ask three different clinics about full-arch dental implants and you’ll often get three different recommendations. One suggests All-on-4, another pushes All-on-6, a third mentions zygomatic implants — and suddenly you’re trying to make a major decision about your mouth without a clear way to compare the options.
This guide breaks down every full-arch implant option available at GD Smile Studio in plain terms: how each one works, who it actually suits, and how they compare side by side. By the end, you’ll know exactly which questions to ask at your consultation.
How Full-Arch Dental Implants Work
Full-arch implant treatment replaces an entire row of missing or failing teeth using a small number of titanium (or zirconium) implants placed strategically in the jawbone, rather than one implant per missing tooth. A fixed prosthetic bridge is then attached on top, giving you a complete, non-removable set of teeth.
The number of implants used — four, six, eight, or a segmented six — changes how the chewing load is distributed across your jaw, and that’s really what separates the options below from one another. If you’re new to the topic, our complete dental implants in Turkey guide covers the basics of the process, timeline, and what your trip to Istanbul looks like.
Quick note: The right option for you depends on your jawbone density and how many teeth you’ve already lost — not personal preference alone. A 3D scan during your free consultation determines which of the options below you actually qualify for.
All-on-4 Dental Implants
All-on-4 uses four implants per arch — two placed upright at the front and two placed at an angle further back — to support a complete fixed bridge. The angled rear implants reach denser bone and often avoid the sinus cavity entirely, which is what allows an entire arch to be supported with just four fixture points, and in many cases fitted with a temporary fixed bridge on the same day as surgery.
All-on-4 tends to suit you if:
- You have moderate bone loss but want to avoid extensive grafting
- You’re replacing most or all teeth in an arch and want the most time- and cost-efficient route to fixed teeth
- You’d like temporary fixed teeth on the day of surgery while your final bridge is prepared
- A 3D scan confirms adequate bone density at the four planned implant positions
Worth knowing: Because it uses fewer implants than All-on-6 or All-on-8, All-on-4 spreads bite force across fewer anchor points. For most patients with reasonable bone volume this isn’t an issue, but if your dentist finds more significant bone loss, they may recommend one of the options below instead. This is confirmed during your 3D scan, not guessed beforehand.

All-on-6 Dental Implants
All-on-6 follows the same principle as All-on-4 but uses two additional implants — six per arch instead of four. Those extra anchor points spread the chewing load more evenly across the jaw, which typically means better long-term stability and a bridge that can handle stronger bite forces without relying on just four contact points.
All-on-6 tends to suit you if:
- Your 3D scan shows enough bone density to support six implants without grafting
- You want a stronger, more evenly distributed foundation than All-on-4 offers
- You have a naturally strong bite or grind your teeth, and want extra anchorage to match
- You’re comfortable with a slightly longer, more involved surgery in exchange for added long-term stability
All-on-4 vs All-on-6: Neither is “better” in absolute terms — it comes down to your bone density and bite strength. All-on-4 is faster and more budget-friendly; All-on-6 adds redundancy and stability. Your dentist will recommend one over the other based on your scan, not the other way around.
See full details on All-on-6 dental implants at GD Smile Studio, including candidacy requirements and the treatment timeline.
All-on-8 Dental Implants
All-on-8 uses eight implants per arch, giving the highest level of redundancy among the count-based options. If one implant were ever to underperform, the remaining seven can still carry the prosthesis while it’s addressed — a margin of safety that matters most for patients with more extensive tooth loss or specific medical risk factors affecting healing.
All-on-8 tends to suit you if:
- You’ve lost the large majority of your natural teeth in the arch
- Your dentist identifies a medical or healing-related risk factor where extra anchor points add a safety margin
- You want the maximum redundancy available before considering more advanced options like zygomatic implants
- Your bone volume comfortably supports eight implant positions without grafting
Worth knowing: For most patients with reasonably good bone anatomy and a normal bite, All-on-6 already provides sufficient stability — All-on-8 is generally reserved for cases where your dentist specifically identifies a need for the extra support, rather than being a routine upgrade.
See full details on All-on-8 dental implants at GD Smile Studio.
3-on-6: How It’s Different from All-on-6
The number of implants is the same as All-on-6 — six per arch — but the prosthesis is built differently. Instead of one continuous bridge spanning the whole arch, the six implants support three separate four-unit bridge segments. At GD Smile Studio, this segmented approach is used specifically to make future maintenance simpler: if one segment ever needs attention, your dentist can address that section without touching the rest of your teeth.
3-on-6 tends to suit you if:
- You want the stability of six implants with easier long-term serviceability
- You’d prefer that a future repair only affects one section of your bridge, not the entire arch
- Your bone density and candidacy are otherwise similar to what All-on-6 requires
Worth knowing: “3-on-6” isn’t a universally standardised term across the implant industry — different clinics use it to describe slightly different setups. The description above reflects how it’s specifically approached at GD Smile Studio; always confirm the exact configuration with your dentist during your consultation.

Zygomatic Dental Implants — For Severe Bone Loss (No Bone Graft Needed)
Zygomatic implants solve a problem the options above can’t: severe upper jaw bone loss where there simply isn’t enough bone volume left to anchor standard implants, even with angling. Instead of anchoring in the jawbone, these longer implants are secured directly into the zygomatic bone — your cheekbone — which is dense, stable, and doesn’t resorb the way jawbone does after tooth loss.
Because they bypass the areas where bone has been lost, zygomatic implants avoid the need for bone grafting and the months of healing that typically come with it. In many cases, damaged teeth can be extracted and zygomatic implants placed in the same appointment.
Zygomatic implants tend to suit you if:
- Your 3D scan shows severe or advanced bone loss in the upper jaw
- You’ve been told by another clinic that you’d need extensive bone grafting before you could get implants
- You want to avoid the additional surgery and months-long healing time that grafting requires
- You have failing or failed previous implants due to bone loss and need an alternative anchor point
Worth knowing: Zygomatic implant placement is a more advanced surgical procedure than All-on-4/6/8, requiring specific surgical expertise. It’s generally recommended only when a 3D scan confirms standard full-arch options aren’t viable — not as a first-choice treatment.
See full details on zygomatic dental implants at GD Smile Studio.
Full Mouth Dental Implants — The Umbrella Term
You’ll often see “full mouth dental implants” used as a general term rather than a specific technique — and this trips a lot of patients up when comparing clinics. It typically just means replacing an entire arch (or both arches) with implant-supported fixed teeth, which is exactly what All-on-4, All-on-6, All-on-8 and 3-on-6 all are. In other words, “full mouth implants” describes the goal; the options above describe the specific method used to get there.
Worth knowing: If a clinic quotes you for “full mouth implants” without specifying which configuration, ask directly which of the options above they mean and why — the implant count and technique materially affect cost, timeline, and long-term stability.
See our full mouth dental implants page for a broader overview of the full-arch restoration process at GD Smile Studio.
Surgical Techniques: Flapless Surgery & Immediate Loading
All-on-4, All-on-6, All-on-8, and 3-on-6 describe how many implants are used. Flapless surgery and immediate loading describe how those implants are placed and restored — they’re techniques that can be applied to several of the options above, not separate alternatives to choose instead of them.
Flapless (Keyhole) Surgery
Traditional implant placement involves cutting back the gum tissue to expose the jawbone before placing the implant. Flapless surgery skips that step: guided by 3D imaging, the implant is placed through a small keyhole opening directly into the bone, without lifting the gum. This generally means less swelling, less discomfort, and a faster initial recovery.

Immediate Loading (Same-Day Teeth)
Conventional implants need a healing period — often several months — before a permanent crown or bridge is attached, so the bone can fuse to the implant (osseointegration). Immediate loading attaches a fixed provisional bridge on the same day as surgery instead, so you leave with functioning teeth right away. Your final, permanent bridge is fitted later, once healing is complete.
This is only possible when your implants achieve enough initial stability at the time of placement — something your surgeon confirms during the procedure itself, not before. It’s commonly paired with All-on-4, though it can apply to other configurations depending on your anatomy.

Zirconium (Metal-Free) Implants — A Material Choice, Not a Count
One more variable, separate from everything above: the implant material itself. Standard implants are titanium. Zirconium implants use a ceramic, metal-free alternative — usually chosen by patients who prefer to avoid metal in the body, or who have a known metal sensitivity. Zirconium can, in principle, be used within an All-on-4, All-on-6, or All-on-8 configuration; it’s a material decision layered on top of the count decision, not a separate implant type on its own.
Worth knowing: Zirconium implants aren’t suitable for every full-arch case — your dentist will confirm during your consultation whether it’s a fit for your specific treatment plan.

Comparison Table: All-on-4 vs All-on-6 vs All-on-8 vs 3-on-6 vs Zygomatic
Here’s every option from this guide side by side, so you can see at a glance how they differ before your consultation.
| Implant Type | Implants Used | Best For | Key Benefit |
|---|---|---|---|
| All-on-4 | 4 per arch | Moderate bone loss, budget- and time-conscious patients | Fastest, most cost-efficient route to fixed teeth |
| All-on-6 | 6 per arch | Good bone density, stronger bite force | More even load distribution, added stability |
| All-on-8 | 8 per arch | Extensive tooth loss, higher-risk healing profile | Maximum redundancy and support |
| 3-on-6 | 6 per arch (3 segments) | Patients who want easier future maintenance | Segmented bridge — repairs affect one section, not the whole arch |
| Zygomatic | 2–4 per arch (cheekbone-anchored) | Severe upper jaw bone loss | No bone graft needed, even with minimal jawbone remaining |
How to Know Which Option Is Right for You
You don’t need to arrive at a decision on your own. What follows are the main factors your dentist will weigh — useful to understand before your consultation, but not something you need to diagnose yourself.
- Bone density and volume: the single biggest factor. This is what a 3D scan is for, and it’s what ultimately narrows down your options from the list above.
- How many teeth you’re replacing: a full arch vs. near-total tooth loss can point toward different implant counts.
- Timeline: if same-day fixed teeth matter to you, that shapes which options and techniques are discussed first.
- Budget: more implants generally means a higher cost — but also potentially more stability. Your treatment plan will lay out the trade-off clearly, with no obligation attached.
- Any previous implant history: failed or failing implants due to bone loss often point toward zygomatic implants specifically.

Frequently Asked Questions
What is the difference between All-on-4 and All-on-6 dental implants?
Both replace a full arch with a fixed bridge, but All-on-4 uses four implants and All-on-6 uses six. The extra two implants in All-on-6 spread chewing force more evenly and can add stability, particularly for patients with good bone density and a strong bite. All-on-4 is generally faster and more cost-efficient. Your 3D scan determines which you’re a candidate for.
Do I need bone grafting for dental implants in Turkey?
Not necessarily. All-on-4, All-on-6, flapless surgery, and zygomatic implants were all developed specifically to reduce or eliminate the need for bone grafting. Whether you need grafting depends on your individual bone volume, confirmed by a 3D scan during your consultation.
What are zygomatic implants used for?
Zygomatic implants are used when upper jaw bone loss is too severe for standard full-arch implants, even with angled placement. They anchor into the cheekbone instead of the jawbone, avoiding the need for bone grafting entirely.
How long do full-arch dental implants last?
With proper care — good oral hygiene and regular check-ups — full-arch implants are designed as a long-term, decades-long solution. The prosthetic bridge on top may need replacement or adjustment over time depending on the material chosen, but the implants themselves are built to last.
Can I get same-day teeth with dental implants in Turkey?
Often, yes — this is called immediate loading, where a fixed provisional bridge is attached the same day as surgery. It’s commonly paired with All-on-4, but eligibility depends on the implants achieving enough initial stability at the time of placement, confirmed by your surgeon during the procedure.
Is 3-on-6 different from All-on-6?
The implant count is the same — six per arch — but 3-on-6 splits the prosthesis into three separate four-unit bridge segments instead of one continuous bridge. This makes future repairs simpler, since one segment can be addressed without affecting the rest of your teeth.
