Introduction
Losing an entire arch (or both arches) of teeth can be life-changing: it affects chewing, speech, facial aesthetics and self-confidence. Fortunately modern implant dentistry offers excellent solutions — among the most popular are the All-on-4, All-on-6, and All-on-8 full-arch implant protocols. Each offers significant advantages—but the optimal choice depends on your bone anatomy, functional demands, aesthetic goals, budget and long-term plan.
In Istanbul, Turkey, Dream Clinica has earned a strong reputation as a leader in full-arch solutions, offering state-of-the-art care, digital planning, premium implant systems and medical-tourism packages that cater to international patients. dreamclinica.com+1
This comprehensive article will:
- explain the three protocols (All-on-4, All-on-6, All-on-8)
- compare them side-by-side (indications, pros/cons, cost, longevity)
- guide you on how to choose the best based on your personal situation
- highlight why Dream Clinica in Istanbul might be your best partner for full-mouth restoration.
What are the Protocols?
All-on-4
The term All-on-4 refers to a full-arch fixed prosthesis supported by four dental implants (typically made of titanium) placed in the jaw (upper or lower). The implants are strategically positioned — usually two more vertical in the anterior region and two angled posteriorly — to maximize bone engagement and avoid critical anatomical structures.
The “All” means “all the teeth in that arch” are replaced on that fixed prosthesis.
Key features:
- Four implants per arch.
- Often used when bone availability is moderate but you seek a fixed (non-removable) solution.
- May allow immediate loading (i.e., provisional prosthesis placed the same day) if primary stability is adequate.
- Lower cost compared to protocols using more implants.
Advantages:
- Fewer implants = less surgical time, less trauma, often faster recovery.
- Good outcome for many patients with moderate bone volume.
- Popular and proven with many years of clinical experience.
Limitations:
- The load per implant is higher than if you used more implants, which can increase biomechanical stresses.
- If the bone is very weak or you have bruxism (heavy grinding), this protocol may be less ideal.
- The posterior implants are often angled, which while beneficial has own considerations (prosthetic access, cleaning, maintenance).
All-on-6
The All-on-6 protocol uses six implants per arch supporting a fixed full-arch prosthesis.
Key features:
- Six implants rather than four.
- Provides more anchorage and better load distribution across the arch.
- Particularly useful when bone is good or when functional demands are higher.
Advantages:
- Enhanced stability and strength: more implants spread the load, reducing stress per implant.
- Better future-proofing for heavy chewing, bruxism, or larger prosthesis spans.
- Slightly better bone preservation in some cases because load is more evenly distributed.
Limitations:
- Slightly increased cost vs All-on-4 (more implants, more components).
- Slightly more invasive: more sites to drill and place implants.
- May still eventually require adjustments, maintenance or replacement of the prosthesis—but with better margin.
All-on-8
The All-on-8 protocol uses eight implants per arch to support the full-arch fixed prosthesis.
Key features:
- Eight implants = maximised support.
- Best suited for patients with excellent bone volume or those who desire maximum durability and long-term load bearing (for example heavy eaters, patients who want “the best of the best”).
- Might be considered as a “premium” full-arch restoration plan.
Advantages:
- Lowest stress per implant due to more implants sharing the load.
- Potentially longest lifespan of prosthesis (when combined with good maintenance).
- More options for prosthetic design, stronger bracing, better aesthetics and function.
Limitations:
- Highest cost among the three protocols.
- More surgical time, more healing, possibly more discomfort initially.
- Not always necessary for every patient; may be “over-engineering” for those with moderate needs.
Side-by-Side Comparison
| Feature | All-on-4 | All-on-6 | All-on-8 |
|---|---|---|---|
| Number of implants | 4 | 6 | 8 |
| Ideal when bone volume is … | Moderate / borderline | Good | Excellent |
| Load per implant | Highest | Medium | Lowest |
| Cost | Lowest of three | Moderate | Highest |
| Surgical time / invasiveness | Least | Moderate | Most |
| Repair/replacement margin | Smaller | Better | Best |
| Long-term durability | Very good | Superior | Top tier |
| Best for | Patients with limited budget or moderate bone | Patients wanting a robust solution | Patients wanting premium, heavy function, maximal durability |
Which One is Right for You?
Choosing among All-on-4, All-on-6 or All-on-8 depends on multiple factors:
- Bone quantity & quality
If bone height/width is limited or anatomically compromised (sinus, nerve proximity), you may need fewer implants and rely on angulation (All-on-4) or may need grafting.
If you have ample good bone then All-on-6 or All-on-8 may make sense. - Functional requirements
Do you grind your teeth (bruxism)? Do you eat hard foods? Are you very active? The heavier the usage, the more you may benefit from additional implants (All-on-6 or 8). - Budget & financing
The cost difference can be significant. All-on-4 offers excellent value; All-on-8 offers maximum strength but at higher cost. - Long-term plan
If you plan to keep the prosthesis for many decades and want “maximum safety margin”, 8 implants may make sense. If you’re comfortable that 4 or 6 will do given your maintenance and care, then those may suffice. - Surgeon/clinic expertise
The technology (3D CBCT scans, guided surgery, premium implant systems), the surgical team and the prosthetic lab all matter. The best outcomes come when you match your case to a clinic that offers full digital diagnostics and long-term service.

FAQs
Q: How long do full-arch implants last?
A: With proper care, full-arch implant prostheses (4, 6 or 8 implant supported) can last 15-20 years or more. Choosing more implants (6 or 8) gives better “margin” for longevity.
Q: Is bone grafting always needed?
A: Not always. If you have sufficient bone, grafting may be avoided. Protocols like All-on-4 are designed to minimise grafting by strategic implant placement and angulation.
Q: How much will it cost?
A: Costs vary by clinic, country, number of implants, implant system, prosthesis type. Turkey tends to offer more affordable pricing compared to Western Europe/US, while maintaining high standards (as seen at Dream Clinica).
Q: Can I have the prosthesis on the same day?
A: Yes — if conditions allow (good bone, primary stability achieved), many clinics including Dream Clinica offer immediate loading, meaning a provisional fixed bridge on the same day of surgery.
Q: What’s the difference between the prosthesis types?
A: The bridge material may differ (hybrid acrylic/metal, zirconia, porcelain layered). The number of implants affects stability and how thin/long the prosthesis can be. More implants = potentially slimmer design, better aesthetics.
