All-on-4 vs All-on-6: Choosing the Right Full-Arch Solution
Dr. Sadık Taki
Specialist Prosthodontist · Artemis Dental, Antalya
Making the decision to restore an entire arch of missing or failing teeth is a significant step. It is a journey that involves not just clinical choices, but also considerations of comfort, confidence, and long-term value. If you are a UK patient exploring options in Turkey, particularly in Antalya, the terms *All-on-4* and *All-on-6* will quickly become familiar. Both are proven, life-changing solutions, but they are not interchangeable. Understanding the difference is key to choosing the path that best supports your health, your lifestyle, and your peace of mind.
Let’s walk through the details together, calmly and clearly.
What These Terms Actually Mean
At their heart, both All-on-4 and All-on-6 are techniques for securing a full arch of fixed teeth using dental implants. The numbers refer to the number of implant posts placed into the jawbone. These implants act as artificial roots, providing a stable foundation for a permanent bridge.
- All-on-4: Uses four implants per arch. The two front implants are placed vertically, while the two rear implants are angled to maximise contact with available bone, often avoiding the need for bone grafting.
- All-on-6: Uses six implants per arch. All six are typically placed vertically, offering more points of fixation and distributing chewing forces over a wider area.
Both approaches aim to give you a fixed, non-removable set of teeth that look, feel, and function much like natural ones.
The Clinical Differences: Stability, Bone, and Load
The primary difference lies in the biomechanics. With more implants, the load from chewing is spread across a greater surface area. This can be particularly important for patients who have a strong bite, grind their teeth, or want the most robust long-term solution.
All-on-4 was pioneered to address a common problem: insufficient bone in the back of the jaw. By tilting the posterior implants, the technique often avoids the need for sinus lifts or bone grafts, making it a faster, less invasive procedure. It is a clever, well-established solution for many patients.
All-on-6, however, offers a different kind of security. Because there are six points of fixation, the bridge is supported more evenly from front to back. This can reduce the risk of prosthetic fractures over time and often allows for a longer bridge without the need for cantilevers (extensions beyond the last implant). For patients with adequate bone height and width, All-on-6 is frequently the preferred choice for long-term durability.
Here is a simple comparison to help you visualise the key factors:
| Factor | All-on-4 | All-on-6 |
|---|---|---|
| Number of implants | 4 per arch | 6 per arch |
| Bone requirement | Lower; works well with moderate bone loss | Higher; requires adequate bone volume |
| Invasiveness | Less invasive; often no grafting needed | More invasive; may require grafting |
| Treatment time | Often shorter | Slightly longer due to extra implant placement |
| Long-term stability | Excellent | Excellent; potentially superior load distribution |
| Cost | Generally lower | Generally higher |
Who Is the Ideal Candidate for Each?
There is no single answer for everyone. Your suitability depends on your jawbone density, your overall health, and your personal goals.
All-on-4 may be the right choice if:
- You have experienced significant bone loss in the back of your jaw.
- You wish to avoid bone grafting or sinus lifts.
- You are looking for a less invasive procedure with a quicker recovery.
- Your budget is more limited, but you still want a high-quality fixed solution.
All-on-6 may be the right choice if:
- You have good bone volume throughout your jaw.
- You want the most robust, long-lasting foundation possible.
- You have a heavy bite or clench/grind your teeth.
- You are willing to undergo a slightly longer procedure for added security.
It is important to note that many patients who are told they need All-on-4 due to bone loss are actually candidates for All-on-6 after a careful evaluation. A thorough 3D CT scan is essential to determine your true bone anatomy.
The Patient Experience: What You Can Expect
Whichever option you choose, the journey is remarkably similar. You will have a consultation, a digital scan, and a treatment plan. On the day of surgery, you will be sedated or given local anaesthesia. The implants are placed, and in most cases, a temporary fixed bridge is fitted the same day. You leave with teeth.
The recovery period involves some swelling and a soft-food diet for a few weeks. After three to six months, once the implants have fully integrated with the bone (a process called osseointegration), your final, permanent bridge is fitted.
With All-on-4, the initial recovery is often slightly easier because there are fewer surgical sites. With All-on-6, the extra implants mean more surgical work, but the long-term stability can be very reassuring.
Long-Term Maintenance and Longevity
Both systems are designed to last decades, but they require care. You must brush and floss around the implants daily, and you will need regular professional check-ups. The prosthetic bridge itself may need replacement after 10–15 years, depending on wear and tear.
In terms of longevity, All-on-6 has a theoretical advantage. With more implants, the load is better distributed, which may reduce stress on the bridge and the bone. Some studies suggest a lower rate of prosthetic complications with six implants over very long periods. However, All-on-4 has an excellent track record and remains the gold standard for patients with limited bone.
Why Antalya and Why This Matters
For UK patients, the cost difference between these two options can be substantial. In the UK, All-on-4 typically ranges from £18,000 to £25,000 per arch, while All-on-6 can be £25,000 to £35,000 or more. In Antalya, these figures are often 50–70% lower, even including flights and accommodation.
This price difference makes it possible for many patients to choose the more robust All-on-6 solution when they might have settled for All-on-4 at home. It is a genuine opportunity to upgrade your treatment without stretching your finances.
Making Your Decision
Choosing between All-on-4 and All-on-6 is not about which is "better" in a general sense. It is about what is better *for you*. A skilled clinician will assess your bone density, your bite force, your medical history, and your aesthetic goals before making a recommendation.

Final Thoughts
Both All-on-4 and All-on-6 are transformative treatments. They restore your ability to eat, smile, and speak with confidence. The right choice for you will depend on a careful, honest assessment of your oral health and your priorities.
If you have good bone and want the most durable foundation possible, All-on-6 is often the superior choice. If you have significant bone loss or prefer a less invasive procedure, All-on-4 remains a superb, time-tested solution.
Whichever path you take, working with an experienced clinic that understands the nuances of both techniques is essential. Take your time, ask questions, and trust the process. Your smile is worth it.
Frequently asked questions
What is the main difference between All-on-4 and All-on-6 implants?
The key difference is the number of implants used to support a full arch of teeth. All-on-4 uses four strategically placed implants, while All-on-6 uses six. All-on-6 generally provides greater stability and is often recommended for patients with sufficient bone density, whereas All-on-4 is designed for cases where bone volume is more limited, often avoiding the need for bone grafting.
Which option is more suitable if I have bone loss in my jaw?
All-on-4 is often the preferred choice for patients with moderate bone loss, as the angled placement of the rear implants maximises contact with available bone. All-on-6 typically requires more bone volume. A thorough CT scan at your chosen clinic will determine your bone density and guide the recommendation. Both options can be viable with proper assessment.
Are All-on-6 implants more durable or longer-lasting than All-on-4?
Both systems are highly durable and can last 15–20 years or more with excellent oral hygiene and regular check-ups. The added implants in All-on-6 can distribute biting forces more evenly, which may reduce wear on the prosthetic teeth over time. However, long-term success depends more on your aftercare than the implant count alone.
How do I choose between All-on-4 and All-on-6 for treatment in Antalya?
