Choosing the Right Full Arch Dental Implant Treatment
If you’ve lost most or all of your teeth, or if your current dentures are affecting your confidence and comfort, full arch dental implants offer a life-changing solution. But when researching your options, you’ll likely come across two common techniques: All-on-4 and All-on-6.
So, what’s the difference between them? And more importantly — which is the best option for you?
In this guide, we explain both techniques, compare their benefits, and help you decide which approach offers the right long-term solution for your smile, health, and lifestyle.
What Are Full Arch Implants?
Full arch dental implants are designed to replace an entire row of missing teeth using a fixed bridge supported by dental implants. Unlike traditional dentures, they are permanently secured in the jaw and look, feel, and function just like natural teeth.
Depending on your clinical needs, your dentist may recommend either:
- All-on-4 implants: A full arch supported by four strategically placed implants
- All-on-6 implants: A full arch supported by six dental implants for added stability
Both techniques typically allow for a same-day smile transformation, often referred to as “Teeth in a Day.”

What Is the All-on-4 Technique?
The All-on-4 system uses four dental implants — two placed vertically at the front of the jaw and two tilted implants placed further back — to support a full arch prosthetic.
Key Benefits:
- Requires fewer implants, which can reduce cost
- Often suitable for patients with limited bone volume
- Less invasive than traditional multiple implants
- Faster recovery with same-day temporary teeth
Best For:
- Patients with moderate bone loss
- Those seeking a cost-effective fixed solution
- Candidates prioritising minimally invasive surgery
What Is the All-on-6 Technique?
The All-on-6 approach uses six implants per arch, offering greater distribution of force and additional support for the prosthetic bridge. More implants can improve long-term stability and durability, especially in the back teeth (molars) where chewing forces are strongest.
Key Benefits:
- Increased support and implant stability
- Better load distribution across the jaw
- Reduced risk of long-term complications or bridge failure
- Often associated with longer prosthetic lifespan
Best For:
- Patients with adequate bone density
- Those with higher bite forces or bruxism
- Long-term implant durability and peace of mind
Side-by-Side Comparison: All-on-4 vs All-on-6
| Feature | All-on-4 | All-on-6 |
| Number of implants | 4 per arch | 6 per arch |
| Cost | Lower (from £12,000) | Higher (due to more implants) |
| Surgery complexity | Less invasive | More surgical time, more bone needed |
| Stability | Very good | Excellent |
| Bone requirements | Lower | Higher |
| Long-term strength | Suitable for most patients | Ideal for those with strong bite |
| Prosthetic longevity | 10–15 years (bridge) | 12–15+ years (bridge) |
Which Option Is Right for You?
Choosing between All-on-4 and All-on-6 will depend on several clinical and personal factors. Here’s what we typically assess during your dental implant consultation:
- Bone density and jaw health
CBCT imaging helps us evaluate whether you have sufficient bone to support 4 or 6 implants, and whether bone grafting may be needed. - Bite force and grinding habits
If you suffer from bruxism (teeth grinding) or place a lot of force on your bite, All-on-6 may offer better long-term durability. - Budget and treatment goals
While All-on-4 can be more affordable, both treatments represent a significant investment in your oral health. Finance options are available for both. - Aesthetic goals
Both systems offer excellent cosmetic outcomes — we use high-quality prosthetics designed to look and feel like real teeth.

We offer flexible finance options, including 0% interest for 12 months and extended payment plans, to help spread the cost.
Do Both Options Offer “Teeth in a Day”?
Yes. Both All-on-4 and All-on-6 allow for immediate loading, which means a temporary bridge is fitted on the same day as implant surgery.
This gives you a fully functioning, natural-looking smile from day one. Your final prosthetic will usually be fitted 3–6 months later, once healing is complete.
Patient Case Study: John, 64
“I was recommended All-on-6 because of my bite and bone levels. The procedure went smoothly, and I walked out with a new smile. It’s the best decision I’ve made for my health and confidence.”
— John, real patient
Dentist’s Opinion: All-on-4 or All-on-6?
Both options are excellent — but All-on-6 offers added support and longevity, particularly for patients with good bone health and higher bite forces. However, All-on-4 is a brilliant, proven option for those needing a more minimally invasive approach with fewer implants.
The best treatment is the one that suits your mouth, your lifestyle, and your long-term goals.
