All-on-4 vs All-on-6: Which Full Mouth Implant Technique Is Right for You?
Two proven techniques. One restored smile. Here’s how to choose between All-on-4 and All-on-6.
What Are All-on-4 and All-on-6 Implants?
Both All-on-4 and All-on-6 are full-arch restoration techniques that replace all teeth in one jaw using dental implants. Instead of placing individual implants for each tooth, 4 or 6 implants are used to anchor a full set of fixed teeth.
Key Differences Between All-on-4 and All-on-6
| Feature | All-on-4 | All-on-6 |
|---|---|---|
| Number of Implants | 4 per arch | 6 per arch |
| Stability | High | Very high |
| Best For | Low bone volume, faster treatment | Bruxism, stronger bone, higher durability |
| Surgery Time | Shorter | Slightly longer |
| Cost | Lower overall | Higher overall |
All-on-4 is often chosen for quicker recovery and fewer surgical needs, especially in patients with limited bone volume. All-on-6 offers greater distribution of bite forces, making it ideal for heavy chewers and long-term resilience.

Is One Better Than the Other?
All-on-4 is typically used for the lower jaw, where bone density is often higher and fewer implants are needed. All-on-6 is generally preferred for the upper jaw due to the need for more support and distribution. However, we always perform full 3D scans and CBCT imaging to assess each client individually.
We don’t believe in one-size-fits-all dentistry. At HospitalOne, every treatment plan is tailored for long-term function and aesthetics. We promise results that last—no shortcuts, no shoddy work.
Not necessarily. It depends on your bone density, oral habits, budget, and long-term goals. At HospitalOne, we use 3D scans and CBCT to assess your suitability and create a personalised plan.
