All on 4 and All on 6 dental implants are two popular options for full-arch tooth replacement. Both procedures use dental implants to support a full set of prosthetic teeth, but the number of implants and how they distribute pressure across your jaw are what set them apart. Understanding the differences between these two options can help you decide which one is right for your situation.
All on 4 uses four implants per arch, placed strategically to support a full row of teeth. The back implants are usually angled to use available bone and avoid certain areas like sinuses or nerves. All on 6 uses six implants instead of four. The additional implants help distribute pressure across the jaw and may increase overall stability, especially in cases where bone structure is strong.
All on 6, on the other hand, uses six implants instead of four. These extra implants can offer added support and stability. Because the pressure from chewing is spread out across more points, All on 6 may reduce stress on any one area of the jaw. This can lead to better long-term performance and less risk of implant failure, especially in people with strong, healthy bone structure.
When it comes to durability, both systems are designed to be long-lasting. The success of either approach depends on factors like implant placement, bone health, and how well you care for your teeth afterward. People who brush daily, avoid tobacco, and see their dentist regularly are more likely to have long-term success, regardless of whether they choose All on 4 or All on 6.
The cost difference between the two is also something to consider. Because All on 6 involves more implants and a longer surgery, it typically costs more than All on 4. However, some people are willing to make that investment for the added stability and peace of mind. Both systems may offer temporary teeth on the same day as surgery, followed by a healing period and a final set of permanent teeth.
Your dentist will guide you toward the best option after evaluating your mouth, taking X-rays or scans, and discussing your personal goals. If you have lost a lot of bone, All on 4 may be better suited to avoid extra procedures. If your jaw is in good condition and you want extra reinforcement, All on 6 might be a better match.
No matter which option you choose, both treatments aim to restore your ability to chew, speak, and smile confidently. They are fixed solutions, which means you won’t have to remove them like dentures. Many patients say that after getting either All on 4 or All on 6, their quality of life improves significantly.
Before moving forward, make sure to ask about cost, timelines, recovery steps, and what kind of maintenance will be needed over time, and when might be the best time to schedule your procedure. A clear understanding of the process can help you feel more comfortable and confident in your decision.
