When considering options to replace a full arch of missing teeth, All on 4 and All on 6 dental implants are excellent options. Both offer long-term stability and a natural feel. With that said, there are some key differences that may make one more suitable for you. Understanding how they compare can help you make an informed choice that fits your goals and your specific needs.
The two procedures are extremely similar and have more in common than not. Both involve the use of dental implants to hold prosthetics in place. This involves the placement of titanium rods into the jawbone, which then fuse into place. They are both secure options that allow you to bite, chew, and speak in a way that is similar to natural teeth. They also don’t slip as dentures do. Both All on 6 and All on 4 help to keep your jawbone strong and healthy as well by helping to avoid jawbone deterioration.
The primary difference lies in the number of implants used. All on 4 uses four implants per arch, while All on 6 uses six. This change might seem minor at first glance, but it makes a difference in both support and pressure distribution. With six implants, biting forces are shared more evenly, which can improve the durability of the prosthetic and reduce stress on individual implants.
Patients who have stronger biting forces or want added peace of mind often choose All on 6 for the extra reinforcement it provides. That said, All on 4 may be recommended when bone availability is limited, as it’s designed to make the most of the existing structure without requiring grafting in many cases.
What do they have in common?
Yes. All on 6 are generally more expensive, as there are more implants that need to be placed. With that said, some patients see the added investment as worthwhile—especially if they’re looking for maximum support or have concerns about long-term wear.
Both systems can deliver excellent results, and each has its strengths. The best way to decide is through a detailed consultation with your dentist or oral surgeon. They’ll assess your current oral health, take 3D scans of your jawbone, and consider your preferences before making a recommendation.
How are they different?
Whether you end up with four implants or six, the goal is the same: to give you a secure, lasting smile that looks and feels natural. With the right guidance, you’ll find the solution that fits your needs and helps you move forward with confidence.
