All-On-X is a term for replacing “all” of your teeth with “X” strategically placed dental implants per jaw. The most well-known version “All-On-4®” simply means four implants, while “All-on-6” refers to six implants, and so on. These X implants then support a complete set of permanent replacement teeth that look, feel, and function just like your natural teeth.
All-on-X replaces your entire upper or lower set of teeth using dental implants. The “X” means the number of implants can vary, usually 4 to 6 implants, based on what works best for you. These implants hold your permanent teeth in place, giving you back a complete, functional smile.
All-On-X dental implants are a modern tooth replacement solution for patients missing multiple teeth or an entire arch, typically just four or six strategically placed implants to support a full set of replacement teeth. The treatment is efficient and fast, and can typically be completed in less than 24 hours, with temporary teeth placed immediately and permanent prosthetic teeth installed after a healing period.

They are essentially different terms for a similar procedures. The term “All-on-X” is a more general term, that refers to placing an entire arch of teeth on “X” number of implants, where as All-on-4® specifically means entire arch on just four implants. Older implant treatments required more implants (6, 8 or sometimes more) per jaw for stability. Thanks to modern technology, All-on-4® achieves the same strong, secure results. The number of implants you may need to support an upper or lower arch will depend on your specific situation.
All-on-4® and All-on-X/All-on-6 dental implants differ primarily in the number and placement of implants used to support full-arch prosthetics. The All-on-4 procedure uses four strategically angled implants per arch, while All-on-6 employs six straight, parallel implants with two additional supports placed closer to the back of the jaw.
The additional implants in All-on-6 can provide enhanced stability and strength, which can benefit patients with very long dental arches where four implants alone might lead to fracture and breakage of the final prosthesis. The extra implants help minimize the “cantilever effect” that can cause prosthesis issues, whereas All-on-4 achieves this through slightly tilted outer implants to reduce stress on the restoration.
However, All-on-6 typically requires more existing bone for proper placement and has a higher likelihood of requiring bone grafting procedures, especially since the additional implants are positioned in the back areas of the mouth where bone is generally more limited. This increased complexity makes All-on-6 typically more expensive, due to the additional implants and their prosthetic components.
From a maintenance perspective, All-on-6 can present more cleaning challenges since there are additional implant posts that require careful hygiene care between them.
Takeaway: we would discuss which approach works best for you. Ultimately, the choice between these approaches depends on a number of factors, including a patient’s jawbone condition, oral health status, the length of their dental arch, budget considerations, and their ability to maintain proper oral hygiene around the implant sites.
All-on-X is ideal for people who have lost most or all of their teeth due to decay, damage, gum disease, or injury. The implants are specially designed to bond naturally with your jawbone, creating a strong foundation for your new teeth.
Your newly placed teeth will provide full chewing power and look completely natural. Unlike removable dentures that can slip while eating or talking, All-on-X stays securely in place. This prevents bone loss, maintains your facial structure, and gives you clear speech and confident smiles.
The alternatives to All-on-X include dentures, bridges or multiple implants. All-on-X is appealing because it allows patients to regain a full set of upper and/or lower teeth without the need to wear full dentures or undergo multiple dental implant surgeries.
The most common alternative to All-on-X dental implants are old-fashioned dentures that sit on top of the gums where the missing teeth were. They can be uncomfortable, affect your ability to experience the full taste of food, cause sore gums, and shift and click in your mouth when you speak, eat, smile, yawn or cough.
Other considerations
In contrast, All-On-X dental implants offer significant benefits compared to traditional dentures:
Not sure which treatment is right for you? Explore implants for a single tooth, implant-supported bridges for multiple teeth, or comprehensive full mouth implant solutions including All-on-X systems that secure entire arches with fewer implants. Advanced options like zygomatic and pterygoid implants serve patients with insufficient bone, while full mouth reconstruction combines implants with restorative work for complete smile transformation.
