What is All-on-4? A full smile on four implants.
All-on-4 replaces an entire arch of missing or failing teeth with a single, fixed set of natural-looking teeth — anchored on just four dental implants, and often placed in one visit. Here is exactly how it works, and why it changes everything for people ready to smile again.
4 implants
Anchor a full arch
One fixed arch
Not removable dentures
A whole arch, carried on four.
An arch is one full row of teeth — your upper set or your lower set. All-on-4 rebuilds that entire row at once. Rather than an implant for every tooth, four titanium implants are placed in the jaw and angled to make the most of your available bone.
Those four implants become the foundation for a single fixed bridge of beautiful teeth — secured in place so it never comes out. The result looks, feels, and functions like a healthy, natural smile, and it does the one thing removable dentures cannot: it stays.
One arch =
A complete upper or lower row of teeth — replaced together as one fixed unit.
Four implants =
The strong, angled foundation that holds your new teeth firmly in the jaw.
Not dentures. Not one-by-one.
All-on-4 sits between two familiar options — and improves on both.
Rest on the gums
Removable, held by suction or adhesive. They can slip while eating or speaking, and the bone beneath them tends to shrink over the years.
Anchored in the jaw
A full arch fixed to four implants. It stays put, protects your bone, restores real bite strength — and often goes in the same day.
One per tooth
Excellent for a few missing teeth, but restoring a whole arch this way can mean eight or more implants, more surgery, and more time.
The benefits that change lives.
Everything a removable plate can't offer — and a lot more than a smile.
A fixed, permanent smile
Your new arch is secured to the implants — it never comes out, never slips, and never needs to soak in a cup overnight. It simply becomes your teeth.
Often teeth in a day
Because four implants can carry a full arch, many patients leave the same visit with a fixed set of temporary teeth and walk out smiling.
Helps preserve your bone
Implants transmit the pressure of chewing into the jaw the way natural roots do, which helps maintain the bone that dentures leave to shrink over time.
Looks and feels natural
The final arch is custom-shaped and shaded to your face, so it reads as a real, healthy smile — not an appliance.
Fewer implants, one plan
Rather than an implant for every tooth, the full arch is anchored on four strategically angled posts — less surgery, one coordinated treatment.
Eat and live confidently
A stable bite means biting into an apple, sharing a meal, and laughing freely — without the guesswork of a removable plate.
One procedure, four steps.
Most of the transformation happens on a single day — the rest is healing while you already have teeth.

Plan in 3D
A CBCT scan maps your jaw and available bone in three dimensions. You and your provider review the plan and the expected result before anything begins.
- 02
Place four implants
Four titanium implants are positioned to anchor the arch — angled to capture the strongest bone and, in many cases, avoid the need for grafting.
- 03
Attach the arch
A fixed temporary arch is secured the same day in many cases, so you leave with teeth while everything heals underneath.
- 04
Fit your final teeth
Once the implants fuse to the bone over a few months, your custom, permanent arch is fitted — strong, natural, and built to last.
Why fixed beats removable.
Dentures replace the look of teeth. A fixed arch on implants replaces the teeth themselves — rooted, stable, and yours to keep. The difference shows up at every meal.

Told you don't have enough bone? Read this.
Many people are told over the years that they simply aren't candidates for implants — usually because past bone loss left too little to work with. The four-implant approach was designed with exactly that challenge in mind.
By angling the back implants, providers can often anchor a full arch in the denser bone you still have — frequently reducing or avoiding the need for grafting. Before you accept that implants aren't for you, it's worth a fresh 3D scan and a second opinion.
All-on-4, explained.
The questions patients ask most before taking the first step.
Talk to usWhat is All-on-4?
All-on-4 is a full-arch restoration that replaces an entire row of teeth using four dental implants as anchors for a single, fixed, non-removable set of teeth. Instead of placing an implant for every missing tooth, four implants carry the whole arch — restoring full chewing function and a natural appearance.
How is All-on-4 different from dentures?
Traditional dentures rest on the gums and are removable — they can slip, they rely on adhesives, and the bone beneath them tends to shrink over time. An All-on-4 arch is fixed to implants anchored in the jaw, so it stays put, transmits chewing forces into the bone to help preserve it, and feels far more like your own teeth.
How is it different from individual implants?
Replacing every missing tooth with its own implant can require eight, ten, or more implants and multiple procedures. All-on-4 restores a complete arch on just four implants, angled to use your available bone efficiently. That usually means less surgery, one coordinated treatment plan, and often a faster path to fixed teeth.
Can I really get teeth the same day?
In many cases, yes. Once the four implants are placed, a fixed temporary arch can be attached the same visit, so you leave with a complete smile. Your final, custom arch is fitted after the implants fully fuse with the bone — typically over a few months of healing.
Who is a candidate for All-on-4?
Most adults who are missing many or all of their teeth in an arch — or who are struggling with failing teeth, extensive decay, or loose dentures — are potential candidates. A provider confirms with a 3D scan and health review. Because the implants are angled to use existing bone, many people who were told they lacked enough bone for implants are still candidates.
What if I was told I do not have enough bone?
That is one of the reasons the four-implant approach was developed. By angling the back implants, providers can often anchor a full arch in denser available bone and reduce or avoid the need for bone grafting. It is always worth a scan and a second opinion before assuming implants are not an option for you.
