All-on-X Dental Implants: How Full Arch Digital Dentistry Works and Differs from All-on-4

As a full-service dental clinic , North York Smile Centre offers All-on-X, a modern approach to replacing a full arch of missing or failing teeth with dental implants and a fixed prosthesis. It delivers the same life-changing result that made All-on-4 well known: permanent, natural-looking teeth placed on the day of surgery. The difference lies in how treatment is planned and produced. A fully digital workflow with in-house 3D printing improves efficiency while making All-on-X significantly more affordable, with savings of approximately $15,000 to $20,000 for many patients compared to traditional All-on-4 treatment fees in the Toronto area.

What Is All-on-X?

All-on-X is full-arch implant dentistry. An entire arch of teeth is replaced using strategically placed dental implants that support a fixed prosthesis. There are no removable dentures and no adhesives, just a smile that feels secure and natural.

The X in the name reflects flexibility. Instead of committing to a fixed number of implants for every patient, the number and position of implants are chosen individually based on your anatomy, bone volume, and treatment goals. Every case is planned digitally before surgery, so you can see the design of your new smile in advance.

Why Full Arch Treatment Matters

Complete tooth loss is becoming less common in Canada, yet it still affects a significant part of the population. According to the latest Canadian Health Measures Survey , about 3% of adults aged 20 to 79 and 8% of seniors aged 60 to 79 have no natural teeth. Behind these numbers are real consequences: untreated tooth loss can change eating patterns, limit food choices, affect speech, and undermine confidence in everyday life.

Many more people live with failing teeth, loose dentures, or chronic infection and put off treatment for years. If you are comparing tooth replacement options , full-arch implant dentistry is the closest modern dentistry comes to restoring your natural teeth.

From Traditional Implants to All-on-4 to All-on-X

Years ago, replacing an entire arch often required 8 to 10 implants, bone grafting, long healing times, multiple surgeries, and higher costs. The treatment was excellent but very involved.

Then came All-on-4, a major advancement. Using four strategically placed implants, many patients could receive fixed teeth the same day. Treatment became faster, more predictable, and more affordable. You can read how that procedure works step by step in our detailed guide to the All-on-4 procedure .

All-on-X takes things even further. At North York Smile Centre, a fully digital workflow allows the team to plan every case digitally, use CBCT and 3D scanning, design smiles before surgery, 3D print provisionals in-house, and deliver beautiful results more efficiently. For patients, this means less time, more precision, and better value.

“This is not just about replacing teeth. It is about restoring confidence, health, comfort, function, and quality of life. The one thing we hear from patients over and over again is that their only regret is not doing it sooner, ” says Dr. Robert Eisen , who leads full-arch implant treatment at North York Smile Centre.

All-on-4 vs All-on-6 vs All-on-X: What Is the Difference?

All three concepts solve the same problem: a full arch of fixed teeth supported by implants. The difference is in how the number of implants is decided.

All-on-4	All-on-6	All-on-X
Four implants per arch, with the back implants angled to maximize contact with available bone	Six implants per arch for additional support where bone volume allows	A flexible number of implants chosen for your anatomy after 3D diagnostics
Fixed protocol	Fixed protocol	Individually planned protocol built on a fully digital workflow
Fixed full arch teeth, often the same day	Fixed full arch teeth, often the same day	Fixed full arch teeth the same day, with provisionals 3D printed in-house

With All-on-X, the question is no longer which protocol you fit into. The 3D diagnostics show exactly where your bone is strongest, and the plan is built around you. For some patients, that means four implants; for others, five or six. The prosthesis, the same-day delivery, and the final result remain consistent.

The Fully Digital Workflow

The efficiency of All-on-X comes from technology that is used at every stage of treatment:

• CBCT: a 3D X-ray that shows all the details in your bone
• Intraoral scanner (iTero): a 3D scan that captures everything in your mouth
• Digital smile design: your new smile is designed before surgery
• In-house 3D printing: provisional prosthetics are fabricated right in the office

Because planning, design, and provisional fabrication happen under one roof, treatment requires fewer appointments and less outside laboratory work.

Why All-on-X Costs Less Than Traditional All-on-4 Treatment

Full-arch implant treatment is a significant investment. Published fees for All-on-4 treatment at clinics across the Toronto area commonly range from $20,000 to $50,000 per arch, depending on the clinic, materials, and case complexity.

All-on-X at North York Smile Centre starts at $19,995 per arch. The clinical solution is the same: hopeless teeth are removed, implants are placed, and a fixed prosthesis is fabricated and delivered on the same day. The savings come from the process. Digital planning reduces chair time and surprises, and in-house 3D printing removes a large share of traditional laboratory costs. For many patients, this means saving approximately $15,000 to $20,000 compared to traditional All-on-4 treatment, without compromising the result.

Many patients are surprised by affordability. With financing, monthly payments start at around $400 on approved credit.

Three Treatment Levels

Every patient is different, which is why North York Smile Centre offers three levels of All-on-X treatment:

	Essential	Core (Most Popular)	Premium
Price per arch	From $19,995	From $24,995	From $29,995
Monthly payments*	From $400/month	From $465/month	From $594/month
Restoration	PMMA Hybrid Restoration	Titanium-reinforced restoration for greater durability	Full Zirconia, premium ceramic restoration
Included	Digital planning, comprehensive exam, CBCT, and in-house printed provisional	Everything in Essential plus same-day provisional and digital try-in	Highest aesthetics, most durable material, designed for maximum longevity

*Monthly payments are available on approved credit. Final fees are confirmed after your consultation and 3D diagnostics, since every case is individual.

The levels differ mainly in the material of the final restoration. Essential uses a PMMA hybrid restoration, a proven solution for straightforward cases. Core adds a titanium-reinforced restoration for greater durability, along with a same-day provisional and a digital try-in. Premium uses full zirconia, a premium ceramic that offers the highest aesthetics and is the most durable, designed for maximum longevity.

How Long Do Full Arch Implants Last?

Full-arch implant treatment is one of the best-documented solutions in modern dentistry. A longitudinal study following patients for 10 to 18 years reported a 98.8% prosthetic survival rate and a 93% cumulative implant survival rate for the full-arch treatment concept. With proper home care and regular professional visits, your fixed teeth are designed to serve you for decades.

Your All-on-X Journey

Treatment follows a clear path from the first visit to the final smile:

• Consultation: your goals, health history, and options are reviewed
• 3D scan and CBCT: complete digital records of your mouth and bone
• Digital planning: implant positions and your new smile are designed in advance
• Surgery: failing teeth are removed, and implants are placed, with IV sedation available for comfort
• Same-day teeth: a fixed provisional prosthesis is attached, so you never go without teeth
• Healing: The implants integrate with your bone
• Final smile: your permanent restoration is delivered

The surgical team, digital technology, 3D printing, and restorative care are all under one roof, with collaborative care at every step.

Who Is a Candidate for All-on-X?

All-on-X may be the right solution if you avoid smiling or hide your teeth in photos, have loose or uncomfortable dentures, avoid certain foods, have teeth that are breaking down, or feel embarrassed about your smile.

“Patients often assume they are too old for treatment or that bone loss rules them out. In many cases, it does not. Digital planning lets us position implants where the bone is strongest, and the only way to know what is possible is a proper assessment with 3D imaging,” explains Dr. Jerry Jesin .

If you are new to the clinic, our team of dentists in North York who are accepting new patients will guide you through your first visit, your medical history, and your options, with no pressure and no obligation.

Frequently Asked Questions

Is All-on-X the same as All-on-4?

The result is the same: a fixed full arch of teeth supported by implants and placed the same day. The difference is flexibility and process. All-on-X does not fix the number of implants in advance, and the fully digital workflow with in-house 3D printing makes treatment faster and more affordable.

How much does All-on-X cost?

At North York Smile Centre, All-on-X starts at $19,995 per arch for the Essential level, $24,995 for the Core level, and $29,995 for the Premium level, with a full zirconia restoration. Financing is available with monthly payments starting around $400 on approved credit.

Does the surgery hurt?

Treatment is performed with anesthesia, and IV sedation is available. Most patients are far more comfortable than they expected.

Am I too old for All-on-X?

Age by itself is not a barrier. Candidacy depends on your health and your bone, which is exactly what the consultation and CBCT scan assess.

What if I have bone loss?

Bone loss does not automatically rule out treatment. Digital planning allows implants to be positioned where your bone is strongest. Your 3D scan will show what is possible in your case.

How long does treatment take?

You receive fixed provisional teeth on the day of surgery, so you never go without teeth. The final restoration is delivered after your implants have healed and integrated with the bone. The exact timeline is individual and is confirmed at your consultation.

What if I already wear dentures?

Many All-on-X patients come to us with loose or uncomfortable dentures. All-on-X replaces removable dentures with fixed teeth that do not slip or require adhesives.

How do I care for my new teeth?

Care is similar to that for natural teeth: daily home hygiene and regular professional visits. Your team will give you exact instructions after treatment.
