All-on-4® & Full Arch Dental Implants in St. Cloud
Restore Your Smile with Permanent Full-Arch Teeth
All-on-4 dental implants are a revolutionary restorative solution designed to replace an entire upper or lower arch of missing teeth using only four strategically placed titanium implants. Unlike traditional dentures that rest on the gums, All-on-4 is a permanent, fixed prosthetic that functions like natural teeth. At Centrasota Dental, we combine the specialized engineering of a Prosthodontist with advanced 3D imaging to provide life-changing full-arch restorations that look, feel, and function like the real thing.
What is All-on-4® Full Arch Treatment?
The All-on-4 technique is a surgical and restorative procedure that provides a permanent alternative to loose dentures. By tilting the posterior (back) implants at a 45-degree angle, we can maximize existing bone density, often eliminating the need for invasive bone grafting. This “bridge” of teeth is screwed directly into the implants, making it stable and non-removable by the patient.
All-on-4 vs. Traditional Dentures
Traditional dentures rely on suction or adhesives and often slip, causing discomfort and limiting your diet. More importantly, dentures do not stop bone loss. All-on-4 implants act as artificial tooth roots, stimulating the jawbone to prevent bone resorption. Because the prosthetic does not cover the roof of your mouth (palate), you can taste your food better and speak more naturally.
Teeth-in-a-Day: The “New Smile” Experience
Teeth-in-a-Day is a procedure where we place the dental implants and attach a functional, aesthetic temporary bridge during the same visit. This means you walk into our St. Cloud office with missing teeth or failing dentures and walk out with a complete, beautiful smile. While these temporary teeth are replaced with your final porcelain restoration after healing, you are never without a smile during the process.

The Recovery & Healing Timeline
Recovery from All-on-4 surgery is faster than many expect, though total healing occurs in phases. Most patients return to work within 2 to 3 days. However, the biological process of osseointegration (bone fusing to the implants) takes 3 to 6 months. During this time, you will follow a “soft-food” diet to ensure the implants are not disturbed while they bond to your jawbone.
Cleaning and Maintenance
Caring for a full-arch bridge is simple but essential for long-term success. Because the bridge is fixed, you brush it just like natural teeth. To clean underneath the bridge where it meets the gums, we recommend using a water flosser (Waterpik) or specialized floss threaders. Regular professional cleanings at Centrasota Dental are required twice a year to ensure the health of the surrounding gum tissue.
Temporary vs. Permanent Restorations
On the day of surgery, you receive a “Temporary Bridge.” This is made of a high-quality acrylic and serves as a blueprint for your permanent teeth. Once your jaw has fully healed (approx. 6 months), Dr. Congdon will design your “Final Restoration.” These permanent teeth are typically made of Zirconia or high-grade porcelain, which offer superior durability, stain resistance, and a lifelike translucency.
All-on-6 Implant Options
While All-on-4 is the standard, some patients with lower bone density or higher biting forces may benefit from All-on-6. This involves placing two additional implants to provide even greater stability and distribution of pressure. During your 3D CT scan, Dr. Congdon will determine which configuration is best suited for your unique anatomy.
Cost of Full Arch Implants in MN
The cost of All-on-4 in Minnesota varies based on the materials used (Zirconia vs. Acrylic) and the complexity of the case. While the initial investment is higher than dentures, All-on-4 is a long-term investment that prevents future bone loss and costly denture replacements. We provide a full transparent quote during your consultation and offer flexible financing to make a permanent smile attainable.
Full Arch / All-on-4 FAQ
Can I eat steak with All-on-4?
Yes! One of the biggest benefits of a full-arch implant restoration is the return of nearly 100% of your natural biting force. Once your permanent bridge is placed and the bone is fully healed, you can enjoy steak, apples, corn on the cob, and other tough-to-chew foods that are impossible to eat with traditional dentures.
How do I clean under the bridge if it’s not removable?
Cleaning under the bridge is vital to prevent “peri-implantitis.” We recommend using a water flosser on a medium setting twice a day to flush out food particles. You can also use “Superfloss” or interdental brushes designed to slide into the small space between the bridge and the gum line.
Is the bridge removable?
No. All-on-4 is a “fixed” restoration, meaning it is screwed into the implants and can only be removed by a dentist. This provides the security and confidence of natural teeth—you never have to worry about your teeth falling out or being placed in a glass at night.
How much does All-on-4 cost in Minnesota?
In the MN area, full-arch restorations typically range from $18,000 to $30,000 per arch. The price depends on whether you choose All-on-4 or All-on-6, and the material of the final teeth. We provide a detailed breakdown of costs, including surgical and restorative fees, during your consult.
Does insurance cover full-arch implants?
Most dental insurance plans provide a lifetime maximum that can be applied to the bridge or the implants. While they rarely cover the entire cost, our team will work with your provider to maximize your benefits. Many patients also use FSA/HSA funds or healthcare financing like CareCredit.
What is the total recovery time?
Initial surgical healing takes about 7 to 10 days, during which you may experience minor swelling. However, the “functional” recovery (the time it takes for the implants to fuse to the bone) is 3 to 6 months. During this healing phase, you will wear your temporary bridge and stick to a softer diet.
How long will I be without teeth?
Zero days. Thanks to the “Teeth-in-a-Day” protocol, we ensure that you are never without teeth. Your temporary bridge is attached immediately after the implants are placed, so you walk out of our office with a complete smile on the very same day.
How is All-on-4 different from Snap-on dentures?
Snap-on dentures (Overdentures) are still removable and often involve a palate (the roof of the mouth). They “snap” onto 2-4 implants but can still shift slightly. All-on-4 is fixed, does not cover the palate, and provides significantly more biting power and stability than a snap-on.
What materials are used for the permanent bridge?
We offer two primary materials: Monolithic Zirconia and Porcelain fused to a Titanium frame. Zirconia is the most popular choice because it is virtually unbreakable, highly resistant to staining, and can be customized to look incredibly natural.
Is the full-arch surgery painful?
Most patients are pleasantly surprised by how comfortable they are. Because we use local anesthesia and offer IV sedation, you will not feel anything during the procedure. Post-operative discomfort is usually managed with prescription-strength ibuprofen and is often described as a “pressure” rather than sharp pain.
Choosing an Expert for Your Full-Arch Transformation
Full-arch restoration is as much an engineering feat as it is a dental procedure. As a Prosthodontist, Dr. Robert Congdon specializes in the complex “smile architecture” required for All-on-4. From the precision of the 3D planning to the artistry of the final porcelain teeth, our team ensures your new smile is built to last a lifetime.
