Losing multiple teeth — or facing full-arch tooth loss — is one of the most life-altering experiences a person can go through. Eating, speaking, and smiling all change. Traditional dentures solve some of that, but they can slip, require adhesives, and accelerate the jawbone loss that makes your face look older over time. All-on-4 dental implants offer a different path: a full arch of permanent, fixed teeth anchored by just four strategically placed implants. At Red Rock Oral and Facial Surgery in St. George, UT, our board-certified oral surgeons perform All-on-4 procedures for patients across Washington County and beyond — helping people in Washington, Hurricane, Ivins, Santa Clara, and Cedar City reclaim full, confident smiles.

What Are All-on-4 Dental Implants?

All-on-4 (also called “full-arch implants” or “teeth-in-a-day”) is a technique that replaces an entire upper or lower arch of teeth using only four dental implants as anchors. Unlike traditional implant placement — which typically requires one implant per missing tooth — All-on-4 uses two straight implants in the front of the jaw and two angled implants in the back. The angled rear implants take advantage of denser bone further forward in the jaw, which means most patients can proceed without the bone grafting that standard implant placement often requires.

The result is a full-arch prosthetic (a bridge of 10–14 teeth) that is permanently fixed to those four implants. You cannot remove it at night. It doesn’t slip or click. It functions and feels like natural teeth. For patients who have been living with dentures or significant tooth loss, the difference is profound.

How Is All-on-4 Different from Traditional Dental Implants?

If you’ve researched dental implants in St. George, UT, you know that the standard approach replaces individual teeth one at a time — each implant supports one crown. That’s ideal when you’re missing one or a few teeth. But when you’re missing most or all of your teeth, placing 12–16 individual implants is expensive, time-consuming, and often impossible for patients who’ve already experienced significant bone loss.

All-on-4 solves this by:

• Using only 4 implants per arch (upper, lower, or both)
• Angling the rear implants to access denser bone — often eliminating the need for bone grafts
• Delivering a temporary fixed prosthetic the same day as surgery (“teeth in a day”)
• Transitioning to a permanent prosthetic after osseointegration (healing, typically 3–6 months)

Are You a Candidate for All-on-4?

All-on-4 is not for everyone, but it’s a strong option for a wider range of patients than traditional implants because of how it handles bone density challenges. You may be a good candidate if you:

• Are missing all or most of your teeth in one or both arches
• Currently wear full or partial dentures and are unhappy with the fit or function
• Have been told you lack sufficient bone for traditional implants
• Are in good overall health and do not have uncontrolled diabetes or autoimmune conditions that impair healing
• Are a non-smoker, or are willing to quit smoking for the duration of treatment (smoking significantly increases implant failure risk)
• Have healthy enough gum tissue, or are willing to address gum disease before proceeding

Patients who still have many failing or infected teeth are also often good candidates — we may extract remaining teeth and place implants in the same procedure, minimizing your total number of appointments. Our surgeons serve patients throughout southern Utah, including those coming from Washington, Hurricane, Ivins, Santa Clara, and Cedar City who make the drive to St. George, UT for specialist-level care.

What Does the All-on-4 Procedure Look Like?

The All-on-4 process at Red Rock Oral and Facial Surgery in St. George, UT typically follows these stages:

1. Consultation and imaging: We use 3D cone-beam CT imaging to map your bone volume, nerve pathways, and anatomy in detail. This lets us plan exact implant placement before you ever get to the surgical chair.
2. Pre-surgical preparation: If any remaining teeth need to be extracted, we coordinate that with your implant day. We also evaluate and address any active infection or gum disease.
3. Surgery day: Under IV sedation or general anesthesia, we extract any failing teeth, place the four implants, and attach a temporary fixed prosthetic. Most patients leave our St. George, UT office the same day with a complete set of teeth.
4. Healing phase (3–6 months): The implants fuse with your jawbone in a process called osseointegration. During this time you wear the temporary prosthetic and follow a modified diet (softer foods).
5. Final prosthetic placement: Once osseointegration is confirmed, your permanent full-arch bridge is fabricated and attached. This is the restoration you’ll keep for decades.

How Much Do All-on-4 Dental Implants Cost in St. George, UT?

All-on-4 is a significant investment, but for patients replacing a full arch, it is almost always more cost-effective than placing individual implants for every tooth. In the St. George, UT area, patients can generally expect:

• Single arch (upper or lower): $20,000–$30,000
• Both arches: $35,000–$55,000

These figures include the surgical placement, the temporary prosthetic, and the final permanent prosthetic. They do not include pre-surgical extractions, bone grafts (if needed), or treatment for gum disease.

Dental insurance rarely covers implants fully, but medical insurance may cover a portion if tooth loss is related to a medical condition (such as oral cancer treatment). Flexible financing is available through our office. For a detailed breakdown of how implant costs work and how to make treatment affordable, see our post on dental implant cost in St. George, UT.

Frequently Asked Questions: All-on-4 Dental Implants in St. George, UT

How long do All-on-4 dental implants last?

The four implants themselves can last a lifetime with proper care and maintenance. The prosthetic (the arch of teeth) typically lasts 10–20 years before needing replacement, depending on material, bite forces, and how well you maintain oral hygiene.

Is the All-on-4 procedure painful?

The procedure is performed under IV sedation or general anesthesia, so patients feel no pain during surgery. Post-surgical discomfort is typically managed effectively with prescribed medications and generally resolves within 1–2 weeks.

How soon can I eat normally after All-on-4 surgery?

Most patients are on a soft or liquid diet for 6–8 weeks while osseointegration begins. After the final prosthetic is placed (typically 3–6 months post-surgery), you can return to a near-normal diet — though excessively hard foods like ice should be avoided.

Will I need bone grafting before All-on-4?

One of the major advantages of All-on-4 is that the angled rear implants access denser bone in the front of the jaw, which means many patients who don’t have enough bone for traditional implants can still receive All-on-4 without a prior bone graft. Your surgeon will determine this during your imaging and consultation appointment.

Does insurance cover All-on-4 dental implants?

Dental insurance rarely covers implants in full, though some plans cover a portion of the surgical fees. Medical insurance may apply if your tooth loss resulted from a covered medical condition. Our team at Red Rock Oral and Facial Surgery in St. George, UT can help you review your benefits and explore financing options.
