All-on-4 Dental Implants in Brentwood: Full Arch Replacement Explained

Losing most or all of your teeth changes more than just your smile. It changes how you eat, how you speak, and honestly, how comfortable you feel in a room full of people. For a long time, the only real fix was dentures. They worked, but not perfectly. They shifted, clicked, and needed to come out at night.

All-on-4 dental implants changed that. This treatment gives patients a full arch of fixed, natural-looking teeth supported by just four implants placed directly into the jawbone. No removal. No adhesive. No embarrassing moments at the dinner table.

If you’ve been searching for full arch implants near me or looking into dental implants in Brentwood, this guide covers everything you need to know before booking a consultation at Arbor Family Dentistry.

Quick Facts: All-on-4 Dental Implants

What Are All-on-4 Dental Implants?

The name is straightforward. Four titanium implants are placed into your jawbone and used as anchors for a full arch of prosthetic teeth. That’s it at the core level.

What makes it work so well is the angle of placement. The two rear implants are tilted at roughly 30 to 45 degrees rather than going in straight. That angle gives them access to denser bone further back in the jaw, which means they can skip bone grafting in most cases. The result is a stable, load-bearing foundation built from just four points of contact.

This is very different from a single-tooth implant, which replaces one tooth with a single post. It’s also different from traditional full-arch individual implants, where you might need six to eight posts per arch. All-on-4 is specifically designed to efficiently replace an entire arch using the bone you already have.

It works for both the upper and lower jaw. Some patients need just one arch replaced. Others need both. Either way, the mechanics are the same.

Who Is a Good Candidate?

The ideal All-on-4 patient is someone dealing with major tooth loss. That could mean several missing teeth, a failing dentition that’s heading toward full extraction, or someone already wearing dentures who wants a permanent alternative.

Patients with bone loss are often surprised to learn they may still qualify. Because of the angled rear implants, All-on-4 typically doesn’t require bone grafting even in cases where traditional implants would. The American Academy of Implant Dentistry notes that this makes All-on-4 accessible to a wider range of patients than many people expect.

Good candidates generally:

• Are missing most or all teeth on one or both arches
• Have enough bone density to support four implants (assessed through CBCT imaging)
• Are non-smokers or willing to quit before surgery
• Have well-controlled health conditions like diabetes
• We are committed to the healing process and long-term maintenance

There are cases where All-on-4 isn’t the right fit. Active, uncontrolled periodontal disease needs to be treated first. Heavy smokers face a higher implant failure risk. Patients with severe, unmanaged systemic conditions may need medical clearance before any surgical implant work. A thorough consultation will flag any of these issues early.

How the All-on-4 Procedure Works

Step 1: Initial Consultation and 3D Imaging

The process starts with a full clinical evaluation. Digital X-rays and a CBCT (cone beam computed tomography) scan are taken to map your jawbone in three dimensions. This gives the dentist a precise picture of bone volume, density, and nerve location before a single incision is made. Treatment planning is built entirely around this data.

Step 2: Extraction (If Needed)

If you still have teeth that need to be extracted, extractions can often be done the same day as implant placement. There’s no need to wait months with no teeth. Everything is coordinated so the surgical appointment covers extraction and implant placement in one visit.

Step 3: Implant Placement

Four titanium posts are placed into the jawbone. The two front implants go in at a vertical angle. The two rear implants are placed at an angle to maximize contact with the available bone. Titanium is used because it fuses with bone over time through a process called osseointegration, which makes the whole thing stable in the long term.

Step 4: Temporary Arch Fitted Same Day

This is the part patients appreciate most. Before you leave the clinic, a temporary prosthetic arch is attached to the implants. It looks like a full set of teeth. You go home with teeth. You’re not waiting months with gaps in between.

The temporary arch is designed to be functional, but it’s not the final product. It lets the implants heal without being overloaded while still giving you something comfortable and presentable to wear.

Step 5: Healing and Osseointegration

Over the next three to six months, the titanium posts bond with your jawbone at a cellular level. This is osseointegration, and it’s what separates implants from every other tooth replacement option. During this phase, you’ll follow a soft-food diet and attend follow-up visits to monitor healing. 

Step 6: Final Permanent Arch Placed

Once healing is confirmed, the temporary arch comes off, and your custom-fabricated permanent arch is fitted. This is typically made from zirconia or high-grade porcelain. It’s shaped and shaded to look like natural teeth, fits precisely, and is built to last decades.

All-on-4 vs Traditional Dentures

Dentures sit on top of the gum. They don’t interact with the jawbone, so bone resorption continues over time. That’s why long-term denture wearers often develop that sunken facial look around the jaw and cheeks. All-on-4 implants go into the bone and stimulate it the same way natural tooth roots do, which stops that process.

All-on-4 vs Full Mouth Implants

Full-mouth reconstruction with individual implants typically requires 6 to 8 posts per arch. More posts mean more surgical sites, longer procedures, higher costs, and, in many cases,s a greater need for bone grafting.

All-on-4 achieves similar results with fewer implants. That makes it faster, less invasive, and more accessible from a cost standpoint. For most patients who need a full-arch replacement, All-on-4 is the more practical option.

That said, individual implants do have advantages in specific cases. If you’re replacing a partial arch or want to restore a few isolated teeth, single implants are usually the better choice.

What Does All-on-4 Cost in Brentwood?

Cost varies based on several factors: whether you need one arch or two, what materials are used for the final prosthesis, whether extractions are required, and the complexity of your individual case. There’s no honest one-size answer here.

What you can expect is that All-on-4 is an investment. It’s also a long-term one. When you factor in that traditional dentures need replacement every five to eight years and come with ongoing adhesive costs, follow-up adjustments, and the progressive bone loss that eventually requires more dental work, the gap between All-on-4 and dentures narrows considerably over a decade.

Most dental insurance plans don’t cover implants. However, FSA and HSA funds can be applied toward treatment, and flexible financing options are available to spread costs over time. Ask our team about current financing arrangements when you book your consultation.

Choosing a provider based on price alone is a risk worth mentioning. Implant success depends heavily on the skill of placement, the quality of materials, and the thoroughness of imaging done before surgery. A lower upfront cost that leads to implant failure ends up costing far more in the long run.

Frequently Asked Questions About All-on-4 Implants

1. How long do All-on-4 implants last?

With proper oral hygiene and regular dental visits, All-on-4 implants can last 20 years or more. The titanium posts themselves are often permanent. The prosthetic arch may eventually need to be replaced, but the implant foundation tends to hold.

2. Is the All-on-4 procedure painful?

The surgery is done under local anesthesia, and sedation options are available. Most patients report mild to moderate soreness in the days following surgery, managed with prescribed or over-the-counter pain relief. Discomfort is typically well-controlled and short-lived.

3. Can I eat normally with All-on-4 implants?

After full healing, yes. You get back most of your chewing strength. During the osseointegration phase, you’ll stick to soft foods, but that’s a temporary window.

4. How soon can I go back to work after surgery?

Many patients return to desk work within two to three days. If your job involves physical labor, you may need a longer recovery. Your dentist will give you a specific timeline based on how the surgery goes.

5. Do All-on-4 implants look natural?

Yes. The final zirconia or porcelain arch is custom-shaded and shaped to match your facial structure. Most people won’t be able to tell the difference.

6. Can All-on-4 be done in one day?

The implant placement and temporary arch happen in one appointment. The full process from consultation to final arch takes several months because of the healing phase required between placement and the final prosthesis.
