What Are All-on-4 Implants?
All-on-4 is a full-arch tooth replacement method that uses four dental implants, small titanium posts placed in the jawbone, to support a complete set of fixed replacement teeth. Unlike a removable denture, the new arch attaches securely to the implants and doesn't come out for cleaning. Two of the four implants are usually angled toward the back of the jaw, which lets many patients with some bone loss avoid extra surgery. This technique falls under our broader restorative and surgical dentistry services, alongside our standard dental implants options for smaller gaps.
Benefits of All-on-4 Over Traditional Dentures
Patients choose All-on-4 for reasons that go beyond looks:
- No slipping or clicking. The arch is fixed in place, so there's no worry about it moving while you eat or speak.
- No messy adhesives. You won't need denture paste or overnight soaking.
- Helps preserve jawbone. The implants stimulate bone the way natural roots do, which may help slow the bone loss that follows tooth loss.
- Fewer implants needed. All-on-4 typically replaces a full arch with four implants instead of six or more, often meaning a shorter, more affordable path to fixed teeth.
- Real chewing power. Many patients find they can eat foods again that a loose denture made difficult, like apples or corn on the cob.
Am I a Candidate for All-on-4?
Good candidates are usually missing most or all of their teeth in an arch, or have teeth that are failing and likely to need extraction soon. You should be in reasonably good general health, since the procedure involves minor oral surgery. If you currently wear a full denture or dentures and partials and feel frustrated by the fit, All-on-4 is worth discussing at a consultation. Patients with more significant jawbone loss may still qualify; Dr. Isom will review your CBCT scan and let you know honestly whether bone grafting or a different approach makes more sense for you.
All-on-4 vs. Traditional Dentures & Partials
Here's how All-on-4 compares to traditional removable dentures on the things patients care about most:
| Feature | All-on-4 Implants | Traditional Dentures |
|---|---|---|
| Stability | Fixed in place, does not move | Can shift or slip, especially when eating |
| Bone preservation | Helps maintain jawbone through implant stimulation | Bone loss often continues over time |
| Daily maintenance | Brush like natural teeth, no removal needed | Requires removal, cleaning, and adhesive |
| Cost | Higher upfront investment | Lower upfront cost |
| Longevity | Designed to last many years with proper care | Often needs relining or replacing every several years |
Neither option is automatically better for every patient. Some people are happy with a well-fitted removable denture, while others want the fixed stability All-on-4 offers. Dr. Isom will help you weigh both honestly based on your bone health, budget, and goals.
The All-on-4 Treatment Process at Isom Dentistry
Every All-on-4 plan starts with a consultation and a CBCT 3D scan, so Dr. Isom can see your jawbone structure and map out implant placement before any surgery happens. If you still have teeth that need to come out, tooth extractions can often be done the same day as implant placement. From there, the process generally includes:
1. Placement of four implants into the jawbone.
2. Attachment of a temporary fixed arch, so you're rarely without teeth.
3. A healing period of a few months while the implants bond with the bone.
4. Placement of your final, custom-fitted replacement arch.
Dr. Isom walks you through timing and what to expect at each visit, so there are no surprises along the way.

FAQ
How long do All-on-4 implants last? ⌄
With good oral hygiene and regular checkups, All-on-4 implants are designed to last many years, and many patients keep them for decades. The replacement teeth may eventually need adjustment due to normal wear, but the implants themselves are built for the long term.
Is All-on-4 surgery painful? ⌄
Most patients report less discomfort than they expect, and sedation options are available to help you stay comfortable during the procedure. Some soreness and swelling afterward is normal and typically manageable with pain relief.
Does insurance cover All-on-4 implants? ⌄
Coverage varies by plan, but many PPO dental plans provide partial coverage for implant-related procedures. Our team accepts a broad range of PPO plans and will help you understand your benefits before you commit to treatment.
