What Are All-on-4 Dental Implants?
All-on-4 is a full-arch tooth replacement technique that uses four dental implants to support a fixed bridge or denture. Unlike traditional removable dentures, the restoration is secured to the implants and stays in the mouth permanently. It is designed to replace all the teeth on an upper or lower arch—or both—giving patients a stable, natural-looking smile.
At Alameda Dental, we provide this option for patients who have lost most or all of their teeth and are looking for an alternative that feels and functions more like natural teeth. Because only four implants are used per arch, the procedure can often be completed without the need for bone grafting, even when some bone loss has occurred.
How Do All-on-4 Implants Work?
Four titanium posts are surgically placed into the jawbone at precise angles. The two front implants are placed vertically, while the back implants are tilted to maximize contact with available bone and avoid anatomical structures such as sinuses or nerves. Over a healing period, the bone fuses to the implants in a process called osseointegration, creating a strong foundation.
Once the implants are stable, a custom-crafted, full-arch prosthesis is attached. The prosthesis is made from durable materials designed to withstand biting forces and mimic the appearance of natural gums and teeth. Because the restoration is fixed, it does not move during eating or speaking and does not require adhesives.
Are You a Candidate for All-on-4?
Ideal candidates for All-on-4 are individuals missing all or most of the teeth on an arch, or those who currently wear dentures and want a fixed solution. Patients with failing teeth that need to be removed may also be candidates. Good overall health and adequate bone volume are important, but the angled implant technique often allows us to treat patients who have experienced some bone loss without needing bone grafts.
During your consultation at Alameda Dental, we will take 3D images of your jaw and review your medical and dental history. We will discuss any factors that could affect healing, such as smoking or certain medical conditions, and help you understand whether All-on-4 is a suitable option. If it is not, we will explain alternative treatments.
The All-on-4 Treatment Journey
Your journey to a restored smile typically involves several steps:
- Treatment planning – Using digital planning software, we design the implant placement and the prosthesis, ensuring a precise fit and natural aesthetics.
- Surgery day – Under local anesthesia or sedation (if desired), we remove any remaining teeth, place the four implants, and attach a temporary fixed prosthesis. For many patients, this means leaving our office with functional teeth the same day.
- Healing period – Over the next several months, the implants fuse with the jawbone. You will wear the temporary teeth and follow a soft diet while monitoring healing.
- Final restoration – Once healing is complete, we take impressions and create your custom permanent prosthesis, which is then secured to the implants.
The exact timeline and details depend on your individual situation. We will review each phase with you before treatment begins.
Benefits and Considerations
All-on-4 offers meaningful advantages for those who qualify:
- A fixed, non-removable set of teeth that feel secure
- Restored ability to chew a wide variety of foods with confidence
- A natural-looking smile that is customized to your facial features
- Helps preserve jawbone density by stimulating the bone through the implants
- No need for messy denture adhesives
- Fewer implants required compared to placing a separate implant for every missing tooth
It is also important to understand the commitments. The procedure requires surgery and a healing period. While the implants themselves are designed to be permanent, the prosthetic teeth may need maintenance or replacement over time. Excellent oral hygiene and regular dental visits are essential to prevent complications such as peri-implantitis. Our team will provide detailed guidance on how to care for your new teeth and maximize their longevity.
Aftercare and Maintaining Your New Smile
After surgery, some swelling and mild discomfort are normal and typically subside within a few days. We will provide pain management recommendations and detailed aftercare instructions. A soft-food diet is necessary during the initial healing period to protect the implants.
Long-term care for All-on-4 implants is similar to caring for natural teeth—brushing, flossing around the implants, and attending regular checkups. We may recommend special cleaning tools like interdental brushes or water flossers to reach around the implants and under the prosthesis. Our team will show you the techniques that work best for your restoration.
If you ever notice looseness, discomfort, or signs of inflammation, contact us promptly. Early attention helps protect your investment.
Understanding the Cost of All-on-4
The cost of All-on-4 treatment varies based on several factors, including the number of arches treated, the materials selected for the prosthesis, and any necessary preparatory procedures such as extractions or bone grafting. During your consultation, we will provide a written treatment plan with a detailed breakdown of all fees.
We verify your dental insurance benefits and explain what your plan may cover. Our office also offers flexible payment options to help make treatment more affordable.
