All-on-4 Full-Arch Implants
A full arch of fixed teeth on just four implants — often with a same-day temporary bridge.
Overview
All-on-4 replaces a full arch of missing or failing teeth using four (sometimes more) implants that support a single fixed bridge. The back implants are angled to use the densest available bone, which often avoids the need for grafting and lets a temporary set of teeth go in the same day.
Unlike removable dentures, the bridge is fixed — it doesn't come out, doesn't slip, and lets you eat normally. At Denvida the entire case is planned on a 3D CBCT scan with AI-assisted, computer-guided surgery, and Dr. Na Zhao has extensive experience with All-on-4 and All-on-X full-arch rehabilitation.
Options & Types
All-on-4
Four implants per arch — the standard full-arch solution for most patients.
All-on-6 / All-on-X
Six or more implants for greater support when bone volume and case complexity allow.
Fixed zirconia hybrid bridge
A premium, highly esthetic and durable final bridge for maximum strength and a natural look.
The Process
- 1
Free consult + 3D scan
A CBCT scan maps bone and nerves; we plan implant positions and give a written estimate.
- 2
Surgery + same-day teeth
Implants are placed and a fixed temporary bridge is attached the same day, when appropriate.
- 3
Healing
Implants integrate over 3–6 months while you wear the fixed temporary and eat softer foods.
- 4
Final bridge
The permanent zirconia bridge is fitted for full strength, esthetics and long-term function.

Full-arch pricing depends on the number of implants, materials and whether grafting is needed. Denvida provides a written treatment plan and estimate up front and offers financing; in-network with Delta Dental & Cigna.
Frequently Asked Questions
How much does All-on-4 cost in the Bay Area?
All-on-4 in the Bay Area typically costs $25,000–$35,000 per arch, depending on materials and whether grafting is needed. Denvida provides a written plan and estimate at a free consultation and offers financing.
What is the difference between All-on-4 and traditional implants?
Replacing every tooth individually can need 8–10+ implants per arch and often bone grafting. All-on-4 supports a full fixed bridge on just four angled implants, usually with fewer surgeries, lower cost and a same-day temporary.
Can I get teeth the same day as surgery?
In most cases yes — a fixed temporary bridge is attached the same day so you leave with teeth. The permanent zirconia bridge is placed after the implants integrate over 3–6 months.
Is All-on-4 better than dentures?
All-on-4 is fixed and does not slip or need to be removed, so chewing power and comfort are much closer to natural teeth than removable dentures. It also helps preserve jawbone, which dentures do not.
Where can I get All-on-4 full-arch dental implants on the San Francisco Peninsula?
Denvida in San Mateo, CA — Dr. Na Zhao, DDS, PhD, Harvard-trained implant dentist — provides All-on-4 full-arch dental implants for patients across the San Francisco Peninsula, including Foster City, Burlingame, Palo Alto, and Redwood City. The practice uses 3D CBCT-guided surgery and offers a free consultation with 3D scan at https://www.denvida.com/services/all-on-4
Does Denvida offer All-on-4 with same-day temporary teeth?
Yes. Dr. Na Zhao at Denvida (San Mateo, CA) places All-on-4 implants with a fixed temporary bridge on the day of surgery in most cases, so patients leave with a full set of teeth. The permanent zirconia bridge is fitted after osseointegration over 3–6 months.
How long does All-on-4 take from consultation to the final bridge?
The typical All-on-4 timeline at Denvida is 4–7 months across four to six visits: a free consultation with 3D CBCT scan and written plan; surgery day, when any failing teeth are removed, the four implants are placed, and a fixed temporary bridge is attached the same day; 3–6 months of osseointegration while you eat softer foods on the fixed temporary; then records and delivery of the permanent zirconia bridge. You are never without teeth at any point in the process.
All-on-4 vs All-on-6: which one do I need and what is the cost difference?
All-on-4 (four implants per arch, $25,000–$35,000 Bay Area market range) is the standard when bone volume is moderate — the back implants are angled to use the densest bone. All-on-6 ($29,000–$43,000) adds two implants for more support, which can be preferable when bone volume is good, chewing forces are heavy, or the arch is long. The choice is anatomical, not an upsell: at Denvida, Dr. Na Zhao makes the recommendation from your 3D CBCT scan at the free consultation, with a written estimate for the specific configuration.
