One detail that surprises some patients researching All-on-4 is that the "teeth in a day" you may leave surgery with aren't your final teeth. There are two distinct restorations involved in the process — the temporary (which your surgeon may call a provisional prosthesis) and the final — and understanding the difference helps set the right expectations from the start.
All-on-4 implants need time to fuse with your jawbone through a process called osseointegration — typically 3 to 6 months. During that healing window, your bite, gum tissue, and jaw are still settling into their final position. Placing your permanent, most durable restoration before that process completes would mean building it around measurements that are still changing.
The solution: a temporary prosthesis that lets you eat, speak, and live normally during healing, followed by a final prosthesis built once everything has stabilized.
When it's placed: Often the same day as implant surgery, if adequate implant stability is achieved (this is what "same-day teeth" or "teeth in a day" refers to). In some cases, a short healing period is needed first.
What it's made from: Typically a lighter-weight, more easily adjustable material — often PMMA acrylic.
What it's for:
What to expect: The temporary bridge functions well for normal soft-food eating but isn't meant for hard or sticky foods (nuts, ice, crusty bread, tough steak) during the healing period. It's fully functional, just not built for the same long-term durability as the final version.
When it's placed: Typically 3–6 months after surgery, once your surgeon confirms the implants have fully integrated with the bone.
What it's made from: A more durable, longer-lasting material — commonly zirconia or nano ceramic composite, chosen based on your bite, aesthetic goals, and budget. See our cost guide for a full comparison of prosthetic materials.
What it involves: New impressions or digital scans are taken once healing is complete, allowing your dentist to fabricate a restoration precisely matched to your now-stable bite and gum position — along with any refinements to fit or aesthetics based on how the temporary phase went.
What to expect: This restoration is built for long-term daily use and is generally more wear-resistant, stain-resistant, and durable than the temporary version.
| Factor | Temporary Prosthesis | Final Prosthesis |
|---|---|---|
| Timing | Day of surgery (or shortly after) | 3–6 months post-surgery |
| Common material | PMMA acrylic | Zirconia or nano ceramic |
| Durability | Lower — designed for healing phase | Higher — designed for long-term use |
| Diet restrictions | Soft foods recommended | Closer to normal diet once fitted |
| Purpose | Function + healing protection | Long-term daily restoration |
No — even in ideal cases with excellent implant stability, some healing period is medically necessary before the final restoration can be accurately fabricated and fitted. The temporary phase isn't a delay tactic; it's a required part of a process built around how bone actually heals.
Since both restorations are part of a complete All-on-4 treatment, confirm with your provider:
Quotes that don't clearly separate these two components are one of the more common sources of confusion (and unexpected cost) patients run into. Our cost and financing guide breaks down what a comprehensive quote should include.
