Dental Implant Bridge vs Traditional Bridge: What’s the Difference?
If you’re missing two or more teeth in a row, a bridge is one of the most common ways to fill the gap. But there are two very different ways to build one: a traditional bridge, anchored to your natural teeth, or an implant-supported bridge, anchored to implants placed in your jaw. They solve the same problem in different ways — here’s how they compare.
How a Traditional Bridge Works
A traditional bridge replaces one or more missing teeth by using the natural teeth on either side of the gap as anchors. Those teeth are shaved down to hold crowns, and a false tooth (or teeth) is fused between them, creating one connected unit that spans, or “bridges”, the gap.
How an Implant-Supported Bridge Works
An implant-supported bridge replaces multiple missing teeth using two or more implants placed at either end of the gap, rather than relying on your natural teeth. A fixed bridge then spans between the implants. This means the teeth either side of the gap — if you still have them — are left untouched.
Side-by-Side Comparison
| Implant-Supported Bridge | Traditional Bridge | |
|---|---|---|
| Anchored to | Implants placed in the jawbone | Natural teeth either side of the gap |
| Affects healthy teeth? | No | Yes — adjacent teeth are shaved down for crowns |
| Preserves jawbone? | Yes | No |
| Treatment time | Longer — requires healing/osseointegration time | Shorter — no healing period needed beforehand |
| Typical lifespan | 15+ years | 10–15 years |
| Best suited to | Several missing teeth in a row, especially where adjacent teeth are healthy | One or two missing teeth, or where adjacent teeth already need crowns |
Why Choose an Implant-Supported Bridge?
- Your remaining natural teeth aren’t cut down or weakened
- The implants stimulate the jawbone, helping prevent the bone loss that follows tooth loss
- Generally more stable under chewing forces than a bridge relying on natural teeth alone
- Tends to last longer, reducing the likelihood of remaking the bridge down the track
Why Choose a Traditional Bridge?
- No surgery or healing period required
- Can be completed in fewer visits
- Often a lower upfront cost
- May suit patients who aren’t candidates for implants due to bone volume or other health factors
How Many Implants Do I Need?
The number of implants required for a bridge depends on the size of the gap and the bite forces involved — a three-unit bridge might be supported by two implants at either end, while a longer span may need additional implants along the way. We’ll assess this using 3D imaging at your consultation and recommend the right number for a stable, long-lasting result.
Frequently Asked Questions
Is an implant-supported bridge more expensive than a traditional bridge?
Generally, yes, due to the surgical placement of implants — but it avoids ongoing costs from wear on the adjacent teeth and typically lasts longer, so the lifetime value is often comparable or better.
Do I need one implant per missing tooth?
No — an implant bridge usually needs fewer implants than the number of teeth being replaced, since the bridge spans between a smaller number of implant anchor points.
Can I get an implant bridge if I’ve already had a traditional bridge?
Often, yes. If a traditional bridge has failed or the supporting teeth are compromised, an implant-supported bridge can be a suitable replacement — we’ll assess your specific situation at a consultation.
