Implant or bridge — which is the better long-term choice?

When a tooth is missing, two paths are essentially open: a bridge that rests on the neighbouring teeth, or an implant that is anchored independently in the jawbone. At first glance the decision looks like a pure cost question. On closer inspection it is, above all, a decision about the health of the neighbouring teeth.

The bridge — proven, but invasive

In a classic three-unit bridge, the two teeth neighbouring the gap are ground down all around to serve as abutments for the bridge framework. That means: two healthy teeth are sacrificed to replace one missing tooth. Bridges last on average 10 to 15 years. After that, the abutment teeth often have to be reworked a second time — and the remaining tooth structure shrinks further.

The implant — independent, bone-friendly

An implant is anchored directly in the jawbone and carries the crown itself. The neighbouring teeth remain untouched. A second, often underestimated effect: the implant transfers chewing forces to the bone and thereby prevents the bone loss that would otherwise inevitably occur in toothless areas.

Long-term economics

An implant is more expensive than a bridge in the initial investment. Looking at the lifespan, however — implants generally last decades, often a lifetime, with good care — the ratio reverses. Long-term studies show success rates of over 95 percent after ten years.

When is each solution right?

The bridge remains a valid option when:

• The jawbone is insufficient for an implant and bone augmentation is not desired
• The neighbouring teeth are already extensively restored (in which case nothing more is “sacrificed” by a bridge anyway)
• A timely restoration is urgently needed and the implant healing time is not feasible

In all other situations, the implant is the gentler, more bone-friendly and more economical choice in the long term.
