Metal-ceramic bridges have the longest track record (90% survival after 15 years). Zirconia bridges show comparable results in recent studies. Poor oral hygiene halves the life expectancy. Smoking increases the risk of failure by 30-40%. An annual check of the screw connections extends the lifespan. Ceramic fractures (2-5%) can be repaired with composite. Implant failure (1-3% per decade) requires replacement. Gum recession may make an aesthetic revision necessary after 10+ years. Modern materials and techniques aim for 25+ years of function.

How long does a partial implant-supported bridge last?
On average 15-20 years with good maintenance and a healthy mouth.
