An implant-supported bridge replaces multiple missing teeth with a prosthesis anchored to implants rather than to adjacent natural teeth. Several configurations exist, each with specific indications.
1. Three-Unit Implant Bridge
Two implants support a bridge of three teeth — one pontic (fake tooth) suspended between two implant-supported crowns. The classic indication is three missing teeth in a row where placing an implant for the middle tooth is not ideal anatomically.
2. Long-Span Implant Bridge
More than three teeth replaced on two or more implants. Requires careful biomechanical design — too many pontics between implants stresses the bridge and its supporting components.
3. Full-Arch Fixed Bridge (All-on-4 / All-on-6)
An entire arch of teeth — 10 to 14 — supported on four to six implants. See our dedicated All-on-4 page and the STAR Concept™ for our next-generation protocol.
4. Screw-Retained vs. Cement-Retained
Screw-retained bridges attach to implants via access holes sealed with composite. They are fully retrievable — we can remove the bridge for maintenance or repair without destroying it. Cement-retained bridges are bonded in place with dental cement; they are not retrievable and carry a risk of subgingival cement left behind, which can cause peri-implantitis. For full-arch and long-span cases, screw-retained is almost always the better choice.
5. Hybrid (Acrylic-on-Titanium)
A titanium substructure with acrylic teeth and pink acrylic gum tissue bonded on. Historically the standard full-arch design. Relatively inexpensive but subject to wear and occasional tooth fractures that require repair.
6. Monolithic Zirconia
The entire bridge milled from a single block of zirconia ceramic. Extraordinarily durable, aesthetically superior, resistant to staining and wear. More expensive than hybrid acrylic but frequently the right long-term investment. Our STAR Concept™ final prostheses are typically monolithic zirconia.
7. Porcelain-Fused-to-Metal (PFM)
An older but still-used option. A metal substructure with porcelain layered on top. Strong but less aesthetically refined than zirconia and subject to porcelain chipping.
