How Many Teeth Does an Implant-Supported Bridge Have?
An implant-supported bridge is a tooth replacement option that provides a strong, durable solution to replace multiple missing teeth. The number of implants needed to support the bridge replacement depends on the size of the bridge and the number of teeth being replaced. During the procedure, implants are placed in the jawbone to support the bridge. In general, 2 implants can replace 3-4 missing teeth. Below is more information on the number of teeth involved in a dental implant bridge procedure.
How Many Teeth Are in an Implant Supported Bridge
In general, a common implant bridge usually replaces 3-4 missing teeth. The bridge is attached to titanium implants placed in the jawbone at the ends of the missing teeth span. There are various bridge designs and countless options to replace missing teeth. Here are a few of the most common options:
- Conventional 3-4 Tooth Implant Bridge: A common 3-4 tooth bridge requires two dental implants placed on either side of the missing tooth space. The implants can also be placed next to one another, depending on where the teeth are missing and what the dental provider decides is the best supporting option.
- Cantilever Implant Bridge: A cantilever bridge is another option that works when the unsupported bridge length is less than 1/2 the overall length of the supported prosthetic section. A common cantilever design is when one implant supports 2 replacement tooth crowns. This approach is more cost-effective than replacing two teeth with two dental implants, or may be necessary when there is not enough room to install multiple implants.
- Front Teeth Implant Bridge: To replace missing front teeth and restore the smile’s appearance, it is common to use two implants, two abutments, and a four-unit implant bridge. The most ideal option is to use zirconia implants because they are tooth-colored, metal-free, and the best cosmetic option for improving the appearance of the smile.
- Replacing a Full Set of Teeth: To fully replace a set of teeth with implant-supported bridges, a dentist may opt for an approach where 4-6 implants permanently replace a full upper or lower set of teeth. The procedure can be expensive and involved, but full-teeth implant bridges are a more durable and permanent option for most people over removable dentures that attach to implants. In general, the ideal approach is individual implants with individual crowns, which retain the root structure and help preserve the gum and bone. Aesthetically, individual teeth look more natural and are easier to clean.
What Does an Implant Supported Bridge Cost?
Overall, the cost of an implant-supported bridge can vary widely and depends on how many teeth the bridge is replacing and how many implants are required. The total treatment cost includes removing any teeth, installing dental implants, and building the bridge. Sometimes the cost of installing dental implants will be higher if the patient needs additional bone grafting and IV sedation.
