An implant-supported bridge, in theory, functions like a traditional bridge. The primary difference is how they are secured. A traditional bridge is supported and stabilized by the two adjacent teeth, where an implant-supported bridge is secured by attaching tiny titanium posts that are surgically embedded in your jawbone. The number of posts needed depends on the length of the bridge.
An implant supported bridge can indeed replace multiple teeth. One to eight posts can be implanted to support 2-14 artificial teeth on the bridge. Depending on the number of teeth you are missing, enough implants will be placed to successfully support the number in the bridge. Usually, two implants can support three to four teeth. Four to six implants will support an entire upper or lower arch of teeth.
The restoration is called either full mouth dental implants or an All on 4.
The Benefits of an Implant Supported Bridge
* It is a permanent restoration that remains fixed in your mouth.
* Biting, chewing, eating, and speaking will all be quite natural.
* The implants will not decay.
* It is easy to clean with a toothbrush, dental floss, and a water pick.
* The implants and artificial crowns will never have any nerve problems or need root canals.
* The titanium implant functions as an artificial root, stimulating the jawbone to maintain healthy density.
* Implants are even stronger than your natural teeth.
Different Implant Bridge Designs
Simple implant supported bridges usually replace a span of three to four teeth with implants placed at the far ends of the gap. Then the multiple tooth bridge is affixed to these implants. Other common designs include cantilever and front teeth implant bridges. There are several options.
* 3-4 Teeth Implant Bridge- It will be best for your dentist to place two implants on each side of the gap. The implants can be placed next to each other, but this will leave one side of the bridge unsupported.
* Cantilever Implant Bridges- Cantilever implant bridges are acceptable if the unsupported length is less than half the total length of the complete bridge.
Once the implants have fused and integrated to the bone, the bridge tray with the artificial crowns can be placed. Implant supported bridges cost less than individual implants simply because it takes fewer implants. A cantilever implant bridge might be the solution if there is not enough room to place multiple implants. There must be a minimum of 1 mm of jawbone in between each implant. If feasible, it is better to do individual implants and individual crowns. The more artificial roots ensure healthy gums and jawbone mass. Individual teeth will look even more natural and are much easier to clean.
Implant Supported Bridges vs. Traditional Dental Bridges
The most popular implant supported bridge contains three and four crowns which are secured by two implants and support spans of three to four artificial teeth. Implant supported bridges look more natural, function more like real teeth and will last decades. Implant supported bridges will not decay, develop cavities, or ever need a need root canal. Since the implants will never decay, implant supported bridges have an advantage over traditional bridges because the abutment teeth can always develop cavities and decay.
