There are several different types of dental implants. Two of the more common varieties are endosteal and subperiosteal implants. Endosteal implants are placed squarely in the jawbone, and are the most common implant. Subperiosteal implants are used for those with a shallow jawbone, or in cases where the jawbone has deteriorated.
For patients who only need one tooth replaced, single-tooth implants are a better choice than a bridge because they preserve the overall health of the jawbone. Installing a dental bridge requires adjacent teeth to be ground down, weakening the strength of the jawbone. A single implant incorporates more naturally into your jawbone.
Maintaining your implants is relatively simple. In fact, the best way to preserve them is to treat them as regular teeth. A regular routing of brushing and flossing several times a day is the simplest and most effective way of preserving your implants. However, it is generally best to avoid chewing ice or other especially hard or chewy foods, such as chewing gum.
Bridges, dentures, crowns and implants are not the same thing. A crown is used to cover a decaying tooth and prevent further deterioration. Dental bridges, on the other hand are similar to implants in that they anchor a prosthetic tooth in place of a missing tooth to preserve the appearance of the mouth. Dentures are structures that can be removed at will that replace an entire arch of teeth.
These are all very different procedures. Implants use titanium posts to stabilize the crown into the jawbone; a bridge typically covers a broader area and is connected to the teeth on either end. If you are interested in tooth restoration, you will have to decide which approach is better for you.
