The old gold standard for replacing missing teeth was a fixed bridge. But, sometimes, one of the teeth supporting a fixed bridge can fail. In this case, a large space remains, leaving a person unable to chew on that side of the mouth. In this situation, two or more implants may be placed.
Although each tooth can be replaced individually by an implant, often people will opt for an implant supported bridge because it is less expensive. A bridge is defined as multiple crowns that are linked together.
In the case when multiple implants are placed, it is very common to utilize a surgical guide in order to precisely place the implants. Using a guide, often negates the need for grafting, decreases surgical time and further reduces discomfort that some may have from the procedure. Typically, there is very little discomfort associated with one, or multiple implants.
