IMPLANT SUPPORTED BRIDGE.

The above image demonstrates how an edentulous area or area with no teeth can be restored with an implant supported bridge.

This technique can be used to restore areas with multiple missing teeth without disturbing or placing too much force on the teeth on either side of the area. The "Law of Beams" states that as distance between abutments doubles, deflection of the bridge becomes the cube of it's previous movement under a given force. This procedure will also help retain the bone in this area since it will have a function.
An implant supported bridge can also be placed on a natural tooth if the movement of the tooth is less than 30 microns, which is the thickness of a strand of hair.

Again, the angulation, length and width of the implants are very important to ensure success. The design of the bridge needs to allow for proper oral hygiene for the patient.
