The principle

The principle is that the repair/connection is made with the aid of a bar that is held in place by screws and nuts (Fig.1). The thickness of the bar, and primarily the length, determines the stability of the fracture or connection.

A typical case is as follows: a bridge
    15 14    12 11   22    24 25
16         13        21    23
has fracture between 22 and 23.

(Fatigue fracture behind the first stable tooth.) The patient must clench his jaws so that the segments fall into place. Then, using a sticky wax or composite as buccal fixative, the fracture is fixed in the desired position (Fig.2).
