[BRACS--a method for cephalometric diagnosis and orthodontic treatment planning. Biometric radiographic analysis of the craniofacial skeleton].

The BRACS (the biometric radiographic analysis of the craniofacial skeleton) is a mathematically originated method for diagnosing malocclusion and planning orthodontic treatment. In the conventional cephalometrics, the measurements are to be made in an unstable reference frame without any definable direction or coordinate system. When using the BRACS, the natural reference structures can be replaced by an artificial stable reference system. The procedure is introduced in this paper.
