Occlusal plane analysis using the Broadrick flag.

The determination of the occlusal plane can have a profound effect on the short- and long-term success of a restorative case. The fewer posterior interferences that result from the reconstruction means fewer problems for patients with their teeth, muscles, and temporomandibular joints. Proper utilization of the Broadrick flag on a semi-adjustable articulator will allow the dentist or laboratory technician to easily determine the ideal plane for each case. As mentioned earlier, the use of Monson's theory is only a starting point for the analysis. Patients come in different shapes and sizes and sometimes have mandibular incisors that are not positioned ideally. With a little experience and training, dentists can make the Broadrick flag an integral part of their practice. The Broadrick flag now has been adapted to several articulator systems, including Hanau (all models), Denar, Jensen (Artex--under development), and Kavo (Protar).
