Anterior Bite Plane

An anterior bite plane is an appliance that has no posterior occlusion. The concept of this appliance is to separate the posterior teeth to help decrease muscle activity during clenching and grinding. Since there is no posterior occlusion, the lateral pterygoid is able to release and allows the condyle to seat.

Although there are different kinds of anterior bite planes, all the appliances are conceptually the same relative to the lack of posterior occlusion.
