A dental appliance for treating bruxism is disclosed. The appliance may include upper and lower portions. The upper portion may comprise a first base and a first feature. The first base may engage the upper teeth of a patient. The first feature may secure to an anterior area of the first base and comprise a concave surface forming a concavity. The lower portion may comprise a second base and a second feature. The second base may engage the lower teeth of the patient. The second feature may secure to an anterior area of the second base and comprise a protrusion. As the patient bites down, the protrusion may contact the concave surface at a point of contact that is a sole or initial contact between the upper and lower portions. Thus, the interaction of the protrusion and concave surface may control certain mandibular loadings and motions of the patient.
