According to one embodiment, an apparatus may include a first arched frame and a second arched frame. The first arched frame may include an adjustment mechanism and may be configured to be positioned proximate to the occlusal surface of a user's mandibular arch such that the first arched frame extends beyond the lower cuspids of the user's mandibular arch when the first arched frame is positioned in the user's mouth. The second arched frame may include a receiving mechanism and may be configured to be positioned proximate to the occlusal surface of a user's maxillary arch such that the second arched frame extends beyond the upper cuspids of the user's maxillary arch when the second arched frame is positioned in the user's mouth. The receiving mechanism may be configured to engage the adjustment mechanism to adjust the position of the mandibular arch relative to the maxillary arch.
