A method of forming oral orthotic systems (100) to position and/or stabilize a mandible of a patient includes providing an upper dental member (20) adapted to be placed in connection with upper dentition of the patient, providing a lower dental member (30) adapted to be placed in connection with lower dentition of the patient and providing a plurality of posterior mounting structures (40). Each of the posterior mounting structure is adapted to be attached to one of the upper dental member or the lower dental member at a posterior, buccal position thereon. Each of the posterior mounting structures includes an extending member (42) which includes a plurality of positions (44) at which one of a plurality of connectors (50) is attachable to the extending member. Force may be applied to the mandible of the patient via at least one of a plurality of different mechanisms via attachment of a component of the mechanism (120) to at least one of the posterior mounting structures. The upper dental member and the lower dental member are formed, independently, from at least one polymeric material.
