An intraoral orthopedic appliance with adjustment apparatus and method of manufacture adjustably attaches an appliance upper dental part and lower dental part together. One appliance part is arranged to be attached to a patient's upper dental arch and the other to the patient's lower dental arch. The adjustment changes the anterior-posterior relationship of the two parts. The adjustment is provided by a pair of orthodontic screws on buccal segments of opposite sides of the dental arch which connect the two parts together to provide the adjustment. The orthodontic screws are also attached to the lower appliance part such as to provide a limited movement between the two parts. This allows the patient to move the lower jaw a limited amount with respect to the upper jaw.
