Abstract
A system of orthodontic appliances and method for their use for gaining space in a dental arch without extraction. Space is gained in the maxillary arch primarily through a transpalatal bar, transmitting force to selected teeth through a maxillary lingual sheath, the receiving portion of the sheath having a mesial offset of about eight degrees. Additional space in the maxillary arch may be gained by employing an extraoral force appliance, transmitting force through a maxillary buccal tube carried on a selected pair of maxillary molars. The mandibular arch is treated by applying similar forces to selected molars through a lip bumper. This appliance transmits force through a mandibular buccal tube that receives the bumper in a passage having a mesial offset of about five degrees. The mandibular buccal tube also carries an archwire receiving passage, distally offset by about four degrees.
