Molar expansion is a secondary reaction to palatal root torquing forces placed in the anterior part of a rectangular archwire. The normal methods to counteract this expansion are discussed, and an additional method using a buccal arch placed in the molar extra-oral traction tubes is described. The method is illustrated with a case history, and some of the advantages of the technique are discussed.
