N2 - Because the first molar is one of the first permanent teeth to erupt, it can be lost to decay at an early age.1 In such a case, protracting the second and third molars to close the first-molar extraction space can avoid the need for a future prosthesis.2 Protracting the lower molars is not a simple procedure, however, because a considerable amount of root movement is needed, potentially leading to such problems as soft-tissue folding (gingival clefting), periodontal problems, or root resorption.3-5.
