The case for this paper was an female patient with the midline discrepancy due to asymmetric malpositions of mandibular molars in the anteroposterior plane of space. After considering the treatment priority and solutions for each problem with risks and benefits on the basis of problem list, it was decided that two first premolars in the maxillary arch and the right second premolar and the left first premolar in the mandibular arch would best be extracted in order to achieve the treatment goals. It took thirty five months to finish the case and most of the time was spent for improving a Class II relation to a Class I as a part of the active treatment using a combination of power chain and bilateral Class II or asymmetric elastics. Clinical examination and evaluation of the patient's records for the post treatment and the 2 years following completion of active treatment revealed continued good occlusion and function.
