Class II malocclusion cases possess a constant challenge to orthodontists since time immemorial. Mandibular retrusion is the most common feature of class II malocclusion, rather than maxillary prognathism. Association of class II with asymmetry, a condition called asymmetric mandibular retrognathia (AMR), gives a tougher challenge to orthodontists for management. The following case presents effective management of AMR using differential loading technique. A young boy aged 12 years presented with mandibular retrognathia associated with facial asymmetry. He was treated with a differential force loading technique using a fixed functional appliance. Results: Improved facial profile with increased mandibular length achieved. A significant reduction in facial asymmetry was also appreciable. Conclusion: Differential force loading technique using fixed functional appliance while being least troublesome for the patient may prove beneficial to harness excellent and satisfactory results with minimal efforts in such cases of mandibular retrusion with facial asymmetries and also decrease the need for surgical correction.
