Dentofacial orthopedic treatment can significantly alter and improve facial appearance in addition to correcting irregularity of the teeth. Functional appliance therapy can be used successfully in Class II malocclusion, e.g., in a growing patient. Twin blocks are simple bite blocks that interlock at a 70° angle and correct the maxillomandibular relationship through functional mandibular displacement. The twin block appliance was developed by Clark in 1980s. They modify the occlusal inclined plane, guiding the mandible forward into correct occlusion. The use of these appliances is greatly dependent on patient's compliance and they simplify the fixed appliance phase. In this case, a 13-year-old adolescent was treated with twin block appliance followed by fixed appliance to detail the occlusion. The design and treatment effects are demonstrated in this case report.
