Arrested Growth: Myth or Reality

In Class II, Division I malocclusion is a common problem often associated with mal-relationship of dental bases and mal-alignment of dentition. The approaches to treat Class II, Division I malocclusion include growth modulation, dental camouflage and surgical orthodontics. A 16-year-old female patient with Class II, Division I malocclusion associated with excessive over jet, deep bite, and retrognathic mandible reported to the Department of Orthodontics and Dentofacial Orthopedics, Kothiwal Dental College and Research Center and Hospital, Moradabad. The case was treated with twin block appliance by taking into consideration the over jet which was to the tune of 13 mm and the mandible which was fully locked within the maxilla. The patient was post-pubertal by 3 years and by seeing lateral cephalogram, it falls in CVMI5 stage which mean normally that the growth is only 10% left and theoretically, not appropriate for functional appliance therapy. The patient was treated with twin block appliance to catch up with the arrested growth of mandible followed by fixed mechanotherapy. The result was tremendous and up to the mark.
