Correction of Class II Malocclusion Using a Resin Block Build up with Class II Elastic in an Adult Patient: A Case Report

Main Article Content
Abstract
Class II malocclusion is one of the most prevalent orthodontic problems that is commonly associated with mandibular retrognathia. Treatment in adults poses a challenge because growth modification is no longer possible, and most corrections rely on camouflage mechanics or orthognathic surgery. This report presents a 23-year-old female with a skeletal Class II normodivergent pattern, retrognathic mandible, and proclined maxillary incisors. A modified fixed twin block appliance was combined with fixed orthodontics as a non-extraction camouflage strategy. After 18 months, the patient achieved improved facial balance, normalized overjet and overbite, and Class I molar relationships. Skeletal change was minimal, while the effects were largely dentoalveolar; however, vertical control and occlusal stability were favorable. This case highlights the limited but valuable role of fixed twin block appliances in adults as a cost-effective camouflage option where surgery or extraction is not preferred.
