Abstract :
Class II malocclusion cases are of interest to orthodontists since they constitute a significant chunk of cases they treat. Still, they're one of the most grueling malocclusions to diagnose and treat.There lies a significant difference in the frequency of Class II malocclusion among various populations. The frequency of Class II malocclusion in India varies from 1.9% in Rajasthan to 8.37% in South India. Class II division 2 (Deckbiss) malocclusion is characterized by mandibular incisors positioned posterior to the cingulum of retroclined maxillary incisors. It usually presents with reduced overjet and increased overbite.The treatment approach of Class II division 2 malocclusion is different for different age groups. In growing cases, growth modulation with myofunctional appliances is recommended but in adult cases, orthodontic camouflage or orthognathic surgery is the recommended treatment modality. When orthodontic treatment alone is ineffective or when facial aesthetics is grossly undermined, orthognathic surgery is the choice of treatmentIn the present case series, two adult cases of severe Class II division 2 (Deckbiss) malocclusion were treated orthosurgically with BSSO. This case series demonstrates that treatment of Class II division 2 (Deckbiss) malocclusion in adult patients is a challenging task and a combined orthodontic-surgical approach can be used to obtain optimum aesthetics & functional efficiency.
