Background: Patients with anterior open bite appear both dentoalveolar component and with increased skeletal vertical dimension. Objectives: The main objective was to treat open bite with an ideal overbite and overjet relationships and to maintain proper intercuspstion with midline correction.Results: The goal of the treatment has been achieved according to patients' desire and satisfactory interdigitation. In further follow up no relapse has been seen. Conclusion:The treatment resulted in an aesthetic, functional, and stable occlusion, along with an improved facial profile.

Obstructive sleep apnea (OSA) is a recurrent respiratory condition related to sleep, characterised by sporadic narrowing and pharyngeal airway obstruction, with adverse effects on sleep efficiency and gaseous exchange. OSA is a poorly identified medical disorder where the diagnosis of undiagnosed patients involves a thorough history and concentrated physical assessment. The combination of anatomical and neuromuscular risk factors in the pathogenesis of OSA has resulted in a varied approach to its management. Individuals with OSA often feel unrested, fatigued, and sleepy during the daytime. These declines in daytime function can translate into higher rates of job-related and motor vehicle accidents. Screening to identify unrecognized OSA followed by appropriate treatment might improve sleep quality and normalize the AHI and oxygen saturation levels to prevent adverse health outcomes. The role of orthodontist in screening and cure is treasured in the multidisciplinary administration of OSA. The aim of this assessment is to summarize the recent information’s on the unique contributors to OSA with a centre of attention on diagnostic strategies and various orthodontic appliances which may also be considered for the cure of OSA and designed to offer guidance to practising orthodontists on the suggested role of the speciality of orthodontics in the management of obstructive sleep apnea.
