A combination of abnormal anatomy and physiology of the upper airway can produce its repetitive narrowing during sleep, resulting in obstructive sleep apnea (OSA). Treatment of sleep-breathing disorder ranges from lifestyle modifications, upper airway surgery, continuous positive airway pressure (CPAP) to the use of oral appliances. A proper treatment selection should be preceded by thorough clinical and instrumental examinations. The type and number of specific oral appliances are still growing. The mandibular advancement appliance (MAA) is the most common type of a dental device in use today...

BACKGROUND: Sleep-Disordered Breathing (SDB) varies from habitual snoring to partial or complete obstruction of the upper airway and can be found in up to 10% of children. SDB can significantly affect children's wellbeing, as it can cause growth disorders, educational and behavioral problems, and even life-threatening conditions, such as cardiorespiratory failure. Adenotonsillectomy represents the primary treatment for pediatric SDB where adeno-tonsillar hypertrophy is indicated. For those with craniofacial anomalies, or for whom adenotonsillectomy or other treatment modalities have failed, or surgery is contra-indicated, mandibular advancement splints (MAS) may represent a viable treatment option...

Class II malocclusion is a challenging anomaly in orthodontic practice. Various types of functional appliances are used to correct Class II skeletal and occlusal disharmonies in growing patients, including the Twin-block. We used a modified sagittal-guidance Twin-block appliance combined with a fixed appliance and microimplant anchorage to treat a 13-year-old Chinese boy with a severe skeletal Class II malocclusion and mandibular retrognathia. Normal overjet and a Class I molar relationship were achieved because of the advancement of mandibular development, the restriction of maxillary growth, and dentoalveolar modifications in both the maxilla and the mandible...

Conventional approaches to sleep dentistry concentrate on apneas/ hypopneas that cause periodic desaturations and fragmentations, a strategy that may be leading healthcare professionals to overlook many patients in dental practices with breathing-disturbed sleep. Recent studies have explored a new chronic "stress" paradigm rather than the apnea/hypopnea model to explain damage from sleep-breathing disorders and the progressive nature of this problem. This article will discuss the shortcomings of traditional approaches for dealing with obstructive sleep apnea and other sleep-breathing conditions and provide a protocol, which involved the autonomic nervous system trial, for improving control and management with mandibular advancement appliances...

Early screening and diagnosis help in preventing and intercepting the severity of the malocclusion which helps in addressing the esthetic and functional concerns. Growth modulation such as mandibular advancement has been an effective procedure in orthodontics. Mandibular growth advancer (MGA) and PowerScope are gaining popularity recently as these are effective in achieving the mandibular advancement and ease of fabrication, placement, and wear. MGA was fabricated by making the upper and lower splints separately and are placed in the oral cavity by joining the two splints in the new construction bite using cold cure, MGA when worn during growth phase helps in condylar remodeling in the temporomandibular joint thus helps in advancement of the mandible...
