Background: Evidence suggests that sleep bruxism is centrally regulated, and that the highest risk factor associated with sleep bruxism is obstructive sleep apnea. Current treatments for sleep bruxism include dental night- guards or occlusal splints, which are often provided without upper airway or sleep assessments. Methods: In this case report, we used biomimetic oral appliance therapy to address sleep bruxism by redeveloping the maxilla and repositioning the mandible in a 17 yr. old, female patient. Results: The upper airway volume increased by 313% (from 7.7 cm 3 to 24.1 cm 3 ) and the minimum upper airway cross-sectional area increased by 230% from (120 mm 2 to 276.5 mm 2 ), which improved both sleep bruxism and orthodontic relapse. Conclusion: We conclude that dentists and orthodontists can help in the recognition and treatment of both sleep bruxism and malocclusion, thereby preventing systemic co-morbidities associated with obstructive sleep apnea.
