Can adults really expand their maxilla? Is treating sleep apnea with a CPAP or mandibular advancement device only MASKING the problem? How does craniofacial anatomy influence airway health, and what should dentists look for? Dr. Dave Singh joins us to dive into CranioFacial Sleep Medicine. He breaks down how structural issues—like a narrow maxilla, high-arched palate, or limited tongue space—can be root causes of sleep-disordered breathing, rather than just treating symptoms. The episode also touches on controversies in orthodontics and presents evidence supporting interventions once thought impossible in adults. https://youtu.be/WUyeOjKquJU Watch PDP253 on Youtube Protrusive Dental Pearl: Obstructive Sleep Apnea is NOT just a “fat old man disease.” If you’re not screening every patient for sleep and airway issues, you’re missing a huge piece of their overall health. Snoring, bruxism, and craniofacial anatomy are all connected, and understanding these links can transform the way you approach patient care. Key Takeaways: Mandibular advancement appliances are not a universal solution. While effective for some patients, they often fail to address the underlying causes of airway collapse. Craniofacial sleep medicine focuses on airway etiology, not just symptom control, by identifying why the mandible, tongue, and airway behave as they do during sleep. The cranial base plays a foundational role in facial growth, jaw position, and airway size, directly influencing sleep apnea risk. A retruded mandible is frequently due to developmental and epigenetic factors, rather than being an isolated mandibular issue. Sleep apnea has multiple endotypes—including craniofacial, neurologic, metabolic, and myopathic—requiring individualized treatment planning. Bruxism is not a reliable airway-opening mechanism and may be a primitive physiological response to hypoxia rather than a protective behavior. Tooth wear can be an early indicator of sleep-disordered breathing, and should prompt clinicians to screen beyond restorative concerns. Upper Airway Resistance Syndrome (UARS) can occur even when the apnea-hypopnea index (AHI) is low, particularly in non-obese patients with fatigue, pain, and poor sleep quality. Palatal expansion should be understood as a 3D craniofacial intervention, aimed at improving nasal airflow and airway function—not merely widening the dental arch. Effective care depends on an integrated, multidisciplinary approach, involving dentists, orthodontists, sleep physicians, ENTs, and myofunctional therapists.
