Oral appliance therapy is as effective as CPAP for reducing blood pressure in patients with hypertension and moderate to severe obstructive sleep apnoea, according to international cardiologists.

They found that patients using a mandibular advancement device (MAD) — which works by protruding the mandible, pulling the tongue forwards and widening the oropharynx — had a 2.5mmHg reduction in mean arterial blood pressure after six months compared with no change with CPAP.
