What is a mandibular advancement device?

For dentists managing mild-to-moderate obstructive sleep apnea cases, a MAD offers a proven CPAP alternative backed by the American Academy of Sleep Medicine. The appliance works by translating the mandible 50-75% of maximum protrusion, which tightens the pharyngeal musculature and keeps the tongue from collapsing against the posterior airway wall. Most patients reach therapeutic titration within 4-8 weeks of initial delivery, with compliance rates consistently higher than CPAP in head-to-head clinical studies because the device is small, silent, and portable.

From a lab standpoint, accurate fabrication depends on a precise protrusive bite registration taken at 50-70% of maximum advancement and a full upper and lower arch impression or intraoral scan. Digital workflows reduce stone model error and allow the technician to verify occlusal contact points before delivery. At Dani Dental, MAD cases processed from digital scan file typically leave the bench within 5 business days, which keeps the chair-time commitment predictable for the prescribing dentist.

For general dentists adding sleep services and for prosthodontists managing complex occlusal cases, understanding the lab side of MAD fabrication matters. Poorly calibrated bite registrations, incorrect vertical opening, or ill-fitting frameworks cause nighttime discomfort and rapid patient drop-off. A lab with a documented appliance workflow, not a generic pressable blank, is the variable that separates a sleep program that retains patients from one that generates remakes.
