A MAD resembles a sports mouthguard or orthodontic retainer, but with separate upper and lower trays connected by a mechanism that holds the lower jaw forward. Modern devices are slim, comfortable, and made from medical-grade materials. They cover the teeth but do not cover the palate in most designs, minimizing gag sensation.

Custom MADs are fabricated from digital impressions for precise fit, use FDA-cleared titratable mechanisms for controlled advancement, and are prescribed and monitored by a trained dental sleep medicine clinician. Over-the-counter devices are one-size-fits-most, non-titratable, uncomfortable, and lack clinical oversight. The efficacy and safety profiles are not comparable.

With proper care, most custom MADs last three to five years. Devices worn by patients who brux heavily during sleep may need earlier replacement due to wear. Annual examination assesses device integrity, retention, and material condition. Most medical insurance plans cover replacement devices at regular intervals.

Most patients adapt within one to two weeks. Initial sensations include jaw stiffness upon morning awakening, slight excess salivation, and awareness of the device. These acclimation effects diminish rapidly. The device should not cause pain — if it does, the fit or advancement position needs adjustment. Long-term comfort ratings from patients using custom MADs are consistently high.

Yes. Modern titratable MADs allow limited mouth opening while maintaining the mandibular advancement position. This is important for comfortable breathing during sleep (some patients partially mouth-breathe) and for reflexive swallowing. Devices that lock the jaw closed are outdated and poorly tolerated.

Mild jaw stiffness for 15 to 30 minutes after removing the device in the morning is common during the first few weeks and typically resolves as the muscles adapt. Prescribed morning exercises (biting on a Morning Repositioner or performing jaw stretches) restore the bite to its normal position. Persistent jaw pain indicates overadvancement and requires protrusion reduction.

Brush the device with a soft toothbrush and non-abrasive soap or denture cleaner each morning after removal. Rinse thoroughly. Soak weekly in denture cleaning solution or a specialized oral appliance cleaner. Store in the provided ventilated case when not in use. Avoid hot water, which can warp the thermoplastic material.

Yes, in most cases. The MAD distributes retention forces across multiple teeth, minimizing stress on any individual tooth. Teeth with crowns or implants provide adequate retention as long as they are structurally sound. The clinician evaluates your specific dental status during the consultation and selects a device design compatible with your restorations.

New crowns, fillings, or other dental changes may alter the fit of the MAD. After any dental work that changes tooth shape or size, bring the device for a fit check. Minor adjustments can often be made in-office. If the change is significant, a reline or new device may be needed. Communication between the sleep dentist and restorative dentist prevents fit disruptions.

Yes. OSA occurs every night, so treatment must be nightly. Unlike CPAP (which some patients use only during "bad nights"), oral appliance therapy is most effective with consistent nightly use. The device becomes part of the bedtime routine — most patients report that sleeping without it feels noticeably worse within a few nights.

Treatment controls sleep apnea — it does not cure the underlying anatomical predisposition. When the device is removed, the airway returns to its untreated dimensions and apnea events resume. This is why nightly use is essential. In some patients, significant weight loss or surgical airway modification may reduce the severity enough to discontinue appliance therapy, but this is the exception rather than the rule.

Custom MADs range from $1,500 to $3,000 at ADSC depending on the device model selected. Medical insurance typically covers oral appliances for diagnosed OSA, often at 50 to 80 percent after deductible. The office handles medical insurance pre-authorization and provides cost estimates based on verified benefits before fabrication.

Titration is the process of gradually advancing the mandibular position (in 0.25 to 0.5 mm increments) to find the best protrusion that maximizes airway improvement while maintaining TMJ comfort. Starting at the target position immediately would cause excessive jaw soreness. Gradual advancement over four to eight weeks allows the muscles and joints to adapt. The final position is verified by follow-up sleep testing.

Most patients experience significant or complete snoring reduction. Mandibular advancement tensions the pharyngeal soft tissues, reducing the vibration that produces snoring. Residual snoring after best titration may indicate nasal obstruction contributing to mouth breathing, which may require additional evaluation.

ADSC uses FDA-cleared, titratable devices including the SomnoDent, EMA (Elastic Mandibular Advancement), Herbst-style devices, and Narval CC. The device selection is based on the patient's dental anatomy, jaw mobility, and preference for specific materials and mechanisms. No single device is best for every patient — individual selection produces the best outcomes.
