Treatment and follow-up
A treatment worn in your mouth during sleep, tailored to your situation and monitored over time.
A mandibular advancement device (MAD) holds the lower jaw slightly forward to help air pass through. It may be offered for some cases of obstructive sleep apnoea, depending on the assessment.
Dr Christophe Chevalier mainly prescribes the ResMed Narval CC oral appliance. The choice of device and the practitioner who fits it is discussed with you, according to your situation.
Usually prescribed appliance
A custom-made oral appliance produced from dental impressions. Its two splints are joined by connecting rods; the practitioner fitting the device gradually adjusts the degree of advancement.
It is worn during sleep and works without a machine or mask.

Other oral appliances may be discussed if the characteristics of your mouth, comfort or treatment requirements justify this.
Continuous positive airway pressure (CPAP) remains another option. The choice depends in particular on the severity of the disorder, associated medical conditions and whether dental treatment is feasible.
Visit the My CPAP pageA protective mouthguard for tooth grinding is not a mandibular advancement device for apnoea. Before buying an anti-snoring device, discuss whether you need a sleep assessment.
Prescribing a device involves two complementary assessments: your sleep assessment and an examination of your teeth and jaw. An oral appliance is not suitable in every situation.
Significant gum disease, very loose teeth, insufficient retention or certain painful conditions and diseases of the jaw joints may limit the use of an appliance or make it unsuitable.
In other cases, preliminary dental treatment or an additional opinion may allow the suitability of an appliance to be reassessed.
This page concerns the Narval appliance intended for adults. Treatment options for children or adolescents require a specific assessment; they cannot be inferred from the adult care pathway.
A contraindication to an oral appliance does not mean there is no treatment: we discuss a suitable option together. This list does not replace an examination or the contraindications in the device's instructions for use.
Follow the wearing instructions given when the appliance is fitted. Report persistent pain, joint discomfort, a change in how your teeth meet, a poor fit or breakage to the practitioner who adjusts your appliance. If your sleep symptoms persist or return, also contact the clinic.
After use, clean it with lukewarm drinking water and a dedicated brush, rinse it, dry it and put it away in its case. ResMed also recommends thorough cleaning twice a week with a compatible product.
Avoid hot water, toothpaste, mouthwash, soap and household cleaning products. Follow your appliance's instructions for use and the manufacturer's instructions.
