A Design of Oral Appliance for Obstructive Sleep Apnea (Preprint)

BACKGROUND As per the current epidemiological studies, the prevalence of obstructive sleep apnea (OSA) among the adult population is very high. Oral appliances (OA) has emerged as the most recommended alternative treatment option for mild to moderate OSA. OBJECTIVE The objective of this article is to develop a new design of OA named “customized maxillary oral appliance”, for managing moderate obstructive sleep apnea (OSA) syndrome. METHODS The design proposed in this clinical technique is first of its kind that is fabricated on the maxillary arch. Customized maxillary oral appliance is developed by combining the principles of the three most popular OA’s used in OSA, namely soft palate lifters, tongue retaining devices, and mandibular advancement devices. RESULTS A new design of OA for the maxillary arch is proposed for managing moderate OSA. CONCLUSIONS Given the potential impact of OSA on general and mental health and the side effects of existing appliances there is a need for a new remedy to be introduced in the field of sleep medicine. This novel design can provide a new therapeutic op¬tion for patients with moderate OSA.

Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder with periodic reduction or cessation of airflow during sleep. It is associated with loud snoring, disrupted sleep, and witnessed apneas. Treatment of OSA varies from simple measures such as oral appliances and nasal continuous positive airway pressure (CPAP) to surgical procedures like uvulopalatopharyngoplasty and tracheostomy. Oral appliances are a viable nonsurgical treatment alternative in patients with OSA, of which mandibular advancement devices are most common. Edentulism which contributes to the worsening of OSA reduces the number of available therapeutic strategies and is considered a contraindication to oral appliance therapy. This clinical report describes the treatment of a 63-year-old edentulous OSA patient for whom a mandibular advancement device was designed.

Mandibular Advancement Devices

Oral appliance therapy is increasingly prescribed as a non-invasive treatment option for patients diagnosed with obstructive sleep apnea. The custom-made titratable mandibular advancement devices (MAD) are the recommended type of oral appliances. Mandibular advancement devices are efficacious in reducing the severity of obstructive sleep apnea, however, only to a lesser extent than standard therapy using continuous positive airway pressure (CPAP). Although oral appliance therapy is known to reduce the severity of obstructive sleep apnea in most of the patients, one out of three patients still show negligible improvement under MAD therapy. Therefore, the selection of the appropriate candidates for this therapy is imperative and several upfront prediction tools are described. Overall, the health outcome of mandibular advancement device therapy is similar to that of CPAP, probably due to the inferior compliance of CPAP compared to MAD therapy, resulting in similar clinical effectiveness.

Mandibular Advancement Devices

There are more than 20 different types of current commercially available mandibular advancement devices (MAD). Although there are so many different types of MAD available in the market, these designs are often not flexible enough to be adjusted to fit these devices to all possible cases. The aim of this study was to design and develop a new type of mandibular advancement device which used friction effect to achieve mandibular forward, and ensure it would not slide back during sleeping. The new type of mandibular advancement device could be quickly adjusted, and had 3-degree of freedom. ANSYS software was used to simulate whether the new design was strong enough. From the simulation it was found that the new innovative design was reliable and easy to be used for obstructive sleep apnea patients.
