The MDSA is an intraoral device (mandibular repositioning) for the treatment of snoring and sleep apnea. The device is worn during sleep with the intention to reduce the incidence of snoring and obstructive sleep apnea.
Device Story
MDSA is a custom-made, titratable, two-part intraoral mandibular repositioning device. Constructed from dental impressions and bite registration by a laboratory technician using hard acrylic or double laminate materials. Features an upper tray with a hook component that engages a shelf on the lower tray. An included adjuster key allows for titration by advancing the lower jaw, which moves the mandible and tongue forward to improve airway patency and reduce air turbulence. Used by patients at home or in sleep laboratories. Allows full lateral jaw movement while in situ. Benefits include reduced snoring and improved obstructive sleep apnea symptoms through mechanical airway stabilization.
Clinical Evidence
No clinical data provided; substantial equivalence is based on technological characteristics and design similarities to the predicate device.
Technological Characteristics
Custom-fabricated intraoral device. Materials: Medical Grade 316 Stainless Steel, hard acrylic, or double laminate (hard/soft) functional mouthguard materials. Two-tray system (upper/lower). Mechanical titration via adjuster key and hook-and-shelf engagement. Non-sterile. Designed for single-patient, multi-use.
Indications for Use
Indicated for patients 18 years or older for the treatment of snoring and mild to moderate obstructive sleep apnea. Prescription use only. Not for use in persons younger than 18 years of age.
Regulatory Classification
Identification
Intraoral devices for snoring and intraoral devices for snoring and obstructive sleep apnea are devices that are worn during sleep to reduce the incidence of snoring and to treat obstructive sleep apnea. The devices are designed to increase the patency of the airway and to decrease air turbulence and airway obstruction. The classification includes palatal lifting devices, tongue retaining devices, and mandibular repositioning devices.
Special Controls
*Classification.* Class II (special controls). The special control for these devices is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea; Guidance for Industry and FDA.”

#### D. Description of the Device
The MDSA is an intraoral dental device for the treatment of snoring and sleep apnea. The MDSA is worn during sleep with the intention to reduce the incidence of snoring and obstructive sleep apnea.
The MDSA is a prescription Custom Made titratable mandibular repositioning device for the dental treatment of patients suffering snoring and obstructive sleep apnea.
Patient's dental impressions must be used to construct the device. The MDSA is a 2-part device. With an upper containing the hook component in the front that when in the patient's mouth engages a shelf in the lower.
The MDSA is supplied with an Adjuster Key, which is used to move the hook in the upper to advance the lower jaw forward and accordingly advance the mandible and tongue thereby improving patency of the airway, decrease air turbulence and aid improvement of obstructive sleep apnea.
The MDSA can be molded with commonly available materials used by Dental Laboratories either Hard Acrylic and ball clasps or Double Laminate (Hard /Soft) Functional mouthguard materials for the construction of the device.
A Bite Registration taken at the same time as the impressions facilitates the Laboratory technician correctly locating the components during construction.
Because of its unique design when incitu the patient has full lateral movement and the device can be titrated to the individual patients needs.
The advantage of the MDSA is that its construction can be easily performed by a normally qualified Laboratory Technician using standard Laboratory Equipment. This affords a saving in costs to the end user.

The MDSA components are made from Medical Grade 316 Stainless Steel. The Hook/Screw component is welded into its outer housing to ensure security during use.
### E. Intended Use Statement
The MDSA is an intraoral device (mandibular repositioning) for the treatment of snoring and sleep apnea. The device is worn during sleep with the intention to reduce the incidence of snoring and obstructive sleep apnea.
### F. Technological Characteristics Summary
Similarities between both devices are the following:
- Indications for Use .
- Single Patient .
- . Multi-Use
- . Prescription Device
- . Non-Sterile
- . Custom Fabricated (Fit)
- . Adjustable
- . Environment - Home/Sleep Laboratories
- . Components
- . Two Trays (Upper and Lower)
- . Materials - Stainless Steel, Vinyl, Acrylic
- . Removable
Differences are the MDSA has a separate Adjuster Key versus a winder. The MDSA has a hook in the upper that engages a shelf in the lower tray rather than a lingual bar, which overcomes impedance of the tongue space when the mandible is advanced forward.
The general differences are minor and do not raise safety concerns.
