Sleep Apnea Patient Instructions

Device Description 

Dandy Anti-Snoring & Sleep Apnea Devices are intraoral devices used for treating snoring and sleep apnea,  and consist of two custom fitted trays which fit over the upper and lower teeth and engage by means of adjustable lugs, or by the Herbst mechanism which is a rod and tube assembly that orientates the jaws in a predetermined relationship. These devices function as a mandibular re-positioner, which acts to increase the patient’s pharyngeal space, improving their ability to exchange air during sleep. The devices are custom  made for each patient and have the ability of the adjustment mechanism, which enables the amount of man dibular advancement, to be set by the patient’s dentist or physician at the time of fitting the device.  The devices are sold by prescription only. 

The functional relationship built into the devices acts to position the lower jaw forward and open vertically from its normal location which causes a protrusion of the mandible in relation to the maxilla. This forward repositioning, which is temporary while the appliance is being used, increases the pharyngeal space which assists the patient with improved air exchange. The prescribing dentist or physician determines the exact repositioning of the lower bite via a manual process or bite gauge. The dentist or physician is also able to fine tune the jaw positioning clinically as needed by altering the Herbst mechanism and/or adjusting the acrylic portions of the appliance. 

Appliance Selection, Sleep Study, Device Exam & Prescribing 

The selection of the appropriate snoring/sleep apnea appliance will depend on patient and/or doctor  preference. While the appliances may look different the basic function of the appliance remains the same and therefore, most appliances will achieve very similar results. 

It is imperative that each patient have a sleep study completed prior to prescribing an intraoral appliance for use. The sleep study will determine the level or severity that the patient is currently experiencing and this information should be used by the prescribing dentist to determine the needed device. 

Each patient should be subject to a complete and comprehensive dental exam prior to prescribing a snoring  or sleep apnea device. Once the patient has undergone a comprehensive dental exam complete with full  records and a sleep study than the dentist can accurately prescribe a snoring or sleep apnea device. 

Indications for Use
