There are two main types of sleep disorders under SDB

  • Obstructive sleep apnea (OSA)

  • The Most common form of SDB is Obstructive Sleep Apnea. OSA occurs when there are repeated episodes of complete or partial blockage of the upper airway during sleep
  • Apnea is a cessation of airflow for ≥10 seconds, a reduction of airflow greater than 90% of baseline
  • Hypopnea: a decrease in airflow lasting ≥10 seconds with a 30% oxygen reduction in airflow and with at least a 4% oxygen desaturation from baseline

Obstructive Sleep Apnea can be Mild, Moderate, or Severe.

  • AHI (Apnea–Hypopnea Index) is the numerical value assigned for how many times a person pauses their breathing per given time.

Oral Appliances for Sleep Apnea | Snoring Mouth Guards Silver Spring & Beltsville

Treatment of OSA with oral appliance & How Does It Work?

Oral appliances are indicated for the treatment of snoring and mild to moderate sleep apnea. Oral appliances also offer alternative for patients with severe OSA who cannot or will not tolerate positive airway pressure therapy or CPAP. Oral appliances for OSA must be prescribed by a physician and fitted by a dentist. The mechanical holding of the mandible forward in relation to the maxilla, and the prevention of the tongue from collapsing into the airway during sleep provides mechanisms that decrease the collapsibility and an increase in the dimensions of the upper airway. This simple and viable option in the treatment of sleep-related breathing disorders reduces the potential for obstruction.

Oral Appliances Types

The two main types of appliances for SBD are those that advance the mandible in relation to the maxilla, and those that hold the tongue in the protruded position. The custom made nocturnal mandibular advancement device is the most commonly used device, and is farther divided into adjustable and non adjustable. The adjustable device allows for adjustments for titration. Oral appliances are easy and comfortable to wear and most people adjust to the appliance with in couple of weeks.The small and convenient size makes it easy to carry it when traveling. Makes for a non-invasive reversible treatment.
The tongue retaining device is least popular because it lacks the ability to adjust for titration, can dislodge because of lack of suction and therefore has low compliance because of comfort issues. Mandibular advancement appliances are the most commonly used.

Patient Review by Dora Elaine T

I was deciding between a hard or soft nightguard for my teeth. Dr. Tekle took her time to explain all of the questions I needed to ask to make an informed decision. She also gave me some websites where I could get information. And, maybe most importantly, she showed me a hard nightguard so that I could touch it and know exactly what it would be like. I already wear a soft nightguard and know what it is like. Really seeing and touching was very helpful.

Patient Review by David P

I have sleep apnea, and I really like my CPAP machine. But it's a pain in the patootie when I travel. It's bulky and at my age dragging it and luggage around is more trouble than I need. So I asked my ENT about an oral appliance and he recommended Dr. Tekle. Getting fitted took a couple three hours over two visits measuring breathing and trying various means of keeping my air way open. Dr. Tekle was very careful to make sure she got it right. Then after another sleep test has come more adjustments. I'll have three more visits to make sure everything is right.

Patient Review by Carlton D

I was referred to Dr. Tekle by a co-woker, this was one of the best thing that happened to me. I was suffering from sleep apnea and refused to use the cpap machine. I was averaging about 3-4 hours of sleep a night. I was falling asleep in meetings, at my desk, and watching television on the couch was a joke. My co-workers would joke on how long it would take me to fall asleep. I made an appointment with Dr. Tekle and my life has totally changed and everyone around me has noticed. Dr. Tekle fitted me for an Oral Sleep Appliance. OMG...I can't really put into words the difference this appliance has improved my sleeping, I sleep on average about 6-8 hours a night now. I'm no longer falling asleep in meetings, at my desk, and I can actually watch an entire show without falling asleep. If you have sleep apnea issues I HIGHLY recommend Dr. Tekle and her staff and the Oral Sleep Appliance.

Patient Review by Robert R

I was referred for an oral appliance for my sleep apnea. I did not know what to expect and Dr. Tekle walked me through the process and tested and re-tested my jaw position to make sure it would work for me - it did. Additionally, the staff worked with my referring Dr. and insurance to get approval in a timely manner. Now, I am sleeping better with more energy! Great, friendly practice.

Patient Review by John B

Not only have I received regular dental care from Dr. Tekle, which has been excellent by the way, but recently utilized Dr. Tekle's services for Sleep Apena. The service provided has allowed me to no longer require a CPAP machine thereby providing a less intrusive sleep experience and saves from the cost of maintenance and up keep of the CPAP device.

Fitting for new device was simple. Device itself worked miraculously. Snoring reduced 100% per sleep monitor SnoreLab (which is great and free trial and usage; costs only 2.99 to save multiple nights recordings).
