If you've been diagnosed with mild-to-moderate sleep apnea and can't tolerate CPAP — or simply want a more comfortable alternative — a custom oral appliance from Zapata Dental may change the way you sleep.
Obstructive sleep apnea (OSA) occurs when the soft tissues of the throat — including the tongue, soft palate, and uvula — relax during sleep and partially or completely block the airway. Breathing stops, oxygen drops, and the brain rouses you just enough to resume breathing. This cycle repeats dozens or even hundreds of times per night.
Most patients with OSA have no idea this is happening. Their partner hears the snoring, the gasping, and the restless sleep — but the patient wakes exhausted without knowing why. Over time, untreated OSA significantly raises the risk of hypertension, heart disease, stroke, and type 2 diabetes.
Soft tissue collapses and blocks the upper airway during sleep
Loud snoring, gasping, or choking sounds — noticed by a partner
Repeated drops in blood oxygen saturation stress the heart and brain
Waking unrefreshed, morning headaches, daytime sleepiness, difficulty concentrating
Untreated OSA significantly increases risk of high blood pressure, heart disease, and stroke
Many patients are unaware of their sleep apnea until a partner raises concerns. Talk to your doctor if you recognize these signs.
Not everyone who snores has apnea, but loud or persistent snoring is the most common symptom reported by partners.
Witnessed episodes of breathing cessation followed by gasping or choking sounds during sleep are a strong indicator of OSA.
Despite a full night in bed, you feel exhausted — because sleep fragmentation prevents you from reaching restorative deep and REM sleep.
Falling asleep during meetings, while driving, or during other activities is a serious red flag that warrants prompt evaluation.
Headaches upon waking — caused by elevated carbon dioxide levels from repeated breathing interruptions during sleep.
Sleep deprivation from OSA impairs cognitive function, memory consolidation, and mood — often mistaken for other conditions.
A mandibular advancement device (MAD) is a custom-fabricated oral appliance that fits like a sports mouthguard — but for both upper and lower arches simultaneously. It repositions your lower jaw a few millimeters forward during sleep.
This small forward shift has a significant effect on the upper airway: it tightens the soft palate, moves the tongue base forward, and increases the cross-sectional area of the airway — preventing the collapse that causes apnea events. No electricity, no mask, no hose.
The degree of advancement is adjustable. Dr. Zapata titrates (fine-tunes) the position over multiple follow-up appointments until your airway is open and your symptoms are resolved, as confirmed by a follow-up sleep test.
Lower jaw drops back during sleep, tongue base follows, soft tissue collapses over airway — causing obstruction and apnea events
Mandibular advancement device holds the lower jaw 3–8mm forward, pulling the tongue base away from the back of the throat and opening the airway
Unobstructed airflow, no apnea events, no oxygen drops — restful, restorative sleep throughout the night
Important: A physician diagnosis (sleep study) is required before receiving an oral appliance. This ensures your apnea severity is properly classified and the right treatment level is selected.
Both are proven treatments. The best choice depends on your apnea severity, your lifestyle, and your compliance history.
A physician orders a polysomnography (in-lab sleep study) or home sleep test to diagnose OSA and determine its severity (Apnea-Hypopnea Index / AHI). This step must occur before any dental appliance is prescribed. If you haven't had a sleep study, we can refer you to a sleep medicine specialist.
Your physician refers you for oral appliance therapy. Dr. Zapata performs a dental examination to confirm you have adequate dental health to support an appliance (no active gum disease, sufficient teeth).
We take precise digital scans of your upper and lower arches. A bite registration records your jaw position. These are sent to the dental lab where your custom appliance is fabricated.
Your custom appliance arrives and Dr. Zapata checks the fit at a delivery appointment. You leave with the appliance and detailed instructions on insertion, removal, and care. The initial position is conservative — gradual advancement follows.
Over several follow-up visits, Dr. Zapata advances the appliance incrementally until your symptoms resolve and you are sleeping well. Some appliances are patient-adjustable for fine-tuning at home.
A follow-up sleep study confirms the appliance is effectively controlling your apnea at the final titrated position. Results are reported back to your physician to complete the treatment loop.
Unlike most dental treatment, sleep apnea appliances are a medical procedure — which means they may be covered under your medical insurance plan, not your dental plan.
Contact our office and we will verify your medical insurance benefits before treatment begins. We handle the paperwork so you can focus on getting better sleep.
