Oral appliance therapy is a proven alternative to CPAP for individuals diagnosed with obstructive sleep apnea (OSA). Patients who cannot tolerate CPAP or are looking for a more convenient solution often consider a custom oral appliance for sleep apnea. These appliances are not over-the-counter devices—they are custom-made to fit the patient’s unique dental and jaw structure.
Understanding the oral appliance fitting process helps patients know what to expect and make informed decisions about their treatment. This guide explains each step in the process, from initial evaluation to final fitting and follow-up.
Step 1 – Initial Evaluation and Treatment Candidacy
The first step in receiving a custom oral appliance is a clinical evaluation by a trained sleep dentist. This appointment includes a review of your medical and dental history, a sleep apnea screening, and a physical examination of your mouth and jaw.
If the patient has not yet received a diagnosis of sleep apnea, a sleep study may be recommended. Most commonly, a home sleep apnea test is used to confirm the presence and severity of obstructive sleep apnea. Once diagnosed, the dentist determines if the patient is a good candidate for oral appliance therapy.
Key Criteria for Oral Appliance Eligibility
- Diagnosis of mild to moderate obstructive sleep apnea
- Inability to tolerate or preference against CPAP therapy
- Adequate dental health and jaw structure for appliance support
- No significant issues with temporomandibular joint (TMJ) function
During this evaluation, the dentist explains how the oral appliance works, what results can be expected, and how it will be customized for the patient’s mouth. Patients can ask questions about the fitting timeline, comfort, and ongoing care.
This first step is essential to ensure the appliance is both safe and effective for long-term use in managing sleep apnea symptoms.
Step 2 – Impressions and Digital Scanning
Once a patient is approved for oral appliance therapy, the next step involves capturing precise measurements of the mouth. This is done to ensure that the custom oral appliance for sleep apnea fits securely and aligns properly with the jaw and teeth.
Methods Used for Dental Impressions
There are two main techniques used to capture the patient’s oral anatomy:
- Digital Intraoral Scanning: A handheld scanner creates a 3D image of the teeth, bite, and gums. This method is highly accurate and more comfortable for the patient.
- Traditional Dental Impressions: A moldable material is placed in a tray and pressed against the upper and lower teeth to create a precise impression. While effective, this method is less commonly used when digital scanning is available.
Recording Bite Registration and Jaw Position
In addition to the impressions, the provider records how the upper and lower teeth come together (bite registration) and measures the ideal position for the lower jaw. These measurements are critical for setting the appliance to gently advance the jaw, which helps maintain an open airway during sleep.
Importance of Accurate Scans
Accurate impressions and scans enable the dental lab to fabricate an appliance tailored to the individual’s oral structure. A properly fitted appliance minimizes jaw strain, improves comfort, and increases patient compliance with nightly use.
This step typically takes less than an hour and is a non-invasive procedure. The data collected is then sent to a dental laboratory for the fabrication of the appliance.
Step 3 – Custom Appliance Fabrication
After the digital scans and bite records are complete, the data is sent to a dental laboratory that specializes in the fabrication of sleep apnea appliances. The lab utilizes this information to create a custom oral appliance for sleep apnea that is tailored to the patient’s unique anatomy.
Materials and Design
The appliance is made from biocompatible, medical-grade materials designed for durability, safety, and long-term wear. These materials are strong enough to hold the jaw in a forward position during sleep while remaining comfortable inside the mouth.
Each appliance is designed to:
- Maintain an open airway by advancing the lower jaw
- Align with the patient’s bite without causing tooth movement.
- Prevent pressure on soft tissues and joints.
- Be adjustable, if required, for further jaw advancement.
There are various types of oral appliances, and the dentist selects the appropriate design based on the patient’s anatomy, the severity of sleep apnea, and their personal comfort needs.
Turnaround Time
The production process typically takes 2 to 3 weeks. During this time, the lab fabricates the appliance according to the dentist’s specifications and the patient’s scanned models. Once complete, the appliance is shipped back to the dentist’s office for final fitting.
This step is essential to ensure that the final product delivers both comfort and effectiveness in managing obstructive sleep apnea.
Step 4 – Appliance Fitting and Adjustment
Once the custom oral appliance is returned from the lab, the patient returns to the dentist’s office for the fitting appointment. This step ensures that the oral appliance for sleep apnea fits securely, functions properly, and feels comfortable during use.
What Happens During the Fitting
The dentist places the appliance in the patient’s mouth and checks the following:
- Alignment with the upper and lower teeth
- Jaw position and bite registration
- Comfort around gums and soft tissues
- Retention and ease of insertion/removal
The goal is to ensure that the appliance fits snugly without causing irritation, tooth movement, or jaw discomfort. If any areas feel tight or cause pressure, the dentist can make minor adjustments on-site.
Initial Jaw Advancement Settings
Most oral appliances are adjustable. During the fitting, the dentist sets an initial level of jaw advancement tailored to the patient’s specific needs. This position helps open the airway without straining the jaw or causing TMJ discomfort.
Patients are instructed on:
- How to insert and remove the device properly
- Cleaning and storage procedures
- How to track comfort and sleep quality at home
Importance of a Proper Fit
A properly fitted appliance is essential for effective treatment. Poor fit may lead to reduced efficacy, discomfort, or poor compliance. This fitting appointment allows the dentist to ensure the device is ready for daily use and helps the patient feel confident in using it correctly.
The patient is typically asked to wear the appliance nightly for a few weeks before returning for follow-up adjustments.
Step 5 – Follow-Up and Long-Term Monitoring of Your Sleep Apnea Device
After the patient begins using the custom oral appliance for sleep apnea, regular follow-up is essential to confirm the therapy’s effectiveness and to make any necessary adjustments. This phase ensures long-term comfort and consistent results.
Follow-Up Oral Appliance Appointments
The first follow-up typically occurs within a few weeks of the fitting. During this visit, the dentist evaluates:
- Appliance comfort and fit
- Changes in sleep quality or symptoms
- Any side effects, such as jaw soreness or bite changes
If necessary, the jaw advancement setting may be adjusted to optimize airflow during sleep. Additional follow-ups may be scheduled over the next few months to fine-tune the appliance.
Ongoing Monitoring of Sleep Apnea
To confirm the effectiveness of the treatment, patients may be asked to complete a follow-up sleep study, often using a home sleep testing device. The results help determine if the appliance is reducing apneic episodes and improving oxygen levels.
Patients are encouraged to report any new symptoms or discomfort they experience. Some individuals may require minor refitting over time due to dental changes, weight fluctuations, or other factors.
Long-Term Appliance Maintenance
Patients should schedule routine dental check-ups to monitor oral health, jaw alignment, and appliance wear. With proper care, most custom oral appliances can last several years, although replacement may eventually be necessary.
Good maintenance practices include:
- Cleaning the appliance daily with non-abrasive cleanser
- Storing it in a protective case
- Avoiding exposure to heat or pressure
Long-term follow-up helps ensure that oral appliance therapy remains a reliable and comfortable alternative to CPAP.
