No. Modern CBCT technology used at our North Austin office uses significantly less radiation than traditional medical CT scans. This process is a short, 20-second scan that provides important insight into safely treating your sleep apnea.
A 3D airway scan (CBCT) is a diagnostic method used to measure oropharyngeal airway volume and alveolar bone height. CBCT 3D airway evaluations have been shown to provide significant diagnostic value for evaluating patients for obstructive sleep apnea [1] (Benítez-Cárdenas et al., 2025). At Enamel Dentistry The Domain, this process is used to ensure that you are able to safely undergo oral sleep apnea treatment. Our 2026 standard of care verifies that your teeth have at least 50% bone support to safely withstand the mechanical forces of a mandibular advancement device.
Nobody wants to trade a snoring problem for a tooth loss problem. It is a common fear: “Will this device pull my teeth out?” For many Austin professionals working high-stress jobs in the North Austin tech corridor, a custom sleep device can be life-changing. Careful attention must be given to device placement to confirm that a patient’s oral foundation can handle a device’s torquing pressures. At Enamel Dentistry The Domain, we replace this guesswork with structural engineering. Before we build your $2,800 device, we use 3D CBCT technology to ensure your jawbone is strong enough to support your journey to better sleep.
CBCT scans have been shown to be a highly accurate and non-invasive method for measuring alveolar dimensions [3] (Xia et al., 2015). Unlike 2D bitewing X-rays that you undergo at a standard cleaning, the CBCT (Code D0330) allows us to see the Airway-to-Bone Ratio. We are not just looking for cavities. We are measuring two critical metrics:
A Mandibular Advancement Device (MAD) works by gently pulling your lower jaw forward. Tooth movement depends on forces on the periodontal ligament by MAD; dentition resistance greatly influences changes in tooth position [4] (Linsen et al., 2025). This creates tension in your teeth and jaw. If you have a history of gum disease or thin bone, this tension can act as accidental braces, moving your teeth in unwanted ways. If a CBCT scan reveals that you have less than 50% bone support, anchoring a device to those teeth is clinically unsafe. In these cases, we pivot to alternative therapies like a Tongue Retaining Device (TRD) or coordinate with a specialist for bone reinforcement. This 2026 standard of care protects you from orthodontic relapse or tooth mobility that can occur with cheaper, unmonitored snore guards.

In Austin, a diagnostic CBCT scan for airway analysis typically ranges from $250 to $500. While this is an upfront investment, it can be a massive financial win compared to the $40,000 cost of full-mouth implants required if a device is anchored to failing bone tissue. At Enamel Dentistry The Domain, located near Rock Rose and Burnet Rd, we make this technology accessible:

While iTero digital scans are great for showing the alignment of your teeth, they cannot provide information on the bone structure or your airway. To safely treat sleep apnea, we need to see the underlying bone structure that iTero misses.
If you fall below the 50% bone support threshold, we will recommend alternative treatment options. This could include tissue-borne appliances or a referral for a sleep apnea-focused gum graft before your treatment begins.
