Traditional Diagnosis in Prescott Valley and Flagstaff

To provide effective treatment for sleep apnea, Dr. Goodwin first needs to confirm you are suffering from the disorder. In the past, patients needed to travel to an overnight sleep center to undergo a diagnostic study. Many patients felt uncomfortable sleeping in an unfamiliar setting, which could affect the test results or even delay timely treatment.

Our Diagnostic Approach

From diagnosis to treatment, our approach to care is designed to be comfortable and non-intrusive. Rather than send every patient to a lab, Dr. Goodwin utilizes home sleep testing equipment. This allows our patients to remain in the comfort of their own homes. Working closely with your primary care physician, Dr. Goodwin may recommend at-home testing or in some cases, that you travel to a sleep center. Typically, at-home testing is used for younger patients in good general health. The severity of your symptoms can also determine whether at-home testing is appropriate.

The MATRx Advantage matrx device

Dr. Goodwin is proud to be one of less than 100 dentists who are MATRx trained and certified. This advanced method of pre-testing is used to determine whether a patient will respond well to an oral appliance. Oral appliances are used to gently bring the jaw forward during sleep, tightening loose tissue and opening the airway.

MATRx consists of a test carried out at a sleep center. During an overnight stay, the patient wears a temporary oral appliance under the supervision of an analyst. This technician will evaluate the patient’s response in real-time. This provides an extremely accurate way of testing their response. Once this information is compiled, Dr. Goodwin can determine whether an oral appliance will be sufficient to restore your quality of sleep.

Your Treatment Options

Oral appliances offer a comfortable and minimally invasive alternative to a continuous positive airway pressure (CPAP) machine. Although CPAPs are effective for some patients, non-compliance is widespread. MATRx not only evaluates how effective an oral splint will be for you, but it can also show precisely how far the lower jaw needs to be brought forward. The need for ongoing testing is minimized, as well as adjustments to the permanent, customized appliance.

Schedule an Evaluation

Often, the first steps towards a diagnosis is simply discussing your concerns. Dr. Goodwin views the initial consultation as an important part of your treatment plan. We will take all the time you need to answer questions and ensure you are fully informed. Contact us today to schedule an appointment and learn more.
