PowerPlus Sleep Appliance puts your lower jaw into your Physiologic Rest Position to open your airway and reduce or eliminate snoring. This increases your oxygen intake to equal a better night's sleep. We offer a thermal matrix material that enables each user to personalize their device with a custom impression. You will receive an impression kit and a return label to send the impression back to be fabricated. The custom impression process is a simple process that can be done in the comfort of your home.
