By now most everyone practicing Sleep Dentistry has seen or handled a nylon appliance such as the Narval by ResMed and the D-SAD by Panthera. These companies have introduced us to a “New World” way of viewing appliances that manage Sleep Apnea; the CAD-CAM 3-D Printer way. Using laser sintering to layer nylon in successive layers the 3D Printer creates the appliance from the inside out. This nylon polymer is quite remarkable to say the least. These appliances are definitely a “Game Changer” and it is worth while becoming familiar with their unique characteristics. There are a number of NEW NYLON APPLIANCES to be available shortly. Read about the X3, the Oventus and the DDSO Nylon appliances in our new updated eBook. Also, we have added a section on the CAD CAM Milled Acrylic appliances.
