The Essix Retainer is a popular retainer for the extremely appearance-conscious patient. Fabricated by thermo-forming a thin sheet of Essix material over the entire arch, this retainer is made of a tough, stain and abrasive-resistant clear acrylic that has the light-reflecting properties to make teeth appear brilliant when the retainer is in place. The appliance covers the buccal, labial, and lingual surfaces and extends onto the gingival tissue. Note: If you have a specific finish in mind, please provide a detailed description when ordering this appliance.
