  • Cast orthodontic retainer system
    Patent number: 8827696
    Abstract: A cast orthodontic retainer system for reducing discomfort and improving durability. The cast orthodontic retainer system generally includes a palatal portion for positioning against the palate of a patient's mouth and a retention portion for extending across an anterior portion of the patient's teeth. The palatal portion of the present invention is fabricated of a cast metallic material, thus allowing for the palatal portion to be substantially thinner than the palatal portions of retainers in the prior art. In a preferred embodiment, the palatal portion of the present invention will be fabricated of a combination of cobalt, chromium and molybdenum (generally marketed under the trademark VITALLIUM). The palatal portion of the orthodontic retainer is preferably cast from the metallic material utilizing the “lost wax” technique of casting.
