Patent ID: 7004756

Claim:
A dental treatment device comprising: a pre-shaped, non-custom dental tray suitable for placement over at least one of a person's upper or lower dental arches, wherein the dental tray is formed from a thermoplastic material and comprises: a bottom wall having a substantially horseshoe-shaped configuration corresponding to at least one of person's upper or lower dental arches, a front side wall extending laterally from a front end of the bottom wall; a rear side wall extending laterally from a rear end of the bottom wall; and a hollow interior portion defined by the bottom wall, front side wall, and rear side wall; wherein the bottom wall, front side wall, and rear side wall are substantially devoid of structures corresponding to the size and shape of a person's unique dentition so that the dental tray is designed to comfortably fit over a plurality of differently-sized dental arches corresponding to different people, wherein the bottom wall, front side wall, and rear side wall have a thickness in a range of about 0.05 mm to about 1 mm and are flexible so that, when the non-custom dental tray is placed over a person's teeth, the tray can at least partially conform to the person's teeth during use in order to approximate the comfort and fit of a custom dental tray without the need to formally customize the tray; and a quantity of a dental treatment composition loaded within the hollow interior portion of the dental tray, the dental treatment composition being sufficiently thick so that, when the dental tray is placed over a person's teeth, the dental treatment composition will hold the tray over the person's teeth and cause the tray to at least partially conform to the person's teeth.
