ABSTRACT:
A customized dental tray comprising ULDPE is formed using a person's own teeth as a template, or using a stone model of the person's teeth. A preformed dental tray or sheet comprising ULDPE is heated to become plastically deformable and placed over at least a portion of the person's teeth in order to form an impression of the person's teeth and yield an intermediate customized dental tray. Upon cooling sufficiently, the intermediate tray is removed from the persons' mouth and trimmed as needed to yield a finished customized tray corresponding to the person's teeth. The performed tray or sheet preferably comprises ULDPE, which yields a highly flexible and resilient final tray, although they may also contain other polymers or blends. The customized dental tray is useful for teeth bleaching and other dental treatments known in the art.
