SELF-CUSTOMIZABLE DENTAL TREATMENT TRAYS

摘要

A self-customizable dental tray (150) usable in a dental application is prepared as follows: providing a barrier layer (151) in the shape of a dental treatment tray having a wall thickness of less than or about 1 mm; introducing a curable elastomeric material (161) onto an impression-receiving surface of the barrier layer (151); placing the barrier layer (151) having the curable elastomeric material (161) onto the teeth so that the curable elastomeric material (161) forms an impression layer; and allowing the curable elastomeric material (161) to cure so as to form an impression layer having a teeth-receiving surface with contours adapted to conform with the teeth, said impression layer having a wall thickness of less than or about 1 mm. Optionally, the barrier layer (151) is a liner that can be separated from a support tray that provides a tray shape to the liner.
