Custom dental tray
First Claim
1. A dual tray assembly, comprising:
- a carrier tray configured generally to conform to a patient'"'"'s teeth; and
an inner tray with a configuration which extends over the teeth that removably nests inside the carrier tray making a dual tray assembly;
the inner tray being made of a thermoplastic compound including 50% to 80% by weight polycaprolactone and 10% to 40% by weight of ethylene vinyl-acetate.

Abstract
A dual dental tray assembly is provided which includes a pliable resilient outer dental tray using a pre-formed thin inner tray of thermoplastic material that nests inside the pliable outer tray. The two are heated to between 145°-160° F. During this time the inner tray is more formable, allowing for the inner tray to be accurately formed over the patient'"'"'s teeth. The outer tray also prolongs the time during which the inner tray is moldable. The outer tray also operates as a seal with the gums to create a better vacuum created by the patient'"'"'s sucking. Thus, the inner tray, once formed and cooled, becomes hard and flexible again and provides a thin hard dental tray as accurate as dental trays produced by dentists in their labs on models. The thinner, hard dental tray can then be used for dental treatments including bleaching, fluoride applications, and other dental operations, including provisional crowns and other dental work. The outer tray is usable for fluoride gel treatments.
