    Patent number: 6447290
    Abstract: The protective element includes a flexible, cotton flannel base portion and a wax portion which impregnates the base portion to produce a combination article, wherein the wax portion is formulated so that the combination article is sufficiently flexible to prevent the wax portion from cracking away from the base portion at room temperature, and further such that the flexibility of the article increases sufficiently when the article is warmed by placement in the mouth to permit conforming application of the article to the dental appliance, and further such that the article remains in place against the dental appliance during use.
