Abstract
Abstract A packaged dental article includes a dental appliance that is precoated with an adhesive. The adhesive is in contact with a flexible film having a low adhesion surface. The film is secured to a container at a location spaced from the appliance so that the film tends to peel away from the adhesive when the appliance is removed from the container in order to inhibit separation of the adhesive from the appliance. The container has a sidewall with a recess that engages a carrier to hold the container, and the carrier is flexible to permit the container to be inserted into or released from the carrier when desired.
