A process of applying at least one dental element to a patients arch employs a device having a support tray shaped to fit to at least a portion of a patients dental arch. A formed, liquid-soluble material (such as a thin starch layer formed from a starch sheet) is supported by the support tray and holds at least one dental element in a location for allowing an exposed surface of the at least one dental element to be applied to a patients dental arch. Afterwards, the support tray is removed from the liquid-soluble material and the liquid-soluble is removed by dissolving it in a liquid, such as water.
