Abstract
A temporary dental cement composition temporarily affixes a dental prosthesis or appliance to a tooth or other dental substrate. The dental cement includes a mixture of: (i) an ion leaching agent; (ii) polycarboxylic acid; (iii) sugar; and (iv) water. The sugar is added in a sufficient amount that the ion leaching agent and polycarboxylic acid form a hardenable adhesive having an adhesive matrix which forms a relatively weak, temporary bond, as opposed to a permanent bond. The temporary cement composition is compatible with subsequent deposition of typical bonding materials, such as resin luting agents as well as non-resin permanent cements.
