ABSTRACT:
A dental condensing instrument having an elastomeric tip of sufficient size to surround the margins of a prepared cavity, which will yieldably urge the flow of soft restorative materials inside prepared cavities to improve their adaptation to cavity walls and margins without the introduction of deleterious air voids therein. When hand pressure is applied, the tip will not only seal said margins, but also apply a steady, isostatic condensing force upon said materials.
