If, in the pre-operative impression, there is a wall of impression material between the abutment tooth and the neighboring tooth, the assistant should use a hemostat to remove the excess impression material to allow the liquid temporary mixture to flow into contact with the neighboring tooth.
(34) The assistant points the tip into the hole in the preoperative impression that corresponds to the abutment tooth and fills the hole.
The assistant then eye-drops the monomer liquid into the powder, enough to create a thick, barely viscous--but not visibly powdery--acrylic/monomer mixture, which is then spatulated into the abutment tooth hole in the pre-operative impression.
