Over the years, one of the laboratory procedures that has created stress and required extra time has been investing and divesting partial dentures, especially because there was always the possibility of damaging the frame or breaking a clasp.
I've developed a technique that makes this process easier. I use a putty matrix made from Heraeus' Palapress vario, a rapid-cure acrylic for partial and full dentures. It has the technical properties of heatcuring acrylic, and color stability thanks to an ammon-free acceleration system. When cured, the material has less residual monomer than heat-cured acrylic (see graph below).
Palapress vario features a complex blend of cadmium-free, nontoxic pigments that are esthetic and seemingly disappear in the patient's mouth. It offers a great working time, flows into the smallest saddle areas bubble free, and is easy to polish and for the patient to keep clean.
