Pivot NL DPAs are made using compression molding, a process that involves taking firm strips of natural rubber and extracting the latex protein. This process allows Pivot’s latex-free cup to maintain the handling characteristics of natural rubber. Pivot NL cups are designed to be softer, more elastic and with improved concentricity allowing them to spin truer, reducing splatter and providing a more predictable polishing edge. That’s why Pivot NL cups are preferred by 4 out of 5 dental hygienists. In contrast, the majority of manufacturer use injection molding, a process that involves liquefied plastic and forming it into cup shapes. Plastic is stiffer, less elastic than rubber and it can lose its concentricity once it’s splayed into the sulcus or pushed interproximally. This often results in increased splatter, wrist fatigue and “wobbling like a bad tire.”
