Ortotypo 4 is a type-4, extra-hard stone specifically developed for all orthodontic models. Characterized by its hardness, extra-fine granulometry, low expansion and fast setting time, Ortotypo 4 is compatible with all impression material and all products for the isolation of plaster against plaster.

Ortotypo 4 is often used with acrylic resins (both hot or cold polymerization processes) on an unaltered surface. It has low breakage risk. The working time can be adjusted with Time Out.
