Teh zOrtho Gray resin is designed specifically for the main applications of the dentistry and orthodontics sector. This resin meets all the mechanical properties that this type of pieces needs: high tensile strength, high percentage of elongation before breaking, resistance to bending and resistance to impact. To the set of all these properties it is necessary to add the matt gray finish that this resin presents, which makes the ZOrtho Gray an ideal material for the manufacture of dental prototypes with a great dimensional precision. A very interesting application is the manufacture of jaws, previously scanned to patients, to easily verify the state of the denture and perform tests on them.
