The Perfmaster is a carving instrument for fast and time saving modulation of light curing tray material, e.g. MEGATRAY.
The wafers can now easy cut and contoure on the plaster model, because of the sickle form of the carving instrument. The additional round stamp of the instrument is suitable to make a perforati- on of the final modulated tray. This perforation makes mechanical retention possible and reduce the working time on the finish cured tray. The additional use of an adhesive for impression material is not required.
