Originating from the need for precision articulations, GNATHOSTONE® is manufactured using high grade gypsum with a controlled particle size, which results in smooth and dense modeling characteristics. The extremely low expansion, the dimensional stability over time and the fast working time ensure that vertical articulation methods in the mounting of models are properly carried out. These characteristics make GNATHOSTONE® the product of choice for the fixing of gnathologic tools. FIELDS OF USE: The mounting of models using articulation methods, the making of trimming bases.
