It has been confirmed that the value of three-point flexural strength after 7 days of immersion in water at 37ºC is 240 MPa and over, conforming to the standard JDMAS 245:2017.
Breaking strength of a crown shape was tested assuming use on a molar. GAMMATHETA has a breaking strength approx. 1.7 times that of BLOCK 2. Moreover, it has been confirmed that the value significantly exceeds the assumed value for the maximum occlusal force of molars, 1280 N, approx. 130 Kg.

Since GAMMATHETA is more highly filled with inorganic fillers than BLOCK 2, it has high stability against water; also absorption and dissolution amounts are greatly reduced.
GAMMATHETA’s radiopacity and fluorescence are equivalent to BLOCK 2.
Since GAMMATHETA is polymerized to a high degree by heat processing, its excellent staining resistance is confirmed; it is hard to discolor in the long term and long-term endurance of aesthetic quality can be expected. This has been confirmed by studies comparing extracted teeth of bovine (Enamel and Dentine).
GAMMATHETA is less likely to be worn away. At the same time, it is less likely to damage the opposing tooth, and the problems caused by losing occlusion balance are rendered less likely to occur.
