The present invention relates to an isosorbide derivative compound represented by the following structural formula (1). [Structural formula 1] As a result, when a methacrylate group is substituted for a hydroxy group bonded to an isosorbide compound to remove the methacrylate group, it is possible to reduce damage due to contact with water when the filler is used as a dental filler, thereby reducing the shrinkage And the water absorption rate can be reduced, and mechanical properties such as compressive strength and flexural strength can be improved. |
