Semi-permanent dual-cure material for cementation of crowns and bridges on implant abutments and natural teeth stumps, when there is a need for: 3 formation of gums and modeling gingival papilla 3 periimplantitis treatment 3 reconstruction (and stabilization of the mouth) 3 repairs or color (modification). A completely new idea of the semi-premanent bonding: no chemical adhesion [0 MP a] is compensated by the controlled expansion of cement. This ensures optimal bonding, and above all safe removal of the restorations without damaging them.
