[Bending strength of UV hardening composites]

Mechanical firmness of 4 UV hardened composites was estimated by the bending test according to DIN 13922. Bending strength and breaking point lie between 70 and 120 MPA and 0.5 and 0.25 mm compared with 110 MPA and 0.13 mm for Adaptic. The results show that the combination of filling substance and UV irradiation is well balanced.
