摘要：

The fracture toughness of five different resin-based inlay/onlay materials was investigated by means of critical stress intensity factor (K(IC)) using the SEN three-point bending test procedure (BS 5447: 1977). K(IC) values were determined from specimens prepared by both the direct and indirect techniques. Tests were performed immediately, after 1 day, 1 month and 3 month time intervals. Also, fractured surfaces of specimens were observed using SEM photographs.
