Abstract
The fracture toughness of five different resin-based inlay/onlay mater ials 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 dire ct and indirect techniques. Tests were performed immediately, after 1 day, 1 month and 3 month time intervals. Also, fractured surfaces of s pecimens were observed using SEM photographs.
