Aims: Metal-porcelain restoration is currently the most popular restoration that can be used for the anterior teeth. However the collar coping design on facial margin gingiva causes dark and shadowed zone in gingival, which is called "Umbrella Effect". This situation can overcomed by using collarless coping design. But this coping design has weaknesses such as decrease the fracture resistance of retoration. In some previous studies, the type of coping material can also affect fracture resistance. this study aimed to determined the effect of the coping material tipe and collarless margin design on the fracture resistance of restoration. Material and Methode: A total of 24 samples of metal-porcelain restorations from two material type and design were fabricated and cemented on 24 metal dies. The study was divided into four groups; Group A with Ni-Cr and Full Metal Collarless, Group B with Ni-Cr and Modified Metal Collarless, Group C with Co-Cr and Full Metal Collarless, and Group D with Co-Cr and Modified Metal Collarless. The measurement of fracture resistance was carried out using universal testing machine (Torsee UTM AMU-10, Tokyo, Japan) at a crosshead speed of 0.05 mm/minute. Loading point was applied at an angle of 45° until the porcelain layer fractured.
