The objective of this study is to investigate the effect of different luting agents on the fracture strength of Turkom-Cera™ all-ceramic copings.

Methods and Materials

Standardized metal dies were duplicated from a prepared maxillary first premolar tooth using non-precious metal alloy (Wiron 99). Thirty Turkom-Cera™ copings of 0.6 mm thickness were then fabricated. Three types of luting agents were used: zinc phosphate cement (Elite™), glass-ionomer cement (Fuji I™), and a dual-cured composite resin cement (Panavia F™). Ten copings were cemented with each type. All copings were cemented to their respective dies according to manufacturer's instructions and received a static load of 5 kg for ten minutes. After 24 hours of storage in distilled water at 37°C, the copings were vertically loaded until fracture using an Instron Universal Testing Machine at a crosshead speed of 1 mm/minute. The mode of fracture was then determined.


Statistical analysis carried out using analysis of variance (ANOVA) revealed significant differences in the compressive strength between the three groups (P<0.001). The mean fracture strength (in Newtons) of Turkom-Cera™ copings cemented with Elite™, Fuji I™, and Panavia F™ were 1537.4 N, 1294.4 N, and 2183.6 N, respectively.


Luting agents have an influence on the fracture resistance of Turkom-Cera™ copings.
