ABSTRACT
BACKGROUND: Composite resin functions as a practical resin restoration material with beautiful outlook, modifying its mechanical properties has become a hot spot in research.OBJECTIVE: To prepare resin specimens with two kinds of inlay curing machines: CERAMAGE and TESCERA, and to compare the mechanical properties of these specimens.METHODS: The resin specimens supporting two machines were cross-matched with these machines and then divided into four groups: Group A was Tescrea resin prepared with TESCERA machine; group B was Tescrea resin prepared with CERAMAGE machine; group C was Ceramage resin prepared with CERAMAGE machine; group D was Ceramage resin prepared with TESCERA machine. The standard specimens were determined for compressive strength, hardness and flexural strength.RESULTS AND CONCLUSION: The compressive strength and hardness in group A were higher than those in other three groups,and group B exhibited higher compressive strength and hardness than groups C and D (P < 0.05). The flexural strength in groups C and D was higher than that in groups A and B (P < 0.05), there was no significant difference between groups C and D, neither betweens group A and B. The experimental findings indicate that TESCERA inlay machine and Tescera resin achieve the optimal mechanical properties.
