Audience, do you have any question or comment?
At the beginning, I ask to the authors, now.
Each bending strength of ACRON was larger than that of PRO IMPACT in Fig. 6, however, each energy of rupture was the opposition in fig.7. I could not find the information of the elongation (flexure) of both resins during 3PB test. Why did the phenomena occur in 3PB? On the other hand, in the 4PB, when each bending strength of PRO IMPACT was larger than that of ACRON, the energy rupture of PRO IMPACT became larger, too. Could you explain those reason?
Thank you for your question.
In both of the 3PB and 4PB, the energy of rapture of PRO IMAPCT was larger than that of ACRON, it said to be that PRO IMPACT was flexural material. In this experiment, for 3PB, the flexural material(PRO IMAPCT) escaped the force, it was assumed that the value of the bending strength of PRO IMPACT was reduced. While in 4PB, since one side was fixed by copings, without releasing the force, it was assumed that the value of the bending strength of PRO IMAPCT was increased than that of ACRON.
