Thank you for the interesting presentation.
Especially, I am impressed that the attractive force of the optimal model shows about 10 % larger than that of the normal model for the inclination angles up to 5 degrees.
Would you tell us the insight from the view of clinical use ?

Thanks for your question. As for the attractive force is larger in the optimal model than in the basic model, until the inclination angle of attractive surface is 5 °. However, when comparing the reduction rate of the attractive force between the optimal model and the basic model, the optimal model is larger. Therefore, the magnetic attachment designed with the optimal model has a narrow tolerance range for displacement, and it is considered that caution is required when clinically used.
