These caused a mass of waste of material.
It can be seen that material is saved 35089kg after being optimized, if the material is calculated by 6000yuan /1000kg, the cost 210 thousand yuan can be reduced.
It is visible that a large amount of raw materials will be saved in optimization design of structural and special attention will be surely paid by engineering field and developers.

Introduction Various materials such as stainless steel or titanium have been used to reconstruct human body functions lost from aging, illness, or accidents, and these materials have supported medical progress 1).
Notably, among those artificial materials, metal materials are still considered very useful in many medical devices, because of their excellent strength and toughness 2).
However, one of the challenges in using metal materials for dental prosthesis is aesthetics.
