The biggest difference of monolithic zirconium from normal zirconium core materials is that it is not damaged by contact with saliva directly in the mouth environment and is more aesthetic than normal zirconium material. They can be used in one piece or on chewing surfaces where the chewing force is the highest, without the need to process the less resistant porcelain material on it.
In zirconium core materials obtained from normal zirconium blocks, porcelain should be completely processed on it and not open to the mouth environment.
