- the height of the upper and lower jaw dentures is secured on the plaster model using wax, and artificial teeth are embedded in the wax to form wax dentures (so-called artificial tooth arrangement).
- the wax denture is buried in gypsum and hardened, and a part where the wax flows out is formed, and then the wax is melted and poured out using hot water or the like.
- the lost wax method has many steps and takes time to complete, and the skill of a dental technician is required for its production.

That is, CAD / CAM is used as data from design to manufacture of a dental prosthesis, and finally the dental prosthesis is cut out using an NC machine tool based on the data. According to this, there are few processes compared with the lost wax method, and it is possible to manufacture a dental prosthesis in a shorter period of time than before.
- the denture base is cut out with a hard resin material compared to wax, and the concave portion provided on the hard denture base is made of ceramic or resin. It is necessary to insert and dispose a pre-formed artificial tooth and fix it with an adhesive. At this time, the artificial tooth may not fit properly in the concave portion of the plate denture prepared by cutting.
