Therefore, the present invention relates to a fixing device for artificial tooth processing that can be processed without producing a separate model for milling work.

In general, teeth not only allow food to be consumed, but also affect the pronunciation of language for communication.

Therefore, the loss of teeth not only makes it difficult to eat food, but also affects aesthetic pronunciation, thereby replacing the role of artificial teeth that can restore the function of teeth.

In this method of artificial teeth, the implant is fixed to the hardest bone of the patient's gum and the prosthesis such as crown is mounted.
