BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an image generation system for an implant diagnosis and a method of generating the same, and more particularly, to an image generation system and method for an implant diagnosis used in diagnosis and treatment planning of a dental implant.

A dental implant is a substitute that restores when the original tissue is lost, but in dentists it refers to a series of procedures for implanting an artificial tooth.

In order to replace the missing root (root), a tooth fixture, made of titanium or the like, which has no rejection to the human body, is planted in the alveolar bone that has exited the tooth, and then the artificial tooth is fixed to restore the function of the tooth .

In general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants do not injure the surrounding dental tissue, and they have the same function and shape as the natural teeth, but do not have cavities. Therefore, they can be used semi-permanently.

The artificial tooth procedure (also referred to as an implant or implant procedure) varies depending on the type of fixture, but after a predetermined drill is used to puncture the fixation position, the fixture is placed on the alveolar bone to perform an artificial fusion to the bone, After the abutments are combined, it is common to finish the abutment with a final prosthesis.

Dental implants enhance the function of dentures in single-tooth restorations, as well as in partial and total toothless patients, improve the aesthetic aspects of dental prosthesis restoration, and further dissipate excessive stresses on the surrounding supporting bone tissue It helps to stabilize the dentition as well as sikim.
