Description

{METHOD AND APPARATUS FOR SIMULATIING OF TEETH TREATMENT}

The present invention relates to a simulation method and device for dental treatment.

Generally, dental treatment includes treatment methods such as root canal treatment, orthodontic treatment, or implants. Among these, the implant treatment method refers to a replacement for human tissue when the original human tissue is lost, but in dentistry, it refers to the transplantation of artificially made teeth. This is a procedure in which a fixture made of titanium, which is not rejected by the human body, is planted in the alveolar bone where the tooth has fallen out to replace the lost tooth root, and then an artificial tooth is fixed to restore the function of the tooth.

Implants are a semi-permanent procedure that does not damage surrounding tooth tissue and has the advantage of providing artificial teeth that are almost identical in function and shape to natural teeth.

For implants, it is necessary to check whether the overall procedure plan is appropriate by virtually selecting artificial teeth in advance through computer simulation and arranging them at the expected placement location before performing the procedure.

Conventional simulation methods for dental treatment suffer from a decrease in efficiency during actual dental treatment because simulation is performed only in a uniform manner without considering the patient's dental condition.

Additionally, the prior art has a problem of not being able to intuitively display images of the patient's dental condition and simulation results desired by the user.
