The present invention relates to a wax carving model for practicing a tooth shape, and more particularly, to a wax carving model for practicing tooth form which can effectively perform tooth shape learning and can be safely practiced, and a manufacturing method thereof will be.

An anatomical knowledge of tooth morphology is essential for the production of artificial teeth to restore or replace defective teeth or dysfunctional teeth in dental or dental laboratories. In order to reproduce and restore functional and anatomic tooth-shaped teeth, dentists and dental technicians are able to reproduce their teeth through repetitive teeth-type exercises on 28 teeth in the oral cavity.

The tooth-type carving model, which is usually used for tooth form practice, is applied to the tooth form practice using the commercial step-by-step tooth form carving model as a sample. However, the learner uses the model of each step to form the intermediate step tooth form There are many difficulties in doing so. The reason for this is that in order to explain each step in detail, a more detailed intermediate-stage model is needed. It is difficult to realistically realize that the number of models is too large to produce a detailed intermediate-stage model for oral teeth.

Also, it is not easy to implement the intermediate stage model that the practitioner must produce because the stepwise model that is currently commercialized starts with a rectangular block and the outline of each step is learned.

In addition, the material of the model used for tooth form practice is mainly used in plaster, but the plaster is very hard and difficult to be scratched. The tool used for sculpture is very sharp and there is a great risk of safety accidents during learning.
