False tooth repairing method and equipment

Technical Field

The invention relates to the technical field of orthodontics, in particular to a false tooth repairing method and false tooth repairing equipment.

Background

Three-dimensional printing (3D printing), which is a technique for realizing the physical structure of an object by layer-by-layer printing using materials such as powdered, linear, or block plastics, wax, or metal based on a digital model file (typically an STL or CAD file), is also called additive manufacturing, and covers various different types of techniques, such as fused deposition, laser sintering, photo-curing, binder jetting, and the like.

At present, casting is traditionally used. Firstly, using wax-type material to make patient bite, casting wax-type dental model, then using ceramic shell to cover it, heating and utilizing high-temp. to melt wax-type material, injecting molten metal material into the above-mentioned material, cooling so as to obtain the invented wearable metal tooth.
