Abstract: A dental indirect vision training apparatus is provided devised to assist in the development of indirect vision eye-hand coordination among dental students. A prosthetic jaw member is rotatably positioned upon a base stand and each of a maxillary and mandibular denture is attachable into the jaw member in positions appropriate to resemble human anatomy. Target members disposed upon each of the maxillary and mandibular teeth enable practiced movements with dental tools wielded to contact the target members by indirect sighting via a manually coordinated dental mirror. Dental students thereby learn spatial relationships and eye-hand coordination interior to an oral cavity while visually apprehending images reflected at angles atypically experienced in everyday life. Indirect vision and coordinated movements are thereby explored, strengthened, and developed.

Abstract: The invention provides a dental model with an artificial jawbone with cavities, at least two artificial teeth, and interfaces each connecting a corresponding tooth to the jawbone such that it extends upwards from a corresponding cavity. To enable movement of the teeth relative to the jawbone and relative to the other teeth, the teeth are connected to the jawbone via interfaces which are more elastically deformable than the teeth and jawbone. In this way, a realistic dental model can be made in a very simple and cost efficient manner, e.g. in an SLS process. The invention further provides a method of making the dental model.

Abstract: The present invention relates to a tooth which is used in a dental arch model with which dental students can experience dental works in the oral cavity and practice treatments. More specifically, the present invention relates to a tooth composition for formation trainings such as abutment tooth formation and cavity preparation. Since conventionally used dental arch models have a grinding sensation different from a natural tooth, dental students having completed formation trainings such as abutment tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different grinding and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from a natural tooth in grinding sensation including slipperiness and easiness in grinding.
