PROBLEM TO BE SOLVED: To provide a dental model capable of providing an experience of examining mobility of a tooth.SOLUTION: The dental model is provided with a model tooth 30 having a crown part 31 and a root part 32, and an alveolar bone part 10 having an alveolar bone root arrangement hole 10A, the alveolar bone root arrangement hole 10A being composed of an alveolar bone hole inner wall 101 and an alveolar bone hole bottom part 102, the root part 32 being disposed in the alveolar bone root arrangement hole 10A, the model tooth 30 being movable with respect to the alveolar bone part 10. The model tooth 30 is enabled to move with respect to the alveolar bone part 10 due to a structure in which the root part 32 has a root bottom part 322, the root bottom part 322 and the alveolar bone hole bottom part 102 are separated from each other, a first elastic member S is disposed between the root bottom part 322 and the alveolar bone hole bottom part 102, and the first elastic member S is deformable so as to allow a change in distance between the root bottom part 322 and the alveolar bone hole bottom part 102.SELECTED DRAWING: Figure 6 |
