The replaceable bone pieces of this model help to improve the efficiency of the model, but the means for fixing the alveolar bone also limits the recycling of the model to some extent. Meanwhile, the model is only suitable for teaching periodontal disease or dental implantation, has fixed teaching functions, and cannot be used for more dental teaching, such as tooth dividing, wisdom tooth extraction, bone grafting, wound area treatment, postoperative suturing in gum tissues and the like, which are performed on hard tissues.
