Periodontal lesion model information base established by digital technology and teaching method thereof

The invention discloses a periodontal lesion model information base established by a digital technology and a teaching method thereof, according to gingiva and alveolar bone absorption degrees, iconography and intraoral scanning data of different types of periodontal lesions are collected, digital information processing and classification are further carried out by using software according to tooth positions, and a periodontal lesion digital information base is established. The teaching method comprises the following steps: (1) clinical information is collected; (2) a doctor screens digital information close to the actual condition of the oral cavity of the patient from the periodontal lesion digital information base, and a model is printed through 3D printing equipment. Teeth, gingiva and alveolar bones are made of printing materials with different hardness; and (3) a periodontal lesion model which is highly matched with the condition of the patient is printed by utilizing 3D printing. According to the metho
