Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a root canal treatment model for partial root resorption of deciduous teeth. Background Art

[0002] In the treatment of children's oral cavity, root canal treatment of deciduous teeth is a common clinical operation when deciduous teeth are treated.

[0003] However, on the one hand, due to the gradual physiological root resorption of deciduous teeth during the gradual development and eruption of succedaneous permanent teeth, it is very difficult to extract incomplete deciduous teeth and intact exfoliated deciduous teeth with pulp and roots. On the other hand, with the growth and development of children, it is impossible to directly observe the dynamic changes in the relative positions of deciduous tooth roots and permanent tooth germs in exfoliated deciduous teeth, which makes root canal treatment of deciduous teeth more difficult.

[0004] Complete root canal treatment of deciduous teeth requires a full understanding and study of the internal structures of their crowns, pulp cavities, roots and their relative relationships with permanent tooth germs. At present, there are few oral operation models for children in clinical teaching. Most of these oral operation models for children are for pit and fissure sealing, resin filling, pulp opening and conventional root canal treatment, and there is no clinical operation model specifically for root canal treatment of deciduous teeth during the mixed dentition period. Therefore, root canal treatment of deciduous teeth is very difficult for oral medical students and children's oral doctors with less experience.

[0005] Therefore, a clinical operation model for root canal treatment of deciduous teeth during the mixed dentition period is needed, which can truly simulate the real situation of root canal treatment of deciduous teeth that may occur clinically, and is beneficial for young doctors and medical students to repeatedly practice on an in-vitro model, while ensuring the quality of root canal treatment of deciduous teeth, protecting the permanent tooth germs.
