The rat maxillary molar has 5 roots, especially the mesial root is long and the bifurcation angle is large, the root is easy to break and the extraction is difficult.
The clinical tooth extraction device is large and is not suitable for the intraoral tooth extraction of rats. Because the teeth of the mice are short, the teeth can be directly pulled out by the probes, but the probes are not suitable for pulling out the molar teeth of the rats, and the mice often take a long time and are difficult to pull out. The rat dental crown is directly held by a needle holder or forceps, which easily causes fracture of the dental crown or fracture of alveolar bone. Lack of a fine practical tool may cause damage to the alveolar ridge and adjacent teeth of rats and easily lead to root breakage, affecting further experiments. It is therefore desirable to design an effective dental extraction collar.
