Research progress of animal models on orthodontic tooth movement

Orthodontic tooth movement animal models are important carriers for studying orthodontic tooth movement. Experimental animals that can be modeled include: rats, mice, dogs, rabbits, etc. How to select suitable animal models for different scientific problems is very important. Therefore, this paper reviews the types and characteristics of orthodontic tooth movement animal models, and focuses on the similarities and differences of rodent anatomy, modeling methods and considerations. It is found that there is a lack of unified modeling standards for orthodontic tooth movement animal models. Thus appropriate animal models should be selected according to actual needs.
