Peri-implantitis is the most common and intractable complication of dental implant-supported prothesis affecting its long-term success, and is one of the main reasons for implant failure. Due to the limitation of the research methods, the pathogenesis and pathological processes of peri-implantitis remain unclear. Animal models are indispensable tools to study the pathogenesis of diseases. With the advances of the dental implants, the peri-implantitis mouse model has been used in experimental research. This paper summarized recent studies from the following five aspects: the advantages of the mouse model, the influence of mouse strain, the design of micro-implant, the way of implant insertion, as well as the induction of peri-implantitis, aiming to provide references and help for researchers. Compared with the large animal models of peri-implantitis, the mouse model of peri-implantitis is more flexible in use. Lower costs can better control the sample number and shorter induction time can better control experimental duration. The completion of mouse genome sequencing and the progress of the genetic operating system also make the pathogenetic study possible. However, the mouse model of peri-implantitis still has some limitations. Limited by the small size of mouse oral cavity, implant insertion surgery is technically demanding, and complex surgeries are even more challenging. Moreover, due to short history of the peri-implantitis mouse model, its corresponding technical theories such as implantation methods, peri-implantitis induction methods and so on are not unified yet and still need further research and development.
