Abstract

Abstract: With the widespread use of dental implants,dental implants,orthodontic anchorage screws,jaw fracture fixation devices and other oral implants in clinical practice, the biomechanical properties of oral implants and the accuracy of implant placement have become one of the focuses in stomatology. These need to be clarified through a large number of in vivo and vitro experimental studies. However, in vitro study needs experimental models, and the establishment of standard experimental models is the basis for in vitro study. Therefore, it is necessary to find or establish experimental models that meet the standards. At present, there is no authoritative standard for in vitro studies of implants in the field of stomatology. The experimental models reported in the literature include gypsum, acrylic, and polyurethane. Among them, polyurethanes have been widely used in in vitro studies because of their similar properties to those of bone. Therefore, this paper summarizes the application of polyurethane experimental models in in vitro researches of oral implants, its remaining advantages, disadvantages and future prospects, hoping to provide a reference for the selection of in vitro models for future oral implant research.

Key words: Dental implant, Polyurethane, In vitro study, Experimental model
