Three-dimensional finite element analysis is currently a mature and efficient method for biomechanical research. As a key method for constructing complex structural models and analyzing their mechanical properties, this method can be used to construct mathematical and mechanical models of implants, restorations and jaws. Then, multiple calculations and analyses can be performed under different constraint loading conditions to clarify the stress distribution characteristics of the constructed models. This article will systematically review the research progress and current status of three-dimensional finite element method in the field of implant crown restoration in recent years.
