Progress of research on the design of implant-abutment interface
The stability of marginal bone level is an important factor in ensuring long-term good clinical efficacy of implantation.The design of implant-abutment interface(IAI)is of considerable importance,including whether undergoing multiple abutment disconnection,whether platform switching is used,connection type,connection torque,and connection material differences.These fac-tors can affect the micro gap and micro movement of the connection interface,which change the size of micro leakage and mechanical stability,thereby affecting the long-term clinical efficacy of implants.This article presents a detailed review of the progress of research on different designs in implant-abutment interface,in order to provide a theoretical basis for the selection and operation of abutments in clinical diagnosis and treatment.
