Yes. The mode of connection between dental implant andabutment is among the contents that should be specified in theproduct structure and components. The modes of implant-abutmentconnection is mainly classified into external and internal connectiontypes, and can also be classified into internal square connection.external hex connection,external octagon connection,internalhexagon connection and Morse taper connection by geometricshapes. Based on different modes of connection, the administrative counterpart should respectively carry out the relevant studies on theverification of system compatibility such as the taper fit of internalconnection of the implant, the fit clearance between the implant andthe abutment, the torsional property, the tightening torque and thefatigue limits.
