Early loading

Refers to the time of applying force on an implant after initial placement. This term mostly is used in oral surgery/dental implantology. The prosthesis is brought in function earlier than the conventional healing period. Early loading may be applied, if preconditions are good or optimally.

Delayed loading

Refers to the time of applying force on an implant after initial placement. This term mostly is used in oral surgery/dental implantology. The prosthesis is brought in function after a certain healing period. The healing period may be very different, depending on some factors like general predisposition, diseases, tissue health, intensity of use, cooperation.
