1. A system for securing an implant to a bone during surgery, comprising an implant, a grout or bone cement comprising a composition that cures during the surgery, the grout or bone cement being capable of securing the implant to the bone in a cured state, and a sensor which imparts an energy wave in an acoustic range to the grout or bone cement and receives the energy wave from the grout or bone cement and monitors a frequency change in the energy wave to determine a cure state of the grout or bone cement and the sensor also being joined to a circuit and to an indicator that emits a signal in response to a current emitted to the circuit by the sensor.
