1. A method for producing an adhesive bond, comprising the steps:
curing (S101) a light-curing adhesive material (103) by light;
detecting (S102) a degree of polymerization of the adhesive material (103) to determine if a specified degree of polymerization is reached that is required to achieve adhesion to a bonding site; and
wherein the determination of the degree of polymerization is carried out by an ultrasonic method using a sound velocity measurement, a sound resonance measurement and/or a sound level measurement; and
terminating the curing if the measurement falls below a predetermined threshold value.
