Changes in mandibular masticatory movements after insertion of nonworking-side interference.

To investigate the influence of nonworking-side interferences on mandibular masticatory movements and signs and symptoms of dysfunction of the masticatory system, an experimental balancing-side interference was introduced in 12 healthy subjects for 1 week. The individual response to the interference varied substantially. However, some of the movement variables were significantly changed immediately after insertion, but an adaptation of the neuromuscular system to the interference was evident at the end of the experimental period.
