It has been claimed that if a “phase” (deviation in the flush terminal airplane) occurs on account of carious lesions or other disturbances, a bent to interfere with the event of regular occlusal relations with the everlasting first molars is evident.
This framework serves to equalize the forces of effects in occlusion.
