Simultaneously prepares nips clutch surface approximately 1-2 mm the gap,center with when non-center clutch position nips the clutch surface gap to be supposed to be consistent. But the pate preparation cup shoulder,is lower than yin under approximately 0. 5 mm slighay. After each preleration should slide,not incisiye border and rough surface. Tries Dai Quanguan,after not clinical symptom tack-dry. Results：One hundred and thirty-two example patients achieved the successful standard,28 example patiants achieved the change for the better standard, 1 example treatment defeat.
