Q

5 steps to ideal function

A
  1. Determine position of condyle
  2. Determine the vertical dimension (affected by desired overbite and overjet)
  3. All teeth should touch in CO
  4. Eliminate posterior tooth contact in eccentric movement
  5. Make sure teeth are in harmony with function (NM envelope of function)
