Angle of Function
This animation focuses on the practical consequences of a patient's system permanently learning a reduced "angle of function".
If you restore to what we'll call the original "angle of function" (the red angle in the pictures below) after the patient's system has become accustomed to a smaller (blue) angle with their worn teeth, the patient is likely to keep moving the jaw to conform with the smaller angle. Restorations will be destroyed.
To avoid this issue, build up the back of the upper front tooth so that the new angle of function matches the worn-tooth angle of function - as explained in the following snapshots taken from the animation.

Solution - restore to the worn-tooth angle of function
