From Dr. Champagne
Many clinicians only evaluate malocclusions in a static position which means in maximum intercuspation. This is not the best way to make a diagnosis and this will probably increase the number of mistakes. Omitting to diagnose a patient dynamically by looking at the path of closure of the lower jaw from the position of first contact to maximum intercuspation opens the door to misdiagnosis.
A lower midline deviation in maximum intercuspation can be perfectly centered at first tooth contact and simply deviated by an occlusal interference. A pseudo Class III can be diagnosed as a Class III, when only upper incisor iclination was the problem. A subdivision malocclusion that is only a consequence of a narrow maxilla resulting in a deviation and only a dynamic examination will be able to demonstrate the cause of the problem. We have to take particular attention to TMJ dysfunction cases because their dynamic is erroneous. These cases need special attention to treat the TMJ dysfunction first.
Comment by Dr. Macdonald
For years we have been teaching deprogramming occlusion.
Leaf gauge or even Kois deprogrammer worn for a month then mounting in muscle mediated CR with facebow transfer to first tooth contact CR
AND IF MPI AND CR POSITIONS ARE DO NOT MATCH TAKE 2 CEPHS, one at MPI and one in CR. Also take vertical dysplasias number variance studies from these 2 as well as AP to help target your diagnosis.
