“I’m not sure where to start when vertical dimension is over closed and the teeth are all severely worn.”
If you’ve ever thought something along these lines, there are a few things that need to be cleared up.
One of the things that Dr. Dawson teaches us is that if patients have all their teeth and the teeth are worn, they have not lost vertical dimension even if the teeth are halfway gone. We know that as teeth wear there is an elongation of the alveolar process and eruption occurs. So the distance between the chin and the nose does not in fact change even in the case of extreme wear.
