Hello, everybody. Welcome to Quick Tips. In this edition, we're going to be talking about customizing your patient's envelope of function, which is a very important part of getting the anterior guidance right for your patients.
As you're looking at the lingual contour of provisional restorations, hopefully you are developing lines on your provisionals that provide evidence of posterior disclusion or anterior guidance.
Remember, if you don't get anterior guidance or posterior disclusion, then that is going to allow the back teeth to rub.
And if the back teeth rub, then we know that increases muscle activity and can create damage to the teeth, either by working them loose or by causing the teeth to wear. And make no mistake, a lot of the fractures we see are related to not having good anterior guidance or posterior disclusion.
But the question is, can we make the guidance too steep?
When the patient starts chewing and speaking and the mandible starts moving outside-in, is it possible to get those lines too steep so it's actually in the way of the functional path that the lower incisors travel outside-in?
