For deep canal impressions, I was trained to have patients talk as well
as open and close their jaws in order to obtain jaw movements in the
impression. There have been recent articles on enclosing two impressions
per ear (one with jaw closed, and one with jaw open). Is this better than
one impression where the person opens and closes their jaw while the material
is setting? What are some thoughts from others who do a lot of CIC fittings?
