Any protips for helping my brain figure this out? We started working exclusively on maxillary teeth in operative this semester. We are doing Class II's on #14 right now and I am struggling to work while the mirror is in the mouth - I feel like I'm blocking it with the hand-piece or I don't have enough space. I've been told to rotate the mirror around the tooth to see different angles. I keep trying to look in with direct vision and then at the end of class my back is really feeling it. Can't imagine doing this for the next 30 years without a serious spine condition..
