any one ever use an occlusal guide?

You can measure interocclusal distance by using vinyl-polysiloxane and an Iwanson gauge. I wouldn't buy this personally because it's another instrument to add to my overfilled tacklebox.

 

I go to Temple and we get those things in our kit but I have never used it. I agree with UCF, a VPS matrix or measuring your provisionals with an Iwanson gauge is the better way to go. These methods give you more information about your prep than the occlusal clearance guide anyways. VPS can be pricey though.

 

I've used the guides, and they work fine. VPS and Iwanson works, but once you guys graduate and have to pay for that VPS, you may change your technique.
