Open or closed mouth impressions

post #1 of 5
Thread Starter 

I was checking sources for custom reshelling other than In Ear Customs, when I noticed on Cosmic Ears' website that they are pretty emphatic about requiring open-mouthed impressions be taken for their products. Since that was different from what I thought I remembered the recommendations of In Ear Customs being, I  reviewed the directions I received from them for taking my own impressions, and sure enough, they recommended a closed-mouth impression "if you plan on wearing them a lot," (which I do). They say that an open-mouthed impression will make a larger impression (which makes sense) and will therefor be more fatiguing, and is only recommended when they will be used with an open mouth, i.e., a vocalist. I'd be very interested to hear what those of you with ciems think, and what you remember from the impression process, especially if done by an audiologist

I went open-mouthed and they still can be a bit small.  Another thing to consider is placing the dams 2mm deeper than typical ( Westone recommends this ) so when the manufacturer sheers off the end it still passes the 2nd bend of the inner ear.

 

A bite block is the only way I would ever have it done.
