Sorry to resurrect an old thread, but I have a question for you guys that are doing these. Are these actually done in the mouth or do you use a model? I've watched a couple videos, but they're more from a clinician perspective. So do you guys use a stone model to work on? It seems like you'd have to, particularly when filling the spaces in between the drilled out holes in the denture and the temporary abutments. I can't imagine injecting light-cured resin right into the patient's mouth. Can anyone clarify for me?
