QUESTION: Hello...
I want to ask that can primary impression effect bite registration.
I an practicising from 1 denture pt was satisfied well...
But from 2-3 months every denture patient was a failure..due to occlusion not  achieve ..i have change only primary impression method  from compound to alginate only...trial was repeated twice in some patients..still they fail.. can possible?
Or i was wrong somwhere else

Well this is a lengthy subject. Short answer would be yes; primary impression could affect bite registration. There could be several reasons for that including tray used, time taken to pour impressions, base plate used and type of bite registration used.
Are you using alginate as your final impression. If you are then you might want to consider using more accurate material.
Hope this answers your question.
