“Would You Want This In Your Mouth”


If you remember in an earlier blog I stated that 80% of all dental impressions sent to labs are inferior and/or inadequate. In a continuing series I will be presenting real cases sent to dental labs by other dentists to help educate patients so they can make informed decisions concerning their dental health.

I have talked about why I don’t take impressions the same day I prep teeth because I want to be in control when I take the impression. I also take full arch impressions even for single crowns because I can properly articulate the opposing model and capture function. Unfortunately to save time and money, most dentists use “Triple Trays” which capture only 1/3 to 1/2 of the dental arch, are very flimsy and provide no functional movements. These Triple Trays in my opinion are sub optimal for quality dentistry and are only convienent and less costly for the dentist using them.  Most crown fees within a geographic area are very similar regardless of the dentist, materials and lab that they use. Why wouldnt you go to a dentist that pays attention to the details, uses the best materials and lab?

Triple Tray Impression

This was a triple tray impression sent to a lab for a single crown. The light body syringable material is not even properly set.  Margins of the prepared tooth are indistinguishable.

 Here is the impression poured in dental stone that the lab will use to fabricate the crown.

Notice the orange unset impression material  and bubbles on the model. I cant see one margin that the lab needs to finish the new crown.

Would you want your crown made from this impression?
