Lately my Doc's are bringing me crowns which are missing some of their tissue borders , they always after they prepare the tooth or even before , they take me an impression so i build for them temporary acrylic crowns , after they receive the temporaries , they grind/prepare the teeth / take impression for me the metal / and they glue the temporary crowns , after 7 days sometimes a bit more due to lot of work in lab .. i send them the metal crowns to check them ... the metals sit perfect in the mouth, they send back to lab and after 7 more days i send porcelain check before they send again back to lab for glazing . . .
The problem starts when i receive the crown for glazing .. after metal check was ok , the crowns with porcelain on them while doc is checking in mouth are missing in some places , it looks like the tissue moved away upwards and left space and the natural tooth is visible , or the abutment .. in most cases i redo the work , other times in minor problems like these i add porcelain in the missing spot .. You think the temporary crowns are playing a bad part here ? that why the tissue is changing in two weeks since the first impression for the crowns was made ? i know that the tissue is not welcoming the temporary crowns very well, a friend of mine recommended me to do temporaries with no contact with tissue even that the natural tooth/or the metal abutments remain visible during this two weeks period while the temporaries are in the mouth . .
