well I bought some of those Chinese teeth off ebay when the denture lab guy moved out of our area, I dont do removable but I have the equipment and know-how and Im the only lab around thats not a denturist so I help out a couple of local regulars who have emergency flippers or repairs, easy $$ but, well you know...I do find they are really handy for stint designs and when I gotta dup a distal extension case for surgical stint...very handy..
