So this is a funny story. We as dentists may not be familiar with a primarily lab focussed company DOF. DOF sells and makes mills, lab scanners, face scanners and distributes ExoCAD. I have had a slew of digital dentures and wanted to try out their scanners with my cases, so they generously let me borrow a scanner. On my way I get a text from Josh Townsend, their VP who asked if I could take an impression there at the warehouse of an employee’s Dad. He was visiting from Romania and split his partial. Hey, haven’t take a full arch PVS since dental school, but lets give it a go! I wanted to scan the impressions in the impression scanner, but due to his extreme perio, the light of the scanner couldn’t reach the teeth. Ok, lets pour it up. Negative. The teeth were too long and kept breaking. Enter the CBCT. You can scan impressions in your CBCT and convert them to STL in Invesialius. Not super accurate, but I just needed the incisal edges of the teeth.
We got a good match between the scans. In ExoCAD I clipped away the gingiva from the CBCT scan so that I could take advantage of the detail in the DOF scanner. The partial was designed and printed by Arfona with the rPOD FDM Valplast Printer!! The teeth were milled PMMA. Just a little occlusal adjustment!
We play with Invesalius and CBCT to STL scans at the 3D Printing Party! Come to Austin Oct 12 and 13 for two pays of printing fun!
