Thanks Dr.Bryan Kariya. It was short and good Crown and Bridgge module work flow. the Crown and Bridge Module can be Improved. One thing is when the software pulls the placed crown to the margin and deforms the anataomy of the crown. and it is difficult to edit the surface of the crown with add/remove or smooth or local deform tool, to a more anatomical and esthetic crown, specially in the anterior bridge, which is accetable when it is printed or milled in zerconia, so minimum or no adjustmets are necessary. then the digital work flow is justifiable. 99% of the crown and bridge should be completed in the software, with good anatomy, not after milling it or printing it. Any way it is a very good software for implant planning and guide making. but incomplete for Making Good Crown and Bridge work for milling. For making Provisional it is so so. Thank you Blue Sky Bio for providing Crown and Bridge for Free.
