Wow Patrick, this stuff is fantastic. I cant help but play about with blender and try to copy what your doing. the youtube videos are a great help. Keep up the good work any chance of a screw retained implant bridge! over two stages one onto links then one not needing the links, possibly external hex. I know its asking a lot but from what you have done so far it should be a real brain teaser for you. Keep up the good work really impressed!!!!!!!!
