 Hi, Dr. Jared here. Just want to share with you another tip on space maintainers. Here is a situation where you may look at that mouth and see this is something you want to do an anson, but if you actually look at this case, we don't have the first molars erupted enough to fit orthodontic band on. So you may have to consider a reverse band and loop in this case or a 3D printed band. If you want to learn more about 3D printed brands and space maintenance, take our course pediatricdentalce.com on simple space maintenance.
