Gordon Christensen's practical clinical courses has some good hands-on ones out in Utah. Added plus is they have a significant new grad discount if you are less than 5 years out of school. Be prepared to spend a lot for any hands on courses but they are fun and worth it IMO
For implant surgery, go to the Pikos Institute in Trinity, Florida. Dr. Pikos has lectures, lab workshops, and live cases, all within a small atmosphere that allows direct interaction with him and his faculty.
