My son got crowed and pop-up teeth, I’ve searched Damon system web site w/ zip code 20841, and I visited all the doctors listed, Dr. Dillon is the only one truly practice Damon system, you don’t choose between elastic ligature (bands or ties) and self-ligating brackets, he used self-ligating brackets, titanium memory-wire and some tiny coils to create space needed. All other doctors told me my son’s problem can’t be fixed by Damon system, and they wanna pull out 2 or 4 teeth and slenderizing/Inter Proximal Reduction (IPR) …go figure
