RE: Bonded lower retainers.
I think it was Zachrison that described a bonded 3x3 using .032 TMA bonded only to the cuspids. I place these on nearly 100% of my patients and have placed hundreds over the past 10 to 15 years. Before that, I had used some .0175 twist retainers bonded to every tooth but gave up after too many came back with one or two teeth off the wire. Oral hygiene was a problem with them. There is absolutely no reason to bond to every incisor. Lower relapse does not occur in my office and I rarely have any breakage of the 3x3's. Oral hygiene is great. The TMA allows the cuspids to "flex" without wire breakage. The wire has to be adapted properly to contact each anterior tooth as incisally as possible without being visible from the front. Bend the ends of the wire slightly toward the gingiva at the interproximal of the lateral and cuspid and flame the ends of the wire for a less bulky finish line. Cure one cuspid first and then the key is that the wire has to be pulled very, very tight against the incisors with floss while light curing the second of the two cuspids. The only times I have had any relapse of an incisor with this method is when I did not pull hard enough on the floss. We'll quickly place as many as seven in one day. Give this a try and I promise you will never go back to removable lower retainers or bonding every incisor.

Concerning the severe Class II molar discrepancy, the most precise way is to measure the discrepancy in millimeters instead of making up a name for it.
