Charlie,

No comments but more questions.  Tip Edge mechanics for significant Class II correction means upper 4's, lower 5's extracted and Class II elastics?  I certainly use those mechanics for many Class II's in my practice.  How does a .016 Niti torque the incisors?  Finally, is the slot size .022x.028?  You are practically filling the slot with the .021x.025 TMA.  How much larger is recommended in the Tip Edge technique?

When new ortho grads ask for advice, I always make sure to suggest that they have to contemplate how they plan on dealing with class II problems. To me that is 90% of orthodontics unless you happen to live south of McMurdo Sound where I understand no class II patients dwell. 

I've done it all: headgear, headgear bite plane, headgear Cetlin plate, Frankel, Bionator, Teuscher, Twin Block, Herbst, Jasper jumper, distal jet, pendulum, upper 7 extractions, etc. 

I do like distal jets for mild class II problems but I use Tip Edge braces and mechanics for significant Class II problems and it has really simplified things for me. Yes, I do sometimes extract only in the upper arch and according to Jay B that is the "Devil's Choice." 

Two changes I've made doing to Tip Edge and the reason I'm writing is to ask for comments: 

1. I use an 016 niti final underlay wire and it really seems to torque the incisors. I really like it 
2 and I routinely don't go much larger than a 21 x 25 TMA as a final main archwire except in deep bites where I need max bite opening. 

Comments?

Charlie,

Makes sense to me.  Richard Parkhouse uses .014 NiTi to underlay, but primarily because it's easier to pass.  I look at your list of solutions and haven't quite tried all of them, but definitely done the Cetlin, HG, various "functionals" and Herbst (and of course bone anchors and surgery).  Here in the land of whopper class II's, I have to admit, I've been impressed with Tip Edge for those cases treated by camouflage.  The 21 x 25 TMA makes sense as well.  Not sure how many comments you will get, since I don't think there are alot of Tip Edge "mechanics" on the listserve.

Kind Regards,

Paul M Thomas

I am glad to hear that someone with as much experience as you has settled on Tip Edge for Class II cases. I feel fortunate to have started with Tip Edge (thank you Columbia U) and skipped the Frankels, bionators, Twin Blocks, etc. I routinely use 016 underlay wires in the upper and as much as possible in the lower. Thanks to someone, possibly you Charlie, I feed the lower underlay arch in b/n the cuspid and lateral instead of b/n the incisors. I use SS arches 021x025, with reverse curves prn for maintaining bite opening in stage 3. I have never tried TMA wires as I have always thought they may not be stiff enough for stage 3. I try and get my bite opening done prior to placing a rectangular arch, as I feel torquing/uprighting tends to deepen the bite in some cases. Also, I find I have to reposition brackets, especially 3's and 5's, because I run out of bracket before I am uprighted. I guess I miss the Begg bracket here. But only here! So, I periodically place brackets erring on the side of over uprighting. I am usually not happy with my ClassII cases that I exo only upper 4's. I get to the end wishing I had exo'd in the lower because the upper ends up too "loose" and the lower too "tight". I tend to do upper 4's/ lower 5's more often than in the past, feeling very comfortable with tip edges ability to control anchorage properly. I have a case I need to post here when finished. It is an adult skeletal class III, missing lower 6's. I saw him about 5 years ago, and discussed surgery. He came in again last year. After seeing several molar exo cases at the tip edge course I decided to treat with tip edge plus,. We are about a year into treatment, well into stage III, and it looks fantastic. I was able to get some overjet, and the occlusion is falling into place. It looks so much nicer than cases I have treated exo'ing lower 4's. He is thrilled, commenting on how much his profile has changed. Makes my day!
