Reply to Tim Dunmore re: light contacts Use a combination of fixed and removable. If, for example, the open contact is between the molar and premolar, bond a button or a hook on the palatal and buccal of the molar, construct an Essix retainer and cut off the segment distal to the premolar. Instruct the patient to wear 3/16 elastics from the buccal and palatal of the molar to either buttons bonded to the Essix retainer or small flaps cut out on the retainer. With a complaint patient this should work well. Kind regards.

Minor spacing:
In some cases you can simply wrap a figure 8  light ligature wire around the spaced teeth and use your fingers and the ligature tension to create the appropriate contacts. This seems too easy and it is very repeatable and successful. You may need to increase the tension a few times.
Let me know how it works for you.   Remember to remove the ligature wire to avoid perio problems.

Subject: Fluoride

Has anyone heard of any adverse reactions when an orthodontic patient in full braces uses MI Paste (Recaldent) with 0.05% Fluoride solution?  A dentist friend whose son is in full orthodontic tx (with another orthodontist) was using MI Paste to “help remineralize” certain hypocalcified areas.  He then stopped using this product and started using 0.05 % Fluoride rinses (from Oral B) for a while.  This was all initiated and prescribed by his mother, not the orthodontist.  Last week, he used both the MI Paste and the fluoride, one after the other, and immediately after he rinsed, according to his mom, his teeth became grey (she claims his normal shade of B2 became C4).  She tried pumicing the teeth, but that didn't help.  She took her son to the University of Toronto and had him examined by Dr. Hardy Limeback, who theorizes that maybe some metal particles from the brackets or wires or metal ligatures have found their way into the enamel as a result of the MI Paste's “remineralizing” action.  I'm just wondering if anyone has had any experience like this one.  If yes, is there a way to reverse this drastic change in tooth color?  Would bleaching or soflexing work?  Mom is really devastated and was in tears when she was telling me about this.  I guess this is a classic example of “a little knowledge is a dangerous thing”, but I would love to be able to help her out. 

Thank you,

Hi Tim,

Nice to see you around here. I use a standard Hawley (Adams on the 6's, with finger springs from the distal of the 7's activated to bring the 7 forward).... I find it works great, fast and easy. I once had a hard time to bring the 7 mesial (about 3mm to close). It was accomplished within 5 weeks with the H/. As for Bill Hyman and the question on closing mechanics. Most of my closing is on 16 x 22 ss with hooks distal to the laterals(sliding mechanics on Self Ligating SMART CLIP - 3M), but for certain patients as you mentioned, I use 16 x 22 TMA with T LOOPS (pre formed -ORMCO - and the distance between the loops is preset - just choose the right size). The wires already have a curve of spee incorporated (wire is preformed with a curve and posterior tow-in) and follow all of Burstone principles of biomechanics.
