~It can be as an excellent anchorage unit as inter-radicular placement of orthodontic bone screws.
~It’s much better than inter-radicular placement of orthodontic bone screw for distalization of the whole upper arch.
~The 2mx 12mm stainless steel orthodontic bone screw requires neither incision nor tissue punch. Self-drilling is sufficient.
~IZC placement over mesiobuccal root area of upper second molar is better than over that of the upper first molars.
~Better be placed over the attached gingiva area.
~Contra indicated for patients of a very young age and with low sinus floor among the roots of maxillary molars.
~Using about 10~ 12oz (or 284 -340gm ) to distalize the whole upper arch. An excessive force will result in failure!FROM~~Summary of the new IZC placement(from NTO)
