在NTO雜誌裡,DR.林錦榮SHARE有關骨釘植入IZC(顴骨下脊)的一些概念,其原稿在下方的連結裡!!

~It’s outside of the root area. Unlike inter-radicular placement, the size has to be limited to 1.2mm ~ 1.5mm . Instead using a 2mmx 12mm stainless orthodontic bone screw for bicortical engagement avoids root damage and caused almost no fracture to the screw.

~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!
