To knot the thread: Insert the needle through the front and back of the fabric at a point directly next to your final insertion point.
We did not prepare the trapezium bone by threading before insertion of the cup.
In cortical bone, this screw nut is threaded at insertion, and can have considerable strength.
Eligibility criteria comprised clinical studies involving patients who received MIs for orthodontic anchorage, with data for categories of MI dimension, shape, and thread design and insertion site, and evaluated by assessment of primary and secondary stability.
The MIZ-lift uses my concept of a stable fixation point at the temporal fascia but has more similarity to Isse's technique in that they both use a surgical dissection at the temple, separation of superficial and deep tissue planes, insertion of the threads, and suture of the threads down to the deep temporal fascia.
Klahn et al. (2012) recently published findings of progressive aseptic loosening of the Elektra cup after more than 2 years, but they used threading of the bone before insertion of the cup.
We designed the mini-implant as a small head-type tapered pure titanium screw with external diameters of 1 and 1.3 mm, lengths of 6 and 8 mm, threaded deepness flight depth of 0.2 mm, threaded angle of 60°, and thread interval of 0.5 mm, with angulation of insertion to the vertical plane, at 30° and 60° (Fig. 1).
The femur was stabilized by retrograde intramedullary insertion of a fully threaded 1.6-mm Kirschner wire, leaving an 8-mm gap.
The authors have presented an elegant technique of thread-lifting that involves first partial dissection in the temporal region and then closed insertion of their modified MIZ threads into the distal part of the face, with the deep temporal fascia providing a stable fixation point for the threads.
We demonstrated that inexpensive high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles.
