It provides a choice of lordosis, adjustable in situ from 0 to 11°. It's also an anti-back-out teeth giving an excellent primary stability of the implant. It has optimized bone fusion with excellent secondary stability owing to the wide graft chamber of the implant (from 212 mm3 to 1318 mm3). Cages are supplied non-sterile with 2 sizes: standard 13 mm and narrow 10 mm with 4 heights in order to adjust to all corrections.
