Hexagon, to facilitate implant insertion, indexation and stability of prosthetic systems. Highly polished surface, 0.9 mm high, to accommodate the biological space. Micro thread to promote cortical bone stimulation. The sand blasting surface. Cylindrical-conical profile and thread with variable depth for best anchor in spongy bone. The asymetrical macro-thread resultsin enhanced initial stability. High-strength material : - EVL® Konik ISO 5832-3 Titanium (A.S.T.M.grade 5) Reverse flutes to make the osteotomy easier. The rounded apical end largely prevents injury to the sinus membrane.
