Bone Compression Kit enhances primary stability in type 3 and type 4 bone. The gradual condensation process applied on the osteotomy walls prior to implant placement, results in increased bone density around the implant and thus, great primary stability. In addition, the unique design of the compression screws allows for closed sinus augmentation procedures. The screws engage bone, applying an upwards vertical force to elevate the sinus floor, facilitating delivery of augmentation materials to the site. The Bone Compression Kit includes the following tools: MO-CO160 Convex compress screw Ø1.80-2.90mm MO-CO200 Convex compress screw Ø2.30-3.30mm MO-CO240 Convex compress screw Ø2.70-3.70mm MO-CO280 Convex compress screw Ø3.10-4.50mm MO-SO300 Concave sinus screw Ø3.00mm MO-SO350 Concave sinus screw Ø3.50mm MO-SO400 Concave sinus screw Ø4.00mm MT-SMD10 Spade marking drill MT-HSI10 Short insertion tool MT-HLI10 Long insertion tool MT-LRH20 Long insertion tool MT-SRH20 Short insertion tool MT-RI030 Monoblock ratchet
