11. 11 Thread Design Defines the interaction between the implant and bone macrostructure “Machine screw” thread versus “wood screw” thread: Machine screw thread: Screw and substrate have the same or similar mechanical properties. Threads are small, closely packed, and v-shaped. Wood Screw: Screw and substrate are different materials (substrate has lower stiffness). Threads are larger, with larger pitch. Threads designed to dig into the substrate. Courtesy of Jack Ricci PhD (NYU)
12. 12 Thread Design Courtesy of Jack Ricci PhD (NYU) Square thread similar “Wood screw” thread designed for axial compression F S C bone Reverse buttress design has larger, deeper thread, and a lower surface face designed to provide compressive force rather than shear force.
13. 13 Laser-Lok® microchannels Controls epithelial downgrowth Attaches and retains crestal bone Patent# 6,454,569 & 6,419,491
14. 14 Old and New Microtextures Courtesy of Jack Ricci PhD (NYU) RBT Machined surface
16. 16 Biologic width around traditional implants Tissue level at the time of placement Bone level at the time of placement Microgap Is there a better way?
18. 18 Laser-Lok – proprietary Only surface of its kind Microgrooved surfaces for mechanical stability Patented FDA cleared claims Inhibit epithelial downgrowth Attach/retain crestal bone
19. 19 In vitro studies of cell response to surface microtexture: cells on controlled microtextures Microgrooved surfaces produced from silicon wafer templates. Microgrooves inhibited colonization and caused directional colony formation (Contact Guidance). Optimal groove sizefor inhibition of fibroblast colonization was 6-12 µm widthand >2 µm height.
