Dental Implants. A dental implant is an artificial tooth root that is placed into your jaw to hold a replacement tooth or bridge. Dental implants may be an option for people who have lost a tooth or teeth due to periodontal disease, an injury, or some other reason. Endosteal (in the bone): This is the most commonly used type of implant.
Lamellar structure. A schematic of a lamellar structure for a eutectic system. Lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. They are often observed in cases where a phase transformation front moves quickly, leaving behind two solid products, as in rapid cooling of eutectic (such as solder) or eutectoid (such as pearlite) systems.
The lamellipodium (plural lamellipodia) (from Latin Lamina - thin sheet, pod - foot) is a cytoskeletal protein actin projection on the leading edge of the cell.It contains a quasi-two-dimensional actin mesh; the whole structure propels the cell across a substrate (Alberts, et al., 2002).Within the lamellipodia are ribs of actin called microspikes, which, when they spread beyond the lamellipodium frontier, are called filopodia (Small, et al., 2002).rp2/3 complexes are present at microfilament-microfilament junctions in lamellipodia, and help create the actin meshwork. Arp 2/3 can only join onto previously existing microfilaments, but once bound it creates a site for the extension of new microfilaments, which creates branching (Weed, et al., 2000).
