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 stability of the lamellar phases formed with the anionic surfactant sodium 4-(1â²-heptylnonyl)benzenesulfonate, the cationic surfactant didodecyldimethylammonium bromide, and the nonionic surfactant pentaethylene glycol mono-n -dodecyl ether (C 12 E 5) is reported as water is gradually replaced with propylene glycol.he stability of the lamellar phase is a function of the periodic repeat distances and surfactant head group areas as measured by small angle X-ray scattering, and the results are discussed in terms of the inter-and intra-bilayer interactions.
