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.
Lamellar wasn't just made of metal plates. It was also made with leather and bamboo scales. In Japan, this was a cheaper way to make a massive amount of armor for large amounts of Samurai, and was actually far more typical than ones made with metal, due to it being both cheaper and lighter.
