The Nankali post and core classification is the most advanced classification that is used in restorative dentistry for grouping different types of post and cores. ==Nankali Post and Core classification== Here Nankali Post and Core classification is illustrated. As it can be observed all systems are divided into main two groups prefabricated (which is made in factories) and those posts that are made in laboratory or in surgeries. In the next step each group is divided into two subgroups according to their counter-sink constructions including their position. In the other steps either the system is symmetrical or non-symmetrical is another important fact that is pointed out. In the Nankali post and core classification the outline surfaces, threaded, smooth and serrated are profoundly discussed, in addition to the other mentioned directions. Because posts can be made from different justified dental materials such as Stainless Steel, Titanium, Titanium Alloy, Gold-Plated brass, Carbon and Ceramic, to avoid complications in understanding this classification the choice of material is not placed. All posts and cores can also be made as a one part or more parts. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nankali post and core classification」の詳細全文を読む スポンサード リンク
