Nankali Post and Core Classification

Here Nankali Post and Core classification is illustrated and all systems are divided into two main groups: prefabricated and those that are made in laboratories 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 following steps it is clearly displayed whether the system is symmetrical or non-symmetrical which is another important fact to consider.

In the Nankali post and core classification the outline surfaces, threaded, smooth and serrated are profoundly discussed, in addition to the other mentioned directions.
