Management of Grossly Decayed Mandibular Molar with Different Designs of Split Cast Post and Core

Figure 3

Line diagram showing different type of designs made according to the anatomy of root. In teeth with divergent roots the paths of insertion of the two posts (a) coincide with each other, so it is difficult to prepare the wax pattern. Hence in such cases the design in (b) is suggested, while in teeth with lesser divergence design in (c) is suggested.
