Three-dimensional inlay-guided endodontics applied in variant root canals: A case report and review of literature

Figure 7 Restoration of the maxillary left second molar. A: A silicone rubber model of the tooth; B and C: Because of the variation in the root canal and the large angle of bifurcation, the common path of insertion is inconsistent; therefore, “plug-in” post-core restoration is selected; D: The post-core is inserted into the tooth, the abutment tooth is prepared, and the tooth is restored with an all-ceramic crown.
