Abstract : Background: Endodontically treated teeth usually require special techniques to be restored and regain function. Nowdays endodontically treated teeth are treated on method of adhesion rather than mechanical retention.Endocrown is the new method to restore endodonticaly treated teeth with good restention and high success rate. Endocrown are adhesive restoration it result in minimal microleakage. Hence it can lead to high success rate. Case presentation :In case I - A 23‑ years‑ old female patient visited with a chief complaint of pain in the lower right back region of the jaw. On clinical evaluation, grossly carious 46 was seen. So root canal treatment was done with 46. Then full ceramic endocrown post endodontic restoration was planned. In case II- A 50‑ year‑ old male patient visited with a chief complaint of pain in the lower right back region of the jaw. When examined clinically, grossly carious 46 was observed. Root canal treatment with 46 was planned. Then full ceramic endocrown post endodontic restoration was planned. In case III- A 20‑ year‑ old female patient visited with a chief complaint of pain in the upper left back region of the jaw. On clinical evaluation, grossly carious 26 was observed. Root canal treatment with 26 was planned. Then metal - ceramic endocrown post endodontic restoration was planned. In all the three cases in second visit glass ionomer cement was used to block the orifices and obtain even surface without any undercuts in pulp chamber. Then endocrown preparation was done. The finished line appeared as a regular line with a sharp edge. A 1‑ mm gutta‑ percha was removed from the canals using a heated plugger. After the completion of tooth preparation impression was made with polyvinyl siloxane silicone of light and putty consistency using a double‑mix single‑ stage technique. Master cast was prepared and endocrown was fabricated in laboratory. In third visit endocrown trial was done in all the three cases and cementation was done and post cementation IOPA was taken. Conclusion: Endocrown is the new treatment modality for grossly destructed endodontically treated teeth. Both metal-ceramic and zirconia endocrowns provides better retention and stability with minimal loss of tooth structure.
