Aims: The aim of this study is to compare in vitro the fracture resistance of the endodontically treated tooth restored with a novel design Sharonlay, with the two component restorative method, i.e., post with separate onlay, and onlay without post. Subjects and Methods: 45 single-rooted mandibular second premolars were taken, and root canal treatment was performed. Teeth were then randomly divided into three groups (n = 15) based on the type of restoration given: Group I - metal onlay with cast post extension (Sharonlay), Group II - metal onlay with prefabricated metal post (Mani post system), Group III - metal onlay over endodontically treated tooth obturated with Gutta-percha (control group). Fracture resistance was checked using the Instron universal testing machine and the fracture patterns were analyzed. Results: According to the values recorded, Group I showed maximum mean fracture resistance followed by Groups II and III. Statistically significant difference was found between Groups I and II and Groups I and III and statistically significant difference was found between Groups II and III. Conclusion: A single unit component Sharonlay, gives higher fracture resistance to a premolar as compared to (a) metal onlay with prefabricated metal post and (b) metal onlay over endodontically treated tooth.
