Abstract
Introduction: Conservative restoration of fractured anterior teeth is a challenge. Today is an era of beautification; even dentistry is moving towards better appearance. Therefore we are always in search of techniques and materials, which will lead to more natural appearance of teeth.
 Aim: To assess the break strength of maxillary focal incisors subsequent to reestablishing with four reattachment procedures (simple reattachment, internal grooving, over–contour, buccal chamfer with lingual over contour). And to compare the fracture strength obtained by reattached segments and to find the best technique for restoring fractured central incisor teeth.
 Result: In current in vitro study was directed to assess the crack strength of maxillary focal incisor teeth utilizing four distinct reattachment methods. Initial four gatherings were the experimental groups and fifth one was control bunch. The force required to fracture the reattached fragment was recorded in Newton.
 Conclusion: In light of results obtained and within the limitations of the present study: None of the reattachment procedures were able to regain the fracture strength as compared to the intact teeth. When compared to an intact tooth Buccal chamfer with lingual overcontour, and overcontour group had 60% recovery of fracture strength and Fracture strength of Buccal chamfer with lingual overcontour, and over contour was better than internal groove which was better than simple reattachment group.
