The stability of the connection between different implant parts is important for the overall success of the prosthesis. This is especially true for single-tooth restorations, where a strong interlock between the implant and abutment is necessary. A common problem associated with single-tooth implants has been the loosening of abutment or fracturing of retaining screws. Inadequate torquing force applied to the screw is the most important reason for screw loosening and fracture. Structural inadequacy can also lead to screw fracture. Screw fracture occurs more readily with a loose screw as it is more prone to excessive lateral loads. Screw loosening can be an inconvenience to the patient and the practitioner. It is a fact that screw loosening occurs in single-implant restorations regardless of the implant-abutment connection geometry even if proper antirotational features and torque are provided. The management of a patient who had reported with fracture of an abutment screw is presented in this article. [ABSTRACT FROM AUTHOR] |
