Alternative approach to salvaging an implant with a fractured screw fragment: A clinical report

Published:February 28, 2020DOI:https://doi.org/10.1016/j.prosdent.2019.12.015

      Abstract

      Managing fractures of implant abutment screws is challenging because of the uncertainty associated with the removal of the fractured screw fragments. In case of unsuccessful retrieval of the fractured fragment with known techniques, removal and replacement of the implant becomes traumatic and financially burdensome to the patient. This clinical report describes a conservative solution for the management of nonretrievable fractured screws by reconnecting the prostheses to the existing implants by using cut screws. This alternative, cost-effective method obviates the need for surgery and has proved successful and satisfactory for patients.
