Conservative Retrieval of Fractured Abutment Screw – A Case Report - Abstract
Failure of implant components can occur due to biological or mechanical factors. Biological factors comprise ineffective osseointegration and occurrence of periimplantitis. Mechanical failures include crown breakage, framework fracture, screw loosening, and screw fracture. Dental implants can be rendered ineffective due to such complications related to implant components. One of the most serious mechanical consequences of implant treatment is screw loosening and fracture, which is now becoming increasingly common. Removal of fractured fragments is deemed necessary for the sake of prosthetic restoration. Various techniques have been defined for the removal of the fractured segment from the screw hole. This case report presents a rare incident of implant abutment screw fracture and the utility of a piezoelectric ultrasonic scaler in conservatively retrieving the fractured abutment screw fragment.
