Abstract

Background: This case report presents a novel approach to managing abutment screw fractures in dental implants, emphasizing the reuse of the patient’s existing crown with cement retention to reduce both cost and treatment time.
Case Presentation: A 39-year-old woman presented with a fractured abutment screw in an implant at position #19. After multiple failed attempts to remove the fractured screw using hand instruments and ultrasonic devices, we opted for a cement-retained solution. In the standard approach, a new post, core, and crown would typically be fabricated. However, as the existing abutment crown demonstrated a good fit, complete seating, and acceptable aesthetics, we decided to reuse the crown. A custom pin was fabricated to secure the crown to the fixture, thereby reducing the need for additional procedures and lowering the cost for the patient.
Conclusion: Reusing the previous abutment crown with cement retention can be a viable option in cases of abutment screw fracture, offering an effective solution to reduce both cost and treatment time. This method provides an alternative to fabricating a new post, core, and crown.
