Background: The advancement of dental implants marks a significant milestone in modern dentistry, offering an effective solution for tooth replacement while improving both functionality aesthetics. Despite their high success rates, dental implants are susceptible to various complications, including mechanical issues. Among the most common mechanical complications is implant screw loosening and fracture, which compromises the structural integrity of the dental implant and may lead to implant failure. Aim of study: To establish a protocol for managing implant abutment screw fractures by removing the fractured part without compromising the implant or its functionality. Methodology: A case highlights the loosening of implant screws as a critical concern in restorative dentistry. The fractured abutment screw was successfully retrieved using an ultrasonic tip, presenting an effective and straightforward sequential protocol for retrieving fractured abutment screws while preserving the integrity of the implant. Results: Using The ultrasonic tip technique demonstrates a highly significant impact by providing a simple, effective, conservative, noninvasive, and predictable protocol for removing fractured screw abutments from dental implants. Furthermore, this technique enables clinicians to reuse the same implant without causing surgical trauma or imposing any financial burden on the patient. Conclusion: Abutment screw fractures represent a mechanical failure associated with dental implants. Retrieving fractured abutment screw without causing damage to the internals of the implants poses a significant challenge for clinicians, often requiring considerable time and effort to address the underlying cause of the fracture.
