Objective: Implant abutment screws can fracture due to various biomechanical factors. Improper fit of the prosthesis, inadequate seating of the abutment, occlusal interference, and manufacturing errors are some of the causes that can result in an abutment screw fracture. Retrieval of the retained fractured abutment screw is quite challenging to the clinician. The objective of this review is to provide information on various fractured abutment screw retrieval techniques reported in literature and to formulate a structured treatment protocol for the management of fractured abutment screws. Materials and Methods: An electronic search of Scopus and PubMed databases was performed for articles between January 1989 and December 2021 using the keywords “Implant screw fracture” and “screw retrieval.” Results: Most of the articles were of the opinion that abutment screw fractures occurred due to screw loosening. Both conservative approaches and the use of commercial retrieval kits have been advocated to retrieve the fractured abutment screws. Based on various review articles, an innovative novel technique to retrieve an abutment screw fractured due to excessive torque was devised in our unit. Conclusion: Although clinicians can use various techniques to remove fractured abutment screws, every effort should be made to eliminate the cause of screw fracture. Retrieval of the broken screw fragment should be done judiciously to prevent any internal damage to the implant structure.
