Abstract
Introduction: Retrieving implant-supported restorations can be very challenging due to variations in implant systems, implant angulation, and the location of screw access. This procedure can introduce potential complications during the retrieval process, such as damaging the screw head or the internal threads of the implant. Methods: The utilization of a retrieval guide for accurate positioning of a cement-retained implant crown. In this technique, intra-oral scans, along with cone-beam radiographs, were utilized for precise identification of the screw access position. Results: In this clinical report, the successful retrieval of a cement-retained implant crown was described using a novel digital retrieval system. This clinical report presents a proof-of-concept technique for retrieving implant-supported crowns. Conclusion: This technique paper presents a potentially predictable innovative approach to identifying the screw access position in old cement-retained implant-supported crowns. Successful retrieval of a cement-retained crown was completed safely. Clinical significance: The use of this guide could potentially eliminate the risk of damaging the head of the screw, which can eventually lead to impossible retrieval.
