Verification Index for the Repositioning of a Single Implant Analog in the Correct Place. A Clinical Case Report

Background/Objectives: Implant impressions can present inaccuracies, affected by many factors, such as impression technique, impression material, parallelism or not among the implants. The use of a verification index can assess the accuracy of the mastercast, and can be used in order to adjust the inaccuracy of the mastercast. This article presents a novel technique for fabricating a verification index, followed by implant analog repositioning, which can be used in case of an impression inaccuracy. Case Presentation: A patient with moderate gag reflex received an implant. The impression of an implant and a prepared tooth was made. At the metal try-in an inaccuracy of the mastercast was found, attributed to the final impression. A technique was illustrated, describing a poly-methel methacrylate (PMMA) transfer index fabrication, as well as the implant analog repositioning in the removable die of the master cast. This method can skip the remaking of a new impression. The novelty in this technique is the repositioning of the implant analog in the removable die. Conclusions: This is a viable technique, which can replace the need for a new impression, and therefore skip one appointment. It is important for patients with moderate to severe gag reflex, since it can minimize the discomfort and stress for the patient and the dentist.
