Abstract

Purpose: The precision of implant prostheses, which requires accurate impression acquisition, can significantly impact a patient’s treatment prognosis. This study therefore aimed to compare the accuracy of the scan data obtained using an encoded healing abutment with a scan body for digital implant impressions.

Materials and Methods: A resin model was constructed using an implant analog (ISLA500, Neobiotech) at sites #15, #17, and #21. After the scan body was connected to on the model, it underwent scanning using a model scanner to produce reference data. The scan body (IS D5, Neobiotech) and encoded healing abutment (IS 4004S, Neobiotech) were connected to the model, and 20 scans per each group were performed using an intraoral scanner (Trios^®, 3Shape Dental Systems). The data obtained from these two groups were compared with the reference data using two-way analysis of variance and t-tests.

Results: The mean distance from the reference point was 0.089 mm in the scan body group and 0.217 mm in the encoded healing abutment group, indicating that the scan body was closer to the reference value than the encoded healing abutment.

Conclusion: Digital implant impressions obtained with the scan body were more accurate than those acquired with the encoded healing abutment when taking digital implant impressions.
