Evaluation of Implant Abutment-Level Digitalization Techniques

Sponsor: Hacettepe University

View on ClinicalTrials.gov

Summary

This methodological clinical study aims to evaluate digital workflows used for the intraoral digitalization of cement-retained implant abutments in situations where implant impression components are unavailable and abutment replacement is not feasible. Three digital impression workflows were compared through quantitative analysis of three-dimensional implant positions derived from digital datasets obtained using scan bodies and abutment-level scans. Implant positions were defined by virtual implant axes and analyzed using reverse engineering software. The study evaluates whether combined intraoral-extraoral abutment scanning provides comparable accuracy to direct intraoral abutment scanning.

Digital workflows using an intraoral scanner (TRIOS, 3Shape)

In this clinical study, three digital workflows were applied to each participant for the digitalization of cement-retained implant abutments. All digital impressions were obtained using an intraoral scanner (TRIOS, 3Shape). The workflows included: (1) intraoral scanning using the original scan body (Straumann), (2) direct intraoral scanning of the cement-retained abutment, and (3) a combined workflow involving intraoral and extraoral scanning of the abutment followed by best-fit alignment. Three-dimensional implant positions were defined by virtual implant axes derived from the digital datasets. Angular deviation analysis was performed using reverse engineering software to compare implant position outcomes among the digital workflows.
