NCT07119281 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

Last updated 2025-09-08

No results posted yet for this study

Summary

The study aims to identify which retraction method offers optimal balance between tissue displacement, scan clarity, and patient comfort, particularly in the esthetic zone, while avoiding the use of CBCT. Results will guide clinicians in selecting the most effective and minimally invasive approach for digital impression workflows.
