简要总结

Accurate impressions are crucial for the success of fixed dental prostheses. Among the commonly used techniques with polyvinyl siloxane (PVS) materials are the single-stage and two-stage putty-wash methods. This study compares the accuracy of these two approaches in capturing fine details necessary for precise restorations.
