What are the advantages of polysulfide polymer in impression making?

Polysulfide polymer is widely used in impression making due to its unique properties that facilitate accurate and detailed impressions. One of its primary advantages is its ability to capture fine details, especially in challenging areas such as sulcular zones or highly contoured surfaces. The material effectively flows into these spaces, allowing for the reproduction of minute details without trapping air, which is crucial for achieving an accurate fit for prosthetic devices.

The enhanced capability to handle complexities in gingival sulcus and other intricate anatomical features makes polysulfide a preferred choice among dental professionals. This property is instrumental in achieving precise margins in crown and bridge work, thus ensuring a better final result in prosthetic dentistry. Moreover, polysulfide impressions can provide a high level of dimensional stability once set, contributing to the overall effectiveness of the impression process.

Understanding these advantages allows dental practitioners to make informed decisions about which materials to use for specific situations, significantly impacting the quality and longevity of prosthetic restorations.
