Which material is most effective for enhanced impression making in sulcular areas and pinholes?

Polysulfide polymer is recognized as the most effective material for enhanced impression making, particularly in sulcular areas and pinholes, due to its unique properties. This material exhibits excellent flow characteristics, allowing it to capture fine details and undercuts more effectively than other impression materials. The high flexibility and ability to stretch without tearing enable polysulfide to accurately reproduce the intricate contours of the tooth and surrounding soft tissue, making it particularly suitable for capturing sulcular areas, which are often challenging to impress.

Polysulfide also has a longer working time compared to other materials, allowing for an extended manipulation period to ensure optimal placement and adaptation to the area being impressed. Its adhesive properties help it to adhere well to the tooth surface, further enhancing its ability to capture accurate impressions in complex areas, such as pinholes.

In contrast, irreversible hydrocolloid, while useful for many situations, does not provide the same level of detail and accuracy in areas requiring high precision. Heavy-bodied tray materials, while effective in some cases, may not capture intricate details due to their viscosity. Gypsum, primarily used for casting models, does not serve as an impression material and therefore cannot fulfill the requirements for capturing anatomical details.
