The syringe delivery method is most commonly used with light-bodied impression materials due to its ability to provide precision and accuracy in capturing details. Light-bodied materials are designed to flow easily and can effectively fill in fine details, making the syringe method ideal for applying the material directly onto the prepared teeth or area. This technique allows for the impression material to closely adapt to every contour, ensuring a more accurate representation of the dental structures.

In contrast, tray methods generally utilize heavier or regular-bodied materials that do not require the same level of detail as light-bodied materials. While trays are used in conjunction with impression materials, they are less effective for capturing intricate details because they do not provide the same level of flow and adaptability. Similarly, putty is often used for more rigid impressions or in scenarios where detail is less critical, and vacuum methods are not standard for applying impression materials directly as they typically assist in creating a negative pressure to hold materials in a tray rather than delivering them with precision.
